(3)5bit(32步级)程控取样像素时钟相位(0°～360°),实现取样时钟相位准确校正(比较RGB像素时钟边沿和HSYNC边沿的差异进行调整)。(4)内置定时器控制的钳位脉冲产生电路,钳位脉冲起始、维持时间均受程序控制。钳位时间不足,充电电流低,导致画面亮度不均匀。(5)数字亮度、对比度控制。(6)精确参考电压形成电路。
(3) 5bit (32 steps) program sampling pixel clock phase (0 ° ~ 360 °), to achieve accurate sampling phase correction (compare RGB pixel clock edge and HSYNC edge to adjust the difference). (4) Built-in timer control clamp pulse generating circuit, clamp pulse start and hold time are subject to program control. Insufficient clamping time, low charging current, resulting in uneven brightness of the screen. (5) digital brightness, contrast control. (6) accurate reference voltage forming circuit.
