Abstract

The invention provides a display panel driving system. The system comprises a memory, a time sequence control chip and a panel driving chip. The memory is used for storing drive data. The time sequence control chip is used for downloading driving data from the memory in a startup stage and sending the data to the panel driving chip. The panel driving chip comprises a main chip body and a register,and the main chip body is used for receiving the driving data in a startup stage, writing the driving data into the register and driving the display panel to work according to the driving data stored in the register in a display stage. Based on the system, a special memory does not need to be configured for the panel driving chip, so that a plurality of chips can share one memory, the technicalproblem that the memory needs to be set for the panel driving chip in the current display panel driving system is solved, and the cost is reduced.

Description

technical field [0001] The invention relates to the display field, in particular to a display panel drive system. Background technique [0002] The display panel drive system includes panel drive chips such as gamma chip (P-gamma IC), power management chip (Power manageIC, PMIC), etc. These panel drive chips have internal memory to store relevant data, such as the memory in the gamma chip The gamma data is stored, the memory in the power management chip stores the voltage data, and these panel driver chips drive the display panel according to the internally stored driving data. [0003] That is, the panel driver chip in the current display panel driver system has the technical problem that memory needs to be set. Contents of the invention [0004] The present invention provides a display panel drive system to solve the technical problem that a memory needs to be set in the panel drive chip in the current display panel drive system. [0005] In order to solve the above pr...
