Embodiment Construction

[0027] Specific structural and functional details disclosed herein are representative only and for purposes of describing example embodiments of the present invention. This invention may, however, be embodied in many alternative forms and should not be construed as limited to only the embodiments set forth herein.

[0028] see figure 1 , figure 1 It is a method flow chart of a dual-display color correction method provided by the present invention. In one embodiment, a method for color correction of dual display screens provided by the present invention includes the following steps:

[0029] Step 1 (S01): Select the reference voltages of the color scales of the dual display screens respectively.

[0030] Step 2 (S02): Comparing the reference voltages selected from the dual display screens to obtain a voltage difference.

[0031] Step 3 (S03): Comparing the voltage difference with the initialization value of the color scale of the dual display screens, determining a compensa...

Abstract

The invention discloses a double-display-screen color correction method which is used for correcting reference voltage of color gradation of double display screens and comprises the following steps: firstly, respectively selecting reference voltages of color gradation of double display screens; comparing the reference voltages selected from the double display screens to obtain a voltage difference; and comparing the voltage difference with the initialized value of the color gradation of the double display screens to determine a compensation value, and compensating the initialized value; and writing the compensated initialized value into the double display screens. Therefore, the colors presented by the double display screens are closer to or even the same.

Description

technical field [0001] The invention relates to a color correction method for dual display screens, in particular to a color correction method and a correction system for dual display screens used in a 3D image system. Background technique [0002] In the current display technology, taking large-size monitors and TVs as examples, the voltage of the driver chip of the display module is uniformly provided by the power converter in the module, so the reference for multiple driver chips in such a large-size module The analog voltages are all the same, so that the voltages output by the respective driver chips to the panel circuit will have the same color in the same gray scale. However, in small and medium-sized modules composed of a single driver chip, because the reference voltages generated in each module are not consistent, when two modules are assembled in the same 3D application system, it will be due to Slight voltage differences cause patterns of the same gray scale to ...
