请问什么是MVA?
MVA全称为(Multi-domain VerticalAlignment),是一种多象限垂直配向技术,属于VA型面板的其中一种。MVA是较早投入应用的广视角液晶面板,由日本富士通公司开发,目前生产MVA的厂家有奇美电子和友达光电等。它是利用突出物使液晶静止时并非传统的直立式,而是偏向某一个角度静止;当施加电压让液晶分子改变成水平以让背光通过则更为快速,这样便可以大幅度缩短显示时间,也因为突出物改变液晶20ms以内。分子配向,让视野角度更为宽广。在视角的增加上可达160度以上,反应时间短。2023-07-07 10:49:173

Excel vba里怎么设置单元格的内容对齐方式
具体步骤如下:1、首先打开需要编辑的Excel表格,进入到编辑页面中。2、然后点击打开开发者工具中的“Visual Basic”。3、然后在弹出来的窗口中点击打开插入中的“模块”选项。4、然后在弹出来的窗口中点击输入下面的代码:Sub cell()Dim icell As Integer, hcell As IntegerFor icell = 4 To 35If UCase(Cells(icell, 1).Value) = "SAT" Or UCase(Cells(icell, 1).Value) = "SUN" ThenCells(icell, 1).Value = UCase(Cells(icell, 1).Value)For hcell = 1 To 21Cells(icell, hcell).Interior.Color = RGB(200, 200, 200)Cells(icell, 1).HorizontalAlignment = xlCenterCells(icell, 1).VerticalAlignment = xlCenterCells(icell, 1).Font.Bold = TrueNextEnd IfNextEnd Sub就可以了。2023-07-07 10:49:412
什么是显示器最佳视角?
液晶显示屏的视角角度视角角度乃是评估LCD显示器的主要项目之一。虽然能够从各种角度观赏CRT显示器所呈现的影像,不过LCD显示器却必须从正前方观赏才能够获得最佳的视觉效果。如果从其它角度看,则画面的亮度会变暗(亮度减退)、颜色改变、甚至某些产品会由正像变为负像。 直到不久之前,采用无源矩阵式的旧型机种仍有上述问题。有源矩阵式TFTLCD显示器的这种现象就比较轻微。某些较新型的桌上型产品,尤其是17英寸以上的机种,采用in-plane交换技术来扩大画面的观赏角度。如此一来,效果最好的桌上型显示器,其观赏角度已经能够逼近CRT显示器,约为左右两侧各80度,也就是水平观赏角度为160度,几乎能够从任何角度看到画面的内容。一般地,140至160度的可视角度即成为大尺寸LCD显示器的基本指标。对于较小尺寸的15英寸或15英寸以下的LCD显示器,120度的可视角度便足以显示完整的画面。左右两侧的观赏角度一般会大于上下的观赏角度,也就是垂直的观赏角度小于水平观赏角度(一般介于120至140度之间)。尽管如此,越来越多的LCD显示器强调其水平与垂直观赏角度相同。在购买能够将画面由横式旋转为直式的产品之前,一定要先比较其水平与垂直的观赏角度是否相同。因为旋转前的垂直观赏角度,在旋转后就成为水平观赏角度了。有一点值得特别注意,各厂商测量观赏角度的方法不太相同,所以产品规格书上的数值仅供参考。某些厂商以画面中心点为基准,而有些则是分别以上下左右四个边缘的数值予以平均而得。更糟糕的是,目前对?quot;可观赏"的定义并不明确。某些厂商系以画面亮度减半为标准;也有厂商则是以画面的对比为标准,如15∶1、10∶1或5∶1。由于认定标准较为主观,所以光看规格说明书反而会被误导。VESA发表的测量观赏角度标准,目前尚未被所有厂商所全面采用。为今之计,只有在购买前尽可能实地参观比较。2023-07-07 10:51:533
手机屏幕材质的区别
主要种类有:1、LCD液晶显示屏LCD(Liquid CrystalDisplay)的全称是液晶显示器,是现在用的比较多的手机屏幕材料,特点是价格便宜,使用普及广泛,在显示的时候需要有背光的支持。2、TFT屏TFT(Thin Film Transistor)即薄膜场效应晶体管,属于有源矩阵液晶显示器中的一种。TFT液晶显示屏的特点是亮度好、对比度高、层次感强、颜色鲜艳,但也存在着比较耗电和成本较高的不足。3、IPS屏IPS俗称“Super TFT”,是由TFT升级而来的一种技术,本质还是TFT屏幕,只不过是采用IPS技术的TFT屏。相对于普通的TFT屏,它拥有可视角度大、色彩还原准确、触摸无水纹、环保省电等优势。4、SLCD屏SLCD是拼接专用液晶屏,是LCD的一个高档进阶品种,特点是色彩更暖,还原真实,更自然,适合人眼观看。5、OLED屏OLED( OrganicLight-Emitting Diode)指有机发光二极管,OLED无需背光支持,具备自发光性,同时拥有广视角、高对比、低耗电、高反应速率以及全彩化、制程简单等优点。6、AMOLED屏AMOLED屏幕拥有可弯曲,广色域的特性,显示的颜色更加鲜艳,并且具有自发光低功耗等优点,已经成为主流高端手机热选。应用手机屏幕的智能手机在出厂前都需要经过测试,手机屏幕的质量和性能都至关重要,手机厂商对这一环节也相当重视,大电流弹片微针模组在智能手机屏幕测试中,起到连接导通的作用,可以有效解决手机屏幕测试问题。2023-07-07 10:52:2310

