[INPp1-5L] An evaluation and reduction of the coupling noise in pen-based touch screen display
Keywords:touch screen display, AHVA, noise, Vcom compensation, passivation layer
Here we report the quantitative analysis of coupling noise in AHVA mobile display. Moreover, some approaches for reducing the coupling noise are demonstrated. The addition Vcom compensation circuit and moderate thickness of passivation layer is introduced to diminish the coupling noise.
