Embodiment Construction

[0029] Below, refer to the attached Figure 2 to Figure 7 Exemplary embodiments of the present invention will be described.

[0030] figure 2 A light emitting display device according to an embodiment of the present invention is shown.

[0031] refer to figure 2 , the light-emitting display device according to the embodiment of the present invention includes: a display area 300 including pixels 400 combined with scan lines S1 to Sn and data lines D1 to Dm; a scan driver 100 used to drive the scan lines S1 to Sn; a data driving part 200, used to drive the data lines D1 to Dm; the timing controller 500, used to control the scan driver 100 and the data driving part 200.

[0032] The timing controller 500 generates a data driving control signal DCS and a scanning driving control signal SCS in response to an externally provided synchronous signal. The data driving control signal DCS generated by the timing controller 500 is supplied to the data driving part 200 , and the scan...

Abstract

A data driver adapted to display an image with substantially uniform brightness is provided. The data driver includes a holding latch unit including holding latches for storing data, a signal generator including digital-analog converters for receiving the data to generate data signals, a first switching unit provided between the holding latch unit and the signal generator, and a second switching unit coupled to the signal generator to transmit the data signals to data lines. The first switching unit couples the holding latches to the digital-analog converters during a horizontal period in a manner different from the manner in which the holding latches and the digital-analog converters are coupled to each other during a previous horizontal period. Therefore, errors of the digital-analog converters are diffused so that it is possible to display an image with substantially uniform brightness.

Description

technical field [0001] The present invention relates to a data driver, a light-emitting display device using the data driver and a method for driving the light-emitting display device, more particularly, to a data driver suitable for displaying images with substantially uniform brightness, a A light-emitting display device using the data driver and a method for driving the light-emitting display device. Background technique [0002] Recently, various flat panel display devices (FPDs) that are lighter in weight and smaller in size than cathode ray tubes (CRTs) have been developed. The FPD includes a liquid crystal display device (LCD), a field emission display device (FED), a plasma display panel (PDP), and a light emitting display device. [0003] Among the FPDs, light emitting display devices display images using electroluminescence (EL) devices that generate light through recombination of electrons and holes. The light emitting display device ha...
