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.

Test value LV, X, the Y of color signal to be debugged in step 3. detecting step 2, relatively whether the difference of debug target value and test value satisfies the error range that allows, if satisfy, then color to be debugged meets color standard; If LV, X, one or more satisfied error range that allows of Y are then controlled back-end chip the size of LV, X, Y are sequentially adjusted, until color to be debugged meets color standard.
Preferably, the method concrete steps of in the above-mentioned steps 3 size of LV, X, Y sequentially being adjusted are as follows:
If | lv-LV|〉Δ lv, at first control back-end chip the LV size adjusted to satisfy | lv-LV|＜Δ lv;
If | lv-LV|＜Δ lv, still | x-X|〉Δ x or/and | y-Y|〉Δ y, the control back-end chip is adjusted to satisfy to the size of LV, X, Y | lv-LV|＜Δ lv, | x-X|＜Δ x, | y-Y|＜Δ y.
Preferably, the standard color modulation signal in the above-mentioned steps 2 is take the GTG signal of motion as background, and middle window is color signal to be debugged, and the corresponding different motion GTGs of different color guarantee that signal is the substantially constant Dynamic Signal of mean flow rate.
Beneficial effect of the present invention: the standard value of code requirement is carried out colored automatic Debugging, has eliminated to greatest extent on the one hand subjective factor to the product differentiation that the understanding of colour causes, and realizes the consistency that colored terminal shows.Colored automatically debug method of the present invention has also improved operating efficiency simultaneously, has reduced debugging cost.Thought of the present invention can also be generalized to the debugging of other project, for example brightness, saturation etc.
