Abstract

The invention provides a display device drive system and method. The system comprises a main time sequence controller, at least one slave time sequence controller connected with the main time sequencecontroller, and a first flash memory chip connected with the main time sequence controller. The first flash memory chip is used for storing a configuration code of the main time sequence controller and configuration codes of the slave time sequence controllers. During operation, the main time sequence controller reads the configuration code of the main time sequence controller and configuration codes of the slave time sequence controllers from the first flash memory chip, and transmits the configuration codes of the slave time sequence controllers to the slave time sequence controllers. The slave time sequence controllers receive the configuration codes of the slave time sequence controllers from the main time sequence controller, thereby completing the configuration of the time sequencecontrollers. The system can reduce the number of flash memory chips, improves the utilization rate of the storage space and a circuit board design space, and reduces the waste of resources.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device driving system and method. Background technique [0002] With the development of display technology, liquid crystal displays (Liquid Crystal Display, LCD) and other flat display devices are widely used in mobile phones, televisions, personal Various consumer electronic products such as digital assistants, digital cameras, notebook computers, and desktop computers have become the mainstream of display devices. [0003] A flat panel display device generally includes a display panel (Panel) and an external driving circuit, and the external driving circuit generally includes: a timing control chip (TCON), a power management chip (Power manage IC) and programmable gamma correction chip (P-gamma IC), etc., wherein the timing control chip is mainly used to convert low-voltage differential signaling (Low-Voltage Differential Signaling, LVDS) signals into low-am...
