Data control integrated circuit for liquid crystal display device, has selector to select output channels that supply pixel data to related data lines as per desired display resolution, and pins to create channel selection signal

摘要

#CMT# #/CMT# The device has a channel selector for selecting N data output channels of data integrated circuits (116) from multiple output channels. The N data output channels supply pixel data to a corresponding number of multiple data lines as per a desired resolution of a liquid crystal display. The selector has two option pins for generating a channel selection signal for determining the N data output channels. #CMT# : #/CMT# Independent claims are also included for the following: (A) a liquid crystal display device (B) a method of controlling a liquid crystal display device. #CMT#USE : #/CMT# Used for a liquid crystal display (LCD) device (claimed). #CMT#ADVANTAGE : #/CMT# The circuit allows to vary the number of channels as per desired resolution of the liquid crystal display screen with the help of the channel selection signals, such that the resolution of the display panel can be controlled by using a particular integrated circuit. The circuit can be used in a compatible manner independent of the resolution of the liquid crystal display screen. The circuit has reduced number of data integrated circuits, thus improving the operation of the display device and hence reducing the fabrication cost of the device. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# `(Drawing contains non-English language text)` The drawing shows a circuit diagram representing a liquid crystal display device.
