Method for upgrading time schedule controller, and display control device and display device thereof

Abstract

The invention discloses a method for upgrading a time schedule controller, and a display control device and a display device thereof. The method comprises steps of receiving an upgrading instruction sent b a micro controller, wherein the micro controller is coupled with one end of the time schedule controller through a first connection bus and a second connection bus; through the first connectionbus, receiving data sent by the micro controller, wherein the data is used for upgrading firmware of the time schedule controller; and through the second connection bus, sending an upgrade success instruction to the micro controller through the second connection bus, and backing up the data to a backup memory of the micro controller through the second connection bus. According to the invention, additional data lines are not increased, data safety is improved and technology support is provided for data abnormity of the time schedule controller.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for upgrading a timing controller, a display control device, and a display device. Background technique [0002] With the development of display technology, people have higher and higher requirements for displayed images, especially color images. A liquid crystal display (LCD) is widely used due to its characteristics of small size, low power consumption, relatively low manufacturing cost, and no radiation. However, due to the constraints of various factors on the display, there will be a certain color shift in the color image displayed on the display. In order to solve this problem, it is necessary to do some algorithm processing through the timing controller to improve the image display quality of the display. [0003] The inventor of the present invention has found in the long-term research and development that at present, to update the data of the timing controller...

Problems solved by technology

However, due to the constraints of various factors on the display, there will be a certain color shift in the color image displayed on the display. In order to solve this problem, it is necessary to do some algorithm processing through the timing controller to improve the quality of the image displayed on the display.

[0003] The inventor of the present invention has found in the long-term research and development that at present, to update the data of the timing controller, it is necessary to communicate with the micro control unit ((Microcontroller) of the TV manufacturer through the corresponding serial peripheral interface (Serial Peripheral Interface, SPI) and I2C signal line. Unit, MCU) are connected together, and it is not easy to realize the confidentiality of data while adding data lines. At the same time, when the memory chip of the timing controller is abnormal, it will cause abnormal display on the LCD panel
