Problems solved by technology

As the load of the circuit in the border area of ​​the display panel increases, the heat generated by the corresponding circuit also increases. The more heat generated may cause the phase change of the liquid crystal, and different heat distributions between the border area and other areas, as well as flickering, Problems such as wrong screen and different pictures
Although the existing heat dissipation structure can dissipate heat to a certain extent in the frame area, the heat dissipation effect is not good.

Embodiment approach

[0064] Specifically, the frame area 212 is arranged in a ring around the display area 211 to wrap the display area 211 . At this time, the first heat dissipation part 11 is also arranged in a ring to realize the overall heat dissipation of the frame area 212 . Certainly, it is also possible to only arrange the second heat dissipation portion 12 in an annular shape, and only dissipate heat through the second heat dissipation portion 12 . In such an embodiment, the thermal conductivity of the second heat dissipation portion 12 may be greater than that of the first heat dissipation portion 11 , thereby achieving a better heat conduction effect.

[0065] More specifically, the first heat dissipation portion 11 and the second heat dissipation portion 12 may both be arranged in a rectangular shape and match the shape of the frame area 212 . It should be understood that figure 2 The view of the heat dissipation structure 10 shown in , is a view at an angle other than 90° to the plane...

Abstract

The invention discloses a heat dissipation structure and a display device. The heat dissipation structure is used for the display device, the display device comprises a display panel, and the display panel is provided with a display area and a frame area located on the periphery of the display area. The heat dissipation structure comprises a first heat dissipation part which is arranged on the non-display side of the display panel and is in contact with the frame area, and the first heat dissipation part is provided with a containing groove; the second heat dissipation part is arranged in the containing groove and makes contact with the frame area, and the heat conductivity coefficient of the second heat dissipation part is different from that of the first heat dissipation part. Therefore, the heat dissipation structure provided by the invention can dissipate heat through the heat dissipation parts with different heat conductivity coefficients, and can dissipate heat of different heating parts in a targeted manner, thereby achieving a good heat dissipation effect.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a heat dissipation structure and a display device. Background technique [0002] With the development of photoelectric display technology and semiconductor manufacturing technology, thin film transistor liquid crystal display (Thin Film Transistor-Liquid Crystal Display, referred to as TFT-LCD) has become the current flat-panel Display mainstream technology, widely used in home appliances, computers, transportation, medical and other fields. [0003] The display panel has a display area and a frame area around the display area, and the frame area is designed with dense driving circuits. As the load of the circuit in the border area of ​​the display panel increases, the heat generated by the corresponding circuit also increases. The more heat generated may cause the phase change of the liquid crystal, and different heat distributions between the border area and other a...
