Problems solved by technology

However, the problem that is more likely to occur now is that due to wire or other interference during the production process, the WP will also be invalidated, and the I2C protocol communication is not normal, then there may be malfunctions that cause the TCON stored in the EEPROM to The code is rewritten, and there is no error correction mechanism today, so it is impossible to prevent this situation, which will cause abnormal display screens and frequent errors

Abstract

The invention discloses a method and a system for protecting software data in a display panel. The method comprises the following steps that: providing a display panel and a storage unit, wherein the storage unit is arranged on a driving board on the display panel for storing one piece of write protection information and the software data of a time sequence control unit; through one information detection unit in the time sequence control unit, the state of write protection information is detected; and when the state of the write protection information is a write protection failure state, one MCU (Microprogrammed Control Unit) micro-processing unit in the time sequence control unit refuses to read the software data of the time sequence control unit. Therefore, the software data on the storage unit can be prevented from being rewritten so as to avoid a situation that a picture displayed on the display panel is abnormal.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method and system for protecting software data in a display panel. Background technique [0002] A liquid crystal display is one of the most widely used flat panel displays, and includes two substrates having pixel electrodes, common electrodes, etc., and a liquid crystal layer interposed between the two substrates. The liquid crystal display displays images by determining orientations of liquid crystal molecules of a liquid crystal layer and controlling polarization of incident light by an electric field generated by voltages applied to electrodes. Liquid crystal displays are advantageous for displaying moving images and have high contrast, thus replacing existing cathode ray tubes, and are variously used as display devices of mobile terminals (notebook monitors, etc.), computer monitors, televisions, and the like. [0003] On the driver board of the LCD panel, there is a pr...
