Backlight (BL)
In a general CRT screen, a high-speed electron gun is used to emit electrons and hit the phosphor on the silver light screen to generate bright light to display the picture. However, the LCD monitor itself can only control the brightness of the light passing through. The function of luminescence. Therefore, a backlit panel must be added to the LCD to provide a high-brightness light source with uniform brightness distribution. We can see in the above TFT LCD cross-sectional structure diagram that the main parts of the backlight panel There are lamps (cold cathode tubes), reflectors, light guide plates, prism sheets, diffusion plates, etc. Lamps are the main light-emitting parts, and the light guide plate distributes the light everywhere. The reflection plate restricts the light The residence is only moving in the direction of TFT LCD. Finally, with the help of prism sheet and diffuser, the light is evenly distributed to each area to provide a bright light source for TFT LCD. TFT LCD controls the liquid crystal by voltage Rotate to control the brightness of the passing light, thereby forming different gray levels.
Marine High Temperature Pressure Sensor
Product overview high temperature pressure sensor is a signal measuring element. The measured medium pressure is transmitted to the sensor through the heat dissipation structure on the transmitter. The high-precision signal processing circuit is located in the stainless steel shell to convert the sensor output signal into standard output signal. The whole product has undergone strict testing and aging screening of components, semi-finished products and finished products, with stable and reliable performance, so that the product can work stably for a long time when used for pressure measurement of high-temperature medium. Product features 1. 316L stainless steel isolation diaphragm structure 2. Imported high temperature resistant chip 3. Wide applicable medium temperature range 4. Strong anti-interference and good long-term stability 5. Direct contact with high-temperature medium to improve pressure response frequency 6. Provide rich pressure range of low pressure, medium pressure and high pressure
