Description

Technical Field

[0001] The present invention belongs to the technical field of flat panel display, and in particular relates to an automatically corrected display panel. Background Art

[0002] Flat displays such as LCDs may have color casts in complex light environments. Traditional flat panel displays use only a single brightness sensor for the entire device, which samples the ambient light brightness of the entire device and adjusts the backlight brightness and other parameters of the entire device according to the ambient light brightness. For example, the brightness of the entire device is increased or decreased in brighter or darker environments to ensure that the contrast of the entire device is within the appropriate viewing range and to achieve energy saving and other purposes.

[0003] Despite this, existing solutions still have limited effects and are still unable to resolve the problem of complex ambient light (different color temperatures). Summary of the invention

[0004] The main purpose of the present invention is to provide an automatically corrected display panel to solve the problems existing in the prior art. A color temperature sensor is introduced into the display medium of the display panel to sample the irradiated light and adjust the luminescence of a single pixel and its neighboring pixels.

[0005] In order to achieve the above object, the solution of the present invention is: A display panel with automatic correction, wherein a single light-emitting unit of the display panel includes a group of single pixels or N pixel combinations, and a color temperature sensor; the pixel is composed of a red chip, a green chip, and a blue chip; the color temperature of the single pixel or the N pixel combination in the light-emitting unit irradiated by ambient light is collected by the color temperature sensor, and feedback compensation is performed through an algorithm to adjust the luminous brightness of the RGB three colors of the single pixel or the N pixel combination.

[0006] The number N of pixels in the N-pixel combination is a multiple of 4.

[0007] After adopting the above technical solution, the present invention has the following technical effects: The present invention adds a color temperature sensor in a light-emitting unit, collects the color temperature of a single pixel or a combination of pixels irradiated by ambient light in the light-emitting unit through the color temperature sensor, performs feedback compensation through an algorithm, and adjusts the RGB three-color luminous brightness of the single pixel or the combination of pixels, thereby achieving the purpose of automatically correcting the display effect; when N pixels form a combination and share a color temperature sensor, the cost can be reduced, the sensor window area of ​​a single pixel can be reduced, and the influence of the sensor on the image resolution can be reduced.
