[0030] Please refer to Figure 1 and Figure 2 . Figure 1 FIG. 1 is a schematic top view of a display device according to an embodiment of the present invention. Figure 2 Schematic diagram of the appearance of a display device according to an embodiment of the present invention in different usage scenarios. Figure 1 and Figure 2 As shown, the display device DI includes a display panel 100 and a processor 200, and the display device DI can be operated in multiple use scenarios, wherein the multiple use scenarios include (but are not limited to) Figure 2 The first usage scenario I, the second usage scenario II and the third usage scenario III are shown. The display device DI may be a wearable device (such as Figure 2 as shown) or vehicle display (as Figure 3As shown), or it can be applied to other suitable electronic devices, such as (but not limited to) smart phones, tablet computers, e-book readers, etc. The display panel 100 has a first area R1 and a second area R2, wherein the second area R2 surrounds the first area R1. The second area R2 has a plurality of curved areas RA and a corner area RB, and the corner area RB connects two of the plurality of curved areas RA. Among them, the curved area RA can be a unidirectional curved surface with zero Gaussian curvature, and the corner area RB can be a bidirectional curved surface with non-zero Gaussian curvature. The display surfaces of the curved area RA and the corner area RB are not parallel to the display surface of the first area R1. According to Figure 1 and Figure 2 In the embodiment shown, the second region R2 may include, for example, four curved regions RA and four corner regions RB. The four curved regions RA are respectively adjacent to the four sides of the first region R1, and the four corner regions RB are respectively adjacent to the four corners of the first region R1. Each corner region RB is located between and connected to two adjacent curved regions RA. The curved regions RA can be considered as sidewall regions connected to the first region R1, and the corner regions RB can be considered as transition regions adjacent to the sidewalls. However, the number of regions of the display panel 100 of the present invention is not limited to the above. In other embodiments, the number of regions can have various designs based on the actual product. Figure 3 The embodiments shown are examples. Figure 3 This is a schematic diagram of a display device installed in a vehicle according to another embodiment of the present invention. The display device DI can be installed on a vehicle VE, for example, on a dashboard below a windshield WS, a center console, a storage box (or a glove box), and / or any suitable device on the vehicle VE. The display panel 100 of the display device DI can be polygonal or irregular in shape and have multiple curved regions RA adjacent to multiple sides of a first region R1, but is not limited thereto.

[0031] The processor 200 is electrically connected to the display panel 100. The processor 200 may include, for example (but not limited to), a control unit, an integrated circuit chip, or a microcircuit chip (micro IC). Figure 1In the illustrated embodiment, the processor 200 may include a circuit board 210 and a chip 220, which are electrically connected to the display panel 100. The processor 200 is configured to: determine an operation mode corresponding to the first area R1, multiple curved areas RA, and corner area RB according to one of a plurality of usage scenarios; and control the first area R1, multiple curved areas RA, and corner area RB to operate in the determined operation mode. The plurality of usage scenarios may include a first usage scenario I, a second usage scenario II, and / or a third usage scenario III, and the operation mode may be a display mode or an off mode. In other words, the processor 200 may control each area of ​​the display panel 100 to execute a corresponding operation mode according to different usage scenarios, and may enable the first area R1, the curved area RA, and the corner area RB to have the same or different picture change rates. The usage scenarios of the display device DI and the operation modes of the corresponding areas will be further described in detail later.

[0032] The "image change rate" referred to in the present invention may include the visual image change frequency and the driving update frequency. The visual image change frequency refers to the image changes visible to the naked eye, including brightness changes, grayscale changes, and color changes. For example, the image can be changed by providing different data signals. The driving update frequency refers to the gate drive frequency of the region, which means the number of frames updated per second, such as (but not limited to) 60 Hz, 120 Hz, etc. In some embodiments, the range of variation of the update frequency of the first region R1 may be greater than the range of variation of the update frequency of the second region R2. For example, the update frequency range of the first region R1 may be 1 Hz to 120 Hz, and the update frequency range of the second region R2 may be 1 Hz to 60 Hz, but is not limited thereto.

[0033] The "display mode" referred to in the present invention refers to a state capable of displaying any grayscale. The display mode may include a high-frequency display mode and a low-frequency display mode. The low-frequency display mode may, for example (but not limited to), indicate providing a grayscale signal perceptible to the human eye. The "off mode" referred to in the present invention may indicate providing a low grayscale signal that is not perceptible to the human eye, providing a zero grayscale signal but with a non-zero update frequency, providing no signal, a low update frequency, a zero update frequency, or disabling the touch function. The low grayscale signal may, for example (but not limited to), refer to a set grayscale that is less than or equal to one-eighth of the total grayscale. Under the same area and the same time, the energy consumption of the off mode is lower than that of the display mode.

