• 如何使LCD屏在阳光下可视

  随着科技的发展进步，LCD液晶显示屏应用的场所越来越多，而LCD液晶显示屏在我们身边又**着很重要的位置，但是现在很多LCD液晶显示屏在阳光下不可视，室外环境使用非常不方便，不过我们已经有了在阳光下的可视方案。今天小编就带大家来了解一下这种方案吧。我们应该都有这样的困扰，在户外阳光强烈的情况下，手机的可视程度几乎为0，由于屏幕显示的画面的亮度低于反射光的亮度，反射光是白色的，更亮，淹没了黑色和其他

• 清达光电OLED使用注意事项

  杭州清达光电/杭州佳显科技从事OLED显示模块生产销售十多年，批量出货电力、环保、**、医疗等行业客户，在杭州设有工厂，各种老化试验设备，欢迎来电咨询选购。下面介绍下使用OLED显示模块时的注意事项：OLED 模块的功耗 OLED 是主动发光的，只有点亮的像素才需要消耗电，像素点点亮越多，像素点亮度越 高，功耗会越大（过高的亮度也会影响寿命）。 因此，为了降低功耗，客户在成品设计时： ☆ 避免把亮

• 工业液晶屏反应迟钝怎么办？

  工业液晶屏在使用过程中，会出现一些故障，如不敏感的现象，那是什么原因会导致这种现象发生呢?让我们学习一下如何更好地做好工业液晶屏的维护措施。如果触摸屏反应缓慢，可能是触摸屏系统陈旧，内部时钟频率太低，或者由于触摸屏表面有水滴而无法移动，为了使触摸屏恢复到快速响应，必须重新更换或升级系统，或者用抹布擦拭触摸屏表面。一般来说，这种现象对于多数触摸屏来说是很常见的，但是应该注意维护它们。在详细的操作使用
