You should define the LCD dimension first. This should be your first step. Of course, this depends on your End product dimension and the display request.
When you defined the LCD dimension, you need to decide what kind of resolution you need.
LCDs have many kinds of resolution. For example, a 7inch LCD has 800*480, 1024*600, and 1280*800 resolution (three kinds of resolution). Generally speaking, a Higher Resolution will cause a higher price.
When you’re deciding what LCD brightness you need, you should be taking into account if your product will work outdoors. In that case, you’ll need higher brightness LCD.
After you define your LCD dimension, you should define what kind of touch panel is required.
We have resistive touch and capacitive touch panels. For most kinds of usage, capacitive touch works much better than resistive touch.
Capacitive touch supports Multi-Point touch. Furthermore, it’s stronger than resistive touch panels, which will be scratched after some time, and a capacitive touch panel is suitable for Android slide operation.
Very few usages will need resistive touch only: If your end product will be in contact with water frequently or your end product work in special Electro-Magnetic field, resistive touch will have higher reliability than capacitive touch.
If you don’t need an LCD display with a touch panel, just the main board, please contact us, we can also sell the main board independently.