[0034] According to the first usage scenario I, the first area R1 can be operated in the off mode or the display mode, and the plurality of curved areas RA and the corner area RB can be operated in the display mode. The first usage scenario I includes, for example, the display device DI operating in the incoming call notification mode, the charging mode, the sensing mode, the music mode and / or the road running mode, but is not limited to the above. Specifically, Figure 2 The first usage scenario I is an example, which shows that the first usage scenario I is a situation where the display device DI operates in an incoming call reminder mode. Figure 2 As shown, in a first usage scenario I, the first region R1 can be activated in an off mode, and the multiple curved regions RA and corner regions RB surrounding the first region R1 can be activated in a display mode to display colors (indicated by the bottom of the grid). In some embodiments, the multiple curved regions RA and corner regions RB can display various colors in a flashing manner, such that the colors displayed by the multiple curved regions RA are the same as or different from the colors displayed by the corner regions RB. The displayed colors can be adjusted by the user to various colors.

[0035] according to Figure 2 In the embodiment shown, in the first usage scenario I, the curved area RA can also display the incoming call number NU in a ticker-shaped manner. For example, the digits of the incoming call number NU can be displayed in sequence in a ticker-shaped manner in one of the curved areas RA. For example, the incoming call number NU can be "0912345678". Figure 2 The first usage scenario I shows the curved area RA displaying the caller number NU as "091234" during a ticker display. Multiple curved areas RA can also display the caller number NU in a ticker display format surrounding the first area R1. In some embodiments, one of the curved areas RA can also display an incoming call icon. In other embodiments, the first area R1 can be simultaneously activated in display mode to display the incoming call icon, while the multiple curved areas RA and corner areas RB surrounding the first area R1 can display different colors depending on the caller. For example, the user can pre-set the display device DI so that the multiple curved areas RA and corner areas RB display different colors for calls from family, colleagues, and unknown calls.

[0036] According to the various call notification modes described above, in the first usage scenario I, since the first region R1 is in off mode or displays only the incoming call icon, while the second region R2 is required to display the incoming call notification, the image update rate of the second region R2 is greater than that of the first region R1. Specifically, the update frequency of the curved region RA can be greater than that of the first region R1, and the update frequency of the corner region RB can be greater than that of the first region R1. For example, the update frequency of the first region R1 can be 1 Hz, while the update frequency of the curved region RA and / or the corner region RB can be 30 Hz, but this is not limited to this.

[0037] Please refer to Figure 4 , which is a schematic diagram of the appearance of an embodiment of the display device of the present invention in the first usage scenario. The first usage scenario I in this embodiment is the case where the display device DI operates in the charging mode. Figure 4 In the illustrated embodiment, the first region R1 can be activated in a display mode to display a charging icon C1 or in an off mode without displaying any icon, and the multiple curved regions RA and corner regions RB surrounding the first region R1 can be activated in a display mode to present the completion of a task. In this embodiment, the above task may refer to charging the battery of the display device DI, for example (but not limited to) charging the battery of the display device DI via the charging line CHL. Figure 4 The states (i), (ii) and (iii) shown in FIG. 1 respectively represent different completion levels of charging of the display device DI. Figure 4 As shown in state (i), when the charging completion degree of the display device DI is 0%, the first region R1 displays the charging icon C1; Figure 4 As shown in state (ii), when the charging completion degree of the display device DI is greater than 0% and less than 100%, a portion of the curved area RA and / or the corner area RB displays a corresponding color (indicated by the bottom of the grid) according to the current charging completion degree. At this time, the curved area RA can also display a charging icon C2; Figure 4 As shown in state (iii), when the charging completion degree of the display device DI is 100%, the entire curved area RA and corner area RB of the second area R2 display color to indicate that charging is complete. In other words, the completion degree of a specific task (such as charging or sensing) can be represented by the degree to which the color displayed by the second area R2 surrounds the first area R1. When the charging task is completed, the multiple curved areas RA and corner areas RB display an image M1 surrounding the first area R1. According to the various charging modes described above, in the first usage scenario I, because the first area R1 only displays the charging icon C1 or is in the off mode, and the second area R2 needs to display the charging completion degree, the image change rate of the second area R2 is greater than the image change rate of the first area R1.

