DCL230830 is a custom 2.1“ VATN LCD module produced by our company. The LCD is VA type TN, negative, transmissive. The logic voltage of this module is , and backlight voltage is 3V. We assigned 3 white LEDs to enhance the backlight brightness, to make sure the contrast ratio and definition is higher than common TN LCD. The operating temperature range of this module is -20°C to 70°C and storage temperature range is -30°C to 80°C. This is a full view LCD, in the video, you can see the images clearly in any directions. Now, we will introduce some knowledge about VATN for you. VATN LCD Display (Vertically Aligned Twisted Nematic) is just another type of LCD (liquid crystal display) module but with a high contrast ratio of 1000 to 1. It is a negative mode display with a transmissive polarizer. In VATN LDC Display liquid crystals naturally align vertically to the glass substrates. When no voltage is applied, the liquid crystals remain perpendicular to the substrate, creating a black display between crossed polarizers. When voltage is applied, the liquid crystals shift to a tilted position, allowing light to pass through and create a gray-scale display depending on the amount of tilt generated by the electric field. Q：What are the advantages of VATN LCD Display? A： 1. High contrast ratio (1000:1) 2. Deeper-black background 3. Wider view angle compared to TN (Twisted Nematic) 4. Wide operating temperature (-40°C ~ 85°C) Q：What are the major applications of VATN LCD Display ? A：Due to its high contrast ration, VATN is a popular choice of display is industrial application as well as home appliances: 1. White Goods 2. Automotive 3. Medical Application 4. POS Machine 5. Wearable Device That’s all for today. Thanks for watching. See you next time.
