Abstract

PURPOSE:To make it possible to perform a visible stereoscopic vision, by forming display sections, with two green picture elements and a red and blue picture elements arranged at diagonal positions respectively, thereby making the polarizing surfaces of respective green colors differ from each other through polarizing filter. CONSTITUTION:Display sections 11, each of which has two green picture elements 12, 13 and a red and blue picture elements 14, 15 arranged at diagonal positions respectively, are arranged in matrix-shape, thus a display element 1 of a flat matrix CRT is formed. Further, a polarizing filter 2 is provided on the front surface of the display element 1 for polarizing the light from the green picture elements 12, 13 by the right and left sides filters 21, 22 so as to make respective polarizing surfaces differ from each other by an angle of pi/2. Then, a picture image is observed by a stereoscopic vision glasses 3. Therefore, it is possible to prevent the lowering of an average brightness without polarizing the light of a red and blue colors, while ensuring the same space frequency band width of respective kinds of emission so as to perform visible stereoscopic vision.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a display element forming a display screen of a large-sized display device, and more particularly to a color display element capable of providing stereoscopic viewing.

[Conventional technology]

In this type of conventional flat CRT, as shown in Fig. 3, red, green, and blue pixels 0→, (auxiliary, μs) are arranged side by side to form a set. One display section α
(1), and a large number of display sections aη are provided in a matrix to form a large screen as a light emitting element.

Based on the above configuration, the conventional CFIT displays display sections (11) arranged in a matrix in arbitrary color tones to display various characters, figures, and other display contents on a large screen.

In addition, each red, green, and blue pixel (14) is added to enable stereoscopic viewing of the display screen on a conventional (furano) CRT.
, (12), ■) A configuration was adopted in which the emitted colored light was polarized. In other words, one of the pixels in the display section (1), which consists of a set of pixels 0→1 in the above-mentioned field, green, and blue, is covered with a polarizing filter, etc., and the light emitted from the covered pixel is This is a configuration in which the polarization planes of the two are different.

[Problem that the invention seeks to solve]

Since the structure is similar to that of the conventional flat I-CR1d, for a viewer looking at the display screen, the images shown to the left and right eyes are different, or the brightness of the images is different, making it impossible to see clearly in stereo. Especially conventional flat CRT
't''i had a problem in that when color display was performed, clear stereoscopic viewing could not be achieved.

This invention was made to solve the above-mentioned problems, and provides a display element that can make the spatial frequency bands of red, green, and blue tones the same and allows clear stereoscopic vision. The purpose is to

[Means for solving problems]

The display element according to the present invention has two green pixels and one red pixel and one blue pixel each forming a display section that displays a target color by controlling the light emission of each red, green, and blue pixel, and This is a configuration in which each green light emitted by each green pixel is emitted with different planes of polarization.

[Effect]

The display element according to the present invention does not polarize the colored light emitted from the red and blue pixels, which have weak luminance, so the average luminance does not decrease, and the spatial frequency bands of the red, green, and blue colored lights are the same. This allows for clear stereoscopic vision.

That is, the green light polarized by the right polarizing filter (21) passes only through the right polarizing glass (31) of the stereoscopic glasses (3) and reaches the viewer's right eye, and is blocked by the left polarizing glass 52). The green pixel (12) does not reach the observer's left eye.

Therefore, the viewer's right and left eyes can perceive images of exactly the same color tone, resulting in clear stereoscopic vision.

Although the above embodiment uses a polarizing filter, any means capable of polarizing each green light emitted by the two green pixels will produce the same effect. As a means for polarizing light, a polarizing prism (for example, Nicol), an artificial polarizing plate (for example, Polaroid), a Nerenberg polarizer using glass, or other liquid crystals can be used.

〔Effect of the invention〕

As described above, the display element according to the present invention uses two green pixels and one red pixel and one blue pixel to form a display section for displaying a target color by controlling the light emission of each red, green, and blue pixel. The green light emitted by the two green pixels is configured to emit light with different planes of polarization, so the colored light emitted by the red and blue pixels, which have weak luminance, is polarized. This prevents the average luminance from decreasing without causing a drop, and the spatial frequency bands of red, green, and blue light emission can be made the same, resulting in the effect that clear stereoscopic vision can be achieved.
