Embodiment Construction

[0022] In the following detailed description, only certain exemplary embodiments of the present invention have been shown and described, simply by way of illustration. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention.

[0023] Accordingly, the drawings and description are to be regarded as illustrative in nature and not restrictive. There may be cases where components shown in the figures or components not shown in the figures are not discussed in the specification because they are not necessary for a complete understanding of the invention. Like references refer to like elements throughout. Phrases such as "one body is connected to another body" can mean "the first body is directly connected to the second body" or can mean "the first body is connected with a third body placed between the first body and the second body". electrically connecte...

Abstract

A display includes a display area having a plurality of data lines for transmitting a data signal representing images and a plurality of pixel circuits coupled to the plurality of data lines. The display also includes a plurality of first signal lines, a data driver coupled to the plurality of first signal lines for time-dividing a first signal corresponding to the data signal and transmitting the time-divided first signal to the plurality of first signal lines, and a demultiplexer for demultiplexing the time-divided first signal transmitted from the plurality of first signal lines to generate the data signal, and applying the data signal to at least two first and second data lines of the plurality of data lines One field has first and second subfields The demultiplexer applies the data signal to the first data line for a first period of the first subfield, and applies the data signal to the second data line for a second period of the second subfield, and the first signal is set corresponding to at least two colors.

Description

technical field [0001] The present invention relates to a demultiplexer and a display using the demultiplexer, in particular to a demultiplexer for demultiplexing data currents. Background technique [0002] Generally, an organic light emitting diode (OLED) display that emits light by electrically exciting a fluorescent organic compound displays an image by driving N×M organic light emitting pixels using a voltage programming method or a current programming method. An organic light emitting pixel has a multilayer structure including an anode layer, an organic thin film layer, and a cathode layer. The organic thin film also has a multilayer structure including an emission layer (EML), an electron transport layer (ETL), and a hole transport layer (HTL) in order to enhance luminous efficiency by increasing the balance of electrons and holes. The organic thin film also includes a separate electron injection layer (EIL) and a separate hole injection layer (MIL). [0003] The OL...
