Description

[0001] This application is a divisional application of the invention patent application with application date of July 18, 2019, application number 201910649673.2, and invention name “electronic device”. Technical Field

[0002] The invention relates to an electronic device, in particular to an electronic device which provides different voltages to electrodes in different regions. Background Art

[0003] In a self-luminous display device, each sub-pixel directly uses the corresponding light-emitting element to display the brightness level (gray scale). Therefore, compared with non-self-luminous display devices, it can have advantages such as high contrast, wide viewing angle, short response time, and thinness. In some applications, it can gradually replace non-self-luminous display devices and become the mainstream. Since the self-luminous display device displays the required image by controlling the brightness level of each light-emitting element, the driving voltage provided to each sub-pixel will affect the brightness of the light-emitting element.

[0004] In existing self-luminous display devices, in order to drive the light-emitting element of each sub-pixel, each sub-pixel needs to be electrically connected to the same voltage source through a corresponding voltage trace. However, as the distance between the sub-pixel and the voltage source varies, the equivalent resistance of the voltage trace will also vary. Therefore, when the voltage source provides the same driving voltage to the voltage trace, the sub-pixels electrically connected to the voltage traces with different equivalent resistances will receive different driving voltages, resulting in uneven image brightness of the display device. Summary of the invention

[0005] In view of this, some embodiments of the present invention provide an electronic device having a display area and a peripheral area adjacent to the display area. The electronic device includes a first electrode, a second electrode, a voltage source group, a first voltage trace and a second voltage trace. The first electrode is arranged in the display area, the second electrode is arranged in the display area, and the voltage source group is arranged in the peripheral area. The second voltage trace is electrically insulated from the first voltage trace. The voltage source group is electrically connected to the first electrode through the first voltage trace, and the voltage source group provides a first voltage to the first voltage trace. The voltage source group is electrically connected to the second electrode through the second voltage trace, the voltage source group provides a second voltage to the second voltage trace, and the first voltage is different from the second voltage. In a top view, the first voltage trace at least partially overlaps the second voltage trace. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Figure 1The figure shows a schematic top view of an electronic device according to a first embodiment of the present invention. The electronic device 1 includes a plurality of voltage traces 12, a plurality of regional electrodes 30, and a voltage source group 16, wherein one end of each voltage trace 12 can be electrically connected to the voltage source group 16, and the other end can be electrically connected to the corresponding regional electrode 30. The voltage traces 12 of the present embodiment can be, for example, divided into voltage traces 12A to 12F electrically insulated from each other, and the regional electrodes 30 can also be, for example, divided into regional electrodes 30A to 30F electrically insulated from each other, and for example, the voltage trace 12A is electrically connected to the corresponding regional electrode 30A, and the voltage trace 12B is electrically connected to the corresponding regional electrode 30B, and so on, but not limited thereto. Since the voltage source group 16 can provide different driving voltages to different voltage traces 12A to 12F, the regional electrodes 30A to 30F corresponding to different voltage traces 12A to 12F can each receive a corresponding driving voltage, so that the driving voltages provided to each regional electrode 30A to 30F can be independent of each other. The regional electrodes 30A-30F may be electrodes located in different regions and separated from each other. The regional electrodes 30A-30F may be, for example, regional electrodes from far to near the voltage source group 16 in sequence. In some embodiments, the width of the gap between adjacent regional electrodes 30A-30F is not limited to Figure 1 shown.

[0025] For example, when the equivalent resistances of the voltage traces 12A-12F are inconsistent, by providing different and independent driving voltages to different voltage traces 12A-12F, each of the regional electrodes 30A-30F can receive the required driving voltage respectively, for example, the regional electrodes 30A-30F can receive the same or nearly the same driving voltage regardless of the different distances from the voltage source group 16. The "same" driving voltage described herein is defined as a driving voltage within a range greater than 98% of a predetermined value and less than 102% of a predetermined value, and driving voltages outside the range are considered "different" driving voltages. Taking the voltage traces 12A to 12F as an example, the voltage traces 12A to 12F are electrically connected in sequence to the regional electrodes 30 from far to near the voltage source group 16. The equivalent resistance of the closer voltage trace 12F is smaller than the equivalent resistance of the farther voltage trace 12A. The driving voltage provided to the voltage trace 12A by the voltage source group 16 is higher than the driving voltage provided to the voltage trace 12F. The driving voltage received by the regional electrode 30A corresponding to the voltage trace 12A can be compensated to be close to or the same as the driving voltage received by the regional electrode 30F corresponding to the voltage trace 12F. Similarly, each regional electrode 30B to 30E corresponding to the voltage traces 12B to 12E can also receive the same or close driving voltage. Therefore, regardless of the distance between the regional electrodes 30A to 30F and the voltage source group 16, each regional electrode 30A to 30F can receive the same driving voltage. In this embodiment, the driving voltage provided to the voltage traces 12A to 12F by the voltage source group 16 can be, for example, a DC voltage, but is not limited thereto.

