7.02" TFT 1200*1920 dots with RTP product introduction
TXW702002B0 is a 7.02-inch 16:10 aspect ratio full-color TFT LCD display with a resolution of up to 1200 * 1920 and IPS full view high-definition high brightness display effect. This TFT display supports MIPI interface. With the help of anti glare display surfaces, the screen does not reflect light and maintains better image quality.
The contrast ratio of this module is 500:1 (typical value), and the brightness is 1500-2000 nits (typical value). The power supply voltage range of LCM is 21.5-25.6V, and the module operates in the temperature range of -20 to+70 ℃, with storage temperature between -30 to+80 ℃.
This product is widely used in fields such as drone remote control panel display, photography equipment, military display equipment, industrial security, medical equipment, handheld PDAs, etc.
