Abstract
The invention relates to the technical field of liquid crystal television, and discloses an automatic program writing method for a TCON chip. The problems that in the traditional technology, manual and special programmers are needed for program writing operation in the program writing method, so that the production cost is high, and efficiency is low are solved. The method comprises the following steps that 1, when TCON board is designed in an integrated mode for a liquid crystal television mainboard, and an IIC bus of a mainboard SOC chip and IIC buses of a PMIC and a PGAMMA IC are connected; the function that programs are written for the PMIC and the PGAMMA IC successively after the first time of startup is added in mainboard software; c, PMIC and PGAMMA IC empty chips are mounted; d, when a liquid crystal television set is started for the first time, the mainboard software automatically and successively writes programs into the PMIC and the PGAMMA IC, and therefore chips can normally work.
Description
Technical field
The present invention relates to liquid crystal tv technology field, be specifically related to LCD TV TCON chip writes Cheng Fangfa.
Background technology
The TCON plate of LCD TV is a critical function module of liquid crystal display screen, and the Main Function of TCON plate is the row to liquid crystal display screen
Field scanning signal carries out strict sequencing contro, produce the various voltages of liquid crystal display screen work and liquid crystal television mainboard end is sent here upper
Screen signal carries out process etc..
Two important chip: PMIC (power management integrated circuit chip) and PGAMMA IC (gal able to programme is had on TCON plate
Agate correction buffer circuit chip).The effect of PMIC be produce liquid crystal display screen work required for various voltages, as AVDD, DVDD,
The voltages such as VGH, VGL；PGAMMA IC produces liquid crystal display screen GAMMA reference voltage and VCOM voltage.
In LCD TV TCON plate, PMIC and PGAMMA IC normally to work, it is necessary first to write-in program in this two chips.
Conventional art write Cheng Fangfa as it is shown in figure 1, it uses cd-rom recorder write-in program in PMIC and PGAMMA IC respectively, then
Carry out mounting upper part by the chip finishing writing program again.This Cheng Fangfa of writing needs artificial and special cd-rom recorder to carry out writing journey operation,
Shortcoming is that production cost is higher, inefficient.
TCON plate is usually and is developed by liquid crystal display screen producer and produced, along with the development of LCD TV industry, in order to reduce LCD TV
Complete machine cost, the TCON plate of LCD TV starts to carry out Integration Design, i.e. TV motherboard with mainboard and completes TCON plate function
Design.
Summary of the invention
The technical problem to be solved is: propose a kind of method that TCON chip writes journey automatically, solves to write in conventional art
Cheng Fangfa needs artificial and special cd-rom recorder to carry out writing journey operation, and the production cost brought is higher, inefficient problem.
The technical solution adopted for the present invention to solve the technical problems is: a kind of method that TCON chip writes journey automatically, including following
Step:
A. when liquid crystal television mainboard Integration Design TCON plate, by iic bus and PMIC and the PGAMMA IC of mainboard SOC
Iic bus link together；
B. in mainboard software, increase the function writing journey after first powering on first to PMIC and PGAMMA IC；
C. the empty sheet of PMIC and PGAMMA IC is mounted upper part；
D., when LCD TV first powers on, mainboard software is successively from PMIC and PGAMMA IC two chips of trend TCON
Write-in program, so that chip normally works.
As optimizing further, in step d, mainboard software is successively from PMIC and the PGAMMA IC two of trend TCON
The method of chip write-in program is:
When TV first powers on, mainboard inputs 12V supply voltage to PMIC, and mainboard software automatically writes program to PMIC, so
After by PMIC to PGAMMA IC input 3.3V supply voltage, mainboard software automatically writes program to PGAMMA IC again.
As optimizing further, described mainboard software passes through iic bus successively from PMIC and the PGAMMA IC of trend TCON
Two chips write-in programs.
The invention has the beneficial effects as follows:
It is no longer necessary to, with cd-rom recorder, chip is write journey on producing, reduces production cost, improve production efficiency.
Accompanying drawing explanation
Fig. 1 is the flow chart writing journey in conventional art to PMIC and PGAMMA IC chip；
Fig. 2 is the flow chart writing journey in the present invention to PMIC and PGAMMA IC chip.
Detailed description of the invention
For solving PMIC and PGAMMA IC conventional write journey method cost problem high, inefficient.The present invention is at liquid crystal television mainboard
During Integration Design TCON plate, by total to the iic bus of mainboard SOC and the IIC of PMIC and PGAMMA IC in circuit design
Line links together.When TV first powers on, mainboard inputs 12V supply voltage to PMIC, and first mainboard software is write to PMIC
Entering program, then PMIC inputs 3.3V supply voltage to PGAMMA IC, and last mainboard software is write in trend PGAMMA IC
Enter program.So it is no longer necessary to, with cd-rom recorder, chip is write journey on producing, reduces production cost, improve production efficiency.
As in figure 2 it is shown, the method that TCON chip of the present invention writes journey automatically includes implemented below step:
1, liquid crystal television mainboard end Integration Design liquid crystal display screen TCON plate, the iic bus of mainboard SOC and TCON plate PMIC
Link together with the iic bus of PGAMMA IC；
2, the function of journey is write after increase first powers on first in mainboard software to PMIC and PGAMMA IC；
3, the upper part of PMIC and PGAMMA IC sky sheet attachment；
4, when TV first powers on, mainboard is powered 12V to PMIC, and mainboard software automatically writes program in PMIC；
5, PMIC inputs 3.3V supply voltage to PGAMMA IC, and mainboard software automatically writes program again in PGAMMA IC.
Described mainboard software passes through iic bus successively from trend PMIC and PGAMMA IC two chips write-in program.
