DISPLAY WITH REDUCED PARASITIC EFFECTS
First Claim
1. A display for an electronic device, the display comprising:
- a transparent layer having display elements mounted thereon and having a display side facing outwardly of the device; and
driver circuitry for the display elements;
wherein;
at least a portion of the driver circuitry is mounted on the display side of the transparent layer.

Abstract
Visual artifacts in a display are reduced by moving, to the extent possible, display driver components to the display surface itself, thereby shortening conductor distances and reducing the parasitic effects caused by parasitic resistance of the conductors between the display power supply and the display, and between the stabilizing capacitors and the display. To avoid interference with the device housing, low-profile driver components, including either or both of stabilizing capacitors and power supply terminals, can be provided and bonded to the surface of the display side of the outer layer of the display. Alternatively, the stabilizing capacitors can be formed on the display side in the same way that, e.g., in an LCD display, the transparent electrodes for controlling the liquid crystals are formed.
