CPT CLAA121UA02CW is a slim 12.1-inch HD+ TN TFT LCD panel with 1600×900 resolution and dual-channel LVDS interface, optimized for compact embedded industrial terminals, portable test equipment and lightweight HMI devices. Equipped with integrated WLED backlight with built-in driving circuit, it eliminates extra inverter modules and delivers steady 250 cd/m² brightness with low power consumption for long-duration 24/7 operation. Its ultra-thin 4.45mm outline thickness greatly saves internal assembly space for small-size all-in-one industrial machines and portable inspection instruments. The matte anti-glare front surface effectively weakens ambient light reflection in indoor factory and laboratory environments, while the 2H hard coating prevents minor surface abrasion during daily equipment use. Standard dual 6-bit LVDS signal provides reliable anti-interference transmission, widely compatible with mainstream embedded motherboards, single-board computers and industrial display driver boards without complex signal conversion. Operating within 0℃~+60℃ standard industrial temperature range, this original CPT panel is fully RoHS compliant and supplied with full factory optical aging test for light industrial automation, portable measuring equipment and legacy screen replacement projects.
