Abstract

The invention discloses a method for improving the color temperature consistency of a flat panel television through multiple gamma curves, and relates to the field of flat panel television flat screen modules. The method comprises the following steps that the color temperature range of screen modules adopted by the flat panel television is determined; the color temperature range of the screen modules is graded; gamma debugging is conducted on screen module samples within each color temperature grade to enable the debugged color temperatures to be within the required color temperature range; the correspondingly-debugged gamma curves are combined into television software; the color temperature grades of all the screen modules on a production line are determined through testing, and the corresponding gamma curves are selected from the television software to complete subsequent production. According to the method, on the basis that the cost of existing flat panel televisions and screen modules is not increased, the displayed color temperatures are all controlled to be within the required range after the flat panel televisions with the same type of screen modules are produced, and therefore the color temperature consistency is improved.

Description

A plurality of gamma is utilized to improve the conforming method of flat panel TV colour temperature
Technical field
The present invention relates to flat panel TV flat screen module field, be specifically related to one and utilize a plurality of gamma to carry The high conforming method of flat panel TV colour temperature.
Background technology
Along with the flat panel TV market competition grows in intensity, each producer, in order to reduce cost, makes same model screen module The situation that colour temperature differs greatly occurs.Conventionally, utilize a gamma for the institute of same model There is screen module to use, flat panel TV the most also there will be the situation that colour temperature difference is big, not only affect TV Subjective effect, and affect the sale of TV.If by front-end control the used components and parts of screen module Promote the colour temperature concordance of screen module, it is meant that cost will be significantly increased.
Summary of the invention
It is an object of the invention to for the deficiency in above-mentioned background technology, it is provided that one utilizes a plurality of gamma bent Line improves the conforming method of flat panel TV colour temperature, does not increase any cost at existing flat panel TV and screen module On the basis of, transfer a plurality of gamma by storage and promote the colour temperature concordance of flat panel TV.
In order to reach above-mentioned technique effect, the present invention takes techniques below scheme: utilize a plurality of gamma bent Line improves the conforming method of flat panel TV colour temperature, comprises the following steps:
A. the reference color temperature that the screen module that flat panel TV is used exists is determined;
B. the reference color temperature that described screen module exists is carried out divided rank;
C. the screen module sample in each color temperature levels is carried out gamma debugging, make the colour temperature after debugging be in In the reference color temperature required;
D. the gamma that correspondence is debugged out is incorporated in TV software;
E. test determines each screen module color temperature levels on production line, selects corresponding gamma in TV software Curve, completes subsequent production.
As preferably, in step a, determine reference color temperature with the different big screen module of color temperature difference between individuality for object.
As preferably, determine that the reference color temperature of 50 cun of screen modules is 7000K~13000K.
As preferably, the colour temperature of described 50 cun of screen modules is divided into three color temperature levels: 7000K~9000K, 9001K~11000K, 11001K~13000K;Screen module sample in each grade is carried out gamma debugging, The colour temperature making the screen module of each reference color temperature finally export is 10000K;3 gamma songs that debugging is completed Line is all incorporated in TV software;Finally, test determines each screen module color temperature levels on production line, at TV Software selects corresponding gamma, completes subsequent production.
The present invention compared with prior art, has a following beneficial effect: technical key point be by The screen module that colour temperature differs greatly is classified by colour temperature, more each grade screen module is carried out gamma debugging and closed Enter software, transfer corresponding gamma in software when producing according to the reference color temperature of individuality screen, finally make The colour temperature of flat panel TV is in the reference color temperature of requirement, it is achieved colour temperature concordance.The present invention is existing flat On the basis of plate TV and screen module do not increase any cost, transfer a plurality of gamma by storage and carry Rise the colour temperature concordance of flat panel TV, make the flat panel TV of same model screen module after completing to produce, show The colour temperature gone out all controls in the range of requiring, improves colour temperature concordance.
Accompanying drawing explanation
Fig. 1 is flow chart of the present invention;
Fig. 2 is that gamma of the present invention debugs system block diagram.
Detailed description of the invention
Below in conjunction with embodiments of the invention, the invention will be further elaborated.
Embodiment:
As shown in Figure 1, 2, a plurality of gamma is utilized to improve the conforming method of flat panel TV colour temperature, bag Include following steps:
A. the reference color temperature that the screen module that flat panel TV is used exists is determined, preferably different with color temperature difference between individuality Big screen module is that object determines reference color temperature.
B. the reference color temperature that described screen module exists is carried out divided rank;
C. the screen module sample in each color temperature levels is carried out gamma debugging, make the colour temperature after debugging be in In the reference color temperature required;
D. the gamma that correspondence is debugged out is incorporated in TV software;
E. test determines each screen module color temperature levels on production line, selects corresponding gamma in TV software Curve, completes subsequent production.
Below, as a example by 50 cun of screen modules that flat panel TV uses, the present embodiment is described in detail
A. determine that 50 cun of reference color temperatures shielding modules are 7000K~13000K.
B. the colour temperature of described 50 cun of screen modules is divided into three color temperature levels: 7000K~9000K, 9001K~11000K, 11001K~13000K;
C. the screen module sample in each grade being carried out gamma debugging, the screen module making each reference color temperature is final The colour temperature of output is 10000K;
D. 3 gamma debugging completed all are incorporated in TV software;
E. test determines each screen module color temperature levels on production line, selects corresponding gamma in TV software Curve, completes subsequent production.
It is understood that the principle that is intended to be merely illustrative of the present of embodiment of above and the example that uses Property embodiment, but the invention is not limited in this.For those skilled in the art, Without departing from the spirit and substance in the present invention, various modification and improvement can be made, these modification It is also considered as protection scope of the present invention with improvement.
