DETAILED DESCRIPTION OF THE EMBODIMENTS

[0035] The invention is further illustrated by detailed description of the embodiments combined with the drawings.

[0036] As shown in FIG. 1, the present invention includes a SC electronic controller and a display screen SN. The SC electronic controller may be a scrambler, mixer or complex; the display screen SN has a plurality of display pixels. The SC electronic controller connects with the display screen SN. The SC electronic controller controls transmission and image processing. Send the image information data for the left & right eye to the display screen SN with the SC electronic controller. Then, separate the left eye image and the right eye image with a polarization system having a plurality of polarizing films (the display pixels of the display screen are covered with the L-type and R-type polarizing films or the polarization boards which have orthogonal relations between the polarizing angles or between the polarizing phase, wherein the L-type polarizing film or polarization board transmits light emitted by the pixel for emitting light for the left eye, and the R-type polarizing film or polarization board transmits light emitted by the pixel for emitting light for the right eye). The SC electronic controller sends the image information data for the left & right eyes to the pixels shielded with L-type and R-type polarizing film or polarizing plate, respectively, to form the left and the right eye images. When viewing, an observer can wear a pair of polarizing glasses including polarizing film or polarizing plate having orthogonal relations between the polarizing angles or between the polarizing phase to separate the left and the right eye images, such that the left eye image and the right eye image enter the left eye and the right eye, respectively, to form a stereoscopic image in the observer's brain.

[0037] The display pixel of the present invention refers to physical pixel, each display pixel includes two individual electronic pixels, i.e. inserting two individual electronic pixels within each display pixel. In this way, stereoscopic display is realized, when each physical pixel can be divided into two completely individual pixels, resolution of the left eye and the right eye image have no loss. The individual electronic pixel in the present invention refers to a 3-in-1 electronic pixel, that is there are three primary colors in one electronic pixel and each electronic pixel is capable of forming full color. Each of two individual electronic pixels include one left-eye pixel labeled by L for emitting light for the left eye image and one right-eye pixel labeled by R for emitting light for the right eye image. The left-eye and the right-eye pixels can be arranged horizontally, vertically, or diagonally. Specifically, the left-eye and the right-eye pixels can be arranged in a row, as shown in FIG. 2; or arranged in a column, as shown in FIG. 3; or arranged in a right-inclined line, as shown in FIG. 4; or arranged in a left inclined line, as shown in FIG. 5. The physical pixel 1 is pointed out in FIGS. 2-5. As shown in FIG. 6, FIG. 7, FIG. 8 and FIG. 9, the display pixels or the display elements of the display screen can be divided into two sets: the left-eye pixels L and the right-eye pixels R, and the left-eye pixels L and the right-eye pixels R can be arranged row by row, column by column, in a parity array or even parity array. It should be mentioned that, in every physical pixel, merely two individual electronic pixels are enclosed wherein, the objective of the invention would not be achieved if more or less individual electronic pixels are enclosed in one physical pixel. Moreover, in every individual electronic pixel, merely three primary colors are enclosed wherein, that is merely two sets of RGB colors are enclosed in each physical pixel, the objective of the invention would not be achieved if more or less sets of RGB colors pixels are enclosed in one physical pixel.

[0038] The light polarizing film may use linear polarization or circular polarization to polarize light. In linear polarization mode, the polarizing angle difference between the left eye and the right eye is 90°; errors are less than ±10%. In circular polarization mode, either the two polarizing angles are in parallel and the two phases are orthogonal, or the polarizing angles are orthogonal, and the phases are in parallel, errors are less than ±10%. For the physical pixels, the polarizing films may be separated, i.e. each polarizing film is set on a single physical pixel; the polarizing films may be set row by row or column by column, i.e., the polarizing films are shaped into strips or belts to set on a row or a column of the physical elements or physical pixels; or the polarizing films may be set into blocks or plates for covering or shielding some pixels. The direction of polarizing light of the display screen SN is consistent with the direction of polarizing light of the polarizing glasses PG.

[0039] when the present invention is applied in a practical SD (standard-definition), HD (high-definition), or UHD (ultra-high-definition) display system, since there are two individual electronic pixels including three primary colors (i.e., red, green and blue colors) in each physical pixel for respectively emitting light for the left and right eyes, there is no pixel loss to result in the resolution loss. For example, when applying the display screen comprising a plurality of physical pixels each having two individual pixels arranged in a column in a practical SD, HD, or UHD display system, the way of data transmission to the left and right eyes is demonstrated as in FIG. 10. Such a way of data transmission ensures that there is no pixel loss to result in the resolution loss.

[0040] The manufacturing process of the invention includes:

[0041] step 1, several display pixels are set on the display screen SN; the display screen SN is connected to the SC electronic controller; and the display pixels are controlled by the SC electronic controller to emit light;

[0042] step 2, two individual pixels are set at each display pixel, in which one of the two individual pixels emits light for the left eye image, and the other emits light for the right eye image; each of the two individual pixels comprises three primary RGB colors.

[0043] step 3, the polarizing film is set on each display pixel. The polarizing film can be sticked or covered on each display pixel, fixed on each display pixel by other way. The screen surface can be waterproof processed for outdoor application.

[0044] While particular embodiments of the invention have been shown and described, it will be obvious to those skilled in the art that changes and modifications may be made without departing from the invention in its broader aspects, and therefore, the aim in the appended claims is to cover all such changes and modifications as fall within the true spirit and scope of the invention.
