The non-display area (bezel area) of existing display panels is too wide, which cannot meet the market demand for smaller bezels.
By optimizing the layout and wiring design of the display panel, the width of the non-display area is reduced. This includes arranging multiple buffer circuits and clock lines in the first and second directions, and separating the clock lines in the cross direction. Combined with the design of integrated logic circuits and signal lines, the space occupied by the non-display area is reduced.
This reduces the width of the non-display area of the display panel, improving the aesthetics and space utilization of electronic devices.

[0047] In the specification, the expressions "on" the first component (or area, layer, part, section, etc.) is "on" the second component, or "connected" or "combined" with the second component, indicate that the first component is directly on the second component, the first component is directly connected or combined with the second component, or that the third component is placed between the first component and the second component.
[0048] The same reference numerals denote the same components. Furthermore, in the drawings, for the sake of the effectiveness of the description of the technical content, the thickness, scale, and dimensions of the components are exaggerated. The term "and / or" includes one or more combinations of the related elements in each of them.
[0049] Although the terms “first,” “second,” etc., may be used to describe various components, these components should not be construed as being limited by these terms. These terms are used only to distinguish one component from another. For example, without departing from the scope and spirit of this disclosure, a first component may be referred to as a second component, and similarly, a second component may be referred to as a first component. The articles “a,” “an,” and “the” are singular because they have a single indicator, but the use of the singular form in the specification should not preclude the existence of more than one indicator.
[0050] Furthermore, the terms "below," "under," "above," and "over" are used to describe the relational relationship of the components shown in the accompanying drawings. These terms are relative concepts and are described relative to the directions indicated in the drawings.
[0051] It will be understood that the terms “comprising,” “including,” “having,” etc., indicate the presence of the features, quantities, steps, operations, elements or components described in the specification, or combinations thereof, without excluding the possibility of the presence or addition of one or more other features, quantities, steps, operations, elements or components, or combinations thereof.
[0052] The terms "component" and "unit" refer to software or hardware components that perform a specific function. For example, a hardware component may include a field-programmable gate array (FPGA) or an application-specific integrated circuit (ASIC). A software component may refer to executable code in addressable storage media and / or data used by the executable code. Therefore, a software component can be, for example, an object-oriented software component, a class component, and a task component, and may include processes, functions, attributes, programs, subroutines, program code segments, drivers, firmware, microcode, circuits, data, databases, data structures, tables, arrays, or variables.
[0053] Unless otherwise defined, all terms used in this specification (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains. Furthermore, terms (such as those defined in common dictionaries) shall be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and shall not be interpreted in an idealized or overly formal sense unless expressly defined herein.
[0054] In the following description, embodiments of the present disclosure will be described with reference to the accompanying drawings.
[0055] Figure 1A This is a perspective view of an electronic device DD according to an embodiment of the present disclosure. Figure 1B This is a block diagram of an electronic device DD according to an embodiment of the present disclosure. Figure 2 This is a plan view of an electronic device DD according to an embodiment of the present disclosure.
[0056] Reference Figure 1A and Figure 1B The electronic device DD can be a device activated by an electrical signal. Besides large electronic devices such as televisions, monitors, or billboards, the electronic device DD can also be used in small to medium-sized electronic devices such as personal computers, laptops, personal digital terminals, car navigation units, game consoles, portable electronic devices, and cameras. Furthermore, these are presented only as examples. It should be noted that aspects of this disclosure are not limited to the disclosed types of electronic devices, and that this disclosure can be applied to other electronic devices as long as they do not depart from the concept of this disclosure. Figure 1A The electronic device DD shown in the image may be a monitor.
[0057] The electronic device DD outputs various information through the display module 140 in the operating system. When the processor 110 executes an application stored in the memory 120, the display module 140 provides application information to the user through the display panel DP. The processor 110 can be one or more processors that can execute method steps such as application execution individually, collectively, or partially collectively. For example, but without limitation, in the operation method, two processors can jointly execute a step, while a third processor executes a second step.
[0058] Processor 110 receives external input via input module 130 or sensor module 161 and executes the application corresponding to the external input. For example, when a user selects the camera icon displayed on the display panel DP, processor 110 receives user input via input sensor 161-2 and activates camera module 171. Processor 110 transmits image data corresponding to the captured image obtained by camera module 171 to display module 140. Display module 140 can display the image corresponding to the captured image via display panel DP.
[0059] As another example, when authentication of personal information is performed in display module 140, fingerprint sensor 161-1 obtains the input fingerprint information as input data. Processor 110 compares the input data obtained by fingerprint sensor 161-1 with the authentication data stored in memory 120 and executes the application based on the comparison result. Display module 140 can display the information executed according to the application logic via display panel DP.
[0060] As another example, when a user selects the music stream icon displayed in display module 140, processor 110 obtains user input via input sensor 161-2 and activates the music stream application stored in memory 120. When a music playback command is input to the music stream application, processor 110 activates sound output module 163 and provides the user with sound information corresponding to the music playback command.

The gamma correction circuit 112-3 can convert the image data or gamma reference voltage so that the image displayed on the electronic device DD has the desired gamma characteristics. The rendering circuit 112-4 can receive image data from the controller 112-1 and can render the image data taking into account the pixel arrangement of the display panel DP applied to the electronic device DD. At least one of the data conversion circuit 112-2, the gamma correction circuit 112-3, and the rendering circuit 112-4 can be integrated into any other component (e.g., the main processor 111 or the controller 112-1). At least one of the data conversion circuit 112-2, the gamma correction circuit 112-3, and the rendering circuit 112-4 can be integrated into the data driver DDC, which will be described later.

Memory 120 may include at least one of volatile memory 121 and non-volatile memory 122.
[0068] The input module 130 can receive instructions or data from outside the electronic device DD (e.g., from a user or external electronic device 102) that will be used by components of the electronic device DD (e.g., processor 110, sensor module 161, or sound output module 163).

For example, the scan driver SDC may include an amorphous silicon TFT gate drive circuit (ASG), a low-temperature polycrystalline silicon (LTPS) TFT gate drive circuit, or an oxide semiconductor TFT gate drive circuit (OSG) integrated into the display panel DP. The scan driver SDC receives control signals from the controller 112-1 and outputs scan signals to the display panel DP in response to the control signals. According to embodiments of this disclosure, the area or width occupied by the scan driver SDC can be designed to be reduced. Therefore, an electronic device DD with a reduced bezel area width can be provided.

[0092] Communication module 173 can establish a wired or wireless communication channel between electronic device DD and external electronic device 102, and can support communication execution through the established communication channel. Communication module 173 may include one or all of the following: a wireless communication module (such as a cellular communication module, a short-range wireless communication module, or a Global Navigation Satellite System (GNSS) communication module) and a wired communication module (such as a local area network (LAN) communication module or a power line communication module). Communication module 173 can communicate with external electronic device 102 through short-range communication networks (such as Bluetooth, Wi-Fi Direct, or Infrared Data Association (IrDA)) or long-range communication networks (such as cellular networks, the Internet, or computer networks (e.g., LAN or WAN)). The various types of communication modules described above can be implemented using a single chip or separate chips.
[0093] The input module 130, sensor module 161, camera module 171, etc., can be used together with the processor 110 to control the operation of the display module 140.
[0094] Processor 110 outputs instructions or data to display module 140, sound output module 163, camera module 171, or optical module 172 based on input data received from input module 130. For example, processor 110 can generate image data corresponding to input data applied via a mouse or active pen, and can output the image data to display module 140. In an embodiment, processor 110 can generate instruction data corresponding to input data, and can output the instruction data to camera module 171 or optical module 172. When no input data is received from input module 130 during a given time period, processor 110 can switch the operating mode of electronic device DD to low-power mode or sleep mode, thereby reducing the power consumption of electronic device DD.

