7" TFT 1024*600 dots product introduction
Model No. : TXW700028N0
TXW700028N0 is a 7-inch TN transmissive color active matrix TFT LCD
display with a resolution of 1024 * 600 dots. The module size is
164.9 (width) X 100 (height) X 3.5 (depth) mm; Effective area
154.21 (width) X85.92 (height) mm. This TFT monitor supports a 24
bit RGB 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 800 nits (typical value). The power supply voltage
range of LCM is 8.9-10V, with a typical value of 9.5V. This module
operates within a temperature range of -30 to+85 ℃ and stores
temperatures between -30 to+85 ℃.
