Embodiment Construction

[0042] figure 1 Schematically shows an equivalent circuit diagram of a part of an electroluminescent color display screen 1 comprising a plurality of light emitting segments arranged in n rows 2 and m columns 3 . Each intersection of the row electrode 2 and the column electrode 3 forms a light emitting segment. The display screen also includes a row selection circuit 21 (for example, a multiplexing circuit) and a data register 22 . Information given from the outside, such as a video signal, is loaded into each part of the data register 22 after being processed by the control unit 23 according to the information to be displayed. Mutual synchronization between the row selection and the application of voltages to the column electrodes is carried out by the control unit 23 via the control line 24 .

[0043] figure 2 It is a schematic diagram of a part of the electroluminescence display screen 1 in the prior art. For the sake of clarity, this figure and some subsequent figures...

Abstract

The positional arrangement of the color section in each pixel of an electroluminescent display panel is different from the positional arrangement of the color sections in at least one adjacent pixel. This yields an improved image quality as perceived by the viewer, in particular when moving images are displayed on low-resolution displays. A preferred embodiment of the invention is an electroluminescent display panel in which the color sections are arranged on continuous lines, which are oriented to run diagonally across the display panel.

Description

technical field [0001] The present invention relates to an electroluminescent color display screen comprising a plurality of pixels arranged in rows and columns to form a grid pattern, each pixel comprising at least two sub-pixels, the first sub-pixel emits light of a first color, and the second sub-pixel emits light of a first color The second sub-pixel emits light of a second color different from the first color. [0002] The invention also relates to a method of manufacturing an electroluminescent color display and an electronic device comprising an electroluminescent color display. Background technique [0003] There are known electroluminescent display screens comprising a plurality of organic electroluminescent devices. An electroluminescent device is a device that utilizes the phenomenon of electroluminescence to emit light when properly connected to a power source. The so-called "electroluminescence" includes some common characteristics of discharge in gaseous, liq...
