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

A display device and a display driving method. The display device comprises a backlight module (10), a display panel (20) disposed on a light exit surface of the backlight module (10), a blue light source (30) disposed in the backlight module (10), and a display driving circuit (40) disposed on the display panel (20). A first blue light wavelength of the blue light source (30) is greater than 440 nm. A blue light gamma curve of the blue light source (30) is stored in the display driving circuit (40). The display driving circuit (40) corrects the blue light source (30) according to the blue light gamma curve.

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, and no radiation, and has been widely used. Most of the displays on the current market are backlit 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 produce images. [0003] Among them, Thin Film Transistor-Liquid Crystal Display (TFT-LCD) has gradually occupied a leading position in the display field due to its low power consumption, excellent picture quality, and high production yield. Similarly, a thin film transistor display includes a dis...
