Description
Technical Field

Background
In the field of liquid crystal displays, there are some special fields that require the liquid crystal displays to be able to operate at-40 ℃ or even-50 ℃. However, since the lcd is limited by the characteristics of the liquid crystal molecules, the display screen may have severe gray-white and smear at low temperature, which seriously affects the display effect and causes the lcd not to be used normally. Therefore, the liquid crystal display needs to be subjected to heating temperature-raising treatment. At present, the common practice is to add an electric heating glass on the surface of the liquid crystal screen, the electric heating glass leads out two wires, and the electric heating glass applies voltage to the wires, so as to generate heat to heat the liquid crystal screen. Such a treatment has the following problems:
(1) in order to weld a lead on the electric heating glass, copper foil is required to be adhered on the glass in advance, and then the lead is welded on the copper foil, so that the resistance between two electrodes is increased, the heating power is insufficient, and the required temperature rise cannot be achieved within a specified time;
(2) because the glass can not bear high temperature, the glass is easy to crack because the welding temperature is as high as 400 ℃ during welding;
(3) due to the fact that only one welding spot is arranged, the lead is easy to fall off in the assembling process;
(4) in order to meet the requirement of larger heating power consumption, the size of the lead needs to be large enough, so that the bonding distance between the heating glass and the liquid crystal display is larger, and when the bonding glue layer is thicker, bubbles and other defects are easily generated;
(5) for the electric heating glass with larger size, the lead is welded at the edge of the glass, so that the heating effect of the whole glass is uneven, the heating efficiency is influenced, and even the glass is broken.
