Description

Narrow frame TFT leak protection photo structure

Technical Field

The utility model relates to a liquid crystal display's technical field more precisely relates to a narrow frame TFT leak protection photo structure.

Background

The ultra-narrow frame means that the proportion of a visible area in a mobile phone screen of the smart phone is higher, the visual effect is more excellent, and the attention of consumers can be attracted better. Among the prior art, liquid crystal display's fixed frame is made by the plastic material, and the plastic material has the light transmissivity, and the backlight is when luminous, and light can cause display screen module frame light leak through liquid crystal display's ejection of all around, has seriously influenced liquid crystal display's effect. The method solves the problem of light leakage of the frame of the display screen module, one method is to make the distance between a visible area and the edge of the display screen as large as possible, and cover a non-visible area by using the shell of the mobile phone, but the scheme can not realize the effect of no frame in vision; the other method is to adopt a black silk-screen backlight frame to shield the light leakage of the frame of the display screen module, and the apple company adopts the scheme to add black dye in raw materials, but the black dye absorbs light, so that the brightness of a visible area is lost by 20%, and the effect of a high-brightness product cannot be achieved.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a narrow frame TFT leak protection photo structure, solve the problem of the display screen module frame light leak of narrow frame cell-phone.

The technical solution of the utility model is that, a narrow frame TFT leak protection light structure is provided, including TFT display screen module and the backlight module of laminating in TFT display screen module below, TFT display screen module still is connected with FPC flexible line way board, and the backlight module includes the metal frame, the metal frame border around TFT display screen module form the metal barricade.

Compared with the prior art, the utility model discloses a narrow frame TFT leak protection photo structure has following advantage: a plastic frame around the TFT display screen module is eliminated, and a metal retaining wall is used to surround the periphery of the TFT display screen module, so that the visual frameless effect is realized, and the light leakage condition of the frame of the TFT display screen module is improved; the absorbance of the metal retaining wall is far less than that of the black dye, the brightness loss of the visible area can be ignored, and the effect of a high-brightness product is ensured.

Preferably, the metal retaining wall is only arranged on the straight edge of the periphery edge of the TFT display screen module, and the metal retaining wall is not arranged at each corner of the edge of the TFT display screen module. Because the general material of metal as the frame is harder, can not laminate well in each corner at TFT display screen module border, adopt this structure, can avoid influencing the laminating degree of the metal barricade on the flat limit in TFT display screen module border because the metal barricade of corner does not laminate TFT display screen module border.

Preferably, the metal retaining wall is made of SUS304 or SUS 201. The SUS304 material or the SUS201 material has low absorbance and is good in adhesion with the edge of the TFT display screen module.

Detailed Description

For a better understanding of the present application, various aspects of the present application will be described in more detail with reference to the accompanying drawings. It should be understood that the detailed description is merely illustrative of exemplary embodiments of the present application and does not limit the scope of the present application in any way. Like reference numerals refer to like elements throughout the specification.

In the drawings, the thickness, size, and shape of an object have been slightly exaggerated for convenience of explanation. The figures are purely diagrammatic and not drawn to scale.

It will be further understood that the terms "comprises," "comprising," "includes," "including," and/or "including," when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. Further, when a statement such as "… at least one" appears after the list of listed features, the entire listed feature is modified rather than modifying individual elements in the list.

As shown in FIGS. 1 to 3, the narrow-frame TFT light leakage prevention structure of the present invention comprises a TFT display module 2, a backlight module 5, and a FPC flexible printed circuit board 4, wherein the TFT display module 2 comprises an upper polarizer 2-2, an upper LCD 2-1, a lower LCD 2-3, and a lower polarizer 2-4 from top to bottom, A-1, A-2, A-3, A-4, and A-5 are several corners of the peripheral edge of the TFT display module 2, the backlight module 5 is attached to the back of the lower polarizer 2-4 at the lowest layer of the TFT display module 2, one end of the lower LCD 2-3 is connected to the FPC flexible printed circuit board 4, the backlight module 5 comprises a metal frame, the flat edges at the peripheral edge of the metal frame are all provided with a raised metal retaining wall 1, the raised metal retaining wall 1 is attached to the flat edges at the peripheral edge of the TFT display module 2, the display device has the advantages that the screen occupation ratio of the visible area 3 in the TFT display screen module 2 is high, the visual frame-free effect is achieved, the condition of light leakage of the frame of the TFT display screen module is also improved, and light is prevented from being emitted through the peripheries of the upper polaroid 2-2, the upper liquid crystal screen 2-1, the lower liquid crystal screen 2-3 and the lower polaroid 2-4 when a backlight source emits light to cause light leakage of the frame of the module. In this embodiment, the metal retaining wall 1 is made of SUS304, and is made of a hard material and cannot be well attached to each corner of the edge of the TFT display screen module, so that no metal retaining wall is arranged at each corner a-1, a-2, a-3, a-4, and a-5 of the edge around the TFT display screen module 2, and thus, the problem that the attachment degree of the metal retaining wall on the adjacent flat side is affected due to the fact that the metal retaining wall at the corner is not attached to the edge of the TFT display screen module is avoided, and light from penetrating through the upper polarizer 2-2, the upper liquid crystal screen 2-1, the lower liquid crystal screen 2-3, and the lower polarizer 2-4 due to careless attachment of the metal retaining wall on the straight side is prevented from leaking light of the frame of the module. The absorbance of the SUS304 material is only 1% -2%, which is far less than 20% of brightness loss caused by black dye, the brightness loss of the visible area can be ignored, and the high brightness effect of the product is ensured.