Processor 110 can execute instructions based on sensing data sensed by input sensor 161-2 or digitizer 161-3, or it can output image data corresponding to the sensing data to display module 140. When sensor module 161 includes a temperature sensor, processor 110 can receive temperature data associated with the measured temperature from sensor module 161, and can also perform brightness correction on image data based on the temperature data.
[0096] Processor 110 can receive measurement data from camera module 171 regarding the presence or absence of a user, the user's position, and the user's line of sight. Processor 110 can also perform brightness correction on image data based on the measurement data. For example, processor 110, which determines the presence or absence of a user based on input from camera module 171, can display image data whose brightness has been corrected by data conversion circuit 112-2 or gamma correction circuit 112-3.

[0109] The scan driver SDC can be formed directly on the substrate layer using photolithography. For example, the scan driver SDC can be formed together with the pixel driver circuit using the same process used to form the pixel PX.
[0110] The control circuit TC controls the operation of the scan driver SDC and the data driver DDC. The control circuit TC generates image data (RGB) by converting the data format of the input image signal to match the interface specification of the data driver DDC. The control circuit TC outputs the image data (RGB) and various control signals DCS and GCS. The control circuit TC can correspond to... Figure 1B The controller 112-1.
[0111] The scan driver SDC receives a first control signal GCS from the control circuit TC. The first control signal GCS may include a vertical start signal to initiate operation of the scan driver SDC, a clock signal to determine when to output a signal, etc. The scan driver SDC can output multiple scan signals to multiple scan lines SCL1 to SCLn and SSL1 to SSLn. "n" can be an integer greater than or equal to 2. The scan driver SDC may be referred to as a gate driver.
[0112] The data driver DDC receives the second control signal DCS and image data RGB from the control circuit TC. The data driver DDC converts the image data RGB into a data signal and outputs the data signal to multiple data lines DL1 to DLm. "m" can be an integer equal to or greater than 2. The data signal is an analog voltage corresponding to the grayscale value of the image data RGB. The data driver DDC can be configured as a driver chip and installed in... Figure 2 The connecting film COF shown can be mounted on the circuit board PCB, or on the non-display area NDA of the display panel DP.
[0113] The display panel DP may include multiple scan lines SCL1 to SCLn and SSL1 to SSLn, multiple data lines DL1 to DLm, multiple readout lines RL1 to RLm, and multiple pixels PX.

Scan lines SCL1 to SCLn and SSL1 to SSLn can include first-type scan lines SCL1 to SCLn and second-type scan lines SSL1 to SSLn. The first-type scan lines SCL1 to SCLn can be referred to as first scan lines, write scan lines, or first gate lines, and the second-type scan lines SSL1 to SSLn can be referred to as second scan lines, initialization scan lines, sensing scan lines, or second gate lines.
[0115] Data lines DL1 to DLm can be arranged along the second direction DR2, and each of data lines DL1 to DLm can extend along the first direction DR1. Readout lines RL1 to RLm can be arranged along the second direction DR2, and each of readout lines RL1 to RLm can extend along the first direction DR1.

A pixel PX arranged in the first column can be connected to the first data line DL1 and the first readout line RL1, and a pixel PX arranged in the mth column can be connected to the mth data line DLm and the mth readout line RLm. However, this is only an example, and the connection relationships between pixels PX and scan lines SCL1 to SCLn and SSL1 to SSLn, data lines DL1 to DLm, and readout lines RLm are not limited to this.
[0117] The display panel DP receives a first power voltage ELVDD and a second power voltage ELVSS. The first power voltage ELVDD can be supplied to the pixel PX. The display panel DP can also receive an initialization voltage Vint. The initialization voltage Vint can be supplied to the pixel PX.

[0119] exist Figure 4 The example illustrates multiple pixels PX (see [example]). Figure 3 The equivalent circuit diagram of one pixel PXij in the set of pixels PX. Since each of the multiple pixels PX has the same circuit structure, the description of the circuit structure of pixel PXij also applies to each of the remaining pixels PX. For pixel PXij, "i" can be an integer equal to or greater than 1 and equal to or less than "n", and "j" can be an integer equal to or greater than 1 and equal to or less than "m".

[0121] The pixel driving circuit PDC may include a first transistor TR1, a second transistor TR2, a third transistor TR3, and a capacitor Cst. The construction of the pixel driving circuit PDC according to this disclosure is not limited to... Figure 4 The embodiment shown. Figure 4 The pixel driver circuit PDC shown is merely an example, and its construction can be modified and implemented. For example, the pixel driver circuit PDC may also include at least one transistor and at least one capacitor.
[0122] In embodiments of this disclosure, each of the first transistor TR1, the second transistor TR2, and the third transistor TR3 is described as an N-type thin-film transistor. However, this disclosure is not limited thereto. For example, at least any one of the first transistor TR1, the second transistor TR2, and the third transistor TR3 may be a P-type thin-film transistor.
[0123] Furthermore, each of the first transistor TR1, the second transistor TR2, and the third transistor TR3 may be a transistor having an oxide semiconductor layer. However, this disclosure is not particularly limited thereto. For example, at least one of the first transistor TR1, the second transistor TR2, and the third transistor TR3 may be a transistor having a low-temperature polycrystalline silicon (LTPS) semiconductor layer.
[0124] The first transistor TR1 can be electrically connected between the first power line PL1 and the light-emitting element ED. The first transistor TR1 may include a gate electrode connected to the first node N1, a first electrode electrically connected to the first power line PL1, and a second electrode connected to the light-emitting element ED. The light-emitting element ED and the first transistor TR1 can be electrically connected to each other at the second node N2. The first power voltage ELVDD can be provided to the pixel PXij through the first power line PL1.
[0125] The first transistor TR1 can control the amount of current flowing to the light-emitting element ED in response to the voltage of the first node N1. For example, the first transistor TR1 can be turned on when the voltage between the first node N1 and the second node N2 (i.e., the gate-source voltage) is higher than the threshold voltage.
[0126] The second transistor TR2 can be electrically connected between the j-th data line DLj and the first node N1. The second transistor TR2 may include a gate electrode connected to the i-th first type scan line SCLi, a first electrode connected to the j-th data line DLj, and a second electrode connected to the first node N1.
[0127] The second transistor TR2 can transmit the data voltage DS received from the j-th data line DLj to the first node N1 in response to the i-th first-type scan signal SCi provided to the i-th first-type scan line SCLi. For example, the second transistor TR2 can be turned on when the i-th first-type scan signal SCi is at a logic high level.
[0128] A third transistor TR3 may be electrically connected between the second node N2 and the j-th readout line RLj. The third transistor TR3 may include a gate electrode connected to the i-th second-type scan line SSLi, a first electrode connected to the j-th readout line RLj, and a second electrode connected to the second node N2. The third transistor TR3 may connect the second node N2 and the j-th readout line RLj in response to an i-th second-type scan signal SSi provided to the i-th second-type scan line SSLi. For example, the third transistor TR3 may be turned on when the i-th second-type scan signal SSi has a logic high level.
[0129] According to embodiments of this disclosure, during image display operation, the third transistor TR3 can transmit the initialization voltage Vint to the second node N2 in response to the i-th second type scan signal SSi. That is, when the third transistor TR3 is turned on, the second electrode of the first transistor TR1 can be reset to the initialization voltage Vint.
[0130] During sensing operation, the third transistor TR3 can transmit a sensing current corresponding to the voltage of the second node N2 to the j-th readout line RLj in response to the i-th second-type scan signal SSi. Control circuit TC (see reference) Figure 3 It can receive the sensed current to determine the threshold voltage or mobility of the first transistor TR1 and generate compensated image data RGB.
[0131] A capacitor Cst can be connected between the first node N1 and the second node N2. When the data voltage DS is supplied, the initialization voltage Vint can be supplied to the second node N2. In this case, the differential voltage between the data voltage DS and the initialization voltage Vint can be stored in the capacitor Cst. The voltage stored in the capacitor Cst can be used to determine whether the first transistor TR1 is turned on or off.
