Problems solved by technology

[0003] In recent years, with the rapid development of my country's home appliance industry, fields such as smart phones, large-screen TVs, and computers have gradually entered the homes of ordinary people. However, backlight modules are widely used in smart phones, large-screen TVs, and computers. With the continuous increase of people's work pressure, the amount of eyes used for the above-mentioned electronic products is gradually increasing, which will cause different degrees of damage to people's eyes. Therefore, we have invented an eye protection backlight module, which is very practical significance

Embodiment 1

[0021] This example provides Figure 1-3 The shown eye protection backlight module includes an eye protection device 1, a module frame 4 and a housing 14, the eye protection device 1 is fixedly connected to the liquid crystal panel 3 through the backlight module 2, and the eye protection device 1 includes A housing 14, an electronic ballast 17 is provided inside the housing 14, an optical splitter 15 and a PLC controller 16 are arranged in sequence below the electronic ballast 17, and the backlight module 2 includes a module frame 4. One side of the module frame 4 is provided with a light-transmitting hole 10, and the inside of the module frame 4 is provided with an upper diffusion sheet 9, and the upper diffusion sheet 9 passes through the upper light-collecting sheet 11 and the lower light-collecting sheet 8 are fixedly connected, the lower light-collecting sheet 8 is fixedly connected to the light guide plate 13 through the lower diffusion sheet 12, the two ends of the lowe...

Embodiment 2

[0030] The structure and working principle of an eye-protecting backlight module in this embodiment are the same as those in Embodiment 1, except that the reflection-enhancing coating is made of zinc chloride, acrylic acid, sulfonated castor oil, zircon sand, white corundum, water According to the weight ratio of 2:1.6:2:0.5:0.5:10, the mixture is evenly coated on the inner wall of the light-transmitting hole and dried. Specifically, in this embodiment, the reflection-enhancing coating is composed of zinc chloride, acrylic acid, sulfonated castor oil, zircon sand, white corundum, and water in a weight ratio of 2g: 1.6g: 2g: 0.5g: 0.5g: 10g The composed mixture is evenly coated on the inner wall of the light-transmitting hole and dried. By coating the inner wall of the light-transmitting hole with a specially formulated reflection-enhancing coating, the light-transmitting property of the light-transmitting hole is significantly enhanced, and the utilization rate of light is eff...

Embodiment 3

[0032] The structure and working principle of an eye-protecting backlight module of this embodiment are the same as those of Embodiments 1 and 2, except that the reflection enhancing coating is made of zinc chloride, acrylic acid, sulfonated castor oil, zircon sand, white corundum , The mixture composed of water according to the weight ratio of 1:1.2:1:0.3:0.3:5 is evenly coated on the inner wall of the light-transmitting hole and dried. Specifically, in this embodiment, the reflection enhancing coating is composed of zinc chloride, acrylic acid, sulfonated castor oil, zircon sand, white corundum, and water according to the weight ratio of 1g: 1.2g: 1g: 0.3g: 0.3g: 5g The composed mixture is evenly coated on the inner wall of the light-transmitting hole and dried. By coating the inner wall of the light-transmitting hole with a specially formulated reflection-enhancing coating, the light-transmitting property of the light-transmitting hole is significantly enhanced, and the uti...

Abstract

The invention discloses an eye protecting backlight module. An eye protecting device is fixedly connected with a liquid crystal panel through a backlight module; the eye protecting device comprises a shell; an electronic ballast is arranged inside the shell; a light-way divider and a PLC (Programmable Logic Controller) are arranged in sequence below the electronic ballast; the backlight module comprises a module frame; one side of the module frame is provided with light-transmission holes; an upper dispersing sheet is arranged inside the module frame; the upper diffusing sheet is fixedly connected with a lower light collecting sheet through an upper light collecting sheet; the lower light collecting sheet is fixedly connected with a light guiding plate through a lower dispersing sheet; two ends of the lower dispersing sheet and two ends of the light guiding plate are all provided with cold cathode fluorescent lamp tubes. The eye protecting backlight module is scientific and reasonable in design and simple in structure; not only can the luminance of the backlight module be improved, but also the backlight module is enabled to emit light more uniformly; light rays are gentle; the visual fatigue can be reduced; a quite good eye protecting effect is realized; the practicability is higher; the eye protecting backlight module is worth energetically popularizing.

Description

technical field [0001] The invention belongs to the technical field of backlight modules, and in particular relates to an eye-protection backlight module. Background technique [0002] With the continuous development of liquid crystal display technology, the application fields of liquid crystal displays, especially color liquid crystal displays, are also constantly expanding. Driven by the liquid crystal display market, the backlight industry is showing a scene of prosperity. The LCD is a non-luminescent display device, which needs a backlight source to achieve the display function. The performance of the backlight will not only directly affect the image quality of the LCD, the cost of the backlight accounts for 30-50% of the LCD module, and the power consumption accounts for 75% of the module, which can be said to be a very important part of the LCD module. components. High-definition and large-size LCDs must be matched with high-performance backlight technology. Therefo...
