Problems solved by technology

Therefore, the data driver 20 includes a plurality of data integrated circuits to have m output lines, which poses a problem of increased production cost
Specifically, as the resolution and size of the image display part 30 increase, the number of output lines of the data driver 20 also increases, thereby increasing the production cost of the LED

Embodiment Construction

[0028] Referring now to FIG. 2, the LED includes a scan driver 110, a data driver 120, an image display part 130, a timing controller 150, a demultiplexer module 160, a demultiplexer controller 170, and a data capacitor Cdata.

[0029] The image display part 130 includes a plurality of pixels 140 disposed adjacent to an area defined by a plurality of scan lines S1 to Sn and a plurality of second data lines DL including second data lines DL1 to DLm. Each pixel 140 emits light corresponding to a data signal transmitted through the second data line DL.

[0030] The scan driver 110 generates scan signals in response to scan control signals SCS supplied from the timing controller 150, and sequentially supplies the scan signals to the scan lines S1 to Sn. Scan driver 110 in a horizontal period 1H (as in Figure 4A The scan signal is supplied during the predetermined period shown in ).

[0031] One horizontal period 1H according to the embodiment of the present invention is divided...

Abstract

A light emitting display and its driving method using a demultiplexer to reduce the number of output lines of a data driver. The light emitting display includes a scan driver supplying a scan signal to a scan line, a data driver having output lines and supplying data signals to the output lines, a demultiplexer in each output line and supplying the data signal from each one output line to a number of data lines, an image displaying part including pixels formed in regions defined by the scan and data lines, and a capacitor coupled to each data line to be charged with a voltage corresponding to the data signal supplied to the data line. With this configuration, the number of output lines required in the data driver is reduced. Further, the voltages charged in the data capacitors are supplied to the pixels simultaneously, thereby displaying an image with uniform brightness.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 2004-67282 filed in the Korean Intellectual Property Office on Aug. 25, 2004, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to a light emitting display and a driving method thereof, and more particularly, to a light emitting display and a driving method thereof that reduce the number of output lines provided in a data driver by using a demultiplexer. Background technique [0004] Recently, due to the relative bulkiness of cathode ray tube (CRT) displays, various flat panel displays have been developed as a better alternative to CRT displays. Flat panel displays include liquid crystal displays (LCDs), field emission displays (FEDs), plasma display panels (PDPs), and light emitting displays (LEDs), among others. [0005] In flat panel displays, LEDs can emit light th...