[0132] A light-emitting element (ED) can be connected between a second node N2 and a second electric field line PL2. A second electric field voltage ELVSS can be applied to the second electric field line PL2. The ED can include a first electrode (e.g., an anode), a second electrode (e.g., a cathode), and a light-emitting layer between the first and second electrodes. For example, the first electrode can be connected to the second node N2, and the second electrode can be connected to the second electric field line PL2. The ED can generate light with a specific brightness corresponding to the amount of current supplied from the first transistor TR1.
[0133] Figure 5 This is a block diagram illustrating some components of a display panel DP according to an embodiment of the present disclosure.
[0134] Reference Figure 5 The image shows a portion of the scan driver SDC and pixels PX. The scan driver SDC may include a first type scan driver SCD and a second type scan driver SSD. The first type scan driver SCD includes multiple first type classes SC-ST1, SC-ST2, and SC-ST3, and the second type scan driver SSD may include multiple second type classes SS-ST1, SS-ST2, and SS-ST3.
[0135] According to embodiments of this disclosure, first type classes SC-ST1, SC-ST2, and SC-ST3 can be arranged along a first direction DR1, and second type classes SS-ST1, SS-ST2, and SS-ST3 can also be arranged along the first direction DR1. Furthermore, the first type classes SC-ST1, SC-ST2, and SC-ST3, as well as the second type classes SS-ST1, SS-ST2, and SS-ST3, can be arranged to be spaced apart from each other on a second direction DR2 that intersects the first direction DR1.
[0136] According to embodiments of this disclosure, the first type levels SC-ST1, SC-ST2, and SC-ST3 and the second type levels SS-ST1, SS-ST2, and SS-ST3 can be arranged to be spaced apart from each other in a direction intersecting the arrangement direction of the pixel row PX-r. In this case, the lines for transmitting signals to the first type levels SC-ST1, SC-ST2, and SC-ST3 and the lines for transmitting signals to the second type levels SS-ST1, SS-ST2, and SS-ST3 can be divided into left and right regions (i.e., the left and right regions in the figures) on the second direction DR2. Therefore, it is easier to use designs that reduce the length of the lines used in the scan driver SDC or reduce the width of the scan driver SDC on the second direction DR2.
[0137] According to embodiments of this disclosure, first type levels SC-ST1, SC-ST2, and SC-ST3 can be electrically connected to multiple first type scan lines SCLs, respectively. Furthermore, second type levels SS-ST1, SS-ST2, and SS-ST3 can be electrically connected to multiple second type scan lines SSLs, respectively. For example, a first type level SC-ST1 can be connected to “Y” first type scan lines SCLs to output “Y” first type scan signals, and a second type level SS-ST1 can be connected to “Y” second type scan lines SSLs to output “Y” second type scan signals. “Y” can be an integer of 2 or greater.
[0138] Also refer to Figure 4 At least one of the first type stages SC-ST1, SC-ST2, and SC-ST3 can output a first type scan signal SCi to the gate electrode of the second transistor TR2, and at least one of the second type stages SS-ST1, SS-ST2, and SS-ST3 can output a second type scan signal SSi to the gate electrode of the third transistor TR3. In another embodiment of the invention, the functions of the first type stages SC-ST1, SC-ST2, and SC-ST3 and the second type stages SS-ST1, SS-ST2, and SS-ST3 can be reversed. In this case, at least one of the first type stages can output a first type scan signal to the gate electrode of the third transistor TR3, and at least one of the second type stages can output a second type scan signal to the gate electrode of the second transistor TR2.
[0139] exist Figure 5 The illustration shows, by way of example, a first type level SC-ST1 electrically connected to six first type scan lines SCLs and a second type level SS-ST1 electrically connected to six second type scan lines SSLs, but this disclosure is not particularly limited thereto. For example, two or more first type scan lines SCLs may be connected to a first type level SC-ST1, and two or more second type scan lines SSLs may be connected to a second type level SS-ST1.
[0140] According to embodiments of this disclosure, a plurality of pixels PX can be arranged in a first direction DR1 and a second direction DR2. Among the plurality of pixels PX, pixels PX-r in a row arranged in the second direction DR2 (hereinafter referred to as a pixel row) can be connected to a first type level SC-ST1 and a second type level SS-ST1. Furthermore, the pixels PX include pixels PXG1 in a “Y” row arranged in the first direction DR1 (hereinafter referred to as a first pixel group), and the first pixel group PXG1 can be connected to a first type level SC-ST1 and a second type level SS-ST1.
[0141] The first pixel group PXG1, comprising six rows of PX-r, can be connected to the first first type level SC-ST1 and the first second type level SS-ST1. The second pixel group PXG2, comprising the next six rows of PX-r, can be connected to the second first type level SC-ST2 and the second second type level SS-ST2. The third pixel group PXG3, comprising the next six rows of PX-r, can be connected to the third first type level SC-ST3 and the third second type level SS-ST3.
[0142] According to embodiments of this disclosure, a level (e.g., a first type level SC-ST1) can control the operation of a pixel group (e.g., a first pixel group PXG1) comprising two or more pixel rows PX-r. That is, the total number of levels can be less than the number of rows of pixels PX. Therefore, the amount of space required in the non-display area NDA (see...) can be reduced. Figure 3 This reduces the number of transistors, capacitors, and lines (e.g., clock lines) in the display panel. As a result, the display panel's display output (DP) can be reduced (see...). Figure 2 The non-display area NDA (see) Figure 3 The width of ).

Furthermore, the gate electrodes of both the first transistor T81 and the second transistor T82 can be connected to the second node QB. The first transistor T81 and the second transistor T82 can transmit a first low voltage VSS1 to the third node N-CQ in response to the voltage at the second node QB. Therefore, the eighth circuit S108 can be referred to as the third node stabilization circuit.
[0181] The ninth circuit S109 may include multiple output circuits S109s. In embodiments of this disclosure, since one stage ST[N] outputs six scan signals, the ninth circuit S109 may include six output circuits S109s. Figure 6B The example shows a total of two output circuits: the first output circuit and the last output circuit (e.g., the sixth output circuit).
[0182] Each of the output circuits S109s may include a first transistor T91, a second transistor T92, a third transistor T93, and a capacitor C9. The first output circuit S109s is described below, and the remaining output circuits S109s also include substantially the same construction, therefore their repeated description is omitted.
[0183] The first transistor T91 can be connected between the first clock terminal CIN1 and the first output terminal OUT1. The gate electrode of the first transistor T91 can be connected to the partition node Q-1. The second transistor T92 can be connected between the first node QC and the partition node Q-1. The gate electrode of the second transistor T92 can be connected to the third node N-CQ. The second transistor T92 can connect the first node QC and the partition node Q-1 in response to the voltage of the third node N-CQ, or it can disconnect the first node QC and the partition node Q-1.
[0184] The operation of the first transistor T91 is controlled in response to the voltage of the partition node Q-1. When the first transistor T91 is turned on, the logic high level voltage of the first scan signal SS1[N] can be output to the first output terminal OUT1.
[0185] According to embodiments of this disclosure, transistor T71 can be turned on in a timing sequence when the fourth node NB is boosted to transfer the first high voltage VDD1 to the third node N-CQ. During the timing sequence of the fourth node NB being boosted, the voltage of the first node QC can be higher than the first high voltage VDD1 of the third node N-CQ. Therefore, the second transistor T92 can be turned off. The second transistor T92 can separate the first node QC and the partition node Q-1 in response to the voltage of the third node N-CQ.
[0186] When signals are output to the first output terminal OUT1, the second output terminal OUT2 (not shown), the third output terminal OUT3 (not shown), the fourth output terminal OUT4 (not shown), the fifth output terminal OUT5 (not shown), and the sixth output terminal OUT6, the first node QC and the dividing node Q-1 can be electrically isolated from each other, and the dividing nodes Q-1 to Q-6 can also be electrically isolated from each other. Therefore, even if the voltage of the dividing node Q-1 is coupled and changed according to the signal output to the first output terminal OUT1, the influence on other nodes can be eliminated. For example, other nodes can be the first node QC and any of the dividing nodes Q-1 to Q-6 other than the dividing node Q-1. Therefore, horizontal line defects caused by differences in brightness relative to the line can be eliminated.
