Problems solved by technology

Therefore, the conventional light-emitting display has a problem that the number of elements required to use the light-emitting display may be high
[0012] In addition, the aperture ratio of emissive displays may deteriorate due to the fact that one luminous control line is connected to each pixel row

Abstract

A light-emitting display, including: multiple scanning lines, multiple data lines, multiple first light-emitting control lines, multiple second light-emitting control lines, multiple third light-emitting control lines, and multiple pixels. Each pixel includes at least four light emitting elements, a driving circuit connected to and driving the light emitting elements, and a switch circuit assembly connected to the light emitting elements and the driving circuit for sequentially controlling the driving of the light emitting elements. The switch circuit assembly includes: a first switch circuit for sequentially driving the first and second light-emitting elements according to the first and second light-emitting control signals; and a second switch circuit for sequentially driving the first and second light-emitting elements according to the second and third light-emitting control signals third and fourth light emitting elements.

Description

[0001] This application claims priority from Korean Patent Application No. 10-2004-95977 filed in the Korean Intellectual Property Office on November 22, 2004, the entire disclosure of which is hereby incorporated by reference. technical field [0002] The present invention relates to a pixel circuit and a light-emitting display, and more particularly, to a pixel circuit and a light-emitting display using the same, the light-emitting display emits light through a plurality of light-emitting elements connected to one pixel circuit in order to improve the light-emitting display The aperture ratio (aperture ratio). Background technique [0003] In recent years, various display devices having reduced weight and volume compared with cathode ray tubes have been developed. In particular, light-emitting displays having good light emission, wide viewing angles, and high-speed response have been proposed as next-generation flat-type display devices. [0004] The light emitting elemen...
