[0039] Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings, wherein like reference numerals always refer to like elements. In this regard, the present embodiments may have different forms and should not be construed as limited to the descriptions set forth herein. Accordingly, the embodiments are described below only by referring to the drawings to explain aspects of the present specification. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items. Throughout the disclosure, the expression "at least one of a, b, and c" means only a, only b, only c, both a and b, both a and c, both b and c, all of a, b, and c, or variations thereof.

[0040] It will be understood that when an element such as a layer, film, region, or plate is referred to as being "on" another element, it can be "directly" on the other element, or intervening elements may be present therebetween. It will also be understood that when an element such as a layer, film, region, or plate is referred to as being "under" another element, it can be "directly" under the other element, or intervening elements may be present therebetween.

[0041] In addition, for ease of illustration, the dimensions of the elements in the drawings may be exaggerated or reduced. For example, since the dimensions and thicknesses of the elements in the drawings are arbitrarily shown for ease of description, the following embodiments are not limited thereto. That is, for ease of description, the dimensions, thicknesses, and ratios of the elements shown in the drawings may be exaggerated and / or simplified for clarity. Accordingly, spatial relative terms such as "below", "beneath", "under", "underneath", "above", and "on" may be used herein to easily describe the relationship of one element or feature to another (other) element or feature.

[0042] The terms used herein to describe space, orientation, etc. are terms for describing the space and orientation shown in the drawings, but it is understood that they are terms for describing various other orientations or perspectives. For example, in the case where a device or element shown in the drawings is flipped, a device or element described as "below" can be interpreted as being oriented in other ways (e.g., rotated 90 degrees or in the opposite direction). For example, in the case where a device or element shown in the drawings is flipped, a device or element described as "above" can be interpreted as being oriented in other ways (e.g., rotated 90 degrees or in the opposite direction). Thus, the terms "below" and "above" can include both the upper and lower orientations. In addition, a device or element can be oriented differently from the drawings, and the description of the space or orientation set forth herein can be interpreted in various ways.

[0043] The terms "first", "second", "third", etc. may be used herein to describe specific elements herein, and such terms as "first", "second", and "third" may be used to distinguish one element from another element.

[0044] It will be understood that when an element is referred to as being "connected to" or "coupled to" another element, it can be directly or indirectly connected to or coupled to the other element. In the same manner, when an element is referred to as being "electrically connected to" another element, they can be directly connected and electrically connected to each other, or they can be indirectly connected and electrically connected to each other through a conductive element.

[0045] It will also be understood that when an element is referred to as being "between" two elements, it can be the only element between the two elements, or another element other than this element can be between the two elements.

[0046] The terms used herein are for the purpose of describing particular embodiments and are not intended to limit the disclosure. As used herein, the singular forms "a" and "an" are intended to also include the plural forms unless the context clearly indicates otherwise.

[0047] For example, the terms "comprising", "including", "having", etc. specify the presence of the stated features, integers, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0048] For example, in this specification, when a layer is referred to as having the "same layer structure" as another layer, the multiple layers included in that layer can be included in the other layer in the same order. For example, the multiple layers included in that layer and the multiple layers included in the other layer can respectively include the same materials and can be formed in the same order.

[0049] An electronic or electrical device and / or any other related device or component (e.g., some of the various modules) according to an embodiment of the present disclosure described herein can be implemented using any suitable hardware, firmware (e.g., application specific integrated circuit), software, or a combination of software, firmware, and hardware. For example, the various components of these devices can be formed on one integrated circuit (IC) chip or on separate IC chips. Additionally, the various components of these devices can be formed on a flexible printed circuit film, tape carrier package (TCP), printed circuit board (PCB), or a substrate. Further, the various components of these devices can be processes or threads running on one or more processors in one or more computing devices, executing computer program instructions and interacting with other system components for performing the various functions described herein.

[0050] The computer program instructions are stored in a memory, which can be implemented in a computing device using a standard memory device such as, for example, random access memory (RAM). The computer program instructions can also be stored in other non-transitory computer-readable media such as, for example, a CD-ROM, flash drive, etc. Additionally, those of ordinary skill in the art should recognize that, without departing from the spirit and scope of the exemplary embodiments of the present disclosure, the functions of various computing devices can be combined or integrated into a single computing device, or the functions of a particular computing device can be distributed over one or more other computing devices.

[0051] Hereinafter, a display device and a vehicle including a display panel according to an embodiment will be described in more detail based on the above description.

