Description

Display screen for vehicular mirror surface streaming media

Technical Field

The utility model belongs to the technical field of digital image display, and particularly provides a low-power-consumption and low-heat-dissipation display screen for a vehicle-mounted mirror surface streaming media.

Background

The traditional analog signal transmission causes blurring, darkening, tailing and ghosting of images and unstable image display due to the influence of signal transmission distance, parameters of a transmission system and surrounding electromagnetic environment on signal quality, and brings a plurality of inconveniences to people.

The advent of vehicular streaming media technology has solved most of the above-mentioned technical problems. The vehicle-mounted streaming media in the prior art generally comprise a transparent glass cover plate, an optical adhesive layer, liquid crystal glass, a conventional polarizer and a backlight source which are sequentially arranged from top to bottom. However, with the increase of the consumer demand, the brightness requirement on LCM (vehicle streaming media) is higher and higher, so that the technical problems of greater and greater power consumption, more and more serious product heating, more and more difficult heat dissipation and the like of the vehicle streaming media are caused.

To sum up: in the prior art, the vehicle-mounted streaming media has large power consumption, serious heating and slow heat dissipation.

Disclosure of Invention

In view of the above, the present utility model aims to provide a low-power consumption and low-heat dissipation display screen for vehicular mirror streaming media.

In order to achieve the above purpose, the present utility model provides the following technical solutions:

the utility model provides a display screen for a vehicle-mounted mirror surface streaming media, which comprises a transparent glass cover plate, an optical adhesive layer, liquid crystal glass, a conventional polaroid and a backlight source, wherein the transparent glass cover plate, the optical adhesive layer, the liquid crystal glass, the conventional polaroid and the backlight source are sequentially arranged from top to bottom; wherein: and a reflective polarizer is arranged between the optical adhesive layer and the liquid crystal glass, and is attached to the CF surface of the liquid crystal glass.

The beneficial effects of the utility model are as follows: the VA area of the CG does not need mirror surface treatment, the transmittance of the CG is about 98%, and the LCM has mirror surface effect; when the TLCM finished product needs 1000cd/m 2, the brightness of LCM is 1020cd/m 2, so that the power consumption is greatly reduced, and the heat is reduced. Wherein CG is glass cover plate (cover glass), VA is visual Area (View Area), LCM is LCD display module, TLCM is full laminating LCD display module.

Additional advantages, objects, and features of the utility model will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the utility model. The objects and other advantages of the utility model may be realized and obtained by means of the instrumentalities and combinations particularly pointed out in the specification.

Drawings

For the purpose of making the objects, technical solutions and advantages of the present utility model more apparent, the present utility model will be described in the following preferred detail with reference to the accompanying drawings, in which:

FIG. 1 is a schematic diagram of the structure of the present utility model;

reference numerals: 1-glass cover plate, 2-optical adhesive layer, 3-liquid crystal glass, 4-conventional polaroid, 5-backlight source and 6-reflective polaroid.

Detailed Description

Other advantages and effects of the present utility model will become apparent to those skilled in the art from the following disclosure, which describes the embodiments of the present utility model with reference to specific examples. The utility model may be practiced or carried out in other embodiments that depart from the specific details, and the details of the present description may be modified or varied from the spirit and scope of the present utility model. It should be noted that the illustrations provided in the following embodiments merely illustrate the basic idea of the present utility model by way of illustration, and the following embodiments and features in the embodiments may be combined with each other without conflict.

Wherein the drawings are for illustrative purposes only and are shown in schematic, non-physical, and not intended to be limiting of the present patent; for the purpose of better illustrating embodiments of the utility model, certain elements of the drawings may be omitted, enlarged or reduced and do not represent the size of the actual product; it will be appreciated by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted. Furthermore, the present utility model may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed.

The embodiment of the utility model is shown in fig. 1, and the display screen for the vehicle-mounted mirror surface streaming media comprises a transparent glass cover plate 1, an optical adhesive layer 2, liquid crystal glass 3, a conventional polarizer 4 and a backlight source 5 which are sequentially arranged from top to bottom; wherein: a reflective polarizer 6 is arranged between the optical adhesive layer 2 and the liquid crystal glass 3, and the reflective polarizer 6 is attached to the CF surface of the liquid crystal glass 3. In this embodiment, the reflective polarizer 6 material itself is a multilayer composite structure (apf+tac+pva+tac+psa), in which a pressure-sensitive adhesive layer (PSA) can be directly attached to the CF side of the liquid crystal glass 3; the chinese name CF (Color Filter) in the CF side of the liquid crystal glazing 3 is color filter. The reflective polarizer 6 adopts the SLP-4205T5-P38L2-04 type and DF8-00001 type sold in the market; the conventional polarizer 4 adopts the SRKD41J-GRC# KZ type, ZT1-AG6-00002 type and ZT1-HC4-00001 type which are sold in the market.

Through experimental verification, the data comparison of the vehicle-mounted streaming media in the prior art and the display screen for the vehicle-mounted mirror streaming media is as follows:

as can be seen from the comparison of the tables, the same brightness of the finished product is achieved, and the display screen for the vehicle-mounted mirror surface streaming media can greatly reduce power consumption and heat.

Finally, it is noted that the above embodiments are only for illustrating the technical solution of the present utility model and not for limiting the same, and although the present utility model has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications and equivalents may be made thereto without departing from the spirit and scope of the present utility model, which is intended to be covered by the claims of the present utility model.
