Display devices and integrated circuits

Abstract

Integrated circuits, assemblies with integrated circuits, display devices and electrical circuits. There are various different aspects and embodiments of these apparatuses described herein. According to one aspect, a display device includes a plurality of display drivers which includes a serial shift register, wherein the display drivers are located in the display area of the display device which is viewable. According to another aspect, an integrated circuit, which has a plurality of functionally symmetric interface pads, includes an instruction decoder which decodes instructions received through at least one of the pads. In another aspect, an integrated circuit (IC) includes a position detector which detects a position of the IC relative to a receptor substrate and provides a signal which is determined by the position; this IC may be used in an assembly which includes the receptor substrate. In another aspect, an IC includes a position detector which detects a position of the IC relative to a receptor substrate and also includes a configurable pad which is configurable, depending upon the position as one of at least two of the following: an input pad, an output pad, or a no-operation pad. According to another aspect, a layout of an IC has a plurality of functionally symmetric interface pads wherein two such pads are configurable pads. According to another aspect, an assembly includes a receptor substrate and an IC attached to the substrate, and the IC includes a first logic circuit which provides a first function, a second logic circuit which provides a second function, and a selector which selects between the two functions such that the IC performs only the selected function. Other aspects and methods are also described.

Description

FIELD OF THE INVENTION [0001] The present invention relates to devices and methods for handling information, and more particularly, in certain embodiments, to display devices and also to other types of apparatuses such as integrated circuits with position detectors and other apparatuses. BACKGROUND OF THE INVENTION [0002] While the present invention has many aspects and embodiments, this section will focus on those aspects which relate to display devices. While there are a large number of various different types of display devices, one very common display device utilizes pixel electrodes to control a display medium such as a liquid crystal layer in order to create an image. These pixel electrodes may control other types of display media such as electrophoretic display media or organic light emitting diodes (OLED). Typically, a pixel electrode works by creating locally an electric field relative to another electrode. A display medium is sandwiched between the two electrodes and react...

AI Technical Summary

Problems solved by technology

While the foregoing display architecture works well generally for many types of applications, it is well known that manufacturing these displays is expensive due to poor yields when the size of the display is large.

Further, these displays are by necessity rigid as they are formed on glass and include layers such as polysilicon which are not flexible.

Further, the use of polysilicon to create the active backplane of the display means that the electrical characteristics of the display are inferior to single crystal silicon integrated circuits.