[0026] The voltage source group 16 may selectively have a plurality of voltage source output terminals 16A1-16F1, and each voltage source output terminal 16A1-16F1 is electrically connected to a corresponding voltage trace 12A-12F, respectively, to provide a plurality of independent and different driving voltages. In the present embodiment, the voltage source group 16 may be a single voltage source, and is controlled and output by a single control element 18, but is not limited thereto. In some embodiments, the voltage source group 16 may include at least two voltage sources, which are respectively controlled and output by at least one or more control elements 18. In some embodiments, the control element may be, for example, an integrated circuit.

[0027] The electronic device may include a display device, an antenna device, a sensing device, a splicing device or other suitable non-display device. The antenna device may be, for example, a liquid crystal antenna, but is not limited thereto. The splicing device may be, for example, a display splicing device or an antenna splicing device, but is not limited thereto. It should be noted that the electronic device may be any arrangement or combination of the foregoing, but is not limited thereto. The electronic device 1 below will take a display device as an example to illustrate the contents of the present invention, but the present invention is not limited thereto. In some embodiments, the top view shape of the electronic device 1 is not limited to a rectangle, but may also be other geometric shapes.

[0028] like Figure 1 As shown, the electronic device 1 of this embodiment may have a display area 1a and a peripheral area 1b disposed on the periphery of the display area 1a, but is not limited thereto. The peripheral area 1b of this embodiment is disposed on a side S1 of the display area 1a in the first direction D1. In other embodiments, the peripheral area 1b may also be disposed on a side of the display area 1a in a direction different from the first direction D1, but is not limited thereto. The electronic device 1 may include a plurality of sub-pixels 20 disposed in the display area 1a for displaying an image. In order to display clearly, Figure 1 The enlarged view on the right side illustrates one of the sub-pixels 20, but the present invention is not limited thereto. The regional electrodes 30A to 30F are respectively arranged in different areas in the display area 1a, and are used to electrically connect the sub-pixels 20 located in different areas to different voltage traces 12A to 12F. At least one sub-pixel 20 can be arranged in each area, that is, each regional electrode 30A to 30F can correspond to and electrically connect at least one sub-pixel 20. In the present embodiment, each regional electrode 30A to 30F can correspond to a plurality of sub-pixels 20, for example, a plurality of red, blue and green sub-pixels corresponding to each regional electrode are electrically connected to the same regional electrode. In other words, all sub-pixels 20 electrically connected to the same regional electrode 30A to 30F can receive a driving voltage from the corresponding voltage traces 12A to 12F. For example, sub-pixel 20-1 and sub-pixel 20-1' can be electrically connected to the same voltage trace 12A to receive the same driving voltage.

[0029] Taking a self-luminous display device as an example, each sub-pixel 20 may include a light-emitting unit 22 to generate the grayscale brightness required by the sub-pixel. In some embodiments, the light-emitting unit 22 may include an organic light-emitting diode or an inorganic light-emitting diode (such as a quantum dot light-emitting diode (such as QLED or QDLED), a sub-millimeter light-emitting diode (Mini-LED), a micro light-emitting diode (Micro-LED)). The light-emitting unit 22 may also selectively include fluorescence, phosphorescence, or other suitable materials, and the materials may be arranged and combined in any manner, but are not limited thereto. In the present embodiment, three sub-pixels 20 that can generate light of different colors may constitute a pixel PX, but are not limited thereto. In some embodiments, the composition of the pixel PX may be determined based on the arrangement of the sub-pixels 22, such as a matrix, PenTile, or other suitable methods.

