摘　　要：针对单绿高亮硅基OLED显示屏的特点,研究了其亮度调节电路,以满足高低温、宽范围亮度条件下的应用要求。选取2.4cm单绿高亮硅基OLED作为显示屏组件,设计了具有温度-亮度补偿功能的宽范围亮度调节电路,并优化了调亮曲线,以满足高低温下亮度一致性的应用要求。最后进行了相应的光电测试,验证其有效性。According to the characteristics of green and high brightness OLED-on-silicon display, the brightness adju^stment circuit was studied to meet the application requirements of high and low temperature environments and wide range brightness. The 2. 4 cm green and high bright OLED-on-silicon display was selected as the display module, and a wide range brightness adjustment circuit with temperature- brightness compensation was designed. The brightness curve was optimized to meet the application requirements of brightness consistency at high and low temperature environments. Finally, the photoelectric test was carried out to verify the effectiveness of design.