[0187] According to an embodiment of this disclosure, when the second low voltage VSS2 is transmitted to the first node QC in response to the gate turn-on voltage of the third carry signal CR[N+1], the voltage of the first node QC can be lower than the voltage of the third node N-CQ. In this case, the second transistor T92 is turned on to connect to the first node QC, and the partition node Q-1 can be discharged.
[0188] The third transistor T93 can be connected between the first output terminal OUT1 and the fifth input terminal IN5. The gate electrode of the third transistor T93 can be connected to the second node QB. The operation of the third transistor T93 is controlled in response to the voltage of the second node QB. When the third transistor T93 is turned on, a first low voltage VSS1 can be provided to the first output terminal OUT1.
[0189] Capacitor C9 is connected to partition node Q-1 and fourth node NB. Capacitor C9 can increase (boost) the voltage of partition node Q-1 in response to an increase in the voltage of fourth node NB. When the voltage of partition node Q-1 increases, a first scan signal SS1[N] with a high voltage can be output without distortion. Figure 7 This is a timing diagram used to describe the operation of the level in the first mode MD1 according to an embodiment of the present disclosure. Figure 8 It is a timing diagram of a plurality of clock signals used to describe the operation of a level in a second mode MD2 according to an embodiment of the present disclosure.
[0190] Reference Figure 1A , Figure 7 and Figure 8 The display panel DP can selectively operate in either a first mode MD1 or a second mode MD2. For example, the first mode MD1 can be a normal driving mode driven at a first frequency, and the second mode MD2 can be a high-frequency driving mode driven at a second frequency higher than the first frequency. For example, the first frequency can be 240Hz, and the second frequency can be 480Hz. However, the first and second frequencies described above are merely examples, and are not particularly limited to the examples above.
[0191] Reference Figure 7 The example illustrates the first carry signal CR[N-1], the second carry signal CR[N], the third carry signal CR[N+1], the boost clock signal BCK, the carry clock signal CR_CK, and the first clock signal CK1, the second clock signal CK2, the third clock signal CK3, the fourth clock signal CK4, the fifth clock signal CK5, and the sixth clock signal CK6 under the first mode MD1.
[0192] Reference Figure 8 The example illustrates the first carry signal CR[N-1], the second carry signal CR[N], the third carry signal CR[N+1], the boost clock signal BCKa, the carry clock signal CR_CKa, and the first clock signal CK1a, the second clock signal CK2a, the third clock signal CK3a, the fourth clock signal CK4a, the fifth clock signal CK5a, and the sixth clock signal CK6a in the second mode MD2.
[0193] Reference Figure 7 and Figure 8 In the first mode MD1, the period CY1 of the boost clock signal BCK can be longer than the period CY1a of the boost clock signal BCKa in the second mode MD2. For example, the period CY1 can be twice the period CY1a. Furthermore, the period CY2 of the carry clock signal CR_CK in the first mode MD1 can be longer than the period CY2a of the carry clock signal CR_CKa in the second mode MD2. For example, the period CY2 can be twice the period CY2a. In other words, in the second mode MD2, the clock period can be reduced.
[0194] According to embodiments of this disclosure, at least some of multiple scan lines can be driven (e.g., activated) simultaneously for low-power or high-speed driving. For example, two scan lines can be driven simultaneously, and the second mode MD2 can be referred to as a dual-line gate drive mode. In embodiments of this disclosure, the first mode MD1 can be a high-resolution mode, and the second mode MD2 can be a high scan rate mode.
[0195] In the first mode MD1, the first clock signal CK1, the second clock signal CK2, the third clock signal CK3, the fourth clock signal CK4, the fifth clock signal CK5, and the sixth clock signal CK6 can have different phases. That is, the first clock signal CK1, the second clock signal CK2, the third clock signal CK3, the fourth clock signal CK4, the fifth clock signal CK5, and the sixth clock signal CK6 can have waveforms shifted by a specific interval. Correspondingly, the first scan signal SS1, the second scan signal SS2, the third scan signal SS3, the fourth clock signal CK4, the fifth clock signal CK5, and the sixth scan signal SS6, which are output synchronously with the first clock signal CK1, the second clock signal CK2, the third clock signal CK3, the fourth clock signal CK4, the fifth clock signal CK5, and the sixth scan signal SS6, can also have different phases. The first scan signal SS1, the second scan signal SS2, the third scan signal SS3, the fourth scan signal SS4, the fifth scan signal SS5, and the sixth scan signal SS6 can also be referred to as the first mode scan signal.
[0196] The first scan signal SS1, the second scan signal SS2, the third scan signal SS3, the fourth scan signal SS4, the fifth scan signal SS5, and the sixth scan signal SS6 can each pass through the first type of scan lines SCLs (see...). Figure 5 The first scan signal (or first type scan signal) provided by the system. In an embodiment, the first scan signal SS1, the second scan signal SS2, the third scan signal SS3, the fourth scan signal SS4, the fifth scan signal SS5, and the sixth scan signal SS6 may be provided by second type scan lines SSLs (see...). Figure 5 The second scan signal (or second type scan signal) provided.
[0197] In the second mode MD2, some of the clock signals CK1a, CK2a, CK3a, CK4a, CK5a, and CK6a can have the same phase. For example, the waveforms of the first clock signal CK1a and the second clock signal CK2a can be identical. The third clock signal CK3a can have a waveform shifted by a specific time relative to the first clock signal CK1a, and the waveforms of the third clock signal CK3a and the fourth clock signal CK4a can be identical. Furthermore, the waveforms of the fifth clock signal CK5a and the sixth clock signal CK6a can be identical.
[0198] In the second mode MD2, some of the first scan signals SS1a, second scan signals SS2a, third scan signals SS3a, fourth clock signals CK4a, fifth clock signals CK5a, and sixth scan signals SS6a, which are output synchronously with the first clock signal CK1a, second clock signal CK2a, third clock signal CK3a, fourth clock signal CK4a, fifth clock signal CK5a, and sixth clock signal CK6a, can have the same waveform. For example, the first scan signal SS1a and the second scan signal SS2a can be superimposed on each other and can have substantially the same waveform. In this case, in the second mode MD2, the data voltage DS (see...) Figure 4 It can simultaneously provide pixels in one row that receive the first scan signal SS1a and pixels in another row that receive the second scan signal SS2a.
[0199] The third scan signal SS3a and the fourth scan signal SS4a can be superimposed on each other and have substantially the same waveform. The fifth scan signal SS5a and the sixth scan signal SS6a can be superimposed on each other and have substantially the same waveform. The first scan signal SS1a, the second scan signal SS2a, the third scan signal SS3a, the fourth scan signal SS4a, the fifth scan signal SS5a, and the sixth scan signal SS6a can also be referred to as the second mode scan signal.
[0200] The first scan signal SS1a, the second scan signal SS2a, the third scan signal SS3a, the fourth scan signal SS4a, the fifth scan signal SS5a, and the sixth scan signal SS6a can be respectively passed through the first type of scan lines SCLs (see...). Figure 5The first scan signal (or first type scan signal) provided by the system. In an embodiment, the first scan signal SS1a, the second scan signal SS2a, the third scan signal SS3a, the fourth scan signal SS4a, the fifth scan signal SS5a, and the sixth scan signal SS6a may be provided by the second type scan lines SSLs (see [link to documentation]). Figure 5 The second scan signal (or second type scan signal) provided.
[0201] Figure 9 This is a view showing the activation state and brightness changes of a first type scan signal SC and a second type scan signal SS according to an embodiment of the present disclosure. Figure 10 This is a view illustrating the activation state and brightness changes of a first type scan signal SCa and a second type scan signal SSa according to embodiments of the present disclosure. The first type scan signal SC and the first type scan signal SCa may be provided to... Figure 4 The signal of the first type scan line SCLi shown in the figure, the second type scan signal SS and the second type scan signal SSa can be provided to Figure 4 The signal of the second type scan line SSLi shown in the figure.
