Description of Related Art

With the rapid advancement of technology, display device technology is undergoing a revolutionary change, from liquid crystal displays to today's micro-light-emitting diode (micro-LED) display devices. Micro-LED display devices offer higher resolution but require lower energy consumption. Therefore, micro-LED display devices may be widely used in various fields, including mobile phones, watches, and other consumer electronic products.

However, with the continuous advancement of display technology, the market's requirements for display quality and appearance design are also growing. An important trend is to achieve superior display quality, including higher color accuracy, better contrast, and more engaging visual effects. At the same time, consumers have also raised higher expectations for the appearance design of displays. Consumers expect narrower bezels, so that they can enjoy more stunning visual effects due to a larger screen ratio. Therefore, in order to satisfy market needs, many manufacturers are committed to developing display devices with better display quality and narrower bezels.

SUMMARY

The disclosure provides a display device featuring advantages including good display quality and a narrow bezel.

At least one embodiment of the disclosure provides a display device having a driver substrate and a first light-emitting unit. The driver substrate has a display region and a peripheral region. The first light-emitting unit is disposed on the driver substrate and includes a first microcontroller, a plurality of first pixels, and a plurality of first supplementary pixels. The first microcontroller is disposed on the display region and is electrically connected to the driver substrate through a plurality of first connection pads. The plurality of first pixels and the plurality of first supplementary pixels are electrically connected to the first microcontroller and are disposed on the display region. The first pixels are arranged in two rows extending in a second direction in a first direction. The first supplementary pixels are arranged in two other rows extending in the second direction in the first direction. The first microcontroller is disposed between the first pixels in the two rows in the first direction, and the first supplementary pixels in the two other rows are at least partially aligned with the first pixels in the two rows in the first direction.

To sum up, by using the first microcontroller to control the first pixels and the first supplementary pixels, the circuit layout of the display device is simplified, and the adverse effects of the circuit on the display quality is further reduced. Further, the first supplementary pixels are at least partially aligned with the first pixels in the first direction, so that the problem of jagged edges of the display region caused by uneven pixel arrangement is prevented.

To make the aforementioned more comprehensible, several embodiments accompanied with drawings are described in detail as follows.

DESCRIPTION OF THE EMBODIMENTS

FIG. 1 is a schematic top view of a display device 1a according to a first embodiment of the disclosure. It should be noted that in FIG. 1, various traces in the light-emitting unit are omitted and the pixels in the light-emitting unit are simplified into rectangles.

The driver substrate DS includes a substrate and electronic components (e.g., transistors, capacitors, resistors, etc., which are not shown separately in the figure) located on the substrate. The substrate is, for example, a rigid substrate, and a material of the substrate may be glass, quartz, an organic polymer, an opaque/reflective material (e.g., a conductive material, metal, a wafer, ceramics, or other suitable materials), or other suitable materials. However, the disclosure is not limited thereto, and in other embodiments, the substrate may also be a flexible substrate or a stretchable substrate. For instance, materials of the flexible substrate and the stretchable substrate include, for example, polyimide (PI), polydimethylsiloxane (PDMS), polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polyester (PES), polymethylmethacrylate (PMMA), polycarbonate (PC), polyurethane (PU), or other suitable materials.

The display region DR includes a plurality of first control regions R1, a plurality of second control regions R2, and a plurality of third control regions R3. The first light-emitting units 10a, the second light-emitting units 20a, and the third light-emitting units 30a are respectively disposed on the first control regions R1, the second control regions R2, and the third control regions R3. In this embodiment, the first control regions R1 and the third control regions R3 are L-shaped, where the first control regions R1 and the third control regions R3 are L-shaped in different directions (for example, rotated 180 degrees). The second control regions R2 are in the shape of straight bars. The first control regions R1 and the third control regions R3 have similar shapes. A width W1 of each of the first control regions R1 and the third control regions R3 in a first direction D1 is twice a width W2 of each of the second control regions R2 in the first direction D1.

