Abstract

The utility model provides a TFT display screen, through set up the brace rod in TFT module casing periphery, support TFT module weight with the brace rod, the brace rod height sets up to unanimous with water gel thickness, make TFT module weight support by the brace rod, TFT has alleviateed the gluey pressure of box dam, the problem that box dam glue probably is collapsed has been solved, and box dam glue design width can narrow down, the quantity reduces, and can satisfy the narrow frame design of TFT module, and water gel thickness only needs to glue the width with the brace rod height unanimity, do not receive TFT weight and box dam glue the width influence, it is relatively stable, the yields obtains improving.

Description

TFT display screen

Technical Field

The utility model relates to a physics field especially relates to display screen technique in a poor light, especially a TFT display screen.

Background

In automobile electronic products, due to the requirements of automobile intellectualization and networking development, more and more information is required to be displayed on an instrument display screen and a central control display screen of an automobile, and the size requirement on the display screen is increased. The design of glass panels with integral black has become a trend in recent years. As shown in fig. 3 and fig. 1, the glass panel 1 is divided into an outer ink area printed with black ink and a transparent inner window area, and the screen of the TFT module 4 below can be seen through the inner window area, the black ink area has low reflectance and relatively black visual effect, and the glass panel 1 and the TFT module 4 cannot be completely attached to each other, and air exists in the middle. Therefore, the reflection rate is higher, the glass panel 1 is grey, and the glass panel has no good integral black effect, so that the problem is solved, a layer of optical glue is required to be filled between the glass panel 1 and the TFT module 4, no air exists between the glass panel and the TFT module, the reflectivity of a window area is reduced, the glass panel is black visually, and the integral black effect is good.

In the prior art, a glass panel is flatly placed on a tool, then a circle of box dam glue is coated on the periphery of an inner side window area, the width of the box dam glue is 1-2 mm, and a specific numerical value is determined according to the weight of a TFT module. The box dam glue is in a semi-solid state and needs to be cured through UV, water glue is coated in the middle of the box dam glue after the box dam glue is cured, the water glue is in a fluid state, and the range is limited through the box dam glue. And finally, the TFT module is placed on the dam adhesive and the water gel, the weight of the TFT module needs to be supported by the dam adhesive, the dam adhesive has a certain compression amount, and the thickness of the compressed dam adhesive is the thickness of the final water gel. Finally, the water gel is cured by means of heat curing. This kind of mode that supports the TFT module through box dam is glued has several problems, if the TFT module size is big, and weight is heavy, and box dam glue has the risk of being collapsed, perhaps in order to avoid being collapsed, needs the box dam to glue the width design and than wide, can lead to gluing the volume greatly like this to be unfavorable for the narrow frame design of TFT module. And secondly, the thickness of the water gel is ensured by the thickness of the compressed box dam gel, and is related to the weight of the TFT module and the width of the box dam gel, so that the control is difficult and the stability is poor.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to the above-mentioned defect among the prior art, provide a TFT display screen.

The main working principle is that the support ribs are arranged on the periphery of a TFT module shell, the support ribs are used for supporting the weight of the TFT module, and the height of each support rib is set to be consistent with the thickness of glue.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a TFT display screen, includes glass panels, box dam glue, TFT module, the box dam glue bond in one side surface of glass panels and constitute a sealed frame, the glue cover and bond in the surface of the glass panels in the sealed frame, the thickness of glue equals with the gluey thickness of box dam, wherein, the casing periphery of TFT module be provided with four at least brace rods, arbitrary one the brace rod highly all with the thickness of glue the same, the TFT module with box dam glue bond with the glue, the brace rod be located the TFT module with the glass panels between.

Furthermore, the shape of the supporting rib is a point shape.

Or the support ribs are strip-shaped.

Compared with the prior art, the utility model, its effect is positive and obvious. The utility model discloses TFT module weight is supported by the brace rod, has alleviateed the pressure of TFT to the box dam glue, has solved the problem that the box dam glue can be collapsed, and box dam glue design width can narrow down, and the quantity is reduced to can satisfy the narrow frame design of TFT module; and the thickness of the glue is only required to be consistent with the height of the supporting rib, the influence of the weight of the TFT and the width of the dam glue is avoided, the stability is high, and the yield is improved.
