An imager is provided. The imager has an imaging platen which presents an imaging surface against which an object to be imaged can be placed. The imaging platen has a photodetector layer and a light guiding layer operable to guide light towards the object. The imager includes a light source operable to emit light into the light guiding layer. The light source is located at an edge of the light guiding layer, to guide light into the light guiding layer of the imaging platen.

Imaging device

A pixel driver circuit having only three conductive layers is described. The pixel driver circuit comprises a vertical driver transistor () spanning said three conductive layers, wherein a first of said conductive layers () on a first side of a middle conductive layer () provides a first source-drain connection () of said driver transistor, wherein a third of said conductive layers () on the opposite side of said middle conductive layer to said first conductive layer provides a gate connection () for said vertical driver transistor, and wherein said middle conductive layer provides a second source-drain connection () for said vertical driver transistor. The circuit also comprises a lateral switching transistor () with source-drain connections () in one of said three conductive layers. A dielectric layer () is provided between said first and second conductive layers and between said second and third conductive layers, and wherein semiconductor material () is provided spanning said first and second source-drain connections of said vertical driver transistor. A pixel display element () is coupled to said first source-drain connection of said vertical driver transistor.
