Description

[Technical Field]

[0001] The present invention relates to optoelectronic devices, and more particularly to display devices. [Background technology]

[0002] An LED display device includes a circuit board and a plurality of LED elements electrically connected to the circuit board. Inheriting the characteristics of LEDs, LED displays have advantages such as low power consumption, high efficiency, high brightness, and fast response time. Compared to organic LED displays, LED displays also have the advantages of easy color adjustment, a long light-emitting lifetime, and no image burn-in. Therefore, LED displays are considered a next-generation display technology.

[0003] A light emitting diode display device can include multiple light emitting element substrates, which are joined together in a spherical shape to provide a spherical display screen. However, since a spherical display device typically includes multiple different light emitting element substrates, high development costs are required, and when viewed at a large viewing angle, the light emitting diode display device is prone to color shift problems due to a fixed arrangement order, which ultimately affects the display quality of the spherical light emitting diode display device.

The plurality of light-emitting element substrates includes a first light-emitting element substrate. The base of the first light-emitting element substrate is an N-sided shape, where N is a positive integer greater than 4. The N-sided shape has a first edge and a second edge. The first edge and the second edge are substantially parallel to two of the dummy longitude lines of the sphere, respectively.

DETAILED DESCRIPTION OF THE INVENTION

[0008] Reference will now be made in detail to exemplary embodiments of the invention, examples of which are illustrated in the drawings. Wherever possible, the same element designators are used in the drawings and the description to refer to the same or like parts.

[0009] When an element, such as a layer, film, region, or substrate, is referred to as being "on" or "connected" to another element, it should be understood that it may be directly on or connected to the other element, or that intermediate elements may be present. Conversely, when an element is referred to as being "directly on" or "directly connected to" another element, there are no intermediate elements present. As used herein, "connected" means physically and / or electrically connected. Also, "electrically connected" or "coupled" can mean that there are other elements between the two elements.

[0010] As used herein, "about," "approximate," or "substantially" includes the value and the mean within an acceptable deviation range of the specified value as determined by one of ordinary skill in the art, taking into account the measurement being discussed and the specific number of errors associated with the measurement (i.e., limitations of the measurement system). For example, "about" can refer to within one or more standard deviations of the value, or within ±30%, ±20%, ±10%, or ±5%. Also, as used herein, "about," "approximate," or "substantially" can refer to a relatively acceptable deviation range or standard deviation depending on the optical, etching, or other properties, rather than using one standard deviation to apply to all properties.

[0011] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Terms as defined in commonly used dictionaries are to be construed as having a meaning consistent with their meaning in the context of the relevant art and this invention, and will be further understood not to be construed as having an ideal or overly formal meaning unless so expressly defined herein.

[0028] 10 is a schematic diagram of a light-emitting element substrate 100-4 in one embodiment of the present invention. Referring to FIGS. 1, 2, 4, and 10, local portion r2 is located between local portion r1 and local portion r3, and light-emitting element substrate 100-4 is located at local portion r2.

[0029] FIG. 11 is a schematic diagram of a plurality of light-emitting element substrates 100-2 in one embodiment of the present invention. Referring to FIGS. 1, 2, 7, and 11, the plurality of light-emitting element substrates 100 of the display device 10 includes a plurality of light-emitting element substrates 100-2. The plurality of light-emitting element substrates 100-2 may be located on opposite sides of the dummy equator line 1d.

The plurality of pixel structures 120 of each light-emitting element substrate 100-2 includes a plurality of first pixel structures 120-1 and a plurality of second pixel structures 120-2.

[0030] This can alleviate the color shift problem at large viewing angles in the display device 10. While alleviating the color shift problem at large viewing angles, two light-emitting element substrates 100-2 installed in the southern and northern hemispheres of the sphere 1, respectively, and located at the same latitude, can share the same design, eliminating the need to design multiple light-emitting element substrates 100-2 located in the northern and southern hemispheres of the sphere 1, respectively. In addition, abnormalities are less likely to occur in the joining slits S2 of the two light-emitting element substrates 100-2 (for example, the appearance of a bright line and / or a dark line of a specific color that can be observed visually).

[0031] FIG. 12 shows the relative luminance of the first color light, the second color light, and the third color light at each viewing angle of the display device 10 according to an embodiment of the present invention.

The comparative example display device (not shown) corresponding to FIG. 13 is similar to the display device 10 according to the embodiment of the present invention corresponding to FIG. 12, with the following differences: In the comparative example display device, the first light-emitting element 122R, the second light-emitting element 122G, and the third light-emitting element 122B of the plurality of pixel structures 120 located on the same side of the dummy equator 1d of the sphere 1 are all arranged along the same first meridian direction B1 or second meridian direction B2. Comparing FIGS. 12 and 13 reveals that the display device 10 according to an embodiment of the present invention can indeed improve the color shift problem at large viewing angles. For example, the color shift of the comparative example display device at an upward viewing angle of -60° is Δu'v' = 0.016, and the color shift of the comparative example display device at a downward viewing angle of 60° is Δu'v' = 0.026, and the color shift of the example display device 10 at an upward viewing angle of -60° is Δu'v' = 0.009, and the color shift of the example display device 10 at a downward viewing angle of -60° is Δu'v' = 0.009.

Referring to FIG. 16, the plurality of light-emitting element substrates 100 of a display device 10C includes a plurality of light-emitting element substrates 100-2C bonded in the latitudinal direction A. The base 110 of each light-emitting element substrate 100-2C is non-rectangular. The multiple pixel structures 120 of each light-emitting element substrate 100-2C include multiple first pixel structures 120-1 and multiple second pixel structures 120-2, and the first light-emitting element 122R, second light-emitting element 122G and third light-emitting element 122B of each first pixel structure 120-1 are arranged sequentially in a first meridian direction B1, and the first light-emitting element 122R, second light-emitting element 122G and third light-emitting element 122B of each second pixel structure 120-2 are arranged sequentially in a second meridian direction B2, and the first meridian direction B1 and the second meridian direction B2 are substantially parallel to multiple dummy meridians 1b (see Figure 1), and the first meridian direction B1 and the second meridian direction B2 are opposite to each other. The plurality of first pixel structures 120-1 and the plurality of second pixel structures 120-2 of each first light-emitting element substrate 100-2C are arranged in a plurality of pixel columns R, and the plurality of first pixel structures 120-1 and the plurality of second pixel structures 120-2 of each pixel column R are arranged alternately in a latitude direction A that is substantially parallel to a plurality of dummy latitude lines 1a (see Figure 1), and the sum of the numbers of the plurality of first pixel structures 120-1 and the plurality of second pixel structures 120-2 of each pixel column R is an even number.

[0039] Therefore, when two adjacent light-emitting element substrates 100-2C are bonded to a portion of a sphere 1 (see FIG. 1), in the portion of the sphere 1, the plurality of first pixel structures 120-1 and the plurality of second pixel structures 120-2 of the two bonded pixel columns R of the two adjacent light-emitting element substrates 100-2C in the latitude direction A can be maintained in an alternating arrangement, without a situation occurring in which the two pixel structures 120 located closest to the bonding slit S3 and on both sides of the bonding slit S3 are both the first pixel structure 120-1 or the second pixel structure 120-2. This makes it possible to prevent the display device 10C from having a situation in which the bonding slit S3 is arranged in an order different from that of the plurality of pixel structures of the element substrates.
