BACKGROUND

Field of Invention

The present disclosure relates to a display device. More particularly, the present disclosure relates to a display device that can improve the light transmittance of a light-emitting element.

Description of Related Art

With the rapid development of smart technology, automobile users' demand for in-car displays is not limited to excellent optical performance. Traditional large screens, combined screens, and curved screens are no longer favored by the new generation of young people.

Automobile interior cockpits will develop in the direction of intelligence in the future, especially the overall aesthetics, technology and touch of the interior. Surface design will transform from decorative to multifunctional, combining decoration and function, and future smart surface displays integrated with interior exterior design will gradually become a highlight of vehicle interiors, attracting consumers' attention. In order to create the overall atmosphere of the car room space, most of the surfaces of the display devices have the decorative film that can present decorative patterns, such as wood grain, checkerboard decorative films, etc.

A large number of multi-functional smart surface decorative films have appeared on the market currently, such as lighting control decorative films, which are relatively mature. However, products used in automotive displays face many problems with optical effects.

The decorative film of the vehicle display screen forms a pattern by applying semi-transparent ink on the entire glass cover currently. When the display screen is off, by controlling the transmittance of the ink, the display screen is invisible and integrated with other interior parts of the car. When the screen is lit, the light will be absorbed when passing through the semi-transparent ink on the glass cover, resulting in color distortion of the display screen and overlapping of the displayed image with the ink pattern, thereby resulting in a decrease in image quality and directly affecting the display effect of the display screen.

DETAILED DESCRIPTION

Hereinafter, various embodiments will be described, and one of ordinary skill in the art of the present disclosure shall readily understand the spirit and principles of the present disclosure by referring to the description in conjunction with the figures. However, although the description specifically describes some specific embodiments, the embodiments are merely exemplary, and shall not be considered to be limitative or exhaustive in all aspects. Therefore, for one of ordinary skill in the art, various variants and modifications of the present disclosure made without departing from the spirit and principle of the present disclosure would be apparent and can be achieved easily.

In the accompanying drawings, for clarity, the thickness of layers, membranes, panels, areas, or the like is exaggerated. In the whole specification, the same referential numeral indicates the same element. It should be understood that when an element such as a layer, a membrane, an area, or a substrate is referred as “on” another element or “connected to” another element, the element may be directly on another element or directly connected to another element, or there may be an intermediate element. On the contrary, when an element is referred as “directly on another element” or “directly connected to” another element, there is not an intermediate element. As used herein, the “connection” may refer to physical and/or electric connection (coupling). Therefore, for “electric connection” or “coupling”, there may be another element between the two elements.

Further, relative terms such as “lower” or “bottom” and “upper” or “top” may be used herein for ease of description to describe one element's relationship to another element as shown in the figures. It will be understood that relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, an element described as being “above” or “upper” relative to another element will then be “below” or “lower” relative to the other element. Thus, the term “above” encompasses both the above and below orientations depending on the spatial orientation of the device. Similarly, if the device in the figures is turned over, an element described as being “below” or “lower” relative to another element will then be “above” or “upper” relative to the other element. Thus, the term “below” encompasses both the below and above orientations depending on the spatial orientation of the device.

FIG. 1 is a top view of a display device 10 according to one embodiment of the present disclosure. FIG. 2 is a cross-sectional view along line 2-2′ in FIG. 1. Please refer FIG. 1 and FIG. 2, the display device 10 and 10a includes a display module 100 and a decorative layer 200. To be specific, the display module 100 includes a plurality of sub-pixels 110, and a line connecting the midpoints of any two opposite sides of each sub-pixel 110 forms an auxiliary center line 118. More specifically, the display module 100 at least includes a display substrate 120, a plurality of sub-pixels 110 on the display substrate 120, and an encapsulation layer 130 covering the plurality of sub-pixels 110. It can be understood that the display module 100 may have active light emitting display technology. For example, the display module 100 described in the present disclosure may have active light-emitting display technology applied to organic light emitting diodes (OLED), mini LED, or micro LED. The display technology of the display module 100 described in the present disclosure may also be reflective liquid crystal display technology or electronic paper (e-Paper) display technology. For example, the display technology of the display module 100 described in this disclosure may be a reflective liquid crystal display technology using super-twisted nematic display (STN display), or an electronic paper display technology using electrophoretic display (EPD). The present disclosure is not limited to the above application fields. A person having ordinary skill in the art can apply display technology with similar display effects to the display module proposed in the present disclosure without departing from the teachings of the disclosure. In this embodiment, the display module 100 takes a micro light-emitting diode display as an example.

