Description

Splicing display device

This novel creation relates to a display device, and particularly to a spliced display device.

In a large-sized display device, multiple displays can be integrated by splicing to provide a large-sized display screen. However, the frame of the display and the assembly structure between adjacent displays cause discontinuous display images between the display and the display, which further affects the display effect. In order to eliminate the discontinuity of the display image, it is proposed that an external optical element can be used, which utilizes the principle of refraction to shield the splice. However, the external device will cause the overall appearance to be abrupt, and it is easy to produce large errors in optical control. In addition, it is easy to observe the presence of splices at large viewing angles.

The novel creation provides a splicing display device with good display effect.

In this embodiment, the display 100 includes an upper substrate 110, a lower substrate 120, a color filter layer 130, a display medium layer 140, a plastic frame 150, and a housing 160. The color filter layer 130 is disposed on the upper substrate 110. The plastic frame 150 joins the upper substrate 110 and the lower substrate 120. The display medium layer 140 is located in the enclosed space formed by the plastic frame 150, the upper substrate 110 and the lower substrate 120. The housing 160 forms an accommodating space for accommodating the upper substrate 110, the lower substrate 120, the color filter layer 130, the display medium layer 140, and the plastic frame 150 therein.

In addition, the display 200 may further include a backlight module BL2 to provide light L required for displaying the picture.

In this embodiment, the liquid crystal display (LCD) is used as an example for the display 100 and the display 200, but the creation of the present invention is not limited to this. In other embodiments, the display 100 and the display 200 may also be light emitting diode (LED) displays, organic light emitting diode (OLED) displays, or other suitable displays or display units.

In this embodiment, the connection layer 400 is in physical contact with the upper substrate 110 of the display 100 and the upper substrate 210 of the display 200. The refractive index of the optical cover 300 is greater than the refractive index of the connection layer 400, and the refractive index of the connection layer 400 is less than the refractive indexes of the upper substrate 110 and the upper substrate 210. For example, when the viewing angle θ is 119 degrees, the refractive index of the optical cover 300 is, for example, close to 1.4, the refractive index of the connection layer 400 is, for example, close to 1, and the refractive indexes of the upper substrate 110 and the upper substrate 210 are, for example, close to 1.4 . At this time, the viewer in front of the display device 10 will not notice the discontinuous picture in the surrounding splicing area B1 within the range of the viewing angle θ. However, the creation of the present invention is not limited to this. In other embodiments, the refractive index relationships between the upper substrate 110 and the upper substrate 210, the optical cover 300, and the connection layer 400 may have other designs according to viewing angle requirements. For example, when the viewing angle θ is 89 degrees, the refractive index of the optical cover 300 is, for example, close to 1.4, the refractive index of the connection layer 400 is, for example, close to 1.4, and the refractive indexes of the upper substrate 110 and the upper substrate 210 are, for example, close to 1.4 .

In this embodiment, the material of the optical cover 300 is, for example, transparent materials such as glass, polycarbonate (Polycarbonate, PC), and polymethyl methacrylate (PMMA). The connection layer 400 is, for example, a transparent connection material such as optical clear adhesive (OCA). The connection layer 400 can provide better stability between the optical cover 300 and the displays 100 and 200, so that the spliced display device 10 can have better optical stability.

FIG. 3 is a partially enlarged schematic view of a splicing display device near another splicing place according to another embodiment of the new creation. FIG. 4 is a partially enlarged schematic view of a splicing display device in the vicinity of a splicing location of another embodiment of the new creation. Please refer to FIGS. 3 and 4. The spliced display device 20 shown in FIG. 3 is similar to the spliced display device 30 shown in FIG. 4 and the spliced display device 10 shown in FIG. 2, wherein the same reference numerals are used to indicate the same or similar Components, and the description of the same technical content is omitted. For the description of the omitted parts, reference may be made to the description and effects of the foregoing embodiments, and the following embodiments will not be repeated. The main difference between the spliced display device 20 shown in FIG. 3 and the spliced display device 30 shown in FIG. 4 and the spliced display device 10 shown in FIG. 2 is the cross-sectional shape of the optical projection of the optical cover. As shown in FIG. 2, the cross-sectional shape of the optical protrusion 320 of the optical cover 300 of the spliced display device 10 is a polygon (FIG. 2 is a trapezoid as an example). As shown in FIG. 3, the cross-sectional shape of the optical protrusion 520 of the optical cover 500 of the spliced display device 20 is triangular. As shown in FIG. 4, the cross-sectional shape of the optical protrusion 620 of the optical cover 600 of the spliced display device 30 is arc-shaped, but the creation of the present invention is not limited to this.

It is worth mentioning that when the refractive indexes of the upper substrate 110, the upper substrate 210, the connection layer 400, and the optical covers (such as the optical cover 300, the optical cover 500, and the optical cover 600) remain unchanged, when When the cross-sectional shape of the optical projection of the optical cover is a polygon or an arc with many sides (at a microscopic angle, the arc can be regarded as being composed of an infinite number of continuously bent sides), the light L The deflection effect of various angles can be generated by the optical protrusion, which can make the shielding effect of the surrounding splicing area better.

In addition, the optical protrusion may be in physical contact with the display 100 and the display 200, or may be kept at a distance from the display 100 and the display 200. For example, the optical protrusion 320 shown in FIG. 2 is in physical contact with the display 100 and the display 200, however, the optical protrusion 320 may also be kept at a distance from the display 100 and the display 200. The optical protrusion 520 shown in FIG. 3 is in physical contact with the display 100 and the display 200, for example, however, the optical protrusion 520 may be kept at a distance from the display 100 and the display 200. The optical protrusion 620 shown in FIG. 4 is, for example, maintained at a distance d from the display 100 and the display 200, however, the optical protrusion 620 may also be in physical contact with the display 100 and the display 200.

In summary, in the spliced display device of the present invention, by the configuration of the optical projection, the light transmitted from the edge of the display area can be deflected toward the surrounding splicing area through the optical projection, so that it can achieve shielding The effect of the surrounding splicing area, thereby eliminating the discontinuity of the display screen. In addition, the optical protrusion protrudes from the first surface of the plate toward the display, and the plate and the optical protrusion are integrally formed and made of the same material. Therefore, the viewer is less likely to perceive the presence of the splice and can be more precise in optical control. In this way, the spliced display device created by the present invention can have a good display effect.
