Problems solved by technology

In addition, since there is not enough time to transfer the stored data signal to the pixel P 1mk , so the charge corresponding to the data signal is not transferred to the pixel P 1mk
As a result, the organic light emitting display device does not emit light having a luminance corresponding to the supplied data signal, and thus, the display quality is poor.

Embodiment Construction

[0033] Embodiments will now be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown.

[0034] image 3 is a schematic diagram of an organic light emitting display device according to an exemplary embodiment of the present invention.

[0035] refer to image 3 ,according to image 3 The organic light emitting display device of the embodiment includes a pixel part 100 , a scan driver 200 , an emission driver 300 , a data driver 400 , a demultiplexer unit 500 , a data line selector 600 and a timing controller 700 .

[0036] In synchronization with a scan control signal Sg (ie, a start pulse and a clock signal) provided by the timing controller 700, the scan driver 200 supplies a plurality of scan lines S 1 -S 2n Scan signals are supplied sequentially.

[0037]The transmit driver 300 may include a shift register to output a transmit control signal in synchronization with a control signal (ie, a...

Abstract

The invention discloses an organic light emitting display device with a demultiplexer and a method for operating the organic light emitting display device. In the organic light-emitting display device, each pixel column is provided with two data lines, and each data line is connected to the odd-numbered or even-numbered pixels of the column. Accordingly, a data signal may be supplied to one of the data lines during one scan period, and transmitted to a corresponding pixel during a next scan period. Thus, the driving time is reduced because the data driver only drives half of the pixels of the column.

Description

technical field [0001] The present invention relates to an organic light-emitting display device, and more specifically, to such an organic light-emitting display device: a demultiplexer uses double data lines to provide data signals to ensure sufficient time to provide data signals to the data lines, And transmit the data signal to the pixel. Background technique [0002] Since flat panel displays (FPDs) can be made smaller and lighter than display devices using cathode ray tubes (CRTs), considerable research has been conducted on FPDs in recent years. Among FPDs, organic light-emitting display devices have attracted great attention as next-generation FPDs due to their excellent light emission and viewing angle characteristics. [0003] Unlike a liquid crystal display device (LCD), an organic light emitting display device does not require an additional light source but uses light emitting diodes that emit light of a specific color. The light emitting diode emits light wit...
