制作了分辨率为128×160的1.9"全彩无源有机发光二极管(OLED)屏,OLED全彩像素的尺寸为240μm×240μm,子像素尺寸为190μm×45μm。显示系统通过数字显示接口(DVI)可将微机输出的18bits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,器件的功耗为300mW。
A full-color OLED panel with a resolution of 128 × 160 was fabricated. The OLED full-color pixel has a size of 240μm × 240μm and a sub-pixel size of 190μm × 45μm. The display system is connected to the display through the digital display interface DVI) can be computer output 18bits grayscale data sent to the drive circuit, so as to achieve 262k colors.When the screen average working brightness of 40cd / m2, due to the dual-screen drive technology, OLED screen life expectancy of more than 5000h, The device consumes 300mW.
