LCD electrostatic protection method and LCD

Abstract

The invention provides an LCD electrostatic protection method, relating to the technical field of electronics, comprising the following steps: refreshing the LCD working parameters stored in a register, which changes the stored data under the influence of static electricity; and conducting data calling and displaying work by the LCD according to the refreshed working parameters. The embodiment of the invention also provides an LCD. In the embodiment of the invention, before the LCD conducts the task of calling display data for each time, the LCD working parameters stored in the register are refreshed, thus avoiding the influence of instant high-voltage pulse caused by electrostatic charge on the LCD working parameters, ensuring the accuracy of LCD data calling and displaying, namely, ensuring the normal operation of the LCD.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a liquid crystal display (LCD, Liquid Crystal Display) electrostatic protection method and the LCD. Background technique [0002] At present, as the use of metal materials for terminal structures becomes more and more popular, it brings great challenges to the electrostatic discharge (ESD, Electrostatic Discharge) protection capability of LCDs. [0003] Since the data transmission and control of the LCD are mainly coordinated by an internal integrated processing chip (IC, Integrated Circuit), the data in the peripheral registers is stored by a random access memory (RAM, Random Access Memory) inside the IC. [0004] In the process of realizing the present invention, the inventor found that the prior art has at least the following shortcomings: the influence and interference of ESD on the LCD is that the instantaneous high-voltage pulse is transmitted through the signal line, a...

Problems solved by technology

[0004] In the process of realizing the present invention, the inventor finds that the prior art has at least the following shortcoming: the impact and interference of ESD on LCD is to transmit the instantaneous high voltage pulse through the signal line, and the data stored in the register connected with the external signal, namely The stored LCD working parameters are disrupted. Since the data stored in the register is maintained by electric charges, once it is impacted by an external high voltage, it is easy to cause changes.

Therefore, if the data stored in these registers is wrong, the transmitted data will be wrong, which will cause the LCD to work abnormally.
