Samsung developing smaller, brighter touch-screens
Samsung is developing a new display chip that promises smaller and brighter touch-screen LCD panels. The mobile display driver IC makes the LCD panel itself touch sensitive and eliminates the need for a separate touch screen panel.
The new panel integrates the touch-sensitive portion directly onto the LCD display pixel. Previously touch screens needed an extra touch sensitive layer that was placed on top of the display panel. Those screens also needed a separate readout chip.
The new panels could be up to 10% brighter and 25% thinner because there is no extra touch panel layer needed.
