Abstract

The invention provides a display device and a light source correction method for the display device. The display device comprises a liquid crystal module, a back cover, light sources and a sensing module; the sensing module is used for measuring red light values, blue light values, green light values and white light values of the light sources; the light sources and the sensing module are arranged between the liquid crystal module and the back cover; the light source correction method comprises the following steps of starting the light sources, and measuring a first red light value, a first blue light value, a first green light value and the white light value of the light sources; calculating an infrared light value according to the first red light value, the first blue light value, the first green light value and the white light value, and subtracting the infrared light value from one of the first red light value, the first blue light value and the first green light value for correcting the supplied electric energy of the light sources. According to the display device and the light source correction method for the display device, provided by the invention, in consideration of the influences of infrared rays on measured values, the problems of bright reduction and color bias of the display device in the prior art are solved.

Description

technical field

[0001] The invention relates to a display device and a light source correction method of the display device, in particular to a display device and a method for correcting brightness and color temperature of a backlight source of the display device. Background technique

[0002] Display technology has developed rapidly in recent years, and expert-level displays that require precise color and brightness are gradually being used in professional fields such as art advertisement design, professional drawing displays, printing and publishing companies, and medical diagnosis that require high color quality of display units. , when working, the several monitors used must have the same screen display (such as brightness and color temperature, etc.) as possible to achieve the required image quality. These professional-level LCD monitors currently use LED light sources as The light source of the backlight module, the LED light source can be an LED light source with thre...

Embodiment Construction

[0025] In order to have a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed descriptions are provided in conjunction with the embodiments.

[0026] Please refer to figure 1The structure schematic diagram of the display device 10 of the present invention, the structure of the display device 10 includes: a liquid crystal module 130 , a back cover 140 , a light source 110 and a sensing module 120 . The light source 110 can be an LED light source module with three primary colors of red, blue, and green. When adjusting the light source, the power supply of the light source with three primary colors of red, blue, and green can be adjusted. In addition, the light source 110 can also use an LED light source module packaged by red and blue LED chips and green phosphor powder. When adjusting the light source, only the red and blue light sources can be adjusted for power supply. In the present invention, as long as ...
