Problems solved by technology

Due to the many and complex scanning modes and input signal formats of the machine, there are different requirements for the debugging signal, and the debugging method is also relatively complicated. A large number of personnel, instruments, and meters must be invested in the production to meet the factory design standards of the machine.
have a certain impact on the production cost of the machine

Embodiment Construction

[0009] This technology is currently used in the 29HD12G model, as follows:

[0010] 1. Make E by the designer before production 2 PROM.

[0011] 2. Debuggers debug key items such as row center, field center, etc.

[0012] 3. Through the data records after debugging, continuously improve the E 2 Correction values ​​in PROM for quicker commissioning. Perfect E 2 The correction value in PROM is to store the latest correction value in E before production 2 in PROM.

[0013] 4. Geometry debugging

[0014] When debugging the geometry, you only need to debug one scan mode such as 60P scan mode, and you can also debug a certain scan mode of 75i and 75p. The adjusted parameters are fixed and automatically stored in the addresses of other scan modes and signal formats by the program.

[0015] Due to the different scanning modes of 60p (progressive), 75i (interlaced), and 75p (progressive), the signal formats of VGA, SVGA, XVGA, 1080i / 50Hz, 1080i / 60Hz, 480P, 720P, 1080P, etc. are ...

Abstract

This invention relates to a high resolution color TV variable debugging method, which only needs to debug one scanning mode in geometric debugging and automatically stores the debugged parameter in the addresses of other scan mode and signal format by the program to be added automatically with the computed modified value pr-stored in said address after debugging, the debugged fixed value is: the debugged parameter plus modified value, only trimming is enough to the signal format to other scan modes. The white balance debug is done under the AV state, the finished parameters are stored in the addresses of VGA, YprPb formats added with the computed modified value after large amount of debugging to input the result and fix it.

Description

technical field [0001] The invention relates to a debugging method for a high-definition color television set. Background technique [0002] At present, my country's TV is in an era of replacement. Digital high-definition color TVs (including various digital TVs) are becoming more and more popular. The acceptable signal formats (VGA, Y PR PB), scan mode ( 60P, 75I, 75P) are also increasing. But along with the continuous enhancement of functions, it has brought certain impact on TV production and debugging. In the prior art, the debugging method of high-definition color TV set is: for different signal input interfaces such as: computer (VGA), digital high-definition (Y Pr Pb) and so on to input the corresponding format signal for debugging: such as VGA, SVGA, XVGA, for different scanning modes such as 1080i / 50Hz, 1080i / 60Hz, 480P, 720P, 1080P, etc. also need to input the corresponding format signal for debugging. [0003] For example, as the top...
