Abstract
High-color-saturation liquid crystal display module structurally comprises the following components from top to bottom: a polaroid, a liquid crystal display screen, a lower polaroid, black-white double faced adhesive tape, a brightness enhancement film, a main FPC, a backlight FPC and a red LED chip. The display module further comprises a blue lower diffusion film and a green light guide plate. Furthermore the blue lower diffusion film and the green light guide plate are provided between the brightness enhancement film and the backlight FPC. According to the high-color-saturation liquid crystal display module, through the red light which is emitted from the red LED chip, the green light guide plate and the blue lower diffusion film, the red light is mixed to white light. Thus not only are high firmness and high accuracy in LED chip positioning obtained, but also the high-color-saturation liquid crystal display module has the following advantages: simple structure, high realizing convenience, reduced cost, high economic performance and high practicability. The white light has higher color saturation. The color saturation of the liquid crystal display module with the assembly can reach 80%-90%.
Description
Technical field
The utility model relates to field of liquid crystal display, relates in particular to a kind of high color saturation liquid crystal display module.
Background technology
Module backlight (Back Light Module) is one of basic spare part except that display panels (LCD Panel), and main effect is to make the normal show image of LCD ability for LCD provides the light source that brightness is sufficient and be evenly distributed.
The small-medium size liquid crystal display module that exists on the market now is by the LED in the module backlight white light source to be provided; And the LED white light source mainly is the white light that the blue light that sent by blue chip and yellow fluorescent powder proportioning blend, the LGP in the module backlight then and down diffusion barrier all be transparent material.
Shown in Figure 1 is traditional liquid crystal display module structure, and one group of liquid crystal module structure comprises polaroid 1 from top to bottom, LCD2, following polaroid 3; And two polaroids must be close to LCD2 up and down, are black and white double faced adhesive tape 4 then, last bright enhancement film 5, following bright enhancement film 6; Following diffusion barrier 7, LGP 8, glue frame 9, reflector plate 10; Chase 11, main FPC101, FPC102 backlight.Wherein, the light that led chip 103 sends is for blue, and the blue-light source that the liquid crystal display module uses the LED blue chip to send adds last layer yellow fluorescent powder proportioning then and goes out white light.
The color saturation of this kind white light is relatively poor.Use the color saturation of the liquid crystal display module of this LED to have only about 50%.This liquid crystal display module gives user's sensation relatively dulller.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of simple in structure and high color saturation liquid crystal display module that cost is low.
The technical scheme that the utility model adopted is: a kind of high color saturation liquid crystal display module, its structure comprise polaroid, LCDs from top to bottom successively, following polaroid; The black and white double faced adhesive tape; Bright enhancement film, main FPC, FPC backlight and red LED chips; This demonstration module also comprises blue diffusion barrier and green LGP down, and blue diffusion barrier down and green LGP are between bright enhancement film and FPC backlight.
Said polaroid comprises polaroid and following polaroid, and two polaroids are close to LCDs up and down.
Said bright enhancement film comprises bright enhancement film and following bright enhancement film.
Said liquid crystal display module also comprises the glue frame, reflector plate and chase.
Contain green developer in the said green LGP.
Contain blue scattering particle under the said blueness in the diffusion barrier.
Ruddiness and green LGP that the utility model sends through the LED red chip, the following diffusion with blueness is mixed into white light again, so not only makes the led chip location more firm; More accurate, and simple in structure, and it is convenient to realize; Also reduced cost; More economical practicality, the color saturation of this white light is higher, uses the color degree of saturation of the liquid crystal display module of this combination can reach 80%-90%.
Description of drawings
Shown in Figure 1 is traditional liquid crystal display module structural representation.
Shown in Figure 2 is the utility model liquid crystal display module structural representation.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Shown in Figure 2 is the utility model liquid crystal display module structure.This patent liquid crystal module structure comprises polaroid 1, LCDs LCD2 from top to bottom successively, following polaroid 3, and two polaroids must be close to LCD2 up and down, are black and white double faced adhesive tape 4 then; Last bright enhancement film 5, following bright enhancement film 6, blue diffusion barrier 12 down; Green LGP 13, glue frame 9, reflector plate 10; Chase 11, main FPC101, FPC102 backlight and led chip 104.Wherein, the light that led chip 104 sends is redness, and the liquid crystal display module uses the LED red chip to send red light source, and light is reached our needed white light through green LGP 13 and blue 12 mixing of diffusion barrier down then.Wherein, green LGP 13 is in the manufacturing process of LGP, to add green developer, makes its LGP present green.Blue diffusion barrier 12 down is through descending the scattering particle on the diffusion barrier to dye blueness, and be applied to down then on the diffusion barrier, and making down diffusion barrier present blueness.
Ruddiness and green LGP that the utility model sends through the LED red chip, the following diffusion with blueness is mixed into white light again, and the color saturation of this white light is higher.Use the color degree of saturation of the liquid crystal display module of this combination can reach 80%-90%, this liquid crystal display module can be more bright-coloured to people's sensation.
Although the embodiment of the utility model is open as above; But it is not limited only to listed utilization in instructions and the embodiment; It can be applied to the field of various suitable the utility model fully, for being familiar with those skilled in the art, can easily realize other modification; Therefore under the universal that does not deviate from claim and equivalency range and limited, the legend that the utility model is not limited to specific details and illustrates here and describe.
