Organic electroluminescence display device

Abstract

The present invention provides an organic electroluminescent display device capable of preventing deterioration of characteristics of a driving transistor included in a pixel and improving image quality. The device includes: a plurality of data lines; a plurality of gate lines; a plurality of pixels; a power supply line, each pixel of the display device includes: a first switch component, the first terminal is connected to the data line, and the second terminal is connected to the data line. The gate line is connected, and the data signal is output through the third terminal; the capacitor is connected to the third terminal of the first switch part, and is charged with the data signal; the second switch part is connected to the capacitor to the power line; the third a switching part connecting the capacitor to a ground terminal; a driving part having a first terminal connected to the power line and a second terminal connected to a third terminal of the first switching part through which the a current output of the power line; and an organic light emitting part connected to the third terminal of the driving part to emit light according to the amount of the current output.

Description

technical field [0001] The present invention relates to an organic electroluminescent display device, and more specifically, to an organic electroluminescent display device configured to prevent deterioration of characteristics and image quality of transistors included in each pixel. Background technique [0002] Currently, liquid crystal display devices are being developed as display elements to replace CRTs, and their usage rate is increasing. Since the liquid crystal display device is not a display device that emits light by itself, a light source of another route is required, and therefore, the power consumption is high, and there is a limitation in thickness reduction. Furthermore, since the liquid crystal display device obtains an image signal through the reaction of the liquid crystal, the response time of the liquid crystal has limitations in displaying high-speed moving images, and there is also a limitation in the viewing angle. As a display element replacing such...

Moreover, in the conventional organic electroluminescent display device, due to its high-speed response, the user recognizes the brightness corresponding to the intermediate value between the first frame and the second frame, and as a result, the display screen is slightly blurred.