[0052] Figure 1 is a schematic conceptual diagram of a vehicle 1 including a display panel according to an embodiment. Figure 2 schematically shows Figure 1 an example of the interior of the vehicle 1.

[0053] As Figure 1 and Figure 2 shown, a vehicle 1 including a display panel (hereinafter referred to as vehicle 1) can include a display panel 10 and a control unit (or controller) 20.

[0054] The display panel 10 can be any one of various panels such as a liquid crystal display (LCD) panel or an organic light emitting diode (OLED) panel. The display panel 10 can include a display area DA for displaying an image (e.g., see Figure 6 ) and a peripheral area PA disposed around the display area DA (e.g., see Figure 6 ). The display panel 10 can include a user input sensor 11 (e.g., a touch sensor device, a touch panel, etc.).

[0055] For example, the user input sensor 11 can recognize a touch input of a user touching the display screen. The user input sensor 11 can be included in the display panel 10 as a touch panel (on-cell type), or can be included in the display panel 10 as an in-cell type.

[0056] The user input sensor 11 can include a plurality of touch sensors 11a and a driving driver 11b. The plurality of touch sensors 11a can include a plurality of touch electrodes. The plurality of touch electrodes can include, for example, a first touch conductive layer MTL1 and a second touch conductive layer MTL2 of the touch sensing layer YTL as described in the reference Figure 8 described.

[0057] The driving driver 11b can generate a driving signal of a predetermined standard and transmit the generated driving signal to the plurality of touch sensors 11a or the plurality of touch electrodes. For example, the driving signal can be the signal shown in the following description Figure 3 . The driving driver 11b can be arranged in the peripheral area PA of the substrate 100 described in the following reference Figure 6 described, and the plurality of touch sensors 11a or the plurality of touch electrodes can be arranged in the display area DA of the substrate 100 (e.g., see Figure 8 ) described below. In addition, as described in the following reference Figure 8 , it is assumed that the display panel 10 described herein is an OLED panel and the user input sensor 11 is of the on-cell type, but one or more embodiments are not limited thereto.

[0058] The control unit (or controller) 20 can be an electronic control unit for controlling the components of the vehicle 1. The control unit 20 can sense the vehicle state through the sensor 30 described below and can control the components (especially the display panel 10) included in the vehicle 1 based on the vehicle state. For example, the user input sensor 11 can include a driving driver 11b configured to generate a driving signal for touch input recognition. The control unit 20 can change the driving signal for touch input recognition by controlling the driving driver 11b according to one or more predetermined settings.

[0059] In addition, the control unit 20 can sense the vehicle state through the sensor 30 described below, and when the vehicle 1 meets the ISG entry condition, the control unit 20 can change the vehicle state to an idle stop and go (ISG) entry state. The ISG function described herein can refer to the function of shutting down the engine of the vehicle 1 when the vehicle 1 stops after meeting specific conditions while driving and restarting the engine when the vehicle 1 starts.

[0060] As described above, when the control unit 20 is an electronic control unit for controlling components of the vehicle 1, the control unit 20 can control the above-described drive driver 11b or user input sensor 11, and can accordingly further reduce the power consumption in the ISG mode.

[0061] For example, the control unit 20 may include a memory 21, a processor 22, and a communication module 23.

[0062] The processor 22 may be configured to execute instructions stored in the memory 21 to control other components. The processor 22 may be configured to execute instructions stored in the memory 21. The processor 22 is an element capable of performing operations and controlling another device. The processor 22 may mainly be a central processing unit (CPU), an application processor (AP), a graphics processing unit (GPU), etc., or include a central processing unit (CPU), an application processor (AP), a graphics processing unit (GPU), etc. In addition, the CPU, AP, or GPU may be included in a vehicle electronic control unit (ECU). The CPU, AP, or GPU may include one or more cores and may operate using a working voltage and a clock signal.

[0063] In addition to instructions, the memory 21 also stores data for supporting various functions of the control unit 20. The memory 21 may store one or more application programs or applications running on the control unit 20 and data and instructions for the operation of the control unit 20. The memory 21 may include at least one type of storage medium from a flash type, a hard disk type, a solid state drive (SSD) type, a silicon disk drive (SDD) type, a multimedia card micro type, a card type memory (e.g., a secure digital (SD) memory, an extreme digital (XD) memory, etc.), a RAM, a static random access memory (SRAM), a read only memory (ROM), an electrically erasable programmable read only memory (EEPROM), a programmable read only memory (PROM), a magnetic memory, a magnetic disk, and an optical disk.

