Problems solved by technology

However, in portable electronic devices, the trend of display device size design is lighter and thinner, and the internal space is very limited, so it is not easy to add additional heating wires and circuits for driving the heating wires.
Moreover, the power of portable electronic devices is supplied by batteries, and the requirements for low power consumption are getting higher and higher. The use of heating wires will increase additional power consumption, which does not meet the requirements of portable electronic devices.

Abstract

The invention provides a radiating buffer device and a display device. The radiating buffer device is arranged between a display panel and a protective plate, the radiating buffer device defines a dustproof region, light rays output by the display panel pass through the dustproof region, a first section of the radiating buffer device comprises a plurality of layers of first buffer materials, the layers of first buffer materials are arranged along the width direction of the radiating buffer device, each first buffer material is provided with at least one first venthole penetrating along the width direction of the radiating buffer device, the first ventholes of two adjacent layers of the first buffer materials are staggered, and a first ventilation gap is arranged between two adjacent layers of the first buffer materials. According to the radiating buffer device and the display device in the embodiment of the invention, hot airflow inside the dustproof region can be discharged outside the dustproof region through an airflow channel, thereby preventing the condensation of the hot airflow on the inwall of the protective plate, and further preventing the occurrence of mists without adding additional size and power consumption.

Description

technical field [0001] The present invention relates to the technical field of displays, and in particular, to a heat dissipation buffer structure and a display device. Background technique [0002] The structure of the current flat panel display device is usually as follows figure 1 As shown, a display panel 2 is arranged inside the casing 1, and the backlight module 3 projects light to provide backlight for the display panel 2. An image can be formed on the display panel 2, and is exposed through the opening 1a on the front side of the casing 1 for use. viewers to watch. In order to protect the display panel 2 and maintain the airtightness of the casing 1 , the opening 1 a of the casing 1 is covered with a transparent tempered glass plate 4 to protect the display panel 2 from being damaged. [0003] For electronic equipment, moisture often causes serious damage, such as short-circuiting the circuit or causing corrosion of electronic components. Although the housing 1 in ...
