Industrial displays refer to displays used in industry. The industrial environment is more complex, so industrial displays have higher requirements than ordinary displays. For example, dust removal workshops need to be dust-proof, and vibration is more important to prevent vibration, and the stability is better, but for high and low temperature environments, a wide temperature display is required.
Wide-temperature industrial displays usually use low-temperature cooking for cooking, but this heating method sometimes causes difficulty in liquid crystal outflow or reduction during the Yajiu process, and there are other studies on heating at a single key point.
Heating
There are usually two methods of heating a little and heating the whole surface. The total power consumption of this display will increase by 4-6 times. For example, the power consumption of a 15-inch liquid crystal display at normal temperature (22°C) is 20ww, while the power consumption at a low temperature environment (-40°C) is 90-120w. This method is a heating method.
Brighten
There is also a way to achieve wide temperature, increase the brightness of the LCD screen, add a backlight tube, and use a special high-voltage rod (which can produce a starting voltage of 2000v-3000v) to illuminate in a low-temperature environment (-40°C) Backlight tubes, this method is used for two purposes, that is, to solve the problem of low-temperature operation of liquid crystals and the problem of visibility under sunlight, and this method is called a brightening method.
