Embodiment Construction

[0026] The basic idea of ​​the present invention is to deposit an electric heating pattern corresponding to the gate lines and data lines on the front of the substrate on the back of the TFT substrate through a patterning process, and the electric heating pattern is combined with the set control circuit and temperature sensor to heat the liquid crystal panel .

[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] figure 1 It is a schematic structural diagram of a liquid crystal panel supporting low-temperature display in the present invention, such as figure 1 As shown, it includes: a mating substrate 2 and a TFT substrate 3, and a liquid crystal layer between the mating substrate 2 and the TFT substrate 3 ( figure 1 not shown in ); the backlight 1 is incident from the back of the TFT substrate 3 . Wherein, the TFT substrate 3 includes: an electric heating pattern 31 , a TFT ...

Abstract

The invention discloses a liquid crystal panel supporting low-temperature display. The liquid crystal display panel comprises an involution substrate, a TFT (thin film transistor) substrate and a liquid crystal layer located between the involution substrate and the TFT substrate, and a TFT graph formed by grid lines and data is arranged on the front side of the TFT substrate. An electric heating graph corresponding to the TFT graph is arranged on the reverse side of the TFT substrate. The TFT substrate further comprises a control board arranged on the same side with the electric heating graph and a temperature sensor arranged on the side wall of the TFT substrate, and a control circuit on the control board is connected with the electric heating graph and the temperature sensor respectively.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal panel supporting low-temperature display. Background technique [0002] Since the liquid crystal panel is light, thin, and easy to carry, it has been widely used in various home TVs and portable electronic products. Common LCD panels can only work normally at room temperature, and general indoor workplaces can meet such display requirements. However, for a workplace in a cold climate or an extremely low temperature, the liquid crystal panel cannot work normally due to the abnormal deflection of the liquid crystal molecules in the low temperature environment. [0003] In order to solve the above problems, the following methods have been proposed to realize low-temperature liquid crystal display: [0004] 1) Add an electric heating element to the LCD panel, and heat the display through the control circuit. For example: heating the LCD panel by wra...
