► The biggest feature of LP140WFB-SPF1 is that it supports **On-Cell Touch** technology. Unlike traditional external touch layers, On-Cell Touch embeds the touch sensor directly into the liquid crystal layer, thereby reducing the thickness of the screen and improving the sensitivity and accuracy of the touch. This integrated design not only makes the screen look thinner and simpler, but also greatly reduces light reflection and thickness, improving the overall touch experience and visual effects.
► The screen uses a 40-pin eDP (Embedded DisplayPort) interface, which supports high-speed data transmission and can meet the stability and bandwidth requirements of high-resolution touch panels. This interface is widely used in mid-to-high-end notebook computers. While ensuring image quality, it also effectively reduces power consumption and improves battery life.
► In addition, this model screen supports LED backlight technology, which has good energy saving and brightness performance. The typical brightness range is 250~300 nits, which can maintain good readability in a variety of lighting environments. The surface is made of glossy glass, which enhances the visual texture and improves touch sensitivity. However, there may be some reflection under strong light, so it is recommended to use it with anti-glare film.
► In terms of installation, LP140WFB-SPF1 adopts an ultra-thin structure and is suitable for the fixing method of the original screen of Latitude 7400, without additional modification. When replacing, just pay attention to the interface and cable direction consistent with the original screen to achieve seamless docking.
► In summary, LP140WFB-SPF1 is a notebook LCD display with excellent performance, integrated touch, and good visual experience.
