Embodiment Construction

[0019] The above-mentioned purpose of the present invention and its structural and functional characteristics will be further elaborated on the present invention according to the following drawings and specific implementation methods, please refer to figure 1 and figure 2 .

[0020] The present invention includes a flow chart and a schematic flow chart of the following three steps.

[0021] Step 1: Set up the light sensor on the front of the monitor

[0022] Setting the front light sensor 2 in front of the panel of the liquid crystal display 1 can avoid factors such as brightness attenuation caused by degradation of the liquid crystal display panel, and can obtain more accurate measurement data.

[0023] Step 2: Calibrate the front light sensor, and implement the following method to obtain the measured data, and compare it with the calibration reference device to obtain the difference. If the difference is less than the error range DeltaE(2000)<5, the calibration is success...

Abstract

The present invention provides a device and method for self-image correction of a liquid crystal display. The correction device includes the following steps: a front light sensor and a correction reference device, and the front light sensor is used for adjusting the grayscale and the gray scale of the display. The color temperature is calibrated, and the correction reference device is used to pre-calibrate the front light sensor; the beneficial effect of the present invention is to perform pre-image correction on the installed front light sensor when leaving the factory, and apply the corrected front light sensor The detector directly adjusts the gray scale and color temperature of the display screen, which is easy to install and can effectively detect and correct the display image. In this way, human resources can be saved, and the overall maintenance and manufacturing projects can be shortened.

Description

technical field [0001] The invention belongs to the technical field of display image correction, especially relates to a liquid crystal display self-image correction device and method, thereby saving human resources and shortening overall maintenance and manufacturing engineering. Background technique [0002] Press, in the field of general display image correction technology, it can be divided into two types: hardware correction and software correction. Hardware correction is to store the adjusted data in the storage device inside the display, and software correction is to use the color description file (ICCProfile). The operation of the computer is used to achieve the purpose of image correction. [0003] Traditional monitor calibration, whether it is hardware or software calibration, requires the use of external devices such as computers, colorimeters and other equipment, as well as professional software required to calibrate the monitor. It is not convenient to set up th...