如何使用NSString在 drawInRect中居中
1. 纵你必须做你自己(的观点+字符串)/ 2的高度(高度)。卧式您可以这样做: NSMutableParagraphStyle *style = [[NSParagraphStyle defaultParagraphStyle] mutableCopy]; [style setAlignment:NSCenterTextAlignment]; NSDictionary *attr = [NSDictionary dictionaryWithObject:style forKey:NSParagraphStyleAttributeName]; [myString drawInRect:someRect withAttributes:attr]; 2. 这适用于水平 [textX drawInRect:theRect withFont:font lineBreakMode:UILineBreakModeClip alignment:UITextAlignmentCenter]; 3. 马丁斯答案是相当接近的,但它有一些小错误。试试这个: NSMutableParagraphStyle* style = [[NSMutableParagraphStyle alloc] init]; [style setAlignment:NSCenterTextAlignment]; NSDictionary *attr = [NSDictionary dictionaryWithObject:style forKey:NSParagraphStyleAttributeName]; [myString drawInRect:someRect withAttributes:attr]; [style release]; 你必须创建一个新的NSMutableParagraphStyle(而不是默认的段落样式马丁建议)[NSMutableParagraphStyle defaultParagraphStyle]返回NSParagraphStyle,它不具有另外,你不需要在字符串@"NSParagraphStyleAttributeName"-刚NSParagraphStyleAttributeName。 4. 此作品 CGRect viewRect = CGRectMake(x, y, w, h); UIFont* font = [UIFont systemFontOfSize:15]; CGSize size = [nsText sizeWithFont:font constrainedToSize:viewRect.size lineBreakMode:(UILineBreakModeWordWrap)]; float x_pos = (viewRect.size.width - size.width) / 2; float y_pos = (viewRect.size.height - size.height) /2; [someText drawAtPoint:CGPointMake(viewRect.origin.x + x_pos, viewRect.origin.y + y_pos) withFont:font]; 5. 正确的答案是:-drawInRect:withFont:lineBreakMode:alignment:我还创建了一个小类别垂直如果你喜欢它,继续前进:) // NSString+NSVerticalAlign.h typedef enum { NSVerticalTextAlignmentTop, NSVerticalTextAlignmentMiddle, NSVerticalTextAlignmentBottom } NSVerticalTextAlignment; @interface NSString (VerticalAlign) - (CGSize)drawInRect:(CGRect)rect withFont:(UIFont *)font verticalAlignment:(NSVerticalTextAlignment)vAlign; - (CGSize)drawInRect:(CGRect)rect withFont:(UIFont *)font lineBreakMode:(NSLineBreakMode)lineBreakMode