The large-sized screen 101 is formed by longitudinally and transversely lining up a plurality of the set pixels 106.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a display device in which a display screen is constituted by a plurality of light emitting units.

[0002]

2. Description of the Related Art As a conventional display device, there is a large image display device using a plurality of light emitting units.

In a conventional display device, R
(Red), G (Green) and B (Blue)
Such light-emitting elements are arranged on a display screen corresponding to a place where the light-emitting elements are installed, and the brightness of the emission color of each light-emitting element is adjusted to display video data.

[0004]

However, in the conventional display device, the RG is adjusted according to the size of the display screen.
Since the B light emitting elements are arranged and the arranged RGB are grouped into pixels according to the number of dots of the pixels, different designs are required according to the size of the pixels.

Further, it has not been possible to switch the display screen between a wide angle and a narrow angle for display.

The present invention provides an excellent display device that can use the same light-emitting unit regardless of the size of a pixel and can display a display screen by switching between a wide angle and a narrow angle.

[0007]

According to the present invention, a display device comprises:
One pixel of the display screen was composed of a plurality of light-emitting units each having a GB light-emitting element.

Therefore, a plurality of the same light emitting units can be used to form one pixel, and the size of one pixel can be changed by the number of light emitting units.

Further, the display device of the present invention is provided with a display control means for simultaneously controlling the display of a plurality of light emitting units constituting the pixel.

Therefore, it is possible to simultaneously control a plurality of pixels constituting one pixel for performing the same display control.

Further, in the display device according to the present invention, the display control means controls the light emission of the plurality of light emitting units constituting the pixel by the same sweep signal.

Therefore, a plurality of pixels constituting one pixel can be controlled simultaneously using the same scanning signal.

Further, the display device of the present invention is provided with switching means for switching between displaying one pixel with a plurality of light emitting units and displaying one pixel with one light emitting unit.

Therefore, the number of pixels on the display screen can be changed without changing the display screen.

In the display device according to the present invention, the display screen is constituted by a plurality of area screens, and a movable portion for changing a relative angle between the two area screens is provided at a connection position of the at least two area screens. And

Therefore, the display screen can be switched between a wide angle and a narrow angle for display.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view of a display device according to the first embodiment of the present invention.

In FIG. 1, the large screen 101 of the large-sized image display device has a large light emitting area of several m to several tens m square.

The light emitting unit 102 has a red LED
103, a green LED 104, and a blue LED 105. An aggregate pixel 106 is formed using four light emitting units 102, and a large screen 101 is formed by arranging a plurality of the aggregate pixels 106 vertically and horizontally.

Then, the vertical video information of the input video data is sent as a transmission signal by the display data transmitting device 110 to each of the vertical columns of the plurality of collective pixels 106 arranged on the large screen 101.

Therefore, since the same transmission signal is input to the four light emitting units of one collective pixel 106,
The luminance of each of the RGB of the aggregate pixel 106 can be controlled according to the input image.

Next, a second embodiment of the present invention will be described.

FIG. 2 is a front view of a display device according to a second embodiment of the present invention, and shows a small screen 201 of a video display device.
Is smaller than the large screen 101 of FIG.

One pixel of the small screen 201 is constituted by one light emitting unit 102 constituting the collective pixel 106, and a plurality of one light emitting unit 102 as one pixel is arranged on the small screen 201 vertically and horizontally. I have.

In the same manner as in the first embodiment, the vertical video information of the input video data is used as a transfer signal by the display data transmitting device 202, and the vertical light information of the plurality of light emitting units 102 arranged on the small screen 201 is displayed. Entered for each column.

Therefore, on the large screen 101, one pixel is composed of four light-emitting units 102 and an image is displayed. On the small screen 201, one pixel is composed of the same light-emitting unit 102. Images can be displayed.

Next, a third embodiment of the present invention will be described.

FIG. 3 is a top view of a display device according to a third embodiment of the present invention. The display screen is constituted by a plurality of light emitting units 102 with one or a plurality of light emitting units 102 as one pixel. It comprises a display screen 301 and a display screen 302.

A hinge 303 for rotatably connecting the display screen 301 and the display screen is provided.

The display screen 301 and the display screen 302
The display of the video data is performed by a display data transmitting device (not shown) as in the first embodiment.

Therefore, the display screen 301 and the display screen 30
When the display screen side is opened outward with the hinge 303 by the hinge 303, the width in which the image can be viewed can be widened. When the display screen side is closed inward, the width at which the image can be viewed can be reduced to a narrow angle.

[0033]

As described above, the image display device of the present invention can form a display screen using the same light emitting unit regardless of the size of the pixel. Further, the display screen can be switched to a wide angle or a narrow angle for display.
