Embodiment 1

[0017] Such as figure 1 As shown, an automatic white balance online debugging system for flat panel display products, which includes a color temperature acquisition analyzer, a host computer and a flat panel display product, the color temperature acquisition analyzer adopts the CA-310 model, the host computer is a PC, and the flat panel display product is for example Flat screen TV and more. The color temperature acquisition and analyzer is used to obtain the color temperature of the current flat panel display product and convert the x and y color coordinates to the upper computer. The upper computer is used to analyze the x and y color coordinate values ​​transmitted by the color temperature acquisition analyzer, and read and write registers and send storage instructions to the flat panel display products; the flat panel display products analyze the storage instructions issued by the upper computer, and automatically read the relevant register values , converted into white b...

Embodiment 2

[0020] An automatic white balance online debugging method for flat panel display products, characterized in that: comprising the following steps in sequence:

[0021] a. The color temperature acquisition analyzer obtains the color temperature of the current flat panel display product and converts the x, y color coordinate values, and transmits them to the host computer.

[0022] b. The upper computer analyzes the x and y color coordinate values ​​transmitted by the color temperature acquisition analyzer, and continuously adjusts the relevant register values ​​of the flat panel display product. When the measured x and y color coordinate values ​​are within the target value range, the upper computer issues a storage command . Pre-data collection is used to count the best default data, and at the same time cooperate with first detection and then calibration. If the default x and y color coordinates are found to be within the default target value range, no calibration is required,...

Abstract

The invention discloses an automatic white balance online regulation system and method for a flat-panel display product, and relates to the technical field of picture quality of flat-panel display products. The automatic white balance online regulation system for the flat-panel display product comprises a color temperature acquisition analyzer, an upper computer and the flat-panel display product. The regulation method comprises the steps that the color temperature acquisition analyzer acquires the current color temperature of the flat-panel display product, performs conversion to obtain x and y color coordinate values, and transmits the x and y color coordinate values to the upper computer; the upper computer analyzes the x and y color coordinate values transmitted by the color temperature acquisition analyzer, continuously regulates a related register value of the flat-panel display product, and transmits a storage instruction when the x and y color coordinate values are measured to be within a target value range; the flat-panel display product parses the storage instruction transmitted by the upper computer, automatically reads the related register value, converts the related register value into a white balance parameter, and stores the white balance parameter into a data storage area. The system and the method have the advantages of short calibration time, production cost saving, simple software implementation, high transplantability and the like.

Description

technical field [0001] The invention relates to the technical field of image quality of flat panel display products, in particular to an automatic white balance online debugging system and method for flat panel display products. Background technique [0002] In the production of flat-panel display products, due to the poor consistency of the color temperature of the same batch of display screens, we cannot satisfy the consistency of subjective image quality with fixed white balance parameters. To solve this contradiction, we must Each machine on the production line adjusts the white balance parameters online. At present, manual adjustment is used, which has low production efficiency and large errors. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the above-mentioned background technology, provide an automatic white balance online debugging system and method for flat panel display products, and solve the large col...
