Problems solved by technology

Correspondingly, the area allocated to each pixel structure is quite small. If the above-mentioned single pixel structure has multiple pixel areas, the area of ​​each pixel area will be further reduced. At this time, more The setting of two active components will occupy too much space and cause the aperture ratio to decrease, and it is easy to have the problem of excessive parasitic capacitance.

Abstract

A pixel structure includes a scanning line, a data line, a first pixel unit and a second pixel unit. The first pixel unit includes a first active element and a first pixel electrode electrically connected with the first active element. The first active element includes a first gate, a first source and a first drain. The first source is electrically connected with the data line. The first drain is electrically connected with the first pixel. The second pixel unit includes a second active element and a second pixel electrode electrically connected with the second active element. The second active element includes a second gate, a second source and a second drain. The first gate and the second gate are electrically connected with the scanning line. The second drain is electrically connected with the second pixel electrode. The first drain is electrically connected with the second source.

Description

technical field [0001] The present invention relates to a pixel structure, and in particular to a pixel structure in which active elements are connected in series. Background technique [0002] The current common pixel structure of the display panel is formed by arranging an active device in a pixel region together with a single pixel electrode. However, in this way, the display medium (such as liquid crystal compound) driven by a single pixel structure has only a single degree of deflection, so the user can only watch a good-quality display image within a certain viewing angle range. In order to realize a display function with a wide viewing angle, a common pixel design method is to divide a pixel structure into at least two pixel regions, wherein each pixel region is configured with an active element and a pixel electrode, for example. And the pixel electrodes in different pixel regions can have different alignment structures and / or have different potentials, so the displ...
