Embodiment Construction

[0013] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0014] Existing liquid crystal displays tend to respond slowly or even fail to display at low temperatures (≤-20°C). Therefore, a heater can be equipped with the liquid crystal display module to make the surface of the liquid crystal display module at extremely low temperature. The temperature can maintain the normal display temperature. The heater requires transparency, good heating uniformity and high heating efficiency in the AA (Active Area—Visible Area) area of ​​the liquid crystal display module.

[0015] Figure 2 to Figure 4 The ITO heater provided by the embodiment of the present invention is shown, including an ...

Abstract

The invention is applicable to a liquid crystal display, providing an ITO heater and a heating method of the liquid crystal display. The ITO heater comprises an ITO glass substrate which is provided with two opposite long edges and two opposite short edges, wherein, two opposite edges are electrically connected with connecting terminals along the direction from one edge to the other edge; and the ITO glass substrate is divided into a plurality of areas, each area is etched with an ITO pattern, and the ITO area of the etched edge part is larger than that of the central part. As for the ITO heater of the invention, the closer to the edge area, the stronger the resistance is; therefore, the heat output of areas closer to the edge is more than that of the central part, while heat of the edge is discharged fast, therefore, offset effect is achieved; the ITO heater can be used for the heating of liquid crystal display modules, and the temperature is evenly distributed on the surface of the ITO heater.

Description

technical field [0001] The invention relates to a heater and a heating method for a liquid crystal display, in particular to an ITO heater and a method for heating a liquid crystal display using the ITO heater. Background technique [0002] Liquid crystal display is a display device made by using liquid crystal molecules to change their optical properties under the action of an external electric field. It has many types and can be widely used in watches, calculators, instruments, notebook computers, small TVs and monitors, etc. . However, due to the viscous nature of the liquid crystal itself, existing liquid crystal displays tend to have slow response speeds or even display failures at low temperatures (≤-20° C.), thereby affecting display quality. [0003] To solve the above problems, see figure 1 , the prior art provides an ITO (indium tin oxide-indium tin oxide) heater, including ITO glass 11 and pins 12 . When in use, the above-mentioned heater can be arranged betwee...
