笔记本的液晶显示屏看二四六开奖结果由两块玻璃板构成,厚约1毫米,中间是厚约5微米(1/1000毫米)的水晶液滴,被均匀间隔隔开,包含在细小的单元格结构中,每三个单元格构成屏幕上的一个像素。在放大镜下呈现方格状,一个像素即为一个光点。每个光点都有独立的晶体管来控制其电流的强弱,如果该点的晶体管坏掉,就会造成该光点永远点亮或不亮,这就是前面提到的亮点或暗点,统称为”坏点”。

“坏点”真的不可避免吗?随着竞争加剧和技术工艺水平提高,液晶屏的生产厂家提高了原料标准,加强了生产和检验等内部质量控制,大大减少了其出现的频率。检查坏点的方法相当简单,只要将液晶屏看二四六开奖结果的亮度及对比度调到最大(显示反白的画面)或调成最小(显示全黑的画面),你可能会发现,屏幕上有不少亮点或暗点存在。液晶显示器厂商一般对此的解释是只要坏点的数量和分布没有超出一定的标准,出现一个或者多个坏点的液晶显示器是正常的,是符合行业标准的。当然了,关于坏点的测试,还有的朋友用软件测试,就显得稍微专业一点了,则更可以让坏点”无处藏身”!