These sub-pixels 110 can emit light of different color, such as red light, green light, and blue light. For example, these sub-pixels 110 include a first sub-pixel 112, a second sub-pixel 114, and a third sub-pixel 116, which can emit red light, green light, and blue light respectively. These sub-pixels 110 are arranged on the display substrate 120 in the order of emitting colors of blue, green, and red, for example, but are not limited thereto. In addition, in this embodiment, a single pixel includes two first sub-pixels 112, two second sub-pixels 114, and two third sub-pixels 116, in which one of the two sub-pixels with the same emitting color is an effective sub-pixel and the other one is a backup sub-pixel. That is to say, in the lighting test, the effective sub-pixels can be detected and judged whether their light emission has failed. If it fails, the spare sub-pixel is turned on for replacement.

In some embodiments, the plurality of sub-pixels 110 are, for example, micro light-emitting diodes, and their size is, for example, on the order of microns, for example, in the range of less than 100 microns and greater than 0 microns, but the present disclosure is not limited thereto. These micro light-emitting diodes can be first formed on a growth substrate (not shown), and then transfer to the display substrate 120 using mass transfer technology. In other embodiments, the plurality of sub-pixels 110 are, for example, sub-millimeter light-emitting diodes (Mini LEDs) or organic light-emitting diodes (OLEDs), but the present disclosure is not limited thereto.

In some embodiments, the encapsulation layer 130 may be anisotropic conductive film (ACF), ultraviolet glue, or silver glue, but not limited thereto.

Please continue to refer to FIG. 1 and FIG. 2, the decorative layer 200 is disposed over the display module 100. The decorative layer 200 has at least one through hole 220. To be specific, the at least one through hole 220 penetrates the decorative layer 200. In some embodiments, the at least one through hole 220 may be formed in the decorative layer 200 using laser drilling technology. In some embodiments, the shape of the at least one through hole 220 is similar to the shape of the sub-pixel 110. In other embodiments, the shape of the at least one through hole 220 may be different from the shape of the sub-pixel 110. More specifically, each sub-pixel 110 corresponds to n through holes, and n is a positive integer. It is worth noting that the corresponding through hole can be formed only over the effective sub-pixel after performing the lighting test as mentioned above. In this way, there is no need to spend extra cost to form a through hole over the spare sub-pixel. The corresponding relationship between each sub-pixel 110 and the through hole is described in detail below.

FIGS. 3A, 3B, 3C, 3D, and 3E are top views of the corresponding relationships between sub-pixels and through holes in various embodiments of the present disclosure. As shown in FIG. 3A, when n is 1 (that is, the number of through holes 220 is 1), in a top view, the sub-pixels 112/114/116 are located within the coverage of the through holes 220.

In some embodiments, when the second top view area exceeds 6 times the first top view area, excessive size of the through hole 220 will cause the resolution of the decorative pattern to decrease. On the contrary, when the second top view area is less than 1.5 times the first top view area, the overall brightness of the display device cannot be effectively improved.

As shown in FIGS. 3B, 3C, 3D, and 3E, when n is greater than or equal to 2 (that is, the number of through holes 220 is greater than or equal to 2), these n through holes 220 are arranged at equal intervals along the auxiliary center line 118.

In an embodiment where the number of through holes 220 is one, the through hole 220 is located within the coverage of the sub-pixels 312/314/316.

FIG. 10 is a top view of a display device according to yet another embodiment of the present disclosure. FIG. 11 is a cross-sectional view along line 9-9′ in FIG. 10. Please refer to FIG. 10 and FIG. 11, the difference between the display device 40 and the display device 30 is that each sub-pixel 312/314/316 included in the display module 320 in the display device 40 corresponds to a plurality of through holes 220. That is, a single sub-pixel corresponds to two or more through holes 220. In other words, when n is greater than or equal to 2 (that is, the number of through holes is 2 or greater than 2), the n through holes are arranged at equal intervals along the auxiliary center line 319.

In some embodiments, when n is greater than or equal to 2, the n through holes 220 are arranged at intervals within the coverage of the sub-pixels 312/314/316. In some embodiments, when n is greater than or equal to 2, the n through holes 220 are arranged at equal intervals along the long sides of the sub-pixels 312/314/316. In some embodiments, when n is greater than or equal to 2, the n through holes 220 are arranged at equal intervals along the short sides of the sub-pixels 312/314/316.
