Problems solved by technology

This brings huge troubles for after-sales and client update of display software, and it is often necessary to prepare multiple sets of burning equipment
And there are no such professional equipment in the real client
Need professional technicians to come to deal with or ask customers to send defective monitors for repair
This requires a lot of after-sales service costs

Embodiment 1

[0050] Such as figure 2 As shown, a Lenovo Kaitian M3000 PC is used as an end-user PC for burning, the PC is installed with Microsoft Windows XP operating system, and the AOC 2217V+ display is the software update object to illustrate the specific implementation of the present invention. Because the AOC 2217V+ display uses Realtek Scalar IC. Therefore, in this example, the Realtek programming program is used as the FLASH programming program for description.

[0051] The present invention uses the built-in graphics card of the terminal user PC as a burning device, and uses the DDC (digital display channel) port of the graphics card to send software data into the FLASH of the display device through the I2C protocol for software update.

[0052] The method of using the built-in graphics card of the end-user PC as the burning device is: on the end-user PC, install application software, the application software first obtains the position of the built-in graphics card, and finds th...

Abstract

The invention relates to the field of display equipment, in particular to liquid crystal display manufacture and after-sales repair and a display equipment software updating method. Software data is sent to an FLASH of display equipment to update software by using an in-built display card of a terminal user PC (Personal Computer) as burning equipment and using an DDC (Digital Display Channel) port of the display card through an I2C (Inter-Integrated Circuit) protocol. Compared with the prior art, the invention has the advantages that since the in-built display card of the terminal user PC can be used as the burning equipment, a professional after-sales personnel does not need for home repair or an end user for sent repair, and the end user does not need to have professional equipment and professional knowledge. A large number of after-sales repair cost can be saved, and the goals of saving the repair time and saving repair cost of bad products in the market are achieved.

Description

technical field [0001] The invention relates to the field of display devices, in particular to liquid crystal display manufacturing and after-sales maintenance services, and in particular to a display device software update method. Background technique [0002] The most popular display device is a monitor for a PC. The first monitors were CRT monitors. The cathode ray tube used in the display screen, all adjustments are done by hardware without software support. With the development of information technology. The CRT display of the ESC appeared, but at this time it was only the control circuit of some logic gates. In the 1990s, monitors with OSD control interfaces appeared. At this time, the monitors must use the MCU control system. MCU is called single-chip microcomputer for short, it is a kind of microprocessor, it needs software support. The early software was only OSD and screen control. Only a small amount of hardware control is involved, and most of it is still d...