verticalAlignment:(NSVerticalTextAlignment)vAlign; - (CGSize)drawInRect:(CGRect)rect withFont:(UIFont *)font lineBreakMode:(NSLineBreakMode)lineBreakMode alignment:(NSTextAlignment)alignment verticalAlignment:(NSVerticalTextAlignment)vAlign; @end // NSString+NSVerticalAlign.m #import "NSString+NSVerticalAlign.h" @implementation NSString (VerticalAlign) - (CGSize)drawInRect:(CGRect)rect withFont:(UIFont *)font verticalAlignment:(NSVerticalTextAlignment)vAlign { switch (vAlign) { case NSVerticalTextAlignmentTop: break; case NSVerticalTextAlignmentMiddle: rect.origin.y = rect.origin.y + ((rect.size.height - font.pointSize) / 2); break; case NSVerticalTextAlignmentBottom: rect.origin.y = rect.origin.y + rect.size.height - font.pointSize; break; } return [self drawInRect:rect withFont:font]; } - (CGSize)drawInRect:(CGRect)rect withFont:(UIFont *)font lineBreakMode:(NSLineBreakMode)lineBreakMode verticalAlignment:(NSVerticalTextAlignment)vAlign { switch (vAlign) { case NSVerticalTextAlignmentTop: break; case NSVerticalTextAlignmentMiddle: rect.origin.y = rect.origin.y + ((rect.size.height - font.pointSize) / 2); break; case NSVerticalTextAlignmentBottom: rect.origin.y = rect.origin.y + rect.size.height - font.pointSize; break; } return [self drawInRect:rect withFont:font lineBreakMode:lineBreakMode]; } - (CGSize)drawInRect:(CGRect)rect withFont:(UIFont *)font lineBreakMode:(NSLineBreakMode)lineBreakMode alignment:(NSTextAlignment)alignment verticalAlignment:(NSVerticalTextAlignment)vAlign { switch (vAlign) { case NSVerticalTextAlignmentTop: break; case NSVerticalTextAlignmentMiddle: rect.origin.y = rect.origin.y + ((rect.size.height - font.pointSize) / 2); break; case NSVerticalTextAlignmentBottom: rect.origin.y = rect.origin.y + rect.size.height - font.pointSize; break; } return [self drawInRect:rect withFont:font lineBreakMode:lineBreakMode alignment:alignment]; } @end 6. 嗯,drawInRect是唯一的好基本的文本绘制(换句话说,系统决定在何处放置您的文字)-常画你想要的文字定位是简单地计算出你想要它什么指向的NSString的drawAtPoint的唯一途径:withAttributes :。 此外,的NSString的sizeWithAttributes是你最终不得不做drawAtPoint任何定位的数学。 