The first control regions R1 are arranged in a row in the first direction D1, and the third control regions R3 are also arranged in a row in the first direction D1. The first control regions R1 and the third control regions R3 are respectively located at a first side LS of the display region DR and a second side RS opposite to the first side LS. In this embodiment, in a second direction D2 perpendicular to the first direction D1, two rows of second control regions R2 are disposed between each first control region R1 and a corresponding third control region R3.

It should be noted that in FIG. 2A, a first microcontroller 100 is shown in a perspective manner, thereby showing a first connection pad 101 below the first microcontroller 100. With reference to FIG. 1 and FIG. 2A together, the first light-emitting units 10a are disposed on the first control regions R1 of the display region DR of the driver substrate DS. The plurality of first light-emitting units 10a are arranged in the first direction D1.

Each of the first light-emitting units 10a includes the first microcontroller 100, a plurality of first pixels 110, and a plurality of first supplementary pixels 120. In this embodiment, each of the first light-emitting units 10a further includes a plurality of first traces 112 and a plurality of first supplementary traces 122a. In this embodiment, in each of the first light-emitting units 10a, the first microcontroller 100, the first pixels 110, the first supplementary pixels 120, the first traces 112, and the first supplementary traces 122a are disposed on a corresponding one among the first control regions R1 of the display region DR. In this embodiment, the number of the first pixels 110 is greater than the number of the first supplementary pixels 120.

The first microcontroller 100 is electrically connected to the driver substrate DS through a plurality of first connection pads 101. The first microcontroller 100 includes a micro integrated circuit (micro IC). In some embodiments, the first microcontroller 100 is bonded to the driver substrate DS through a wafer bonding process. Conductive glue, solder, or other suitable conductive bonding components, for example, are included between the first microcontroller 100 and the first connection pads 101.

In some embodiments, the plurality of first microcontrollers 100 arranged in a column in the first direction D1 are connected in series via a circuit structure 130 extending in the first direction D1. The circuit structure 130 includes, for example, a plurality of signal lines. In FIG. 2A, the specific circuit layout in the circuit structure 130 is omitted.

Each of the first pixels 110 and the first supplementary pixels 120 includes a plurality of light-emitting elements (e.g., a red light-emitting diode R, a blue light-emitting diode B, and a green light-emitting diode G). The red light-emitting diode R, the blue light-emitting diode B, and the green light-emitting diode G are electrically connected to the driver substrate DS through pads (not shown separately in the figure). The red light-emitting diode R, the blue light-emitting diode B, and the green light-emitting diode G may be light-emitting diodes of any form, such as horizontal light-emitting diodes, vertical light-emitting diodes, or other types of light-emitting diodes.

In this embodiment, each of the first pixels 110 and the first supplementary pixels 120 further includes a redundant spare electrode RD. During a repair process, a repaired light-emitting diode may be bonded to the redundant spare electrode RD.

The first pixels 110 are arranged in two rows extending in the second direction D2 in the first direction D1. The first supplementary pixels 120 are arranged in two other rows extending in the second direction D2 in the first direction D1. The first microcontroller 100 is disposed between the first pixels 110 in the two rows in the first direction D1, and the first supplementary pixels 120 in the two other rows are at least partially aligned with the first pixels 110 in the two rows in the first direction D1. In each of the first light-emitting units 10a, a vertical projection of the first microcontroller 100 on the driver substrate DS does not overlap with vertical projections of the first pixels 110 and the first supplementary pixels 120 on the driver substrate DS.

In this embodiment, the first traces 112 are completely disposed in the display region DR and electrically connect the first microcontroller 100 to the first pixels 110 in the two rows. In this embodiment, each light-emitting element (e.g., the red light-emitting diode R, the blue light-emitting diode B, and the green light-emitting diode G) in each first pixel 110 is electrically connected to the first connection pad 101 of the first microcontroller 100 through one corresponding first trace 112.

