[0076] The following are specific embodiments to illustrate the implementation manners of the present disclosure. Those skilled in the art can easily understand other advantages and effects of the present disclosure from the content disclosed in this specification. The present disclosure can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified and changed according to different viewpoints and applications without departing from the spirit of the present disclosure.

[0077] It should be noted that in the present disclosure, unless otherwise specified, having an "a" element does not limit to having only one such element, but may have one or more such elements. Furthermore, the ordinal numbers such as "first" and "second" used in the specification and claims are used to modify the elements of the claims, and do not themselves imply or represent that the claimed element has any previous ordinal number, nor does it represent the order of one claimed element and another claimed element, or the order in the manufacturing method. The use of these ordinal numbers is only to clearly distinguish one claimed element with a certain name from another claimed element with the same name.

[0078] Throughout this specification and the claims, certain terms are used to refer to particular elements. Those skilled in the art will understand that electronic device manufacturers may refer to the same elements by different names. This document does not intend to distinguish between elements that perform the same function but have different names. In the following specification and claims, terms such as "comprising", "including", "having" are open-ended terms and should therefore be interpreted to mean "including but not limited to...". Thus, when the description of this disclosure uses the terms "comprising", "including" and / or "having", it specifies the presence of the corresponding features, regions, steps, operations and / or components, but does not exclude the presence of one or more corresponding features, regions, steps, operations and / or components.

[0079] In this disclosure, the terms "about", "approximately", "substantially", "generally" typically mean within a range of 10%, 5%, 3%, 2%, 1% or 0.5% of a given value. The given quantity is an approximate quantity, that is, the meaning of "about", "approximately", "substantially", "generally" may still be implied even without specifically stating "about", "approximately", "substantially", "generally". In addition, the expressions "ranging from a first value to a second value", "ranging between a first value and a second value" mean that the range includes the first value, the second value and other values therebetween.

[0080] Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by those skilled in the art to which this disclosure pertains. It is understood that these terms, such as those defined in commonly used dictionaries, should be interpreted to have a meaning consistent with the relevant art and the background or context of this disclosure, and should not be interpreted in an idealized or overly formal manner unless specifically defined herein.

[0081] In addition, relative terms such as "below" or "bottom" and "above" or "top" may be used in the embodiments to describe the relative relationship of one element of the drawing to another element. It is understood that if the device in the drawing is flipped so that it is upside down, the element described on the "below" side will become the element on the "above" side. When a corresponding component (such as a film layer or region) is referred to as "on another component", it may be directly on another component, or there may be other components between them. On the other hand, when a component is referred to as "directly on another component", there are no components between them. In addition, when a component is referred to as "on another component", there is an up-and-down relationship between the two in the top-down view direction, and this component may be above or below the other component, and this up-and-down relationship depends on the orientation of the device.

[0082] In the present disclosure, the measurement methods of distance, width, length, and thickness can be obtained by measuring with an optical microscope, and the distance, width, length, and thickness can be measured from the cross-sectional images in an electron microscope, but the present disclosure is not limited thereto. Additionally, there may be a certain error between any two values or directions being compared. If the first value is equal to the second value, it implies that there may be an error of approximately 10% between the first value and the second value; if the first direction is perpendicular to the second direction, the angle between the first direction and the second direction can be between 80 degrees and 100 degrees; if the first direction is parallel to the second direction, the angle between the first direction and the second direction can be between 0 degrees and 10 degrees.

[0083] It should be noted that the technical solutions provided in different embodiments below can be mutually replaced, combined, or used in combination to form another embodiment without violating the spirit of the present disclosure.

[0084] The display device of the present disclosure can be a non-self-luminous display device or a self-luminous display device, such as a liquid crystal display (Liquid Crystal Display), a cholesteric liquid crystal display (Cholesteric Liquid Crystal Display), an electrophoretic display (Electro-Phoretic Display), an organic light emitting diode display (organic light emitting diode Display), a light emitting diode display (light emitting diode Display), but not limited thereto. The display device may include light emitting diodes, light conversion layers, or other suitable materials, or combinations thereof, but not limited thereto. The light emitting diodes may include, for example, organic light emitting diodes (organic light emitting diode, OLED), mini light emitting diodes (mini LED), micro light emitting diodes (micro LED), or quantum dot light emitting diodes (quantum dot LED, which may include QLED, QDLED), but not limited thereto.

