B140XTK02.1 Replacement LCD screen

The AUO B140XTK02.1 is a 14.0 inch LCM (Liquid Crystal Module) screen, which uses amorphous silicon thin-film transistor liquid crystal display (a-Si TFT LCD) technology. The screen has a resolution of 1366 (RGB) × 768 pixels, providing a pixel density of 112 pixels per inch (PPI). The pixel arrangement is RGB vertical stripe, which means that each pixel consists of red, green, and blue subpixels arranged vertically in a stripe pattern.

The active area of the screen is 309.399 mm × 173.952 mm (H × V), and the outline dimensions are 315.9 mm × 197.54 mm × 3.2 mm (H × V × D). The screen has an antiglare, hard-coating (3H) treatment, which helps reduce reflections and scratches on the screen surface. The screen has a luminance of 220 cd/m² (Typ.), providing a decent level of brightness, and a contrast ratio of 400:1 (Typ.) (TM), which is lower than many other screens on the market.

The viewing angle for the screen is 45/45/15/35 (Typ.) (CR≥10), which means that the image quality starts to degrade when viewed from off-center angles. The screen has a response time of 8 (Typ.) (G to G) ms, which is a measure of how quickly the screen can change from one color to another. A lower response time results in less ghosting and blur in fast-moving images.

The B140XTK02.1 operates in TN (Twisted Nematic) mode, which is a common LCD technology that uses a twisted nematic liquid crystal to control light transmission through the screen. The screen has a 262K color depth and covers 44% of the NTSC color gamut, which is a measure of the range of colors that the screen can display.

The backlight of the screen uses white light-emitting diodes (WLED) and has a lifespan of 15,000 hours. The screen has an on-cell touch panel, which means that the touch sensors are integrated into the display, rather than being a separate layer. The screen uses an eDP (Embedded DisplayPort) interface with 1 lane and a 40-pin connector. The input voltage required is 3.3V (Typ.). The maximum storage temperature for the screen is -20 ~ 60 °C, and the maximum operating temperature is 0 ~ 50 °C.