[0064] The communication module 23 may be used as an interface capable of transmitting and receiving data with other components of the vehicle 1. The communication module 23 may use a safety standard due to vibrations and external impacts occurring when the vehicle 1 is in motion. In some cases, the communication module 23 may perform wired communication or wireless communication.

[0065] The vehicle 1 according to an embodiment may further include a sensor 30. The sensor 30 may obtain specific data through sensors arranged inside the vehicle 1. For example, the sensor 30 may include an engine sensor 31, a speed sensor 32, a battery state sensor 33, and a door open / close sensor 34.

[0066] The engine sensor 31 can sense whether the engine is on or off, the temperature of the engine, the revolutions per minute (RPM) of the engine, etc. The speed sensor 32 can sense the speed and / or acceleration of the vehicle 1. The battery status sensor 33 can sense the charge status of the battery, the battery temperature, the battery cycle, the battery voltage, etc. The door open / close sensor 34 can sense the open / close status of each door of the vehicle 1. In addition, the vehicle 1 may include a gear status sensor, a vehicle interior temperature sensor, a steering wheel position sensor, and a brake pressure sensor.

[0067] The vehicle 1 according to an embodiment may further include a vehicle battery 40, a vehicle actuator 50, a drive operation unit 60, and a vehicle starter 70. The vehicle battery 40 can provide power to drive all the electric drive electronic devices in the vehicle 1. For example, the vehicle battery 40 can provide power for driving the sensors 30, the display panel 10, etc. For example, in the case of an electric vehicle, the vehicle battery 40 can provide power for driving the motor of the vehicle 1.

[0068] The vehicle actuator 50 may include the engine of the vehicle 1 and, in some embodiments, may refer to an element that generates power for the vehicle 1 to travel. The drive operation unit 60 may include, for example, a steering wheel, a gear component, a braking device, etc., for the user to use to drive the vehicle 1. The vehicle starter 70 is a device for turning on / off the vehicle actuator 50 and may refer to, for example, a starter motor in the case of an internal combustion engine.

[0069] The vehicle 1 according to an embodiment may have an ISG (idle stop and go) system. The ISG system can be implemented through the control of the above control unit 20. For example, when the ISG mode entry condition is satisfied, the control unit 20 can stop the engine of the vehicle 1 or can turn off the engine. For example, when the condition for releasing the ISG mode entry is satisfied, the control unit 20 can restart the engine of the vehicle 1 or can turn on the engine. In this regard, a predetermined condition can be used as the ISG mode entry condition and the ISG mode entry release condition. Specific examples of one or more embodiments are described below as follows.

[0070] The user input sensor 11 can be controlled by the control unit 20 to be driven in a first mode driven by a first driving voltage or a second mode driven by a second driving voltage. The second driving voltage can be lower than the first driving voltage. For example, the first mode can be an activation mode that activates the function of the user input sensor 11. For example, the second mode can be an idle mode that only activates a specific predetermined function of the user input sensor 11. Due to various factors (such as differences in driving voltages), the power consumption of the user input sensor 11 in the first mode may be greater than the power consumption of the user input sensor 11 in the second mode. Therefore, when the second mode is used appropriately, the user input sensor 11 or the display panel 10 in the second mode can have significantly reduced power consumption. With the reduction of power consumption, the generation of electromagnetic waves is also reduced.

[0071] When operating in the first mode, the user input sensor 11 can generate a first sensing signal for sensing a change in the self-capacitance included in the user input sensor 11. For example, the first sensing signal can be a self-sensing signal that is used as a driving signal for touch recognition in special cases such as when there is moisture on the display panel 10. For example, the first sensing signal can be a driving signal mainly used for only sensing the presence of a user's touch input.

[0072] The user input sensor 11 in the first mode can also generate a second sensing signal for sensing a change in the mutual capacitance included in the user input sensor 11. For example, the second sensing signal can be a mutual-sensing signal that is used as a driving signal for general touch recognition. For example, the second sensing signal can be a driving signal mainly used for sensing position information about the user's touch input. For example, in the first mode, the user input sensor 11 can sense whether there is a user's touch input by using the first sensing signal, and can sense the user's touch position by using the second sensing signal.

[0073] When operating in the second mode, the user input sensor 11 may generate a first sensing signal for sensing a change in the self-capacitance included in the user input sensor 11. In this regard, the user input sensor 11 in the second mode may not generate a second sensing signal for sensing a change in the mutual capacitance included in the user input sensor 11. The second mode may be an idle mode that only waits for the first sensing signal. As a result, power for generating the second sensing signal can be saved. For example, in the second mode, the user input sensor 11 may sense whether there is a touch input from the user by using the first sensing signal. In the second mode, the user input sensor 11 may not use the second sensing signal and thus may not sense the touch position of the user. Accordingly, the power consumption per unit time of the user input sensor 11 in the first mode may be greater than the power consumption per unit time of the user input sensor 11 in the second mode. By appropriately increasing the time driven in the second mode, the power efficiency of the display panel 10 can be improved.