[0085] Figure 1 Schematic diagram of a display device according to an embodiment of the present disclosure. Figures 2A to 2C is Figure 1 partial enlarged view of Figure 2D is Figure 2A partial enlarged view of . Among them, for convenience of illustration, some elements are omitted in the figure.

[0086] In an embodiment of the present disclosure, as Figure 1As shown, the display device may include: a substrate Sub, including an active area AA and a peripheral area B, the peripheral area B surrounding the active area AA, wherein the active area AA includes a first area A1 and a second area A2; a first driving circuit C1 disposed adjacent to the first area A1 of the active area AA; a second driving circuit C2 disposed adjacent to the second area A2 of the active area AA; a plurality of first scan lines SL1 extending in a first direction X within the active area AA, wherein the first scan lines SL1 are electrically connected to the first driving circuit C1; and a plurality of second scan lines SL2 extending in the first direction X within the active area AA, wherein the second scan lines SL2 are electrically connected to the second driving circuit C2; wherein the first scan lines SL1 and the second scan lines SL2 are arranged in an interleaved manner, and in the first direction X, the active area AA is located between the first driving circuit C1 and the second driving circuit C2.

[0087] In the present disclosure, the active area AA may include a plurality of display units. More specifically, the range of the active area AA may be defined by the edges of the display units. For example, the upper edge e1 parallel to the first direction X in the active area AA may be defined by the line connecting the upper left corner of the leftmost and uppermost display unit to the upper right corner of the rightmost and uppermost display unit in the active area AA, and the length of the edge e1 may be the distance between the upper left corner of the leftmost and uppermost display unit and the upper right corner of the rightmost and uppermost display unit in the first direction X. Among them, the length of at least one of the first scan lines SL1 and the second scan lines SL2 is greater than 3 / 4 of the length of the edge e1, but the present disclosure is not limited thereto.

[0088] In an embodiment of the present disclosure, as Figures 2A to 2C shown, the display device may include a plurality of data lines DL extending in a second direction Y within the active area AA, wherein the first direction X is different from the second direction Y. The plurality of data lines DL and the plurality of first scan lines SL1 and the plurality of second scan lines SL2 are interleaved to form a plurality of display units. More specifically, as Figure 2A and Figure 2B shown, the plurality of data lines DL and the plurality of first scan lines SL1 are interleaved to form a plurality of first display units P1. More specifically, the range of a first display unit P1 may be defined as the range enclosed by the center line of a data line DL to the center line of another adjacent data line DL and the center line of a first scan line SL1 to the center line of another adjacent first scan line SL1. The first display units P1 are disposed in the first area A1 of the active area AA, wherein the first display units P1 are electrically connected to the first scan lines SL1 respectively and are electrically separated from the second scan lines SL2. As Figure 2B and Figure 2CAs shown, multiple data lines DL and multiple second scan lines SL2 intersect to form multiple second display units P2. Similar to the way the range of the first display unit P1 is defined, specifically, the range of a second display unit P2 can be defined by the center lines of two adjacent data lines DL and the center lines of two adjacent second scan lines SL2. The second display unit P2 is disposed in the second area A2 of the active area AA. Among them, the second display unit P2 is electrically connected to the second scan line SL2 respectively and is electrically separated from the first scan line SL1. According to the description of this paragraph, the upper left corner of a display unit can be the intersection of the center line of the data line DL on the left side of the display unit and the center line of the scan line on the upper side of the display unit, and the upper right corner of the display unit can be the intersection of the center line of the data line DL on the right side of the display unit and the center line of the scan line on the upper side of the display unit. The definition methods of other endpoints of the display unit can be inferred by analogy.

