Abstract

The invention relates to the field of flat-panel televisions and discloses an automatic color debugging method for a panel display system. The automatic color debugging method specifically comprises the following steps: the step 1, setting color coordinates of to-be-debugged colors: 1v, x and y mean debugging target values, and delta 1v, delta x and delta y mean allowable error ranges; the step 2, manufacturing standard color debugging signals; the step 3, detecting test values of LV, X and Y of the to-be-debugged color signals in the step 2 and comparing whether difference between the debugging target values and the test values meets the allowable error ranges. If the difference between the debugging target values and the test values meeting the allowable error ranges, the to-be-debugged colors meets color standard; and if one or several of the LV, X and Y cannot meet the allowable error ranges, a rear end chip is controlled to sequentially adjust the size of the LV, X and Y until the to-be-debugged colors meet color standard. The standard values are utilized to automatically debug colors, so that difference caused by color understanding of subjective factors is eliminated to the maximum degree, and display uniformity of the color terminal is achieved.

Description

The colored automatically debug method of a kind of flat panel display systems

Technical field

The present invention relates to panel TV field, particularly relate to the colored automatically debug method of a kind of flat panel display systems.

Background technology

In panel TV display field, colour is the important component part of reflection television set subjective effect quality.Because the sensitivity of human eye to colour also exists individual difference, different commissioning staffs has different understanding to colour, and in prior art, commissioning staff often to debug machine the subjective judgement of colour according to oneself and corrects.The direct result caused like this is exactly that the different people machine debugging out or the same person different time machine debugging out may also exist larger difference on colour.

Summary of the invention

The object of the invention is for the problems referred to above, provide a kind of flat panel display systems colored automatically debug method.

Object of the present invention is realized by following technical proposals:

The colored automatically debug method of a kind of flat panel display systems, it specifically comprises following steps:

Step 1. sets the chromaticity coordinates of color to be debugged: wherein lv, x, y represent debug target value, and Δ lv, Δ x, Δ y represent the error range of permission;

The colored debug signal of step 2. production standard;

Test value LV, X, Y of color signal to be debugged in step 3. detecting step 2, whether the difference comparing debug target value and test value meets the error range allowed, if met, then color to be debugged meets color standard; If one or more satisfied error range allowed of LV, X, Y, then control the size of back-end chip to LV, X, Y and sequentially adjust, until color to be debugged meets color standard.

Preferably, the method concrete steps sequentially adjusted the size of LV, X, Y in above-mentioned steps 3 are as follows:

If | lv-LV|> Δ lv, first controls back-end chip and adjusts to meet to LV size | lv-LV|< Δ lv;

If | lv-LV|< Δ lv, but | x-X|> Δ x or/and | y-Y|> Δ y, controls back-end chip and carries out adjustment to the size of LV, X, Y and meet | lv-LV|< Δ lv, | x-X|< Δ x, | y-Y|< Δ y.

Preferably, the normal color modulation signal in above-mentioned steps 2 is with the grayscale signal of motion for background, and middle window is color signal to be debugged, and different Color pair should ensure that signal is the substantially constant Dynamic Signal of mean flow rate by different motion GTGs.

Beneficial effect of the present invention: the standard value of code requirement carries out colored automatic Debugging, eliminates the product differentiation that the understanding of subjective factor to colour causes on the one hand to greatest extent, realizes the consistency of colored terminal demonstration.Colored automatically debug method of the present invention also improves operating efficiency simultaneously, reduces debugging cost.Thought of the present invention can also be generalized to the debugging of other project, such as brightness, saturation etc.

Accompanying drawing explanation

Fig. 1 is the flow chart of the colored automatically debug method of a kind of flat panel display systems.

Embodiment

Below in conjunction with specific embodiments and the drawings, the present invention is further illustrated.

The flow chart of the colored automatically debug method of a kind of flat panel display systems as shown in Figure 1, it specifically comprises following steps:

Step 1. sets the chromaticity coordinates of color to be debugged: wherein lv, x, y represent debug target value, and Δ lv, Δ x, Δ y represent the error range of permission.Wherein lv, x, y are international chromaticity coordinates representation.

The colored debug signal of step 2. production standard.

Test value LV, X, Y of color signal to be debugged in step 3. detecting step 2, whether the difference comparing debug target value and test value meets the error range allowed, if met, then color to be debugged meets color standard; If one or more satisfied error range allowed of LV, X, Y, then control the size of back-end chip to LV, X, Y and sequentially adjust, until color to be debugged meets color standard.

Preferably, the method concrete steps sequentially adjusted the size of LV, X, Y in above-mentioned steps 3 are as follows:

If | lv-LV|> Δ lv, first controls back-end chip and adjusts to meet to LV size | lv-LV|< Δ lv.Generally first can judge lv-LV>0 or lv-LV<0, adjust LV for different situations.

If | lv-LV|< Δ lv, but | x-X|> Δ x or/and | y-Y|> Δ y, controls back-end chip and carries out adjustment to the size of LV, X, Y and meet | lv-LV|< Δ lv, | x-X|< Δ x, | y-Y|< Δ y.

Preferably, with the grayscale signal moved for background, middle window (as 4%) is defined as color signal to be debugged, and different Color pair should ensure that signal is the substantially constant Dynamic Signal of mean flow rate by different motion GTGs.

We are example with yellow (yellow is called for short Y), illustrate process and the method for colored automatic Debugging.
