Active Matrix Display Devices and Electronic Devices having the Same
First Claim
1. An active matrix display device which comprises a plurality of pixels arranged in a matrix and a backlight source disposed at the backside of the matrix and emitting light to the matrix, wherein each of the pixels comprises:
- a liquid crystal element;
a driving controlling switch for controlling the driving of the liquid crystal element; and
a storage capacitor for storing image data provided to the liquid crystal element through the driving controlling switch;
wherein the display device further comprises;
a luminance detector for detecting luminance of the backlight source; and
a first voltage supplier, wherein according to the detected luminance of the backlight source, the first voltage supplier, in a sustain period of the image data, provides a predetermined voltage to a node of the storage capacitor which is opposite to a node of the storage capacitor coupled to the liquid crystal element.

Abstract
An active matrix display device is provided and includes a plurality of pixels arranged in a matrix and a backlight source disposed at the backside of the matrix which emits light to the matrix. Each pixel includes a liquid crystal (LC) element, a driving controlling switch, and a storage capacitor. The driving controlling switch controls the driving of the LC element. The storage capacitor stores image data provided to the LC element through the driving controlling switch. The display device further includes a luminance detector and a voltage supplier. The luminance detector detects luminance of the backlight source. According to the detected luminance, the voltage supplier, in a sustain period of the image data, provides a predetermined voltage to a node of the storage capacitor which is opposite to a node of the storage capacitor coupled to the LC element.
