30-Pin vs. 40-Pin LCD Screens – What’s the Difference (#1805)
30-Pin vs. 40-Pin LCD Screens – What’s the Difference?
The pin count refers to the screen’s connector and determines compatibility. Most 30-pin screens are used for standard non-touch displays, while 40-pin screens are commonly required for touch, higher-resolution, or high-refresh-rate panels. Even if the size matches, the wrong pin type will not work, so always check your original connector before ordering.