[0038] Please refer to Figure 5 , which is a schematic diagram of the appearance of another embodiment of the display device of the present invention in the first usage scenario. The first usage scenario I in this embodiment is the case where the display device DI operates in the sensing mode. Figure 5In the embodiment shown, the first area R1 can be activated in a display mode to display the sensing icon C3 or in an off mode without displaying any icon, and the multiple curved areas RA and corner areas RB surrounding the first area R1 can be activated in a display mode to present the completion of a task. The above-mentioned task in this embodiment may refer to sensing the user's physiological state, where the physiological state may be, for example, one of heart rate, blood pressure and blood oxygen concentration. Figure 5 The states (i), (ii) and (iii) shown in FIG. 1 respectively represent different degrees of completion of the physiological state sensed by the display device DI. Figure 5 As shown in state (i), when the sensing completion degree of the display device DI is 0%, the first region R1 displays the sensing icon C3, and the curved region RA may also display another sensing icon C4; Figure 5 As shown in state (ii), when the sensing completion degree of the display device DI is greater than 0% and less than 100%, a portion of the curved area RA and / or the corner area RB displays a color (indicated by the bottom of the grid) according to the current sensing completion degree; Figure 5 As shown in state (iii), when the sensing completion rate of the display device DI reaches 100%, the curved areas RA and corner areas RB of the entire second region R2 display a color to indicate sensing completion. In other words, when sensing is complete, the multiple curved areas RA and corner areas RB display an image M2 surrounding the first region R1. Based on the various sensing modes described above, in the first usage scenario I, since the first region R1 only displays the sensing icon C3 or is in off mode, while the second region R2 is required to display the sensing completion rate, the image change rate of the second region R2 is greater than that of the first region R1.

[0039] In some embodiments, when the first usage scenario I is when the display device DI is operating in music mode (not shown), the curved area RA and corner areas RB of the second region R2 can display one or more colors as ambient lighting. This ambient lighting can also flash or change color in time with the music, while the first region R1 can be operated in off mode or in display mode to display an image. In other embodiments, when the first usage scenario I is when the display device DI is operating in running mode (not shown), the curved area RA and corner areas RB of the second region R2 can display colors as warning lights. This warning light is more noticeable during nighttime exercise, while the first region R1 can be operated in off mode.

[0040] Please refer to Figure 2 ,according to Figure 2In the second usage scenario II shown, the first area R1, multiple curved areas RA, and corner areas RB are operated in display mode to display at least one image M3. The second usage scenario II includes, for example (but not limited to), a situation where the display device DI operates in picture mode. The first area R1 and the second area R2 jointly display an image to give the screen a sense of unity and reduce the visual impact of the border, thereby improving the display quality. In the second usage scenario II, since the first area R1 and the second area R2 are both used to display the image M3, these two areas need to have the same display quality. Therefore, the image change rate of the second area R2 is equal to or less than the image change rate of the first area R1. Specifically, the update frequency of the curved area RA is equal to the update frequency of the first area R1, and the update frequency of the corner area RB is equal to the update frequency of the first area R1. In some embodiments, the first region R1 may display the main part of the image, and the corner region RB may display the secondary part or background of the image. In this case, the update frequency of the corner region RB may be lower than the update frequency of the first region R1. For example, the update frequency of the first region R1 may be 120 Hz, and the update frequency of the corner region RB may be 60 Hz, but the present invention is not limited thereto.

[0041] according to Figure 2 In the third usage scenario III shown, multiple curved areas RA and corner areas RB are operated in the off mode, and the first area R1 is operated in the display mode to display text information TX. The third usage scenario III includes, for example (but not limited to), a case where the display device DI operates in the reading mode. Displaying text in the curved areas RA and corner areas RB would be inconvenient for the user to read, so only the first area R1 displays the text information TX. In the third usage scenario III, due to the higher requirements for the display quality of the first area R1, the image change rate of the first area R1 is greater than the image change rate of the second area R1. In other words, the update frequency of the first area R1 can be greater than the update frequency of the curved areas RA, and the update frequency of the first area R1 can be greater than the update frequency of the corner areas RB. For example, the update frequency of the first area R1 can be 60 Hz, and the update frequency of the corner areas RB can be 1 Hz, but is not limited thereto.

