Description

Technical Field

[0001] The present application relates to a display device, and more particularly to a display device with a supporting element disposed on a frame. Background Art

[0002] For general automotive touch displays (such as digital instrument panels, car navigation displays, air conditioning control screens, digital rearview mirrors, etc.), double-sided tape can be used to fix the display panel assembly to the backlight module. However, if the adhesive tape is too wide, it will affect the visual taste, and if the width is too narrow, it will reduce the fixing force between components.

[0003] Currently, glue is used to replace double-sided tape for adhesion and fixing. However, glue requires a certain curing time. When the glue has not yet been completely cured, the product display device is offset due to external forces during the manufacturing process, making it impossible to move the product during the glue curing process. Therefore, shortening the curing time is an important issue. In addition, during the curing process, the product must be kept horizontal, otherwise the thickness of the cured glue will be uneven, resulting in poor parallelism between the display panel or touch screen and the backlight module, which in turn affects the display quality or touch accuracy. Summary of the invention

[0004] According to some embodiments of the present application, a display device is provided, comprising: a display panel group having a peripheral area; a backlight module comprising a frame; an adhesive material disposed between the peripheral area of ​​the display panel group and the frame; and a plurality of supporting elements disposed on the frame and in contact with the adhesive material.

Similarly, the area of ​​the first area is smaller than the area of ​​the second area, and the ratio of the area of ​​the first area to the area of ​​the second area is greater than or equal to about 3 / 4. In some embodiments, the first support element is disposed on the first portion 42a of the frame, adjacent to the second portion 42b of the frame, and the second support element is disposed at any location of the third portion 42c of the frame. The connecting line of the center point of the first support element and the center point of the second support element divides the area surrounded by the frame into a first area and a second area.

The connecting line of the center point of the first support element and the center point of the second support element divides the area surrounded by the frame into a first area and a second area. At this time, the area of ​​the first area is approximately the same as the area of ​​the second area, that is, the ratio of the area of ​​the first area to the area of ​​the second area is approximately 1 (i.e., greater than 3 / 4). In some embodiments, the first support element is arranged at the center point of the first part 42a of the frame, and the second support element is arranged at the center point of the third part 42c of the frame, and the first support element and the second support element are arranged oppositely. The connecting line of the center point of the first support element and the center point of the second support element divides the area surrounded by the frame into a first area and a second area. At this time, the area of ​​the first area is approximately the same as the area of ​​the second area, that is, the ratio of the area of ​​the first area to the area of ​​the second area is approximately 1 (i.e., greater than 3 / 4). In some embodiments, the first support element is disposed across the first and fourth portions of the frame in an L-shape, and the second support element is disposed across the second portion 42b and the third portion 42c of the frame in an L-shape.
