Abstract

An anti-fogging display screen comprises a display module (1), a protective plate (2), a dryer (3) and an inflation device (4). The display module (1) is equipped with a bezel (5). The protective plate (2) is arranged on the bezel (5). An inner cavity (10) is formed among the display module (1), the bezel (5) and the protective plate (2). An air inlet (50) in communication with the inner cavity is disposed on the bezel (5), the protective plate (2) or the display module (1), and an air outlet (51) in communication with the inner cavity is disposed on the bezel (5), the protective plate (2) or the display module (1). The inflation device (4) is connected to the dryer (3), and the dryer (3) is in communication with the air inlet (50). The inflation device of the anti-fogging display screen takes in external air, and the external air forms dry air after passing through the dryer. The dry air enters the inner cavity through the air inlet and is discharged from the air outlet. The inner cavity has continuously-flowing dry air, thus effectively reducing the dew point of the inner cavity to avoid dew condensation on an inner surface of the protective plate, and the problem of water fog covering the display module image on the protective plate can be thoroughly solved to ensure the performance of the product.

detailed description

The embodiments of the present invention are described in detail below:

As shown in FIG. 1-2, the anti-fog display screen of the embodiment includes a display module 1, a protection board 2, a dryer 3, and an inflator 4. The display module is provided with a frame 5, and the protection is provided. The plate 2 is disposed on the frame 5, and the inner cavity 10 is formed between the display module 1, the frame 5 and the protection plate 2. The frame 5 is provided with an air inlet 50 communicating with the inner cavity 10, and the frame 5 is disposed on the frame 5. A venting opening 51 is provided in communication with the inner chamber 10, and the inflator 4 is connected to the dryer 3, which is in communication with the air inlet 50. In the above anti-fog display screen, the inflator 4 draws in outside air, and the outside air passes through the dryer 3 to form dry air. The dry air enters the inner cavity 10 through the air inlet 50 and is discharged from the exhaust hole 51, and the inner cavity 10 has continuous The flowing dry air effectively reduces the dew point of the inner chamber 10, preventing condensation on the inner surface of the protective sheet 2. The anti-fog display has a simple structure, and can completely solve the problem that the water mist on the protection board 2 blocks the image of the display module 1 and ensure the use performance of the product.

It should be noted that the air inlet hole 50 may also be disposed on the protection board 2 or the display module 1 , and the air outlet hole 51 may also be disposed on the protection board 2 or the display module 1 , but based on the convenience of processing.