[0042] According to the aforementioned embodiments of the present invention, the processor 200 can control the first area R1, the curved area RA, and the corner area RB to operate in display mode or off mode respectively according to the first usage scenario I, the second usage scenario II, or the third usage scenario III, and can make the first area R1, the curved area RA, and the corner area RB have the same or different picture change rates, thereby achieving a power saving effect, and the various partition display states can meet different usage requirements.

[0043] Please refer to Figures 6A to 6C , and cooperate with Figure 1 . Figures 6A to 6CThe partial cross-sectional diagrams of some embodiments of the display device of the present invention respectively illustrate the detailed correspondence between the various film layers of the display device of some embodiments of the present invention. Figure 1 After the end portion 110E of the substrate 110 of the display device DI is bent to the back side S1, a portion of the cross-sectional structure obtained along the section line AA' can be referred to. Figure 6A 、 Figure 6B or Figure 6C The embodiment shown. Figures 6A to 6C and Figure 1 As shown, the display panel 100 includes a flexible substrate 110, and the substrate 110 may include a base layer 112 and a support layer 114, and the base layer 112 is disposed on the support layer 114. The processor 200 may include a circuit board 210 and a chip 220, and is disposed on an end portion 110E of the substrate 110. The circuit board 210 may be electrically connected to the display panel 100, for example, via a connection pad 202 disposed on the end portion 110E. In the corner region RB, the substrate 110 may further have a plurality of openings OP (shown in FIG. Figure 1 ) to facilitate bending of the corner region RB. The materials of the base layer 112 and the support layer 114 include, but are not limited to, polyimide (PI), polycarbonate (PC), polyethylene terephthalate (PET), or poly(methylmethacrylate) (PMMA).

[0044] like Figures 6A to 6C As shown, the end portion 110E, together with the circuit board 210 and chip 220 disposed thereon, can be bent to the back side S1 of the substrate 110. Specifically, the display panel 100 may include a support structure 102. The support structure 102 may be disposed between the end portion 110E of the substrate 110, which is bent to the back side S1, and the unbent portion of the substrate 110, to reduce the probability of breakage of the bent portion of the display panel 100. The display panel 100 may also include a display layer 120, an adhesive layer 130, and a cover layer 140. The display layer 120 is disposed on the front side S2 of the substrate 110, the adhesive layer 130 is disposed on the display layer 120, and the cover layer 140 is disposed on the adhesive layer 130 and connected to the display layer 120 through the adhesive layer 130.

[0045] according to Figure 6AIn the illustrated embodiment, the support structure 102 may include an adhesive layer 102a and a support portion 102b, and the adhesive layer 102a is located on opposite sides (e.g., upper and lower sides) of the support portion 102b, so that the end portion 110E and the unbent portion of the substrate 110 can be attached to the two sides of the support portion 102b through the adhesive layer 102a, and the support portion 102b can contact the bent portion 110P of the substrate 110. Figure 6B In the illustrated embodiment, the support structure 102 may include an adhesive layer 102a and a support portion 102b, and the end portion 110E and the unbent portion of the substrate 110 may be bonded to each other via the adhesive layer 102a. The support portion 102b is located on one side of the adhesive layer 102a and is closer to the bent portion 110P of the substrate 110 than the adhesive layer 102a. The support portion 102b may contact the bent portion 110P of the substrate 110. Figure 6C In the embodiment shown, the support structure 102 may only include the adhesive layer 102a. The design of the support structure 102 can reduce the probability of the bent portion of the display panel 100 being broken.

[0046] Please refer to Figure 7 , which is a top view of a first embodiment of the structure of the display device of the present invention. Figure 7 In the display device DI shown, the display panel 100 may include a gate driver GD disposed in at least one of the plurality of curved regions RA, and the gate driver GD is configured to provide a plurality of scan signals to the first region R1 and the second region R2. Figure 7 As shown, the display panel 100 may include a plurality of conductive lines CL (eg, scan lines). To simplify the drawings, Figure 7 Only a portion of the conductors CL is shown for schematic purposes. Similar simplified illustrations are also provided in the other top views below and will not be repeated. The gate driver GD electrically connects the conductors CL and the processor 200. The gate driver GD can provide multiple scan signals to the first region R1, multiple curved regions RA, and the corner region RB via the multiple conductors CL. The gate driver GD is, for example (but not limited to), a gate driver on panel (GOP), which can be disposed in a peripheral area (or non-display area) of the curved region RA. The first region R1, the curved region RA, and the corner region RB can each have a display area and a peripheral area. The peripheral area can be located on one side of the display area and near the edge of the display panel 100.