[0202] Reference Figure 1A , Figure 9 and Figure 10 The display panel DP can operate in a mode driven by a variable frame rate (hereinafter referred to as Mode 3, MD3). For example, the variable frame rate can be modified in various ways from 1Hz to 240Hz, but is not particularly limited thereto. Figure 9 The brightness of the first type scan signal SC, the second type scan signal SS, and the display panel DP are shown as an example when driven at 240Hz. Figure 10 The brightness of the first type scan signal SCa, the second type scan signal SSa, and the display panel DP are shown as an example when driven at 60Hz.
[0203] Reference Figure 9 and Figure 10 When driving the display panel DP at 240Hz, during a unit time TU, the first type scan signal SC may include four write cycle portions WP, and the second type scan signal SS may include four initialization cycle portions IP. Furthermore, when driving the display panel DP at 60Hz, the first type scan signal SCa may include one write cycle portion WPa, and the second type scan signal SSa may include four initialization cycle portions IP.
[0204] In the write cycle portion WP or WPa, the first type scan signal SC or SCa may have a waveform that repeatedly transitions between logic high and logic low levels, and in the remaining portion excluding the write cycle portion WP or WPa, the first type scan signal SC or SCa may have a logic low level. Furthermore, in the initialization cycle portion IP, the second type scan signal SS or SSa may have a waveform that repeatedly transitions between logic high and logic low levels.
[0205] Refer to together Figure 5 The multiple first-type stages SC-ST1, SC-ST2, and SC-ST3 of the first-type scan driver SCD that generate the first-type scan signal SC or SCa, and the multiple second-type stages SS-ST1, SS-ST2, and SS-ST3 of the second-type scan driver SSD that generate the second-type scan signal SS or SSa, can be separated from each other. Therefore, the operation of the first-type scan signal SC or SCa and the operation of the second-type scan signal SS or SSa can be separated from each other. As a result, within a unit time TU, the number of initialization cycle portions IP can be adjusted independently, regardless of the number of write cycle portions WP or WPa, which varies according to the operating frequency of the display panel DP. In this case, the difference in optical waveforms according to the operating frequency of the display panel DP can be reduced, and consequently, the difference in brightness according to the operating frequency of the display panel DP can be reduced. That is, the image display quality of the display panel DP can be improved.
[0206] Figure 7 , Figure 8 , Figure 9 and Figure 10 The driving modes described herein can be applied to the display panel DP in various combinations. For example, in embodiments of this disclosure, the display panel DP can operate under any of the first mode MD1, the second mode MD2, and the third mode MD3. The first mode MD1 may correspond to a mode driven at 240Hz in the third mode MD3. In embodiments of this disclosure, the display panel DP can operate under either the first mode MD1 or the third mode MD3. In this case, the first mode MD1 may be a general driving mode driven at a fixed frequency, and the third mode MD3 may be a variable driving mode driven at a variable frequency. In other embodiments of this disclosure, the display panel DP can operate under either the first mode MD1 or the second mode MD2. In embodiments of this disclosure, the display panel DP may operate only under the first mode MD1. In other embodiments of this disclosure, the display panel DP may operate only under the third mode MD3.

Pixels PX1, PX2, PX3, PX4, PX5, and PX6 may include a first pixel PX1, a second pixel PX2, a third pixel PX3, a fourth pixel PX4, a fifth pixel PX5, and a sixth pixel PX6 arranged sequentially along the first direction DR1.
[0210] The first pixel PX1, the second pixel PX2, the third pixel PX3, the fourth pixel PX4, the fifth pixel PX5, and the sixth pixel PX6 can receive scan signals provided from a group-level GST. For example, a group-level GST may include a first type level SC-ST and a second type level SS-ST, and the first type level SC-ST can provide first type scan signals to first type scan lines SCL1 to SCL6, and the second type level SS-ST can provide second type scan signals to second type scan lines SSL1 to SSL6.

For example, the non-display area NDA may include a first non-display area NDA1, a second non-display area NDA2, a third non-display area NDA3, a fourth non-display area NDA4, a fifth non-display area NDA5, a sixth non-display area NDA6, and an introduction area INDA. The first non-display area NDA1, the second non-display area NDA2, the third non-display area NDA3, the fourth non-display area NDA4, the fifth non-display area NDA5, the sixth non-display area NDA6, and the introduction area INDA can be sequentially defined along the second direction DR2 in the direction facing the display area DA. That is, the first non-display area NDA1 can be closest to the edge of the display panel DP, and the introduction area INDA can be closest to the display area DA.
[0212] The second power line PL2 can be set in the first non-display area NDA1. The second power voltage ELVSS (see...) Figure 4 A second power line PL2 can be applied. The second power line PL2 can be electrically connected to pixel PXij (see...). Figure 4 ).
[0213] The first type clock line CKLT1 can be located in the second non-display area NDA2. Some of the first type clock lines CKLT1 can be the first clock signal CK1, the second clock signal CK2, the third clock signal CK3, the fourth clock signal CK4, the fifth clock signal CK5, and the sixth clock signal CK6 provided to the first type level SC-ST (see...). Figure 6A () line.
[0214] The first type of clock line CKLT1 may include a first clock line CLK1, a second clock line CLK2, a third clock line CLK3, a fourth clock line CLK4, a fifth clock line CLK5, and a sixth clock line CLK6. Each of the first clock lines CLK1, CLK2, CLK3, CLK4, CLK5, and CLK6 extends along a first direction DR1, and the first clock lines CLK1, CLK2, CLK3, CLK4, CLK5, and CLK6 may be arranged along a second direction DR2. The six clock lines in the first type of clock line CKLT1 arranged to the right of the sixth clock line CLK6 may be used to transmit clock signals to... Figure 11 The next set of levels of GST is shown as the first type level line.
[0215] The first type-level SC-ST can be located in the third non-display area NDA3. That is, since the first type-level SC-ST is set directly adjacent to the first type clock line CKLT1, the line design length in the circuit can be reduced or minimized. The first type-level SC-ST may include multiple first buffer circuits BC1 and first logic circuits LC1. The first buffer circuits BC1 can respectively correspond to... Figure 6B The six output circuits S109s shown are illustrated. The first logic circuit LC1 can correspond to... Figure 6B The diagram shows the remainder of a stage ST[N] excluding the six output circuits S109s. However, this is merely an example, and each of the first buffer circuits BC1 may include only the first transistor T91, and some of the components represented by the output circuits S109s may be omitted, or other components may be included in addition to those represented by the output circuits S109s.
[0216] According to an embodiment of this disclosure, a first buffer circuit BC1 can be disposed between the first logic circuit LC1 and the first type clock line CKLT1. This is because the first buffer circuit BC1 receives the first clock signal CK1, the second clock signal CK2, the third clock signal CK3, the fourth clock signal CK4, the fifth clock signal CK5, and the sixth clock signal CK6 (see...) from the first type clock line CKLT1. Figure 6A Therefore, the first type clock line CKLT1 can be set to be closest to the first buffer circuit BC1. Thus, the length of the multiple first clock connection lines CLS1 that connect the first type clock line CKLT1 to the first buffer circuit BC1 can be minimized.
[0217] According to embodiments of this disclosure, the first buffer circuit BC1 can be arranged sequentially along the first direction DR1. That is, the arrangement direction of the first buffer circuit BC1 can be the same as the arrangement direction of the first pixel PX1, the second pixel PX2, the third pixel PX3, the fourth pixel PX4, the fifth pixel PX5, and the sixth pixel PX6. In this case, the first buffer circuit BC1 and the first pixel PX1, the second pixel PX2, the third pixel PX3, the fourth pixel PX4, the fifth pixel PX5, and the sixth pixel PX6 can be arranged to face each other in the second direction DR2. Therefore, the length of the first type scan lines SCL1 to SCL6, which are connected to the first buffer circuit BC1 in a one-to-one correspondence and extend toward the first pixel to the sixth pixel PX1, PX2, PX3, PX4, PX5, and PX6, can be minimized.
