【摘要】：为了提高夜视兼容的液晶显示器(LCD)显示屏的显示效果,在使用红绿蓝三色LED为背光源的基础上,增加了红外LED,将不同的LED搭配成在不同模式下使用的两套光源。根据10.4in(1in=2.54cm)背光源的亮度和均匀性的要求,将背光源当作朗伯发光体来计算亮度,以便于选择LED的类型,确定LED的数量和排列方式,合理选择光学膜片及设计背光模组的结构。由于红外LED的发光功率可调节,在夜视兼容模式下,不仅可以通过夜视仪看清LCD显示屏上的信息,而且用裸眼也可以轻易看清显示屏上的信息。通过TracePro软件进行仿真并分析,结果发现设计的背光模组同时满足了LCD显示屏的强光下可视和夜视兼容两项要求。
[Abstract]:In order to improve the display effect of night vision compatible liquid crystal display (LCD) display, infrared LED is added on the basis of red, green and blue LED as backlight source. The different LED is collocated into two sets of light sources used in different modes. According to the requirements of brightness and uniformity of the backlight, 10.4in ~ (1) inn ~ (2. 54 cm). The backlight source is used as a Lambert luminous body to calculate the brightness so as to select the type of the LED and determine the number and arrangement of the LED. Due to the adjustable luminous power of infrared LED, not only the information on LCD display can be seen through night-vision device but also in the compatible mode of night-vision. And the naked eye can also easily see the information on the display screen. Through the TracePro software simulation and analysis. The results show that the designed backlight module can meet the two requirements of visual and night vision compatibility of LCD display screen.