[0074] Figure 3 is a table schematically showing Figure 1 an example of the drive signal of the user input sensor 11. For reference, Figure 3 descriptions identical or overlapping with the above description may be omitted.

[0075] As Figure 3 shown in, in the first mode (activation mode), the reporting rate may be 113 Hz, the drive voltage applied to the touch electrode may be 9 V, and the number of pulse trains may be 90 ea. In the second mode (idle mode), the reporting rate may be 113 Hz, the drive voltage applied to the touch electrode may be 3 V, and the number of pulse trains may be 60 ea. As described above, as the amplitude of the drive voltage decreases and the number of pulse trains decreases, the power consumed by the user input sensor 11 in the second mode may be significantly reduced compared to the power consumed by the user input sensor 11 in the first mode.

[0076] Examples of changes in power and the like according to changes in the reporting rate, drive voltage, and number of pulse trains are summarized in Table 1.

[0077] Table 1

[0078]

[0079]

[0080] In Table 1, the reporting rate is the frequency at which the touch panel reports touch information to a computer or a controller (e.g., the control unit 20), and this can generally be measured in "hertz" (Hz), where "hertz" indicates the number of times touch information can be sent per second.

[0081] The drive voltage is the voltage used to activate the sensors of the touch panel and can provide the energy for the touch sensors to sense touches.

[0082] The number of pulse trains is the number of bundles of electrical signals sent by the sensors of the touch panel to sense touches, and more pulse trains generally mean higher sensing accuracy, but may also lead to increased power consumption and the amount of data to be processed.

[0083] As shown in [Table 1], in one embodiment, the optimal conditions of the user input sensor 11 in the second mode are as follows.

[0084] (1) Report rate = 226 Hz

[0085] (2) Drive voltage = 3 V

[0086] (3) Number of pulse trains = 15 ea

[0087] Compared with the user input sensor 11 driven in the first mode, the user input sensor 11 driven in the second mode under the above optimal conditions has the following advantages.

[0088] (1) EMI: 22.9 -> 7.6 (improvement of about 67%)

[0089] (2) Current consumption: 45 -> 5.2 (improvement of about 88%)

[0090] (3) Electrical stress: 30510 -> 10170 (improvement of about 67%)

[0091] Figure 4 is a flowchart showing an example of a method for driving Figure 1 the display panel 10. For reference, descriptions that are the same as or overlap with the above description may be omitted. Figure 4 of

[0092] As Figure 4 shown, according to an embodiment, the vehicle 1 or the control unit 20 of the vehicle 1 can turn on the ignition of the vehicle 1 (operation S1100), can drive the display panel 10 (user input sensor 11) in the first mode (operation S1200), can sense whether the vehicle 1 meets a preset condition (operation S1300), and when the vehicle 1 meets the preset condition, can drive the display panel 10 in the second mode (operation S1400). In this regard, driving the display panel 10 in the first mode or the second mode can be understood as driving or operating the user input sensor 11 in the first mode or the second mode. Therefore, when the second mode is appropriately used, the user input sensor 11 or the display panel 10 in the second mode can have significantly reduced power consumption. With the reduction of power consumption, the generation of electromagnetic waves is also reduced.

[0093] When the vehicle 1 does not meet the pre-set conditions, the vehicle 1 or the control unit 20 of the vehicle 1 according to the embodiment can continue to drive the display panel 10 in the first mode (operation S1200). Then, the vehicle 1 or the control unit 20 of the vehicle 1 can sense again whether the vehicle 1 meets the pre-set conditions (operation S1300).

[0094] The pre-set conditions can be one of the following conditions.

[0095] (1) The case where the vehicle 1 is traveling at a pre-set speed or higher

[0096] (2) The case where the driver's side door of the vehicle 1 is opened

[0097] (3) The case where no user input is sensed by the user input sensor 11 within a pre-set time

[0098] (4) The case where the vehicle 1 enters the ISG mode

[0099] After driving the display panel 10 in the second mode, the vehicle 1 or the control unit 20 can sense whether the pre-set conditions are released or a user input is received (operation S1500). After the pre-set conditions are released or a user input is received, the vehicle 1 or the control unit 20 can drive the display panel 10 in the first mode (operation S1600). Then, when the ignition of the vehicle 1 is turned off (operation S1700), the above series of processes ends.

