Resistive Touch Screen for Sunlight Readability

For the past several years, the display industry has been focused on displays for sunlight readability. Recently, the demand for displays is not only sunlight readability, but with touch screen. Among all touch screen technologies available for sunlight readability, especially for low-cost and performance, resistive touch screen stands out. Resistive touch screen uses many ways for activation, such as fingers, pen, stylus, gloves, while other touch screen technologies limited to only a few. Each of these touch screen technologies has its benefits, but resistive touch screen has the benefits overlaps the benefits of the others.

Other important issues on touch screens are durability and sunlight readability. Recent advancement for resistive touch screen has achieved 94% optical clarity. Together with front surface hardness treatments and optical coating to minimize front surface reflection, resistive touch screen is ready to take on the challenges to become the major touch technology for outdoor applications - for crisp images and durability in hash environment and in direct sunlight.

The following are the main areas of considerations for touch monitors for use in outdoor.

1. Low reflection.

2. Touch screen durability

3. Finger-print resistant

4. Display brightness of 900 nits

5. Crisp images

6. Optical Bonding (bond touch screen onto the display)