In this embodiment, the first supplementary traces 122a electrically connect the first microcontroller 100 to the first supplementary pixels 120 in the two other rows. In the embodiment of FIG. 2A, at least a portion of the first supplementary traces 122a extend from the first microcontroller 100 in the display region DR through the first side LS of the display region DR to the peripheral region PR and then extends from the peripheral region PR through the first side LS of the display region DR again to the first supplementary pixels 120 in the two other rows in the display region DR. The first supplementary traces 122a are turned in the peripheral region PR so as to electrically connect the first supplementary pixels 120 and the first microcontroller 100. In the embodiment of FIG. 2A, the first supplementary traces 122a extend from the display region DR to the peripheral region PR, but the disclosure is not limited thereto. In other embodiments, the first supplementary traces 122a are completely disposed in the display region DR, as shown by first supplementary traces 122b of a first light-emitting unit 10b in FIG. 2C.

In some embodiments, one of the electrodes of each of the red light-emitting diode R, the blue light-emitting diode B, and the green light-emitting diode G in the first light-emitting unit 10a is electrically connected to the first microcontroller 100 through the first trace 112 or the first supplementary trace 122a, and the other electrode is electrically connected to a common electrode.

In this embodiment, by using the first microcontroller 100 to control the first pixels 110 and the first supplementary pixels 120, the circuit layout of the display device 1a may be simplified, and the adverse effects of the circuit on the display quality may be further reduced. To be specific, compared to the arrangement of arranging the first microcontroller 100 in the peripheral region PR, the first microcontroller 100 is disposed in the display region DR in this embodiment, so that trace lengths between the first microcontroller 100 and the first pixels 110 and between the first microcontroller 100 and the first supplementary pixels 120 may be reduced. In this embodiment, by arranging the microcontrollers (including the first microcontrollers 100, second microcontrollers 200, and third microcontrollers 300) in an alternating manner (for example, arranging in an alternating manner in the first direction D1 and/or the second direction D2), the traces may be better dispersed to make more efficient use of the circuit layout space. Further, the negative impact of the microcontrollers on a display screen may be lowered.

In this embodiment, by designing the first supplementary traces 122a and the first supplementary pixels 120, uneven pixel arrangement at an edge of the display region DR may be avoided. To be specific, without the design of the first light-emitting unit 10a, the first side LS of the display region DR may have a jagged edge (such as the left edge formed by connecting a row of second control regions R2 closest to the first side LS in FIG. 1). In order to prevent the jagged edges from affecting a display image, a bezel is usually set to cover the jagged edges. In this embodiment, the problem of jagged edges on the display screen may be avoided by using the first supplementary traces 122a and the first supplementary pixels 120 of the first light-emitting unit 10a. The aforementioned bezel for shielding the jagged edges may then be omitted, and the advantage of a narrow bezel is obtained.

Each of the third light-emitting units 30a includes the third microcontroller 300, a plurality of third pixels 310, and a plurality of third supplementary pixels 320. In this embodiment, each of the third light-emitting units 30a further includes a plurality of third traces (not shown separately in the figure) and a plurality of third supplementary traces (not shown separately in the figure). The third light-emitting unit 30a has an arrangement similar to that of the first light-emitting unit 10a in FIG. 2A (or the first light-emitting unit 10b in FIG. 2C). The difference therebetween is that the third supplementary pixels 320 of the third light-emitting unit 30a are disposed above the third pixels 310, while the first supplementary pixels 120 of the first light-emitting unit 10a (or the first light-emitting unit 10b in FIG. 2C) are disposed below the first pixels 110. Further, the third supplementary traces of the third light-emitting unit 30a may pass through the second side RS of the display region DR to extend into the peripheral region PR, or the third supplementary traces of the third light-emitting unit 30a may be completely disposed in the display region DR.

It should be noted that in FIG. 2B, the second microcontroller 200 is shown in a perspective manner, thereby showing a second connection pad 201 below the second microcontroller 200.