[0089] In the present disclosure, signals are transmitted to the first display unit P1 through the first scan line SL1 electrically connected to the first driving circuit C1, and signals are transmitted to the second display unit P2 through the second scan line SL2 electrically connected to the second driving circuit C2, so as to achieve the effect of partition display of the first display unit P1 located in the first area A1 and the second display unit P2 located in the second area A2 in the same display device. In other words, in the same display device, the first display unit P1 located in the first area A1 and the second display unit P2 located in the second area A2 can display different patterns respectively. When there are defects in the components or display units in one of the first area A1 and the second area A2 of the active area AA, the display units in the other area can still display images. Therefore, the present disclosure can be used, for example, in aircraft or other high-order display devices. In addition, since the display device of the present disclosure does not achieve the effect of partition driving by splicing or assembling display panels, there will be no non-display area or discontinuous picture between the first area A1 and the second area A2.

[0090] In an embodiment of the present disclosure, as Figure 1 shown, in the first direction X, the first area A1 of the active area AA is located between the second area A2 of the active area AA and the first driving circuit C1, and the second area A2 of the active area AA is located between the first area A1 of the active area AA and the second driving circuit C2. In an embodiment of the present disclosure, as Figure 1 shown, the first driving circuit C1 and the second driving circuit C2 can be respectively disposed in the peripheral area B of the substrate Sub, but the present disclosure is not limited thereto. In other implementation forms, the first driving circuit C1 can be selectively disposed on other substrates adjacent to the first area A1, and the second driving circuit C2 can be selectively disposed on other substrates adjacent to the second area C2.

[0091] In an embodiment of the present disclosure, as Figure 2A and Figure 2BAs shown, one of the first display units P1 may include: a first transistor 11; and a first pixel electrode 12, wherein the first transistor 11 is electrically connected to the first pixel electrode 12. More specifically, as Figure 2D shown, the first transistor 11 may include: a first gate 111, a first semiconductor layer 112, a first electrode 113, and a second electrode 114, wherein the first gate 111 is electrically connected to one of the first scan lines SL1 and overlaps with a part of the first semiconductor layer 112.

[0093] In an embodiment of the present disclosure, as Figure 2A shown, the first pixel electrode 12 has a first edge 12e1 and a second edge 12e2, the first edge 12e1 is opposite to the second edge 12e2, wherein one of the first scan lines SL1 is disposed adjacent to the first edge 12e1 and is electrically connected to the first transistor 11 corresponding to the first pixel electrode 12, and one of the second scan lines SL2 is disposed adjacent to the second edge 12e2. Similarly, as Figure 2CAs shown, the second pixel electrode 22 has a first edge 22e1 and a second edge 22e2, the first edge 22e1 being opposite to the second edge 22e2. Among them, one of the second scan lines SL2 is disposed adjacent to the second edge 22e2 and is electrically connected to the second transistor 21 corresponding to the second pixel electrode 22, and one of the first scan lines SL1 is disposed adjacent to an edge 22e1.

The branch portions 111A and 111B can improve the driving effect of the first transistor 11. Similarly, as Figure 2C shown, the second gate 211 may also have branch portions (such as 211A and 211B) as Figure 2D shown, which will not be elaborated herein. In the present disclosure, as Figure 2D shown, the first gate 111 takes the top-gate structure as an example, but the present disclosure is not limited thereto. In other implementation forms, the first gate 111 may also be a bottom-gate structure.

[0095] In an embodiment of the present disclosure, as Figure 2A shown, the display device may include a second electrostatic protection structure 23, which is disposed in the peripheral area B of the substrate Sub (as Figure 1 shown) and is electrically connected to the second scan line SL2. In an embodiment of the present disclosure, as Figure 1 and Figure 2A shown, in the first direction X, the second electrostatic protection structure 23 is located between the first driving circuit C1 and the first area A1. In an embodiment of the present disclosure, as Figure 2A shown, the second electrostatic protection structure 23 may include diodes connected in series with each other, but the present disclosure is not limited thereto. A plurality of serially connected diodes can be used to release the static charges generated by the display device, avoiding damage to the components in the display device caused by the accumulation of static charges. In this embodiment, Figure 2A the second electrostatic protection structure 23 shown takes 2 serially connected diodes as an example, but the present disclosure is not limited thereto. In other implementation forms, the number of serially connected diodes can be adjusted according to requirements, and the number of diodes in each second electrostatic protection structure 23 can be the same or different.

