>> Study on large - size LCD low temperature heating based on multi - region 20th,Jan,2017
Liquid crystal display (Liquid Crystal Display, referred to as LCD) has a small size, light weight, low power consumption, electromagnetic compatibility, and other prominent advantages, has become the mainstream of the display device. As the liquid crystal molecules in the low-temperature environment, the viscosity coefficient increases, will lead to longer response time, the image has a serious tail, can not be properly displayed, resulting in widespread low-temperature LCD working performance is poor, not even work.
For the LCD in the low temperature environment can not work, the more way is to be coated with ITO (Indium Tin Oxides) film of glass as a heating element on the LCD low temperature heating compensation. When the current flows through the ITO film, ITO film itself, the heat generated by the resistance of the LCD to the fit, so that it meets the required temperature for normal work requirements. At present, the uniformity of temperature field of ITO heating method will decrease with the increase of LCD size, and the overheating or underheating will occur in some areas. In severe case, it will cause the breakdown of LCD and ITO heating elements.
In order to solve the above problems, the heating structure of multi-zone ITO film is used to control the duty cycle and introduce the feedback adjustment mechanism to control the heating rate of the heating element and optimize the temperature field distribution, so that the large-size LCD display can be started quickly in low temperature environment. Stable work.
