Also disclosed is a light having a backlight module and a liquid crystal display having the light guide plate. A light conversion element is accommodated in the light guide plate, so as to avoid over-heating the light conversion element to further avoid reducing the color gamut of the product.
Abstract:
A liquid crystal display module and a method for manufacturing the liquid crystal display module are disclosed. The liquid crystal display module comprises a reflective sheet, a frame body, a frame, and a light guide plate. The frame body includes a base plate having an upper surface which is provided with an accommodating area for accommodating the reflective sheet. The reflective sheet is partially or completely accommodated in the accommodating area, so that the liquid crystal display module can be thinned. Moreover, the overall strength of the liquid crystal module can be ensured. In addition, the material for the base plate can be effectively saved, which is beneficial for saving costs.
Abstract:
A backlight source, a method for manufacturing the backlight source, and a liquid crystal display are provided. The backlight source comprises a printed circuit board and a linear light source arranged on a surface of the printed circuit board, wherein the linear light source is configured as an integral module including a plurality of point light sources located in one and the same plane. The method comprises: step (a): providing a package trough member, and packaging the plurality of point light sources in the package trough member in such a manner that the plurality of point light sources are located in one and the same plane, so as to form a linear light source; and step (b): fixedly arranging the linear light source on the surface of the printed circuit board. The linear light source being configured as an integral module of the backlight source ensures excellent flatness thereof, thus improving light-emitting effects of the backlight source and display effects of the liquid crystal display.
Abstract:
The present invention provides an LCD and an LC module of narrow bezel thereof. The LC module of narrow bezel includes a case; an LC panel; a BLU; and a buffer material, wherein the LC panel and the BLU are stacked in the case and widths of the LC panel and the BLU are the same. The buffer material is set on one side or two sides of a region between the BLU and the case. The present invention provides an LCD and an LC module of narrow bezel thereof. The widths of the LC panel and the BLU are the same and the buffer material is set on one side or two sides of a region between the BLU and the case so the interval between the LC module and the bezel (the case) becomes narrow and the narrow bezel of the LCD is performed.
Abstract:
A light source module is disclosed. The light source includes: a power supply board; a plurality of LED chips arranged on a surface of the power supply board in a matrix; and a light guiding housing arranged above the power supply board, a bottom surface of the light guiding housing is bonded with a surface of the power supply board so as to encapsulate the LED chips between the light guiding housing and the power supply board. In addition, a backlight module including the light source module is also disclosed. The LED chips are mounted on the surface of the power supply board, and a light reflection layer is coated on the surface. The power supply board is integrated with the light guiding housing above the LED chip to form an integral light module so as to enhance the ratio of the visible area of the liquid crystal device.
Abstract:
A backlight module includes a backlight assembly for generating a backlight source, and the upper surface of the backlight assembly is an optical film, and a light shading layer is spayed around the upper surface of the optical film. Though spraying the light shading layer around the optical film, the backlight module of the present invention finely solves the defects of the prior art, i.e., the process for mechanically cutting the black double-faced adhesive tape is complicate, and the narrow bezel display can hardly be achieved, meanwhile, it increases the optical taste of the display products.
Abstract:
The invention discloses a backlight module, comprising: a light guide plate provided with a strip-shaped slot, a light bar, which comprises a base plate and a plurality of mounting bases mounted on the base plate, each mounting base is provided with a lighting element respectively, wherein the base plate of the light bar is configured to engage with the first surface of the light guide plate, such that all the mounting bases can be accommodated within the strip-shaped slot. It is unnecessary for the backlight module to set up rubber frame and back plate, hence, the backlight module without outer frame border is formed.
