Heater as well as shaped liquid crystal display with same and heating method thereof

Abstract

The invention discloses a heater applied to a shaped liquid crystal display and a heating method thereof, and the shaped liquid crystal display with the heater and a heating method thereof. The heater is in a pentagonal structure with a first edge, a second edge, a third edge, a fourth edge and a fifth edge, which are connected end to end in order; the first edge is parallel to the third edge; the second edge is parallel to the fifth edge; and the first edge, the second edge and the fourth edge are longer than the third edge and the fifth edge. The heater is provided with first, second and third electrodes, first, second and third conductive silver pastes, first, second and third cupronickel sheets, first, second and third temperature sensors, and first, second and third electrode lead wires, wherein the first, the second and the third electrodes are respectively fixedly arranged at the first edge, the second edge and the fourth edge; the first, the second and the third conductive silver pastes are respectively fixed at the first, the third and the fifth edges; the first, the second and the third cupronickel sheets are respectively fixed on the first, the second and the third conductive silver pastes; the first, the second and the third temperature sensors are respectively fixed at the first, the second and the fourth edges; and the first, the second and the third electrode lead wires are respectively leaded out from the first, the second and the third cupronickel sheets. The heater provided by the invention has the advantages in that energy can be uniformly distributed on the shaped liquid crystal display, so that the display has good display effect at a low temperature.

Description

technical field [0001] The invention belongs to the field of liquid crystal displays, and in particular relates to a heater applied to a special-shaped liquid crystal display and a heating method thereof, a special-shaped liquid crystal display with the heater and a heating method thereof. Background technique [0002] When the working temperature of the liquid crystal display module is low, the viscosity of the liquid crystal increases due to too low temperature, and the electro-optic effect weakens or disappears, which causes the liquid crystal display module to show a decrease in brightness, lightening of the screen color, and prolonged image response time. Usually the liquid crystal display module is a regular cuboid or cube, so the general design adopts placing electrodes on both sides of the heater to complete the heating process. [0003] However, in some specific conditions and special occasions, liquid crystal display modules with irregular shapes are often used. F...

AI Technical Summary

Problems solved by technology

For such a special-shaped liquid crystal display module, the design of the heater cannot be carried out according to the conventional method when heating at low temperature.

If the design is unreasonable, it will lead to energy accumulation in a certain area of ​​the LCD screen, not only can not be uniformly heated, but also the screen may burst due to excessive energy in a certain area