祝你好运! 7. [NSMutableParagraphStyle defaultParagraphStyle]不会[NSMutableParagraphStyle new]同时,它只会出现水平适用于drawInRect,不drawAtPoint(我怎么知道:-) 8. 下面的代码段用于绘制文本居中的注释自定义图像作为参考: CustomAnnotation.h @interface CustomAnnotation : MKAnnotationView [...] CustomAnnotation.m [...] - (void)drawRect:(CGRect)rect { ClusterAnnotation *associatedAnnotation = (CustomAnnotation *)self.annotation; if (associatedAnnotation != nil) { CGContextRef context = UIGraphicsGetCurrentContext(); NSString *imageName = @"custom_image.png"; CGRect contextRect = CGRectMake(0, 0, 42.0, 42.0); CGFloat fontSize = 14.0; [[UIImage imageNamed:imageName] drawInRect:contextRect]; NSInteger myIntegerValue = [associatedAnnotation.dataObject.myIntegerValue integerValue]; NSString *myStringText = [NSString stringWithFormat:@"%d", myIntegerValue]; UIFont *font = [UIFont fontWithName:@"Helvetica-Bold" size:fontSize]; CGSize fontWidth = [myStringText sizeWithFont:font]; CGFloat yOffset = (contextRect.size.height - fontWidth.height) / 2.0; CGFloat xOffset = (contextRect.size.width - fontWidth.width) / 2.0; CGPoint textPoint = CGPointMake(contextRect.origin.x + xOffset, contextRect.origin.y + yOffset); CGContextSetTextDrawingMode(context, kCGTextStroke); CGContextSetLineWidth(context, fontSize/10); CGContextSetStrokeColorWithColor(context, [[UIColor whiteColor] CGColor]); [myStringText drawAtPoint:textPoint withFont:font]; CGContextSetTextDrawingMode(context, kCGTextFill); CGContextSetFillColorWithColor(context, [[UIColor blackColor] CGColor]); [myStringText drawAtPoint:textPoint withFont:font]; } }2023-07-07 10:54:061

外星人屏幕用的是WVA是什么意思
应该是MVA技术。它是一种显示技术。MVA技术(Multi-domainVerticalAlignment,多象限垂直配向技术)可以说是最早出现的广视角液晶面板技术。该类面板可以提供更大的可视角度,通常可达到170°。MVA是较早投入应用的广视角液晶面板,由日本富士通公司开发,目前生产MVA的厂家有奇美电子和友达光电等。它是利用突出物使液晶静止时并非传统的直立式,而是偏向某一个角度静止;当施加电压让液晶分子改变成水平以让背光通过则更为快速,这样便可以大幅度缩短显示时间,也因为突出物改变液晶20ms以内。分子配向,让视野角度更为宽广。在视角的增加上可达160度以上,反应时间短。2023-07-07 10:59:091

液晶显示屏,硬屏和软屏的区别是什么?
