Title
(EN) Driving circuit, LCD display screen and electronic equipment
(ZH) 驱动电路、LCD显示屏以及电子设备
Abstract
(EN) The invention provides a driving circuit, an LCD display screen and electronic equipment. Each driving unit comprises a driving chip and a chip controller; the signal end of the driving chip and the control end of the chip controller are connected through a control signal line; the intersection part of any two intersected control signal lines is positioned on the driving chip; the rest parts of any two intersected control signal lines are positioned on the conducting layer; therefore, the substrate with the single conductive layer can realize the cross layout of a plurality of control signal lines, the resistance of the substrate is reduced, the amplitude difference of control signals for controlling the driving chips at the two ends is reduced, and the driving chips can act according to preset control signals so as to control the light-emitting units to be turned off according to a preset mode.
(ZH) 本申请提供一种驱动电路、LCD显示屏以及电子设备,每个驱动单元包括驱动芯片和芯片控制器,通过控制信号线连接驱动芯片的信号端和芯片控制器的控制端,并将任意两个相交的控制信号线的相交部分位于驱动芯片上,将任意两个相交的控制信号线的其余部分位于导电层上,使得具有单层导电层的基板即可实现多个控制信号线的交叉布局,减少基板的电阻,使得控制位于两端的驱动芯片的控制信号的幅值差异减少,驱动芯片可以依据预设的控制信号动作,进而按照预设方式控制发光单元熄灭。
