Problems solved by technology

However, more and more users are in the environment of long-term contact with the display. Some medical literature and medical professionals have warned about the blue light wavelength emitted by the current display. Human eyes watch under the short-wave blue light display for a long time. Human eyes will gradually cause damage, and even lead to blindness in severe cases. Therefore, whether it is an LCD display that uses blue LED chips as its backlight source, or an OLED blue light display unit, it is necessary to design considerations for the damage of blue light to human eyes.

Abstract

The invention discloses a display device and a display driving method. The display device comprises a backlight module, a display panel arranged at a light outgoing surface of the backlight module, ablue light source arranged in the backlight module and a display driving circuit arranged on the display panel, and is characterized in that the first blue light wavelength of the blue light source isgreater than 440nm; the display driving circuit stores a blue light gamma curve of the blue light source; and the display driving circuit corrects the blue light source according to the blue light gamma curve. The display device can reduce influences imposed on the eyesight by blue light and improve the display image quality at the same time.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device and a display driving method. Background technique [0002] The display has many advantages such as thin body, power saving, no radiation, etc., and has been widely used. Most of the displays currently on the market are backlight displays, which include a display device and a backlight module. The working principle of the display device is to place liquid crystal molecules between two parallel substrates, and apply a driving voltage on the two substrates to control the rotation direction of the liquid crystal molecules, so as to refract light from the backlight module to generate images. [0003] Among them, Thin Film Transistor-Liquid Crystal Display (TFT-LCD) has gradually occupied a dominant position in the display field due to its low power consumption, excellent picture quality, and high production yield. Similarly, a thin film transistor display ...
