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240 μm×240 μm，子像素尺寸为190 μm×45 μm。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262 k 种颜色。当屏的平均工作亮度为40 cd/m2 时，由于采用了双屏驱动技术，OLED屏的寿命预计超过5 000 h，器件的功耗约为300 mW。

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 μm×45 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.
