Program writing method for TCON drive IC

Abstract

The invention discloses a program writing method for a TCON drive IC. The method comprises steps that in main software of an SOC machine core mainboard, TCON drive IC program partitions are divided, different liquid crystal screen model directories are arranged under the partitions, a specific drive IC program is contained under each directory, and the drive IC programs are matched with the liquidcrystal screen models of the directories to which the drive IC programs belong; writing commands and writing addresses for different types of TCON drive ICs are stored in a writing command database of SOC core mainboard main software, and the writing commands and the writing addresses are distinguished by command serial numbers; a program writing command option is added in a liquid crystal screenparameter ini file of main software of the SOC core mainboard; before the SOC core mainboard is powered on, a currently matched liquid crystal screen model is inputted into the core memory; and afterthe SOC core mainboard is powered on, the writing controller performs writing operation by calling a liquid crystal screen parameter ini file matched with the current liquid crystal screen model anda TCON drive IC program. According to the method, material and management and control cost of the TCON drive IC writing process is reduced, and the service life of the TCON drive IC is guaranteed.

Description

technical field [0001] The invention relates to the technical field of liquid crystal televisions, in particular to a programming method for a TCON driver IC. Background technique [0002] In the LCD TV industry, with the full application of TCONless technology, more and more TCON boards have been self-developed and produced by TV OEMs. The dedicated ICs on the TCON board generally include PMIC, PGAMMA, and Levelshifter, etc. These dedicated ICs are generally referred to as TCON driver ICs. During the production of TCON boards, the TCON driver IC needs to be written into the program. At present, the common programming method is programming with the programming tool. This method has the following problems: [0003] (1) The cost of programming tools is relatively high. Different types of driver ICs have different packages, PIN pin definitions, and programming commands. The programming tool must match the driver IC model, and because the parts that fix the IC are prone to ag...

Problems solved by technology

As a result, it is necessary to prepare more types and quantities of burning tools, which increases management and equipment costs

[0004] (2) Program maintenance is more difficult

[0005] For the TCONLESS method currently widely used in the complete set factory, the TCON board and the core board are manufactured and controlled by the TV complete set factory, and there are also some methods that use the SOC main software to program the TCON driver IC, but they cannot solve the problem of matching. Different TCON driver ICs and different LCD screens, programming commands and driver IC programs are not compatible, resulting in difficulties in the management of the SOC main software
