摘要
采用平面结构式OLED实现彩色,制作了分辨力为128×160的1.9″全彩无源OLED屏,OLED全彩像素的尺寸为240μm×240μm,子像素尺寸为190μm×45μm。显示系统通过DVI接口可将微机输出的18位灰度数据传送到驱动电路,从而实现262k种颜色。当屏的平均工作亮度为40cd/m2时,由于采用了双屏驱动技术,OLED屏的寿命预计超过5000h,器件的功耗约为300mW。
By using the plane structured Organic Light-emitting Diodes （OLED） realize color, a full color 1.9″ passive-matrix OLED has been developed. The display has 128 （3） 160 pixels with an equivalent full color pixel size of 240 μm？240 μm, and the size of mono sub-pixel is 190 μm45 μm. 18 bits gray-scale data was transferred from a PC by a Digital Visual Interface （DVI） interface. Then, the driving circuits realize 262 k color mode display. The dual-scan driving technology was used to prolong the lifetime of the OLED display to 5 000 h at the average luminance of 40 cd/m2, and the power consumption of the display was about 300 mW.