想必大家都听过液晶显示屏又分为硬屏和软屏,但是并不了解硬屏和软屏的区别,小编觉得是时候给大家科普一下硬屏和软屏的区别究竟是什么!硬屏和软屏的区别硬屏和软屏的区别一、硬盘优缺点。IPS技术(In-PlaneSwitching,平面转换)是日立公司于2001推出的液晶屏技术,俗称“SuperTFT”。此技术最大的特点是它的两极都在同一个面上,而不像其它液晶模式的电极是在上下两面,立体排列。由于电极在同一平面上,不管在何种状态下液晶分子始终都与屏幕平行,会使开口率降低,减少透光率,因此IPS应用在液晶电视上会需要更多的灯管,而在一定程度上,耗电量也会大些。另一个缺点是漏光问题比较严重,黑色纯度不够,对比要比PVA稍差,因此必须依靠光学膜的补偿才能实现更好的黑色。IPS屏的优点是可视角度高、向应速度快,色彩还原准确。和其它类型的屏相比,IPS屏的屏幕较为“硬”,用手轻轻划一下不容易出现水纹样变形,因此又有硬屏之称。硬屏和软屏的区别二、软屏优缺点富士通的MVA技术(Multi-domainVerticalAlignment,多象限垂直配向技术)可以说是最早出现的广视角液晶屏技术。该类屏可以提供更大的可视角度,通常可达到170°。改良后的P-MVA类屏可视角度可达178°,已接近目前消费者在家中观看的需求,向应时间亦可达到8ms以下。三星Samsung电子的PVA技术(PatternedVerticalAlignment)同样属于VA技术的范畴,它是MVA技术的继承者和发展者,改良型的S-PVA已经可以和P-MVA并驾齐驱。PVA采用透明的ITO电极代替MVA中的液晶层凸起物,透明电极可以获得更好的开口率,最大限度减少背光源的浪费。VA广视角技术,由于其强大的产能和稳定的质量控制体系,广泛应用于中高端液晶显示器或者液晶电视中。VA类屏属于软屏,用手轻轻划会出现类似的水纹。硬屏和软屏的区别三、结构所谓硬屏产品,就是在液晶屏面上加了一层硬度较高的透明树脂材料保护外膜的产品。硬屏工艺最初由日立等日系厂商所推广,后来LG将该技术进行了大幅的改良,从而形成了非常有特色的S-IPS硬屏工艺技术。硬屏的突出特点是屏幕具有一定的稳定性,用手指轻轻摁下去,不会出现明显的暗影,有利于屏幕保护,但粘贴工艺必须足够好。硬屏主要代表厂商是LG-飞利浦,LG、东芝、日立等厂商的液晶电视大多采用硬屏。这种硬屏液晶电视采用了一种叫做IPS的硬屏技术,由于拥有稳固的液晶分子排列结构,不仅可以完全消除液晶显示屏在受到外界压力时出现的模糊及水纹扩散现象,而且画质更加细腻,可视角度几乎达到180度,在显示动态画面时,对色彩稳定性和层次感的提升也大大提高,而且能保证图像显示的清晰度,更加适合观看比赛节目等动态画面。据了解,在科技含量较高的专业领域如航天、医疗、设计、传播等行业,都会使用色彩还原性更好的硬屏液晶。而且在北京地铁5号线等公共场所也采用了更可靠的硬屏液晶,毕竟,软屏液晶轻轻一碰就出现水纹的屏幕,实在让人觉得缺乏安全感。目前,像LG、松下、飞利浦、创维等许多品牌都早已把这种硬屏配备在主流产品上了。除了屏幕安全系数上的提升之外,硬屏作为液晶技术的革新,相比于传统软屏液晶的优势也绝不仅限于此。首先,硬屏液晶电视具有非常好的可视角度。与软屏液晶相比,由于硬屏通过独有的液晶分子水平转换技术,基本上解决了多年以来传统液晶电视在可视角度方面的痼疾。其次,与传统液晶电视相比,硬屏响应速度更快,呈现的运动画面也更为流畅。而传统的软屏会因为“运动模糊效应”发生大规模图像失真现象以及颜色变化。再者,硬屏液晶电视具有非常高的对比度,纯黑层次更清晰。硬屏液晶在各个灰阶中的白平衡变化完全可以忽略不计。通俗一点说,硬屏液晶电视所显示的画面比软屏的层次感更为清晰,画面表现更为生动。所谓的软屏是相对硬屏而言的,也就是没有采用保护外膜材料的液晶面板。TN、PVA、MVA等面板属于软屏,主要代表厂商是三星。这类液晶屏突出的特点是用手指轻摁或用指甲轻划下去,会出现较为明显的水波纹现象,但过一会儿就消失了。也许是三星S-LCD一类的液晶屏幕容易被摁出“水波纹”的缘故吧,因此称之为“软屏”。不要看重软硬之分。通过上文,大家可以发现硬屏和软屏的根本区别只在屏面加膜或不加膜,而加膜或不加膜不会也不可能改变液晶面板自身的内在物理性能。2023-07-07 11:00:391
WPF中如何在文本外面加虚线外框
首先来个框:<Grid<BorderHorizontalAlignment="Center"VerticalAlignment="Center"Width="60"Height="30"CornerRadius="5" 第一个想到的就是修改Border的Brush,来看看这样的xaml:<Grid<BorderHorizontalAlignment="Center"VerticalAlignment="Center"Width="60"Height="30"CornerRadius="5" BorderThickness="3"<Border.BorderBrush<LinearGradientBrush SpreadMethod="Repeat"StartPoint="0,5"EndPoint="5,0"MappingMode ="Absolute"<LinearGradientBrush.GradientStops<GradientStopColor="Blue"Offset="0"/<GradientStopColor="Blue"Offset="0.2"/<GradientStopColor="Transparent"Offset="0.4"/<GradientStopColor="Transparent"Offset="0.6"/<GradientStopColor="Blue"Offset="0.8"/<GradientStopColor="Blue"Offset="1"/</LinearGradientBrush.GradientStops</LinearGradientBrush</Border.BorderBrush<TextBlockText="aaa"HorizontalAlignment="Center"VerticalAlignment="Center"/</Border</Grid 看看效果图: 再换个思路,更换为使用DrawingBrush:<Grid<BorderHorizontalAlignment="Center"VerticalAlignment="Center"Width="60"Height="30"CornerRadius="5" BorderThickness="3"<Border.BorderBrush<DrawingBrush<DrawingBrush.Drawing<GeometryDrawing<GeometryDrawing.Pen<PenBrush="Blue"Thickness="3"<Pen.DashStyle<DashStyleDashes="3,2,0,2"/</Pen.DashStyle</Pen</GeometryDrawing.Pen<GeometryDrawing.Geometry<RectangleGeometryRect="0,0,60,30"RadiusX="3"RadiusY="3"/</GeometryDrawing.Geometry</GeometryDrawing</DrawingBrush.Drawing</DrawingBrush</Border.BorderBrush<TextBlockText="aaa"HorizontalAlignment="Center"VerticalAlignment="Center"/</Border</Grid 看看效果图: 利用Pen的DashStyle可以轻易的实现点划的虚线图,当然也可以轻易实现点点划的虚线,DashStyle的规则为:实线长度,空线长度,实线长度,空线长度u2026,而实现长度如果为0,就代表点。 不过细看这张图的话,还是会发现一些不和谐的东西,圆角从外侧看,确实是圆的,但是仔细看内侧的话,发现其内侧竟然是个直角。。。 好吧,换个思路,放弃Border了,直接用Canvas,加Rectange:<Grid<GridHorizontalAlignment="Center"VerticalAlignment="Center"Width="60"Height="30"<Canvas<RectangleRadiusX="5"RadiusY="5"Width="60"Height="30"Stroke="Blue"StrokeDashArray="5,2,1,2"StrokeThickness="2"/</Canvas<TextBlockText="aaa"HorizontalAlignment="Center"VerticalAlignment="Center"/</Grid</Grid 看看效果图: 看起来还不错,确实是圆角的,不过这后面两个方案也有个明显的缺点,就是无法随着文本框内容的增长而动态的绘制。当然可以用Binding来进一步消除这个问题:<Grid<GridHorizontalAlignment="Center"VerticalAlignment="Center"Width="60"Height="30"x:Name="g"<Canvas<RectangleRadiusX="5"RadiusY="5"Width="{BindingElementName=g, Path=Width}"Height="{BindingElementName=g, Path=Height}"Stroke="Blue"StrokeDashArray="5,2,1,2"StrokeThickness="2"/</Canvas<TextBlockText="aaa"HorizontalAlignment="Center"VerticalAlignment="Center"/</Grid</Grid效果图: 