Exact replacement panel

This 14 inch display matches part number LP140WFB(SP)(K4) and installs directly into laptops that specify the same model. The 40 pin connector and touch capability align with the original hardware so the repair restores full input and video function.

300 cd/m² brightness and 60 Hz refresh

The panel reaches 300 cd/m² with a 700:1 contrast ratio at 60 Hz, delivering consistent output for everyday tasks. Normal operation produces no audible noise and the component draws only the power allocated by the host laptop's display subsystem.

Touch layer and 40 pin cable included

The integrated touch sensor works immediately once the flat cable seats in the motherboard socket. No separate driver disc or calibration utility ships with the screen; the operating system handles touch input through its standard HID stack.

Questions about this item

How do I route the 40-pin video cable when installing the LP140WFB panel?

Connect the 40-pin connector to the motherboard header, then secure the panel with the original mounting brackets. The step most people miss is re-attaching the touch-screen flex cable to the small ZIF socket beside the hinge.

Which part will need replacement first on the LP140WFB?

The LED backlight ages before the liquid-crystal layer; after several years the 300 cd/m² brightness can drop noticeably, so the backlight assembly is the typical long-term swap.

At what refresh rate does the LP140WFB hit its motion-clarity limit?

The panel is specified at 60 Hz, so sustained fast motion will show blur once frame rates exceed that 60 Hz ceiling.
