Abstract

An integrated circuit for switching a pixel of the display. In one embodiment, an integrated circuit for switching a pixel is disclosed including first and second transistors is coupled between an analog input and the pixel. The first and second transistors provide a first and second digital select signals that are used to address the pixel.

Claims

1. An integrated circuit device, comprising:

a first transistor on a first substrate coupled between a first input and a first pixel of a display, the first transistor to couple the first pixel to receive an input signal from the first input in response to a first select signal;

a second transistor on the first substrate coupled between the first input and a second pixel of the display, the second transistor to couple the second pixel to receive the input signal from the first input in response to a second select signal; and

a third transistor on a second substrate coupled between a second input and the second pixel of the display, the third transistor to couple the second pixel to receive the input signal from the second input in response to the second select signal.

2. The integrated circuit device of claim 1 further comprising a fourth transistor on a second substrate coupled between the second input and a third pixel of the display, the fourth transistor to couple the third pixel to receive the input signal from the second input in response to a third select signal.

3. The integrated circuit device of claim 1 wherein the first input is on the first substrate and the second input is on the second substrate.

4. The integrated circuit device of claim 1 wherein the the first and second pixels are included on a third substrate, the first and second substrates mounted on the third substrate.
