Abstract

A liquid crystal displayer for preventing the generation of moisture includes a front cover, a touch panel, a nameplate, a partitioning plate and a liquid crystal displayer module. With the partitioning plate dividing a region between the touch panel and the liquid crystal displayer module into a first space and a second space, the first space is smaller, whereas the second space is larger. After the liquid crystal displayer module is supplied with electricity, the hot air staying in the first space is less. Further, the heat-obstructing effect of the partitioning plate causes the hot air not to condense in the second space, and thus it is not easy to generate a temperature difference from the external environment, thereby preventing the generation of mist.

Claims

1. A liquid crystal displayer for preventing generation of moisture, comprising:

a front cover having a frame body thereon, a back surface of the frame body being provided with an enclosing wall, an interior of the enclosing wall being formed with an accommodating space, the frame body further having an opening thereon, the opening being located in the enclosing wall, a front surface of the frame body being provided with a recessed connecting portion;

a touch panel arranged in the connecting portion, a periphery of the touch panel being provided with a side frame, the side frame being formed with a transparent region therein;

a partitioning plate arranged on the frame body within the enclosing wall;

a liquid crystal displayer module arranged in the enclosing wall in such a manner that the liquid crystal displayer module corresponds to and contacts one side face of the partitioning plate;

wherein with the partitioning plate dividing a region between the touch panel and the liquid crystal displayer module into a first space and a second space, after the liquid crystal displayer module is supplied with electricity, hot air generated will be dissipated away through a abutting portion between the liquid crystal displayer module and the partitioning plate, and thus the hot air does not condense in the second space, it is not easy to generate a temperature difference from the external environment, thereby preventing the generation of moisture.

2. The liquid crystal displayer for preventing the generation of moisture according to claim 1, wherein the front cover is made of a plastic material.

3. The liquid crystal displayer for preventing the generation of moisture according to claim 1, wherein the partitioning plate is made of a transparent plastic (PET).

4. The liquid crystal displayer for preventing the generation of moisture according to claim 1, wherein the partitioning plate is made of a transparent glass.

5. The liquid crystal displayer for preventing the generation of moisture according to claim 1, wherein a nameplate is arranged on the front surface of the frame body to correspond to the touch panel, a periphery of the nameplate is provided with a side frame, the side frame is formed therein with a perspective region.