[0096] Similarly, as Figure 2C shown, the display device may include a first electrostatic protection structure 13, whose structure and function may be the same as those of the aforementioned second electrostatic protection structure 23, and will not be repeated herein.

[0097] In the present disclosure, the first scan line SL1 and the second scan line SL2 may be on the same layer or different layers, and the materials of the first scan line SL1 and the second scan line SL2 may each include a metal material, a metal oxide material, an alloy thereof, or a combination thereof.

In the present disclosure, the materials of the first gate 111 and the second gate 211 may be the same or different, and the first gate 111 and the second gate 211 may each include a metal material, a metal oxide material, an alloy thereof, or a combination thereof.

Figure 4D is Figure 4B partial enlarged view of. Wherein, Figure 3 the display device of Figure 1 is similar, except for the following differences. In addition, for ease of illustration, some elements are omitted in the figures.

[0099] In an embodiment of the present disclosure, as Figure 3As shown, the active area AA of the substrate Sub may include a third area A3 located between the first area A1 and the second area A2. The display device further includes: a plurality of third scan lines SL3 extending along the first direction X in the active area AA, wherein the third scan lines SL3 are electrically connected to the first drive circuit C1, but the present disclosure is not limited thereto. In some embodiments, the third scan lines SL3 may be electrically connected to the second drive circuit C2.

[0100] In one embodiment of the present disclosure, Figures 4A to 4C As shown, in the second direction Y, one of the first scan lines SL1 is located between one of the second scan lines SL2 and one of the third scan lines SL3, and the distance D1 between the one of the first scan lines SL1 and the one of the third scan lines SL3 is smaller than the distance D2 between the one of the first scan lines SL1 and the one of the second scan lines SL2. In more detail, in the second direction Y, the second scan lines SL2 and the third scan lines SL3 are respectively disposed on both sides of the first scan line SL1, wherein the third scan line SL3 adjacent to the first scan line SL1 has a distance D1 from the first scan line SL1, and the second scan line SL2 adjacent to the first scan line SL1 has a distance D2 from the first scan line SL1, wherein the distance D1 is smaller than the distance D2.

[0102] In one embodiment of the present disclosure, Figures 4A to 4C As shown, a plurality of data lines DL and a plurality of third scan lines SL3 are interlaced to form a plurality of third display units P3, and the third display units P3 are arranged in the action area AA (eg Figure 3 The first display unit P1 is electrically connected to the first scan line SL1, and is electrically separated from the second scan line SL2 and the third scan line SL3; the second display unit P2 is electrically connected to the second scan line SL2, and is electrically separated from the first scan line SL1 and the third scan line SL3; the third display unit P3 is electrically connected to the third scan line SL3, and is electrically separated from the first scan line SL1 and the second scan line SL2.

[0103] The present disclosure transmits signals to a first display unit P1 through a first scan line SL1 electrically connected to a first driving circuit C1, transmits signals to a second display unit P2 through a second scan line SL2 electrically connected to a second driving circuit C2, and transmits signals to a third display unit P3 through a third scan line SL3 electrically connected to the first driving circuit C1, thereby achieving the effect of partitioned display of the first display unit P1 located in a first region A1, the second display unit P2 located in a second region A2, and the third display unit P3 located in a third region A3 in the same display device. In other words, in the same display device, the first display unit P1 located in the first region A1, the second display unit P2 located in the second region A2, and the third display unit P3 located in the third region A3 can display different patterns respectively. When there are defects in components or display units in one or both of the first region A1, the second region A2, and the third region A3 in the active area AA, the display units in the other region or the other two regions can still display images.

[0104] In this embodiment, as Figure 3 shown, the third scan line SL3 is exemplified by being electrically connected to the first driving circuit C1. However, in other embodiments, the third scan line SL3 can be electrically connected to the second driving circuit C2, so that signals can be transmitted from the second driving circuit C2 to the third display unit P3 via the third scan line SL3 (as Figure 4B shown).

[0105] In an embodiment of the present disclosure, as Figure 4B shown, one of the third display units P3 may include: a third transistor 31; and a third pixel electrode 32, wherein the third transistor 31 is electrically connected to the third pixel electrode 32.