[0218] The carry clock line CRCKL and the signal line SL can be located in the fourth non-display area NDA4. In embodiments of this disclosure, the signal line SL can be spaced apart from the display area DA, and the carry clock line CRCKL is located between the signal line SL and the display area DA. That is, the distance between the first type level SC-ST and the signal line SL can be less than the distance between the first type level SC-ST and the carry clock line CRCKL.
[0219] The second type-level SS-ST can be located in the fifth non-display area NDA5. The second type clock line CKLT2 can be located in the sixth non-display area NDA6. That is, since the second type-level SS-ST is set directly adjacent to the second type clock line CKLT2, the line design length in the circuit can be reduced or minimized. The second type-level SS-ST can include multiple second buffer circuits BC2 and second logic circuits LC2. The second buffer circuit BC2 can respectively correspond to... Figure 6B The six output circuits S109s shown are illustrated. The second logic circuit LC2 can correspond to... Figure 6BThe remaining portion of a stage ST[N] shown here, excluding the six output circuits S109s.
[0220] According to embodiments of this disclosure, a second buffer circuit BC2 can be disposed between the second logic circuit LC2 and the second type clock line CKLT2. The first type stage SC-ST and the second type stage SS-ST can have a structure that is linearly symmetrical to each other with respect to an imaginary line extending along the first direction DR1. The second buffer circuit BC2 can receive the first clock signal CK1, the second clock signal CK2, the third clock signal CK3, the fourth clock signal CK4, the fifth clock signal CK5, and the sixth clock signal CK6 from the second type clock line CKLT2, and can therefore be positioned closest to the second type clock line CKLT2. Therefore, the length of the multiple second clock connection lines CLS2 connecting the second type clock line CKLT2 to the second buffer circuit BC2 can be minimized.
[0221] According to embodiments of this disclosure, the second buffer circuit BC2 can be arranged sequentially along the first direction DR1. That is, the arrangement direction of the second buffer circuit BC2 can be the same as the arrangement direction of the first pixel PX1, second pixel PX2, third pixel PX3, fourth pixel PX4, fifth pixel PX5, and sixth pixel PX6. In this case, the second buffer circuit BC2 and the first pixel PX1, second pixel PX2, third pixel PX3, fourth pixel PX4, fifth pixel PX5, and sixth pixel PX6 can be aligned facing each other in the second direction DR2. Therefore, the length of the second type of scan lines SSL1 to SSL6, which are connected to the second buffer circuit BC2 in a one-to-one correspondence and extend toward the first pixel PX1, second pixel PX2, third pixel PX3, fourth pixel PX4, fifth pixel PX5, and sixth pixel PX6, can be minimized.
[0222] According to embodiments of this disclosure, a first clock connection line CLS1 can be routed around a first logic circuit LC1. A second clock connection line CLS2 and second type scan lines SSL1 to SSL6 can be routed around a second logic circuit LC2. That is, there is no space occupied by the first clock connection line CLS1 in the area where the first logic circuit LC1 is located, and there is no space occupied by the second clock connection line CLS2 and the second type scan lines SSL1 to SSL6 in the area where the second logic circuit LC2 is located. Therefore, the space available for designing the first logic circuit LC1 and the second logic circuit LC2 can be further ensured. Therefore, designs that narrow the width of the first logic circuit LC1 and the second logic circuit LC2 in the second direction DR2 are easier to implement.
[0223] According to embodiments of this disclosure, first type scan lines SCL1 to SCL6 can extend from the first buffer circuit BC1 to be electrically connected across the introduction region INDA to the first pixel PX1, the second pixel PX2, the third pixel PX3, the fourth pixel PX4, the fifth pixel PX5, and the sixth pixel PX6, respectively. Second type scan lines SSL1 to SSL6 can extend from the second buffer circuit BC2 and can be electrically connected across the introduction region INDA to the first pixel PX1, the second pixel PX2, the third pixel PX3, the fourth pixel PX4, the fifth pixel PX5, and the sixth pixel PX6, respectively. The introduction region INDA is the region adjacent to the first pixel PX1, the second pixel PX2, the third pixel PX3, the fourth pixel PX4, the fifth pixel PX5, and the sixth pixel PX6, and can be defined between the sixth non-display region NDA6 and the display region DA.
[0224] According to embodiments of this disclosure, first type scan lines SCL1 to SCL6 can extend from the first buffer circuit BC1 to positions connected to the first pixel PX1, the second pixel PX2, the third pixel PX3, the fourth pixel PX4, the fifth pixel PX5, and the sixth pixel PX6, respectively. Second type scan lines SSL1 to SSL6 can extend from the second buffer circuit BC2 to positions connected to the first pixel PX1, the second pixel PX2, the third pixel PX3, the fourth pixel PX4, the fifth pixel PX5, and the sixth pixel PX6, respectively. For example, the first first type scan line SCL1 can extend from the first buffer circuit BC1 to a position connected to the first pixel PX1, the second first type scan line SCL2 can extend from the first buffer circuit BC1 to a position connected to the second pixel PX2, and so on. Similarly, for example, the first second type scan line SSL1 can extend from the second buffer circuit BC2 to a position connected to the first pixel PX1, the second second type scan line SSL2 can extend from the second buffer circuit BC2 to a position connected to the second pixel PX2, and so on. Therefore, the fan-out portion used to align the first type scan lines SCL1 to SCL6 and the second type scan lines SSL1 to SSL6 according to the arrangement of the first pixel PX1, the second pixel PX2, the third pixel PX3, the fourth pixel PX4, the fifth pixel PX5, and the sixth pixel PX6 can be omitted. For example, the fan-out portion can refer to the portion in which a line extending along the first direction DR1 is provided. Therefore, the width of the non-display area NDA can be further reduced.
[0225] According to embodiments of this disclosure, the carry clock line CRCKL and the signal line SL can be disposed between the first type level SC-ST and the second type level SS-ST. At least some of the carry clock line CRCKL and the signal line SL can be electrically connected to both the first type level SC-ST and the second type level SS-ST. Figure 11The diagram shows a first connection line CLS41 and a second connection line CLS42 connected to one of the signal lines SL, and a first carry connection line CLS31 and a second carry connection line CLS32 connected to one of the carry clock lines CRCKL.
[0226] The first connecting line CLS41 can be electrically connected to a signal line SL and a first type level SC-ST, and can extend along the second direction DR2. The second connecting line CLS42 can be electrically connected to a signal line SL and a second type level SS-ST, and can extend along the second direction DR2. The first connecting line CLS41 and the second connecting line CLS42 can be spaced apart from each other in the second direction DR2.
[0227] The first carry connection line CLS31 can be electrically connected to a carry clock line CRCKL and a first type level SC-ST, and can extend along the second direction DR2. The second carry connection line CLS32 can be electrically connected to a carry clock line CRCKL and a second type level SS-ST, and can extend along the second direction DR2. The first carry connection line CLS31 and the second carry connection line CLS32 can be spaced apart from each other in the second direction DR2.
[0228] According to embodiments of this disclosure, since the carry clock line CRCKL and signal line SL are located between the first type level SC-ST and the second type level SS-ST, some of the connecting lines can be arranged to face each other in the second direction DR2. Therefore, the number of connecting lines arranged in the first direction DR1 can be reduced. Thus, design freedom is provided to reduce the width of lines extending in the first direction DR1 in the second direction DR2. Referring later... Figure 12A and Figure 12B Describe it in detail.
