Embodiment Construction

[0032] The specific implementation manner of the display system provided by the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] An embodiment of the present invention provides a display system, such as figure 1 As shown, it includes: a display panel 10, a backlight module 20 using light-emitting diodes and laser diodes as backlight sources, a first drive unit 31 for driving the light-emitting diodes to emit light, a second drive unit 32 for driving the laser diodes to emit light, And the control module 40 connected with the first drive unit 31 and the second drive unit 32 respectively; Wherein,

[0034] The control module 40 is used to collect the image signal to be displayed in the display panel 10, and determine whether image quality compensation is required for the image to be displayed; to emit light; if not, only control the first driving unit 31 to drive the light emitting diode to emit light. ...

Abstract

The invention discloses a display system. A light emitting diode and a laser diode are used as a backlight source for a display panel and correspondingly provided with a first drive unit driving the light emitting diode to emit light and a second drive unit driving the laser diode to emit laser respectively, a control module acquires an image signal to be displayed on the display panel and confirms whether an image to be displayed needs image quality compensation or not, controls the first drive unit and the second drive unit to respectively drive the light emitting diode and the laser diode to emit light jointly if the image to be displayed needs image quality compensation and only controls the first drive unit to drive the light emitting diode to emit the light if the image to be displayed does not need the image quality compensation. Compared with the situation that a liquid crystal display in the prior art only uses the light emitting diode as the backlight source for the display panel, a color gamut range of the liquid crystal display can be effectively widened, the color saturation of a display frame can be effectively improved, the image quality definition is improved well, and the display frame can be real and have gradation sensation.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display system. Background technique [0002] As we all know, liquid crystal displays have many advantages that other displays cannot match, such as low power consumption, small size, light weight, and ultra-thin screen. In recent years, they have been widely used in smart instruments, meters and low-power electronic products controlled by single-chip computers. At present, most liquid crystal displays on the market use light-emitting diodes as a backlight source, which can realize wide color gamut display of liquid crystal displays. [0003] The color gamut of traditional liquid crystal displays can only reach about 70%. As people have higher and higher requirements for the quality of display images, traditional liquid crystal displays can no longer meet people's needs. According to the principles of optics and colorimetry, blue light-emitting diodes and yellow-emitt...
