Gossly Transpent LCD Screen Custom Prototype Membrane Keyboard
Original Manufacturer In China
An LCD window membrane switch is a type of input device that
combines a membrane switch with a transparent window or cutout to
allow for the integration of an LCD (Liquid Crystal Display)
screen.
Key characteristics of an LCD window membrane switch include:
Membrane Switch Structure:
The basic construction of an LCD window membrane switch follows the
typical membrane switch design.
It consists of multiple layers, including a top protective layer, a
membrane switch layer, and a printed circuit board (PCB) layer.
LCD Window:
The top protective layer of the membrane switch features a
transparent window or cutout that exposes the underlying LCD
screen.
This window allows the LCD screen to be visible and accessible to
the user.
LCD Integration:
An LCD display is integrated into the membrane switch assembly,
typically positioned behind the transparent window.
The LCD screen can be used to display information, graphics, or
user feedback related to the switch functions.
