Problems solved by technology

The inventor of the present application has found in long-term research and development that although the existing design can greatly increase the brightness of the display, the viewing angle will be lost; especially when the LCD is viewed from the side, the original color of the screen cannot be seen, or even only the original color of the screen can be seen. Can see all white or all black, which is often referred to as the problem of insufficient viewing angle

Embodiment Construction

[0015] In order to make the object, technical solution and effect of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0016] see figure 1 , figure 1 It is a structural schematic diagram of an embodiment of the backlight module of the present invention. The invention provides a backlight module for providing a backlight source for a display device. The backlight module includes: a light source 101 and an optical film 102 .

[0017] The light source 101 is a point light source, a line light source or a surface light source, capable of emitting at least the first light; the light source 101 can be a light emitting diode (Light Emitting Diode, LED) lamp, and the LED lamp can emit light of various colors, such as ultraviolet light or blue light . In other implementation manners, the backlight source may also be other light-emitting chips or the like.

Abstract

The invention discloses light conversion film used in a backlight unit, the backlight unit and display equipment. The backlight module comprises a light source and the light conversion film, wherein the light source emits at least a first kind of light, the light conversion film receives the first kind of light and coverts the first light into at least a second kind of light and transmits out the second kind of light, so that the angle of the emergent light of the backlight unit is larger than 120 degrees, and the color temperature is smaller than 15,000. The light conversion film used in the backlight unit can magnify the angle of view of the display equipment, and can make the luminance angle of view reach 120 degrees or above; meanwhile, the light conversion film has high optical excitation efficiency, the color temperature of the backlight module can be lowered, and the displaying effect is further strengthened.

Description

technical field [0001] The invention relates to the technical field of liquid crystal panel display, in particular to a light conversion film used for a backlight module, a backlight module and a display device. Background technique [0002] Liquid Crystal Display (LCD) has the characteristics of light and thin, low power consumption, and no radiation. Computers, mobile phones, digital cameras and other electronic equipment. [0003] Most of the backlights used in LCDs at this stage are LEDs. Take the side-type backlight as an example. A certain number of optical films are used to shield mura or increase brightness. The inventor of the present application has found in long-term research and development that although the existing design can greatly increase the brightness of the display, the viewing angle will be lost; especially when the LCD is viewed from the side, the original color of the screen cannot be seen, or even only the original color of the screen can be seen. ...
