Problems solved by technology

[0004] When the ideal image data (hereinafter referred to as "original image"), which is the source of the display image, is displayed on the above-mentioned display device, the position of the boundary area between the light pattern and the dark pattern of the original image (hereinafter referred to as "contour") cannot be Displayed at a location that is thinner than the size of this pixel, thus degrading the quality of the displayed image by bringing about a phenomenon called aliasing, in which outlines are displayed in a jagged shape

Embodiment 1

[0059] refer to figure 1 The structure of the liquid crystal display device in Example 1 of the present invention will be described.

[0060] In the case of a liquid crystal display device, a prescribed voltage is applied to each pixel 1 to drive the liquid crystal, whereby the transmittance of each pixel 1 is controlled. Light emitted from the backlight transmits through each pixel 1 and is emitted from the display surface, so the transmittance of each pixel 1 is controlled, so that the brightness of each pixel can be controlled to display an image.

[0061] A switching element 11 is provided on each pixel 1 to apply a prescribed voltage to each pixel 1 , and a signal voltage of a data wiring is applied through the switching element 11 . Also, the switching element 11 is provided with a gate electrode connected to the gate wiring 12 so as to control the switching element, and ON / OFF of the switching element can be controlled by switching the gate voltage.

Embodiment 2

[0079] In Example 2 as another embodiment of the present invention, as Figure 7 As shown, like Embodiment 1, the shape of the pixel 2 is cross-shaped, and the pixels are rotated and arranged obliquely so that the array of the centers of gravity of the pixels is changed. As indicated by reference numeral 3a, the pixel array is a square array. In other words, the pixels constitute an array in which the pixels are arranged point-symmetrically in the horizontal row direction and the vertical row direction. Also, the boundaries of these pixels are not straight lines in any direction.

[0080] That is, the centers of gravity of the pixels 2 are arranged in a square array in which horizontal rows and vertical rows of pixels are linearly arranged, thereby providing an advantage that the conversion process from the original image to the displayed image can be compared with the triangular array. Relatively easy to do.

Embodiment 3

[0082] In embodiment 3 of the present invention, as Figure 8 As shown, there is provided an array in which, while setting the pixel shape to the same pixel shape as in Embodiment 1, substitution occurs in the horizontal row and vertical direction in the pixel array. As indicated by reference numeral 3b, the pixel array has a difference of 90 degrees compared with the ordinary triangular array. In other words, the pixels constitute an array in which the pixels are arranged line-symmetrically in the vertical row direction and point-symmetrically in the obliquely upward and obliquely downward directions. Also, the boundaries of these pixels are not straight lines in any direction.

[0083] That is to say, in Embodiment 1, the centers of gravity of the pixels 1 are arranged linearly in the horizontal direction, and in the direction of the vertical rows, the centers of gravity of the pixels are arranged in a zigzag manner, wherein the positions of the centers of gravity of each p...

Abstract

The present invention relates to a display device, and specifically provides a display device capable of reducing the sense of discontinuity in display. A display device according to the present invention is provided with a plurality of pixels having an opening and each pixel is controlled in brightness to display an image, and the display device includes a pixel structure and a pixel array as follows: the concave portion faces the opening of the pixel Different four directions on the same plane of and other directions as lateral directions are formed, and opening portions of adjacent pixels are arranged in the above-mentioned concave portion.

Description

technical field [0001] The present invention relates to a structure of a display device applied to an overall flat panel display, in particular to the opening shape of a display pixel (hereinafter referred to as "pixel") in the display device. The "pixel" mentioned above refers to the opening area (hereinafter referred to as "opening"). Unless otherwise specified, the brightness of the pixel can actually be controlled, and the light-shielding area between the pixels is not included. Background technique [0002] As a mainstream display device for displaying pictures and images, flat panel displays have various display methods, such as LCD (Liquid Crystal Display), PDP (Plasma Display) and OLED (Organic Electroluminescence Flat Panel Display), which adopt many Small pixels and the display method of controlling the brightness of each pixel to display an image, so the present invention can be applied to these display methods. [0003] To cite LCD as a representative flat panel...
