Influence of user's demand on wide temperature and high brightness LCD screen

In recent years, due to the increasingly detailed requirements of users for LCD screens, wide-temperature LCD screens came into being.

Wide-temperature LCD refers to the LCD that can work in a wide temperature range. Wide-temperature LCD screen, also called active matrix LCD screen, can support normal operation between-20℃ and+70℃, and its application range for humidity is larger than that of general LCD screen.

The contrast and sharpness of the wide-temperature LCD screen are very good, forming a very smooth change and some major values, so that thebright image can play its related functions in a wide range of temperatures with the help of its relatively good current in the presence, and the whole product potential can be better obtained based on better transformation. Wide-temperature LCD has the characteristics of anti-vibration, anti-electromagnetic interference, stable picture quality and wide temperature range.

Wide-temperature liquid crystal display can be widely used in military affairs, telecommunications, electric power, metallurgy, machinery, numerical control, petroleum, chemical industry, medical treatment, transportation, instrumentation, aerospace and all kinds of field control and monitoring.When it comes to wide temperature LCD, I have to mention industrial LCD.

Wide temperature mode and working principle

New liquid crystal high and low temperature application technology, products can work normally at low temperature without heating or brightening.

The basic principle is as follows: the liquid crystal does not freeze or change its state at low temperature (-40℃); otherwise, neither the heating method nor the brightening method can work, so we think of using software to correct the drift of its electrical characteristics. Try to trigger the operation of the liquid crystal at low temperature. It is necessary to adjust the driving timing of liquid crystal and so on. Through a large number of experimental studies and extensive applications, this technology is very mature. No matter how the ambient temperature changes, the normal operation of the liquid crystal can be guaranteed by widening the trigger timing and matching the corresponding driving.

The front panel of industrial display is designed by aluminum wire drawing process, and the arc wrapping is harmonious; At the same time, the touch mode supports five-wire resistance and capacitance, and with the wide-temperature LED backlight LCD screen, the wide-temperature performance of the whole machine has passed the long-time controllable high-low temperature standard test. In addition, the reliability, environmental adaptability, real-time, expansibility, EMC compatibility and other performances of the whole machine are paid more attention to.

On the configuration, the RJ45 driver board developed by ourselves is adopted, which supports anti-dropping DC thread wide-voltage power supply (12V～24V) interfaces such as HDMI input, DVI input, VGA input interface, etc., and meets various application interfaces required by the site. At the same time, it also supports snap-in type, horizontal louver type, wall-mounted type, desktop type and other installation methods to unlock more application scenarios.

With the continuous improvement of technical level, industrial displays are getting better and better in terms of quality and stability, and the scope of their adaptability is becoming wider and wider. Industrial display manufacturers are also emerging one after another. SANYIN Technology has its own R&D team, and its products are constantly upgraded, which is worth your choice.
