1 日本岩崎电气公司开发中心,新开发出的投影液晶显示,工作5000 h 后,亮度才下降到始值的1/2,初始亮度达到原先的2.5～3.3倍。这是由于背光源的透过率高,光利用率上升之故。2 新开发出来的 LCD 板封接树脂,在常温下,用紫外线照20～30 s,就可固化。这样短的固化时间,对液晶分子取向无影响。原来的紫外固化树脂,紫外线照射时间,需1～2 h,会影响液晶分子取向。
1 Japan Iwasaki Electric Development Center, the newly developed projection LCD display, working 5000 h, the brightness fell to the original value of 1/2, the initial brightness of 2.5 to 3.3 times the original. This is due to the high transmittance of the backlight and the increase of the light utilization rate. 2 newly developed LCD board sealing resin, at room temperature, with UV 20 to 30 s, can be cured. Such a short curing time has no effect on the alignment of liquid crystal molecules. The original UV curing resin, UV irradiation time, take 1 ~ 2 h, will affect the liquid crystal molecular orientation.