[0229] Furthermore, according to embodiments of this disclosure, the first type clock line CKLT1, the second type clock line CKLT2, the carry clock line CRCKL, and the signal line SL are arranged discontinuously. That is, the first type level SC-ST can be arranged between some of the first type clock lines CKLT1, CKLT2, CRCKL, and SL, and the second type level SS-ST can be arranged between some of the first type clock lines CKLT1, CKLT2, CRCKL, and SL, and the remainder. This reduces the number of crossing signal lines extending in the second direction DR2 that intersect a signal line extending in the first direction DR1. Therefore, design freedom is provided that can reduce the width of the line extending in the first direction DR1 in the second direction DR2, as will be discussed later. Figure 12A and Figure 12B Describe it in detail.
[0230] Figure 12A This is a plan view showing a single signal line SLL and multiple cross signal lines CLL according to a comparative example of this disclosure. Figure 12B This is a plan view showing a signal line SLLa and multiple cross signal lines CLLa according to an embodiment of the present disclosure.
[0231] Reference Figure 12A The diagram shows one signal line SLL and sixteen cross signal lines CLL. The signal line SLL can extend along a first direction DR1, and the cross signal lines CLL can overlap with the signal line SLL and can extend along a second direction DR2.
[0232] A signal line SLL may include a first layer line LL1 and multiple second layer patterns LL2 electrically connected to the first layer line LL1. The second layer patterns LL2 may be electrically connected to the first layer line LL1 via contact LCT. The second layer patterns LL2 may be disposed on the same layer as the crossover signal line CLL and may be electrically insulated from the crossover signal line CLL.
[0233] Multiple open LOPs and multiple slit LSLs can be defined within a single signal line SLL. Open LOPs can be provided to prevent coupling between the signal line SLL and the crossover signal line CLL. For example, an open LOP can be superimposed on a crossover signal line CLL. The portion where an open LOP is applied may act as a bottleneck and cause an increase in the resistance of a single signal line SLL. Therefore, as the number of open LOPs increases, the width of a single signal line SLL in the second direction DR2 may be increased to reduce resistance.
[0234] The slit LSL can be set in an area that does not overlap with the crossover signal line CLL. Figure 12A The diagram illustrates, as an example, two slit LSLs arranged on the second direction DR2. The slit LSLs can be configured to be placed in the manufacturing process of the display panel DP (see [reference]). Figure 1A In the process of curing the sealing member used in the manufacturing process, light is transmitted. Therefore, the slit LSL can be omitted from the signal line SLL included in the display panel DP, which has a structure that does not require a sealing member. Furthermore, the slit LSL can be omitted when the location of a signal line SLL is in an area that does not overlap with the sealing member.
[0235] Reference Figure 12B The diagram illustrates one signal line SLLa and six cross signal lines CLLa. The signal line SLLa can extend along a first direction DR1, and the cross signal lines CLLa can overlap with the signal line SLLa and extend along a second direction DR2. One signal line SLLa can be as shown above. Figure 11The description refers to any one of the following: Type 1 clock line CKLT1, Type 2 clock line CKLT2, carry clock line CRCKL, and signal line SL. The crossover signal line CLLa can be any of the lines described above. Figure 11 The first type of scan lines SCL1 to SCL6, the second type of scan lines SSL1 to SSL6, and at least some of the connecting lines CLS1, CLS2, CLS31, CLS32, CLS41, and CLS42 are described.
[0236] A signal line SLLa may include a first layer line LL1a and multiple second layer patterns LL2a electrically connected to the first layer line LL1a. The second layer patterns LL2a may be electrically connected to the first layer line LL1a via contact LTa. The second layer patterns LL2a may be disposed on the same layer as the cross signal line CLLa and may be electrically insulated from the cross signal line CLLa.
[0237] When the number of crossover signal lines CLLa stacked with signal line SLLa decreases, the number of openings LOPa set to prevent coupling can be reduced. In other words, as the number of bottleneck sections decreases, the width of a single signal line SLLa can be further reduced. For example, assuming the target resistance of signal lines SLLa is the same, Figure 12B The width SWT2 of the signal line SLLa superimposed with a relatively small number of cross signal lines CLLa in the second direction DR2 can be less than Figure 12A The width of the signal line SLL in the second direction DR2 is SWT1.
[0238] Figure 12C This is a plan view showing the signal line SLLb according to an embodiment of the present disclosure.
[0239] Reference Figure 12C A signal line SLLb may include a first layer line LL1b and a plurality of second layer patterns LL2b electrically connected to the first layer line LL1b. The second layer patterns LL2b may be electrically connected to the first layer line LL1b via contact LCTb.
[0240] Figure 12C The signal line SLLb shown can be set to be more than Figure 12B The signal line SLLa shown is close to the display area DA (see...) Figure 11 The signal line SLLb. For example, when Figure 12B The signal line SLLa shown is the first type clock line CKLT1 (see...) Figure 11 When one of the following is mentioned, Figure 12C The signal line SLLb shown can be the carry clock line CRCKL (see...) Figure 11One of them. The opening LOPb can be set in the signal line SLLb between the second layer patterns LL2b that are adjacent to each other on the first direction DR1.
[0241] In other words, because Figure 12C The signal line SLLb shown is configured to be spaced apart from the edge of the display panel DP, so the slit LSLa can be omitted (see...). Figure 12B In other words, the slit can be omitted from the signal line SLLb. Therefore, the resistance of the signal line SLLb can be further reduced, and the width SWT3 of the signal line SLLb in the second direction DR2 can be designed to be narrower.
[0242] Figure 13 This is a plan view showing some of the signal lines SL according to an embodiment of the present disclosure.
[0243] Reference Figure 13 The signal line SL is positioned between the first type level SC-ST and the second type level SS-ST. Therefore, within the signal line SL, the signal line SL-1, which is electrically connected to both the first type level SC-ST and the second type level SS-ST, can be connected to two connecting lines CLS41 and CLS42.
[0244] The two connecting lines CLS41 and CLS42 face each other in the second direction DR2 and can extend in opposite directions. Therefore, the number of connecting lines arranged in the first direction DR1 can be reduced. This provides design freedom by allowing for a reduction in the width of lines extending in the first direction DR1 in the second direction DR2. Furthermore, areas where no connecting lines are provided can be ensured as areas where other patterns or lines will be placed. In other words, design freedom can be further improved by ensuring the designable area.
[0245] Figure 14 This is a plan view of a portion of a display panel DPa according to an embodiment of the present disclosure. Figure 14 In the description, refer to Figure 11 The same reference numerals described are assigned to the same components, so their descriptions are omitted to avoid redundancy.
[0246] Above Figure 11 In this configuration, the voltage line SL-D can be placed together with the signal line SL in the fourth non-display area NDA4. That is to say, in... Figure 11 In this configuration, voltage line SL-D can be positioned between type 1 level SC-ST and type 2 level SS-ST. (Refer to...) Figure 14 At least some of the signal lines SL-Da among the signal lines SLa can be set in the sixth non-display area NDA6. Figure 14An example is shown where one of the signal lines SL-Da is located in the sixth non-display area NDA6. Hereinafter, a signal line SL-Da will be referred to as voltage line SL-Da.
[0247] The voltage line SL-Da can extend along the first direction DR1 and can be positioned between the second type clock line CKLT2 and the first pixel PX1, the second pixel PX2, the third pixel PX3, the fourth pixel PX4, the fifth pixel PX5, and the sixth pixel PX6. The voltage line SL-Da can have a specific voltage, for example, a constant voltage (or DC voltage). Therefore, the voltage line SL-Da can be used as a shielding line.
[0248] Due to the capacitance between the second type clock line CKLT2 and the circuit elements disposed in the display area DA, coupling between the second type clock line CKLT2 and the circuit elements may occur. According to embodiments of this disclosure, the voltage line SL-Da can receive... Figure 6B The second low voltage VSS2 is shown. That is, the voltage line SL-Da can be positioned between the second type clock line CKLT2 and the display area DA to act as a shielding layer. In other words, the voltage line SL-Da can prevent coupling between the second type clock line CKLT2 and circuit elements.
