图7所示是原文中绘制的集成电路TPS65161的VGH和VGL电压产生电路原理图。(2)VGL电压的产生电路(见图8)图8所示电路中,黑框线内部是VGL电压的产生部分电路,按液晶屏的要求,VGL电压为-5～-6V左右。在粗黑框线内部的元器件CP22、DP8(1)、DP8(2)、CP24等组成了一个“负压半波整流电路”。TPS65161(11)脚输出幅度为5V左右的方波开关信号,加到“负压半波整
Figure 7 shows the original drawing of the integrated circuit TPS65161 VGH and VGL voltage generating circuit diagram. (2) VGL voltage generating circuit (see FIG. 8) In the circuit shown in FIG. 8, the inside of the black frame is a part of the circuit for generating the VGL voltage. According to the requirements of the liquid crystal panel, the VGL voltage is about -5 to -6V. The components inside the thick black frame of CP22, DP8 (1), DP8 (2), CP24, etc. constitute a ”negative pressure half-wave rectifier “. TPS65161 (11) pin output amplitude of about 5V square wave switching signal, added to the ”negative pressure half-wave
