Abstract

The present invention discloses a liquid crystal display module, comprising a liquid crystal display panel, a driving chip pressed in the liquid crystal display panel and a flexible circuit board in electrical connection with the driving chip, wherein, the driving chip comprises an interface circuit and an analog / digital conversion circuit in electrical connection with the interface circuit; the flexible circuit board transmits an analog voltage signal to the analog / digital conversion circuit of the driving chip; the analog / digital conversion circuit receives the analog voltage signal and converts the analog voltage signal into a multi-bit digital signal which is then output to the interface circuit; the interface circuit determines the interface working mode of the driving chip through the multi-bit digital signal. The present invention has good compatibility.

Description

technical field [0001] The invention relates to a liquid crystal display module. Background technique [0002] At present, the liquid crystal display (Liquid Crystal Display, LCD) has gradually replaced the traditional cathode ray tube (Cathode Ray Tube, CRT) display used in calculators, and because the liquid crystal display module is light and thin, it is very suitable for Desktop calculators, personal digital assistants (Personal Digital Assistant, PDA), portable phones, televisions and various office automation and audio-visual equipment. With the continuous maturity of liquid crystal display technology, liquid crystal displays are developing in the direction of diversified functions. [0003] see figure 1 , is a structural schematic diagram of a liquid crystal display module in the prior art. The liquid crystal display module 10 includes a liquid crystal display panel 100 , a driver chip 110 and a flexible circuit board 170 . The driving chip 110 is pressed on the l...
