► LP140WFB-SPF1 is a 14.0-inch Full HD (FHD) LED LCD display
designed for Latitude 7400 (model P100G) laptops. It has On-Cell
touch function and uses a 40-pin eDP interface. This screen
combines high-definition image quality and touch function, and is
suitable for business office, remote conferencing, document
processing and multimedia applications. It is a high-quality panel
that combines practicality and modern interactive experience.
► The screen has a resolution of 1920×1080 (FHD), uses IPS
technology, and supports a 178° wide viewing angle, ensuring that
it can still present clear and color-accurate images when viewed
from different angles. LP140WFB-SPF1 has excellent color
performance, high contrast and moderate brightness, and is suitable
for various office and entertainment scenarios. Compared with
traditional TN panels, this IPS panel has obvious advantages in
color reproduction and viewing angle performance, especially in
tasks such as image editing, video playback and web design.
► 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. It is especially suitable for users who need touch
operation and high-definition display. For Latitude 7400 users with
damaged screens or who want to upgrade to a touch version, it is a
valuable choice. Before purchasing, be sure to confirm whether the
screen model, interface and touch function are fully compatible
with the notebook to ensure smooth installation and use.