[0030] In some embodiments, each sub-pixel 20 may further include a circuit 14 for electrically connecting the corresponding regional electrodes 30A~30F to the light-emitting unit 22 to drive the light-emitting unit 22. For example, the circuit 14 may include a driving transistor 24 and a switching transistor 26, wherein the driving transistor 24 is used to control the brightness of the light-emitting unit 22, and its source (drain) is electrically connected to the anode of the light-emitting unit 22, and the drain (source) is electrically connected to the voltage source group 16; the switching transistor 26 is used to control the switch of the driving transistor 24, and its drain (source) is electrically connected to the gate of the driving transistor 24, but is not limited to this. In addition, the electronic device 1 may also include a plurality of scan lines and a plurality of data lines for transmitting signals of the control circuit 14. The scan line is electrically connected to the gate of the corresponding switching transistor 26, and the data line is electrically connected to the source of the corresponding switching transistor 26. In some embodiments, the circuit 14 may not include the switching transistor 26, and the gate of the driving transistor 24 is electrically connected to the data line. In order to clearly display the electronic device 1 of this embodiment, Figure 1 The scanning lines and data lines are omitted, but the present invention is not limited thereto. Figure 1 As shown, in some embodiments, the circuit 14 may also include other transistors, or the transistors in the circuit 14 may also have other connection methods. In some embodiments, the light-emitting unit 22 may also be a light-emitting diode package capable of generating three different colors of light, and electrically connected to the three circuits 14, but not limited to this. In some embodiments, each sub-pixel 20 may also include a pixel electrode (not shown) for electrically connecting the circuit 14 to the light-emitting unit 22. In some embodiments, the pixel electrode may be, for example, an anode or cathode of the light-emitting unit 22 or other suitable electrodes. It is worth noting that the regional electrode 30 is used to electrically connect the circuit 14 to the voltage trace 12, and is different from the pixel electrode electrically connected between the circuit 14 and the light-emitting unit 22.

[0031] In some embodiments, the electronic device 1 may further include a driving element or circuit and a line for driving the sub-pixel, which are disposed in the peripheral area 1b. In some embodiments, the driving element, the line and the voltage source group 16 disposed in the peripheral area 1b may be bent toward the back side of the display device (i.e., the back side where no image is displayed) to improve the screen-to-body ratio of the display device.

[0032] In the present embodiment, the regional electrodes 30A-30F may be located in the display area 1a in the area from far to near the voltage source group 16, for example, arranged in sequence from the side S2 to the side S1 of the display area 1a along the first direction D1, but not limited to this, the arrangement direction may also be the second direction D2 or a direction different from the first direction D1 and the second direction D2. Each voltage trace 12A-12F of the present embodiment extends from the peripheral area 1b to the display area 1a, and is electrically connected to different regional electrodes 30A-30F. When the regional electrode 30 is not the electrode closest to the peripheral area 1b, the voltage trace 12 electrically connected to the more distant regional electrode 30 may pass through other regional electrodes 12 that are closer and not electrically connected thereto, for example, the voltage trace 12A may pass through the regional electrodes 30B-30F that are not electrically connected thereto. Therefore, the lengths of the voltage traces 12A-12F extending to different regional electrodes 30A-30F are different, resulting in inconsistent equivalent resistances of the voltage traces 12A-12F.

[0033] According to formula (1): R=P×L / (W×H), the equivalent resistance of the voltage traces 12A-12F can be calculated, where R is the equivalent resistance of the corresponding voltage traces 12A-12F, P is the resistivity of the corresponding voltage traces 12A-12F, L is the length of the corresponding voltage traces 12A-12F (for example, the extended length measured when the voltage traces 12A-12F have the same cross-sectional area in the top-view direction VD), W is the line width of the corresponding voltage traces 12A-12F (for example, the cross-sectional width of the voltage traces 12A-12F measured along a direction perpendicular to the extension direction and parallel to the horizontal direction), and H is the line height of the corresponding voltage traces 12A-12F (for example, the cross-sectional height of the voltage traces 12A-12F measured along the top-view direction VD). The horizontal direction can be, for example, the first direction D1, the second direction D2, or a direction parallel to the plane formed by the first direction D1 and the second direction D2. For example, when each voltage trace 12A-12F has the same surface resistance, that is, the voltage traces 12A-12F have the same resistivity, the same line height and the same line width, the voltage traces 12A-12F will have different equivalent resistances, and will decrease in sequence, but this is not a limitation. It is worth noting that by providing different driving voltages to different voltage traces 12A-12F through the voltage source group 16, for example, respectively providing driving voltages from high to low to the voltage traces 12A-12F with equivalent resistances from high to low, the driving voltage received by the sub-pixel 20 (such as the sub-pixel 20-1 or 20-1') farther from the voltage source group 16 can be appropriately compensated to be consistent or nearly consistent with the driving voltage received by the sub-pixel 20 (such as the sub-pixel 20-2) closer to the voltage source group 16, thereby reducing the problem of different driving voltages received by the sub-pixel 20 due to different distances from the voltage source group 16, so that the electronic device 1 can have uniform brightness performance.

