Problems solved by technology

[0008] Regular structures cause artifacts, especially when viewing the screen at close range: black gaps between rows become visible, colored stripes appear, etc.
In addition, when such screens are used together with corner-selective arrays such as cylindrical lens arrays to produce autostereoscopic displays, other artifacts such as moiré patterns are prone to Appear

Embodiment Construction

[0034] figure 2 It is shown that by deforming each sub-pixel to give each sub-pixel a parallelogram shape, from figure 1 The structure of the screen derived from the RVB type three-color screen. The top short side and the bottom short side of each sub-pixel move to the left and right respectively, and the long side is inclined at an angle α of 18°43 (18° and 43% in decimal notation) relative to the vertical. exist figure 2 In the specific example of , the relative movement of the short side is substantially equal to the width of one sub-pixel. Therefore, the top short sides of the (blue) sub-pixels in the L row and C column are aligned with the bottom short sides of the (green) sub-pixels in the L-1 row and C-1 column. Likewise, the bottom short sides of the sub-pixels in the L row and C column are aligned with the top short sides of the (red) sub-pixels in the L+1 row and C+1 column. Symmetrical configurations are likewise possible.

[0035] In this way, the black line...

Abstract

A display screen (E), advantageously of the flat type, comprising a matrix of pixels (P) arranged in rows and columns perpendicular to said rows, each pixel comprising three or more sub-pixels (SP) of different colors (RGB), in alignment in the direction of said rows and presenting a shape that is elongate, the screen being characterized in that each said sub-pixel presents a main dimension forming a non-zero angle α relative to the direction of said columns. The screen may advantageously be fitted with an angle selection array for autostereoscopic display having main axes forming an angle α relative to the direction of said columns and at a pitch that enables M≧2 sub-pixels to be covered.

Description

technical field [0001] The present invention relates to a display screen, in particular to a flat-panel TV, computer or similar screen. The display screen can obtain better appearance image quality than conventional screens at a given resolution. The screen of the invention is especially suitable for automatic stereoscopic display, especially using the technique described in document EP1779181 in the applicant's name. However, it is advantageous to use the invention even in non-autostereoscopic applications. [0002] The present invention can be applied to various types of screens as long as these screens have a matrix of pixels each composed of sub-pixels of various colors. By way of example, liquid crystal display (LCD) screens, plasma screens, organic light emitting diode (OLED) screens, etc. may be mentioned. Background technique [0003] Conventional display screens, and especially flat screens, consist of rectangular light emitting surfaces divided into vertical colu...
