Description

display device

technical field

The present invention relates to a display device, and in particular to the design of the fixing structure of the backlight module in the display device.

Background technique

With the vigorous development of the optoelectronic industry, liquid crystal display (liquid crystal display; LCD) has been widely used in various notebook computers (notebook), personal digital assistant (personal digital assistant; PDA) and mobile phone (cell phone) and other electronic devices. However, the liquid crystal display device is a non-self-illuminating flat panel display, which needs to be illuminated by an external light source. Therefore, a display device is used as a light source in a liquid crystal display device, and the high-brightness and high-uniformity illumination of the display device enables the liquid crystal display device to efficiently display high-quality images.

Please refer to Fig. 1 and Fig. 2, which are schematic cross-sectional diagrams 1 and 2 of an existing liquid crystal display device. It can be known from the figures that the liquid crystal display device 10 is mainly composed of a frame 11, a backlight module 12 and a display module 13. The backlight module 12 and the display module 13 are sequentially arranged in the frame 11, and the backlight module 12 at least includes components such as a light guide plate 121, an optical film group 122 and a light source (not shown in the figure), wherein when the backlight module 12 is assembled, each component The adhesive tape 14 is often used as a fixed component for the assembly and fixation of the space. For example, please refer to FIG. 121 and the friction between the frame 11, to prevent the problem of abnormal sound caused by friction. For another example, referring to FIG. 2 , an adhesive tape 14 can also be used to fix between the optical film set 122 and the light guide plate 121, so as to prevent the optical film set 122 from sliding on the light guide plate 121, and further avoid scratching the optical film due to sliding. The film set 122 and the light guide plate 121 .

However, the above-mentioned traditional fixing method requires a large number of tapes. Please refer to FIG. 3, which is a schematic diagram of the use of tapes for the backlight module of an existing liquid crystal display device. Between the optical film group 122 and the light guide plate 121, a At least one adhesive tape 14 is used to fix the light guide plate 121 and the frame 11. When the light guide plate 121 is fixed to the frame 11, multiple adhesive tapes 14 are used for fixing. When the number of adhesive tapes is more, each additional adhesive tape will increase the relative cost. The additional man-hours and material cost will increase the manufacturing cost of the display device, and the competitiveness of the product will be insufficient.

Contents of the invention

In view of the problems in the prior art, the purpose of the present invention is to provide a display device, which solves the above problems by using the structure of the backlight module and the design of the adhesive member (tape).

The present invention proposes a display device. The display device in the embodiment includes a frame, a light guide plate, an optical film group, a display panel, and an adhesive member, wherein the frame has a bearing part, and the bearing part has at least one groove, and the guide The light plate is arranged in the frame, and is located under the bearing part, and the optical film group is arranged on the light guide plate, and the optical film has at least one lug part, and extends into the groove. In addition, the display panel is also located in the frame. Inside, and set on the bearing part.

As mentioned above, the carrying part is used to fix the display panel, and the adhesive part is used to fix the light guide plate and the optical film group, so the adhesive part is arranged between the light guide plate and the carrying part, and the adhesive part spans The groove extends below the optical film group, in other words, the part of the adhesive part is adhered between the light guide plate and the bearing part, while the other part of the adhesive part is the part across the groove, and is adhered to the optical film group and the light guide. Between the light plates, the optical film group can be fixed on the light guide plate.

Through the above-mentioned structure, plus the design that the adhesive part is a single continuous adhesive tape, which is arranged between the light guide plate and the bearing part, and at the same time spans the groove to extend below the lug part, the utilization can be realized. One adhesive piece can simultaneously fix the optical film group on the light guide plate and fix the light guide plate under the bearing part, which not only reduces the number of adhesive pieces (tape) used, but also shortens the assembly time. Relatively, the manufacturing cost It can also be reduced to make the product more competitive.

In order to make the purpose, features and advantages of the present invention easier for those skilled in the art to understand, a preferred embodiment is described below in detail together with the accompanying drawings.