[0034] It is worth mentioning that, since the sub-pixel 20-1 electrically connected to the regional electrode 30A in this embodiment is farther from the voltage source group 16 than the sub-pixel 20-2 electrically connected to the regional electrode 30F, the voltage trace 12A electrically connected from the voltage source group 16 to the sub-pixel 20-1 will be longer than the voltage trace 12F electrically connected from the voltage source group 16 to the sub-pixel 20-2. In the case of having the same surface resistance, the equivalent resistance of the voltage trace 12A will be greater than the equivalent resistance of the voltage trace 12F. For example, the voltage source group 16 can provide a voltage V1 to the voltage trace 12A and provide a voltage V2 to the voltage trace 12F, and the voltage V1 is greater than the voltage V2, but because the equivalent resistance of the voltage trace 12A is greater than the equivalent resistance of the voltage trace 12F, all sub-pixels 20 electrically connected to the regional electrode 30A and the regional electrode 30F can receive a consistent voltage. For example, when the voltage received by all sub-pixels 20 of the electronic device 1 is expected to be 7V, the voltage V1 provided by the voltage source group 16 may be 9.0V, and the voltage V2 may be 7.5V, but is not limited thereto. Different driving voltages V1 and V2 are provided through the voltage trace 12A and the voltage trace 12F, respectively, so that the voltages received by the sub-pixel 20-1 and the sub-pixel 20-2 are nearly the same, thereby improving the uniformity of the image brightness of the display device.

[0035] In the present embodiment, the number of voltage traces 12A-12F extending from the peripheral region 1b to the same regional electrode 30A-30F may be two, but is not limited thereto. For example, the electronic device 1 includes two voltage traces 12A, electrically connected to the sub-pixel 20 of the same regional electrode 30A, and so on. In this case, the voltage source group 16 may also have a plurality of voltage source output terminals 16A2-16F2, and the voltage source output terminals electrically connected to the same regional electrode 30A-30F provide the same driving voltage. In the present embodiment, each voltage source output terminal 16A2-16F2 provides the same driving voltage as the corresponding voltage source output terminal 16A1-16F1. In some embodiments, the number of voltage traces 12A-12F electrically connected to the regional electrodes 30A-30F may also be one or more than two. In the present embodiment, the voltage traces 12A-12F may extend to the left and right sides of the corresponding regional electrodes 30A-30F, respectively. In other embodiments, the voltage traces 12A-12F may also be arranged on the same side, and this is not limited thereto. It is worth noting that in this embodiment, the regional electrodes 30A-30F away from the peripheral area 1b do not contact the two side edges S3 and S4 of the display area 1a arranged in the second direction D2, and the regional electrodes 30B-30F located between the regional electrode 30A and the peripheral area 1b may have concave side edges relative to the peripheral area 1b, but the present invention is not limited thereto. The size (i.e., the number of sub-pixels corresponding to one regional electrode 30A-30F) and shape of the regional electrodes 30A-30F may be determined according to the taste of the display device. In some embodiments, the size of the regional electrodes 30A-30F may be determined by whether the human eye can recognize whether the brightness displayed by the sub-pixels 20 of the same regional electrode 30A-30F is uniform, but this is not limited thereto.

[0036] Figure 1 The regional electrode 30 shown on the left side is only for illustration and does not represent the actual shape of the regional electrode 30. Figure 1 As shown in the enlarged view on the right, the regional electrode 30 may be formed by a plurality of strip electrodes, for example, but is not limited thereto. In some embodiments, the voltage traces 12A to 12F may not extend into the display area 1a, but the regional electrode 30 may extend outside the display area 1a to be electrically connected to the corresponding voltage traces 12A to 12F. In this embodiment, the electronic device 1 may further include a common voltage line 32 electrically connecting the cathodes of the light-emitting units 22 of all sub-pixels 20.

[0037] The electronic device is not limited to the above-mentioned embodiment, and may have different variant embodiments. To simplify the description, the different variant embodiments below will use the same reference numerals as the first embodiment to mark the same elements. To facilitate comparison of the differences between the first embodiment and the different variant embodiments, the differences between the different variant embodiments will be highlighted below, and the repeated parts will not be described in detail.

