Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0026] The present invention is a method of importing the white luminance parameters of the display panel to calculate the gray-scale white balance gain value based on the white optical characteristics of the display panel to improve the accuracy of its gray-scale white balance adjustment. The method is applied to a display, and when When the display receives an input signal carrying original white information and displays an original white on a panel of the display according to the input signal, the method can measure and obtain a set of original stimulus values ​​of the original white Thro...

Abstract

The invention discloses a method which is characterized in that a gray scale white balance yield value is calculated by importing white color luminance parameters of a display device panel according to display device panel white color optical properties, and therefore gray scale white balance adjustment and calibration precision of the display device panel can be improved. The method is applied to a display device. The display device employing the method can effectively solve the problem that time and manpower are wasted due to conventional hand-operated gray scale white balance adjustment and calibration, and consistency displayed by frames of the display device can be improved because the white color brightness parameters of the display device are corrected.

Description

technical field [0001] The invention relates to a method for adjusting the gray-scale white balance of a display, especially a method that can automatically measure and adjust the gray-scale white balance of a display, and improve the accuracy of the adjustment by detecting the white brightness parameters of the display panel. The method is used to solve the labor hours and labor cost of traditional manual adjustment, and to make the display show the best color performance. Background technique [0002] In order to achieve the purpose of interactive communication with users, many electronic devices (such as: televisions, personal computers, digital photo frames, personal digital assistants or smart phones, etc.) are equipped with a display so that users can watch the Various information presented on it. As a medium for conveying visual information, the picture performance of the display has always been the focus of research and development in related technical fields. Ther...