[0249] although Figure 14 As an example, a voltage line SL-Da is shown positioned between the second type clock line CKLT2 and the display area DA, but this disclosure is not particularly limited thereto. For example, at least some of the voltage lines SLa that are supplied with a specific voltage may be additionally positioned between the second type clock line CKLT2 and the display area DA.
[0250] Figure 15 This is a plan view of a portion of a display panel DPb according to an embodiment of the present disclosure. Figure 15 In the description, refer to Figure 14 The same reference numerals described are assigned to the same components, so their descriptions are omitted to avoid redundancy.
[0251] Reference Figure 15 The positions of the signal line SLb and the carry clock line CRCKLa, set in the fourth non-display area NDA4, can be related to... Figure 14 The positions of the signal line SL1 and the carry clock line CRCKL differ. For example, the carry clock line CRCKLa can be positioned between the first type level SC-ST and the signal line SL1, and the signal line SL1 can be positioned between the carry clock line CRCKLa and the second type level SS-ST.
[0252] In embodiments of this disclosure, at least some of the carry clock lines CRCKLa may also be positioned between a portion of signal line SLb and another portion of signal line SLb. That is, the arrangement order or arrangement of signal line SLb and carry clock line CRCKLa in the fourth non-display area NDA4 can be changed in various ways.
[0253] Figure 16 This is a plan view of a portion of a display panel DPc according to an embodiment of the present disclosure. Figure 16 In the description, refer to Figure 14 The same reference numerals described are assigned to the same components, so their descriptions are omitted to avoid redundancy.
[0254] Reference Figure 16 The second type clock line CKLT2 can be set in the second non-display area NDA2, and the second type level SS-ST can be set in the third non-display area NDA3. The carry clock line CRCKL and the signal line SLa can be set in the fourth non-display area NDA4. The first type level SC-ST can be set in the fifth non-display area NDA5. The first type clock line CKLT1 can be set in the sixth non-display area NDA6.
[0255] Figure 17 This is a plan view of a portion of a display panel DPd according to an embodiment of the present disclosure. Figure 17 In the description, refer to Figure 11 The same reference numerals described are assigned to the same components, so their descriptions are omitted to avoid redundancy.
[0256] Reference Figure 17 The first pixel PX1, the second pixel PX2, the third pixel PX3, the fourth pixel PX4, the fifth pixel PX5, and the sixth pixel PX6 can receive a scan signal provided from a group level GSTA. A group level GSTA may include an integrated logic circuit LC-C that controls the operation of the first buffer circuit BC1 and the second buffer circuit BC2.
[0257] In embodiments of this disclosure, the integrated logic circuit LC-C can be disposed between the signal line SL and the carry clock line CRCKL. The first buffer circuit BC1 can be disposed between the first type clock line CKLT1 and the integrated logic circuit LC-C, and the second buffer circuit BC2 can be disposed between the integrated logic circuit LC-C and the second type clock line CKLT2.
[0258] The non-display area NDA can be divided into multiple regions. For example, the non-display area NDA may include a first non-display area NDA1, a second non-display area NDA2, a third non-display area NDA3a, a fourth non-display area NDA4a, a fifth non-display area NDA5a, a sixth non-display area NDA6a, a seventh non-display area NDA7, an eighth non-display area NDA8, and an introduction area INDA. The first non-display area NDA1, the second non-display area NDA2, the third non-display area NDA3a, the fourth non-display area NDA4a, the fifth non-display area NDA5a, the sixth non-display area NDA6a, the seventh non-display area NDA7, the eighth non-display area NDA8, and the introduction area INDA can be sequentially defined along the second direction DR2 in the direction facing the display area DA.
[0259] In embodiments of this disclosure, the integrated logic circuit LC-C may correspond to the remainder of a stage ST[N] excluding the six output circuits S109s. Figure 6B A stage ST[N] shown may also include six output circuits with a connection relationship similar to that of the six output circuits S109s. In this case, the first buffer circuit BC1 and the second buffer circuit BC2 may each correspond to twelve output circuits.
[0260] The second power line PL2 can be located in the first non-display area NDA1, the first type clock line CKLT1 can be located in the second non-display area NDA2, the first buffer circuit BC1 can be located in the third non-display area NDA3a, the signal line SL can be located in the fourth non-display area NDA4a, the integrated logic circuit LC-C can be located in the fifth non-display area NDA5a, the carry clock line CRCKL can be located in the sixth non-display area NDA6a, the second buffer circuit BC2 can be located in the seventh non-display area NDA7, and the second type clock line CKLT2 and voltage line SL-Da can be located in the eighth non-display area NDA8. The carry connection line CLS3 can be electrically connected to a carry clock line CRCKL and an integrated logic circuit LC-C, and can extend along the second direction DR2. The connection line CLS4 can be electrically connected to a signal line SL and an integrated logic circuit LC-C, and can extend along the second direction DR2.
[0261] According to the above embodiment, the first buffer circuit BC1, the second buffer circuit BC2, and pixels PX1, PX2, PX3, PX4, PX5, and PX6 can be arranged on the first direction DR1, and the first buffer circuit BC1, the second buffer circuit BC2, and pixels PX1, PX2, PX3, PX4, PX5, and PX6 can be aligned on the second direction DR2, which intersects the first direction DR1. In this case, the fan-out portions used to align the first type scan lines SCL1 to SCL6 connected to the first buffer circuit BC1 and the second type scan lines SSL1 to SSL6 connected to the second buffer circuit BC2 according to the arrangement order of pixels PX1, PX2, PX3, PX4, PX5, and PX6 can be omitted or reduced. As a result, the display panel DP (see...) can be reduced. Figure 2 The non-display area NDA (see) Figure 3 The width of ).
[0262] Furthermore, the first type clock line CKLT1 can be configured to be adjacent to the first buffer circuit BC1, and the second type clock line CKLT2 can be configured to be adjacent to the second buffer circuit BC2. Therefore, the design length of lines (e.g., the first clock connection line CLS1 and the second clock connection line CLS2) in the non-display area NDA can be reduced or minimized. Additionally, since the signal line SL and the carry clock line CRCKL are located between the first buffer circuit BC1 and the second buffer circuit BC2, the number of crossover signal lines CLLa that cross a signal line SLLa can be reduced (see...). Figure 12B The number of (SLLa) signals can be reduced. In this case, as the number of bottleneck portions designed to prevent the combination of cross signal lines CLLa with a single signal line SLLa is reduced, the width of a single signal line SLLa can be further reduced. Therefore, the display panel DP (see [link to relevant documentation]) can be reduced. Figure 2 The non-display area NDA (see) Figure 3 The width of ).
[0263] As described above, the display panel includes multiple levels disposed in a non-display area, and each level may include a first buffer circuit for outputting a first type of scan signal to multiple pixels and a second buffer circuit for outputting a second type of scan signal to multiple pixels. Each of the first buffer circuit, the second buffer circuit, and the pixels may be arranged in a first direction, and the first buffer circuit, the second buffer circuit, and the multiple pixels may be aligned in a second direction intersecting the first direction. In this case, the fan-out portions used for aligning the first type of scan lines connected to the first buffer circuit and the second type of scan lines connected to the second buffer circuit according to the pixel arrangement order may be omitted or reduced.
[0264] Furthermore, the first type of clock line can be configured to be adjacent to the first buffer circuit, and the second type of clock line can be configured to be adjacent to the second buffer circuit. Therefore, the line design length in the non-display area can be reduced or minimized. Additionally, the number of crossover signal lines intersecting with a signal line can be reduced. When the number of crossover signal lines overlapping with a signal line is reduced, the width of a signal line can be further reduced because the number of bottleneck portions designed to prevent the crossover signal lines from combining with a signal line can be reduced. Therefore, the width of the non-display area can be reduced.
[0265] Although embodiments of this disclosure have been described for illustrative purposes, those skilled in the art will understand that various modifications and substitutions can be made without departing from the scope and spirit of this disclosure as disclosed in the appended claims.