[0038] Figure 2 FIG. 1 is a schematic top view of a structure of a portion of sub-pixels, a portion of regional electrodes, and a portion of voltage wirings of an electronic device according to a second embodiment of the present invention. For the sake of clarity, Figure 2 Only part of the regional electrodes, part of the sub-pixels and part of the voltage wiring are displayed, and the voltage source group is omitted, but not limited to this. Figure 1 The difference of the first embodiment shown is that the sub-pixels 20 electrically connected to the same regional electrodes 30A to 30F and corresponding to different colors can be electrically connected to different voltage traces. Taking the corresponding regional electrode 30A as an example, the sub-pixel 20 can be divided into a plurality of sub-pixels 20R, a plurality of sub-pixels 20G, and a plurality of sub-pixels 20B, wherein the light-emitting units 22 of the sub-pixels 20R, the sub-pixels 20G, and the sub-pixels 20B can respectively generate different colors, such as red, green, and blue, respectively, but not limited thereto. The regional electrode 30A can also be divided into regional electrodes 30AR, 30AG, and 30AB that are electrically insulated from each other. The regional electrodes 30AR, 30AG, and 30AB are electrically connected to the sub-pixels 20R, the sub-pixels 20G, and the sub-pixels 20B, respectively. Furthermore, the voltage trace 12A extending to the regional electrode 30A can also be divided into voltage traces 12AR, 12AG, and 12AB that are electrically insulated from each other, wherein the voltage traces 12AR, 12AG, and 12AB are electrically connected to the regional electrodes 30AR, 30AG, and 30AB, respectively. Therefore, the sub-pixels 20R, 20G, and 20B can be electrically connected to the voltage source group through the voltage traces 12AR, 12AG, and 12AB, respectively. In other words, the sub-pixels 20R, sub-pixels 20G, and sub-pixels 20B located in the same region (corresponding to the same regional electrode 30A) can receive independent driving voltages, respectively. For example, the voltage source output terminal in the voltage source group that is electrically connected to the voltage trace 12A can be divided into three voltage source output terminals, which are electrically connected to the voltage traces 12AR, 12AG, and 12AB, respectively. In some embodiments, the voltage trace 12A receiving a single driving voltage may extend to the region corresponding to the regional electrode 30A, and be electrically connected to the voltage traces 12AR, 12AG, and 12AB through a corresponding circuit (not shown), so that the driving voltage can be divided into three driving voltages through the corresponding circuit (not shown), and provided to the voltage traces 12AR, 12AG, and 12AB respectively, so that the sub-pixel 20R, the sub-pixel 20G, and the sub-pixel 20B can receive different driving voltages. When the light-emitting unit 22 of the sub-pixel 20R, the light-emitting unit 22 of the sub-pixel 20G, and the light-emitting unit 22 of the sub-pixel 20B need to be driven by different driving voltages, the design of this embodiment can help to separately drive the sub-pixels 20R, 20G, and 20B of different colors to improve the image quality of the display device. In some embodiments, the structure of other regional electrodes may also be the same as the structure in the regional electrode 30A.

[0039] Figure 3 FIG. 1 is a top view of an electronic device according to a third embodiment of the present invention. Figure 3 Only the voltage traces and regional electrodes are shown, but the present invention is not limited thereto. The voltage traces 312A-312F and the regional electrodes 330A-330F of the electronic device 3 of the present embodiment may be formed by the same conductive layer M1. The difference between the present embodiment and the previous embodiment is that the voltage traces 312A-312F are in the peripheral area 1b. In the present embodiment, at least one of the voltage traces 312A-312F may extend along the periphery of the display area 1a to the corresponding regional electrodes 330A-330F, for example, the voltage traces 312B and 312D extend along the side S4 to the corresponding regional electrodes 330B and 330D, and the regional electrodes 330E and 330F close to the voltage source group (not shown) are electrically connected to the voltage traces 312E and 312F at the side S1.

Other regional electrodes 330C and 330D may also be changed accordingly, but are not limited thereto. In some embodiments, the conductive layer M1 may be formed of metal or other suitable materials. In some embodiments, the voltage traces 312A-312F and the regional electrodes 330A-330F may also be formed of different conductive layers, but have the same configuration as the third embodiment, wherein different conductive layers may include the same material or different materials.
