Title:
VOLTAGE OUTPUT SYSTEM AND LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/232987
Kind Code:
A1
Abstract:
A voltage output system and a liquid crystal display device. The voltage output system is provided with a variable resistor (50). An input voltage transmitted by a level conversion unit (60) is accessed by one end of the variable resistor (50) by means of a contact (21, 31 and 23) and a wire (41 and 43), and the other end of the variable resistor (50) is electrically connected to a liquid crystal panel (1) by means of a contact (22, 32 and 24) and a wire (42 and 44) so as to output an output voltage. After the voltage output system is disposed on an assembly circuit board (3) of the liquid crystal display device, it is possible to make the output voltage of the voltage output system a preset required voltage by means of adjusting the resistance of the variable resistor (50) during the testing of the liquid crystal display device. The system may conveniently and quickly provide output voltages having different voltage values for the liquid crystal panel (1), thereby effectively simplifying the testing operations for the liquid crystal display device and reducing the product cost.