看起来还不错,不过这个方案还是存在问题的,如果容器Grid本身是自增长的,那么杯具就开始了:<Grid<GridHorizontalAlignment="Center"VerticalAlignment="Center"x:Name="g"<Canvas<RectangleRadiusX="5"RadiusY="5"Width="{BindingElementName=g, Path=Width}"Height="{BindingElementName=g, Path=Height}"Stroke="Blue"StrokeDashArray="5,2,1,2"StrokeThickness="2"/</Canvas<TextBlockText="aaa"HorizontalAlignment="Center"VerticalAlignment="Center"/</Grid</Grid效果图:可以发现,Grid使用了自增长的方式,Binding也只能获得错误的Width和Height,也就是0,不过别担心,WPF还提供了ActualWidth和ActualHeight:<Grid<GridHorizontalAlignment="Center"VerticalAlignment="Center"x:Name="g"<Canvas<RectangleRadiusX="5"RadiusY="5"Width="{BindingElementName=g, Path=ActualHeight}"Stroke="Blue"StrokeDashArray="5,2,1,2"StrokeThickness="2"/</Canvas<TextBlockMargin="10,7,10,7"Text="aaa"HorizontalAlignment="Center"VerticalAlignment="Center"/</Grid</Grid效果图:哈哈,圆满达成目标。2023-07-07 11:00:471

硬屏与软屏的简单区分 IPS (硬屏) IPS技术(In-Plane Switching,平面转换)是日立公司于2001推出的液晶屏技术,俗称“Super TFT”。IPS阵营以日立为首,聚拢了LGD、瀚宇彩晶等厂商。 此技术最大的特点是它的两极都在同一个面上,而不像其它液晶模式的电极是在上下两面,立体排列。由于电极在同一平面上,不管在何种状态下液晶分子始终都与屏幕平行,会使开口率降低,减少透光率,因此IPS应用在液晶电视上会需要更多的灯管,而在一定程度上,耗电量也会大些。 另一个缺点是漏光问题比较严重,黑色纯度不够,对比要比PVA稍差,因此必须依靠光学膜的补偿才能实现更好的黑色。 IPS屏的优点是可视角度高、向应速度快,色彩还原准确。和其它类型的屏相比,IPS屏的屏幕较为“硬”,用手轻轻划一下不容易出现水纹样变形,因此又有硬屏之称。 VA (软屏) 富士通的MVA技术(Multi-domain Vertical Alignment,多象限垂直配向技术) 可以说是最早出现的广视角液晶屏技术。该类屏可以提供更大的可视角度,通常可达到170°。改良后的P-MVA类屏可视角度可达178°,已接近目前消费者在家中观看的需求,向应时间亦可达到8ms以下。 三星Samsung电子的PVA技术(Patterned Vertical Alignment)同样属于VA技术的范畴,它是MVA技术的继承者和发展者,改良型的S-PVA已经可以和P-MVA并驾齐驱。PVA采用透明的ITO电极代替MVA中的液晶层凸起物,透明电极可以获得更好的开口率,最大限度减少背光源的浪费。 VA广视角技术,由于其强大的产能和稳定的质量控制体系,广泛应用于中高端液晶显示器或者液晶电视中。VA类屏属于软屏,用手轻轻划会出现类似的水纹。 屏幕的软硬,非选购取舍的唯一标准 目前,采用VA广视角技术的屏厂商有友达光电(AUO)、奇美电子(CMO)、中华映管(CPT)、三星及夏普;采用IPS技术的有IPS Alpha与LGD。 在同一场合,使用同一信号源,对比观看两款不同的液晶电视,如果画质有明显的差别,那么关键的问题应在液晶屏的等级与核心驱动的性能,而不在屏幕的软硬。因此,硬屏和软屏的合理解释,只在厂家的生产工艺特色,尽管各有不同,但也是万变不离其宗。 硬屏和软屏的物理性能都是一样的,只要不用重力撞击或用尖锐器物刻划,都不容易损伤。家电行业的专家认为,无论是硬屏还是软屏,都不可能决定液晶电视产品品质,也不应成为消费者选购取舍的唯一标准。 硬屏与软屏虽然在制作工艺上有一定的区别,但在性能上并没有绝对的优劣之分。前者漏光对比差,后者侧看色彩失真,然而硬屏与软屏厂商都已朝各自缺点逐步完善,世事无绝对,硬屏好、软屏差的谬论在信息流通的现代自然是不攻自破。硬屏透光性能与软屏在质量上没有明显区别,硬屏外加的保护膜不会造成透光不好,膜和屏幕粘合工艺要求也相当精良。而没有加保护外膜的软屏,只要消费者在使用时注意,不用重力撞击或用尖锐器物刻划,一般也不容易划伤2023-07-07 11:02:364

wp /wpf 中 我想实现scrollviewer里面横向有三个控件,怎样实现滚动,下面也都是这个形式
ScrollViewer 给Width值指定一下,然后里边的内容的宽度也设置一下,当里边的宽度超过外边的宽度滚轮就有了,还有就是ScrollViewer里边VerticalScrollBarVisibility HorizontalScrollBarVisibility这两个属性设置一下,是横向和纵向滚轮显示的问题2023-07-07 11:02:511