[0100] For example, when the state of the vehicle 1 meets the pre-determined conditions after the ignition of the vehicle 1 is turned on, the user input sensor 11 can be driven in the second mode.

[0101] For example, when the vehicle 1 is traveling at a pre-set speed or higher after the ignition of the vehicle 1 is turned on, the user input sensor 11 can be driven in the second mode.

[0102] For example, when the driver's side door of the vehicle 1 is opened after the ignition of the vehicle 1 is turned on, the user input sensor 11 can be driven in the second mode.

[0103] For example, when no user input is sensed by the user input sensor 11 within a pre-set time after the ignition of the vehicle 1 is turned on, the user input sensor 11 can be driven in the second mode.

[0104] Figure 5 It is a flowchart showing an example of a method for driving Figure 1 the display panel 10. For reference, the descriptions that are the same as or overlap with the above description can be omitted. Figure 5 the above.

[0105] As shown in Figure 5 FIG. 1, the vehicle 1 or the control unit 20 of the vehicle 1 according to an embodiment may turn on the ignition of the vehicle 1 (operation S2100), may drive the display panel 10 (or the user input sensor 11) in a first mode (operation S2200), and may sense whether the vehicle 1 satisfies the ISG mode entry condition (operation S2300). When the vehicle 1 satisfies the ISG mode entry condition, the vehicle 1 may enter the ISG mode (operation S2400).

[0106] When the vehicle 1 enters the ISG mode, the vehicle 1 or the control unit 20 of the vehicle 1 may drive the display panel 10 in a second mode (operation S2500). After driving the display panel 10 in the second mode, the vehicle 1 or the control unit 20 of the vehicle 1 may sense whether the ISG mode of the vehicle 1 is released or a user input is received or input (operation S2600).

[0107] After the ISG mode is released or a user input is received or input, the vehicle 1 or the control unit 20 of the vehicle 1 may drive the display panel 10 in a first mode (operation S2700). Then, when the ignition of the vehicle 1 is turned off (operation S2800), the above series of processes ends. For example, when the ignition of the vehicle 1 is turned on, the user input sensor 11 may be driven in a first mode. For example, when the state of the vehicle 1 changes to the ISG entry state after the ignition of the vehicle 1 is turned on, the user input sensor 11 may be driven in a second mode. In addition, when the state of the vehicle 1 deviates from the ISG entry state, or a user input is sensed by the user input sensor 11, the user input sensor 11 may be driven in a first mode.

[0108] In one embodiment, the above ISG mode entry condition may be the following conditions, and all of the following conditions may be satisfied to enter the ISG mode.

[0109] (1) The state of turning on the ignition of the vehicle 1

[0110] (2) The state in which the vehicle 1 stops after traveling at a specific speed or higher

[0111] (3) The state in which the charge state of the battery has satisfied a predetermined standard

[0112] (4) The state in which a pressure of a predetermined magnitude has been applied to the brake pedal

[0113] The input conditions (1) to (4) are only given as examples. In other embodiments, different entry conditions may be used.

[0114] Figure 6It is a schematic perspective view of the display panel 10 according to an embodiment. For reference, descriptions of the display panel 10 that are the same as or overlap with the above description may be omitted.

[0115] As Figure 6 shown, since the display panel 10 according to an embodiment includes thin film transistors and at least one capacitor, the thin film transistors and at least one capacitor may be implemented by a conductive layer and an insulating layer.

[0116] The display panel 10 includes a display area DA and a peripheral area PA outside and surrounding the display area DA. Figure 6 The display area DA is shown having a rectangular shape, but one or more embodiments are not limited thereto. The display area DA may have various shapes, for example, a circular shape, an oval shape, a polygonal shape, or the shape of a specific figure.

[0117] The display area DA is an area for displaying an image, and a plurality of pixels PX may be arranged in the display area DA. Each pixel PX may include a display element such as an organic light emitting device. Each pixel PX may emit, for example, red light, green light, or blue light. Each pixel PX may be connected to a pixel circuit including one or more thin film transistors (TFTs) and at least one storage capacitor. The pixel circuit may be connected to a scan line SL configured to transmit a scan signal, a data line DL intersecting the scan line SL and configured to transmit a data signal, and a driving voltage line PL configured to provide a driving voltage. The data line DL and the driving voltage line PL may extend in a second direction D2, and the scan line SL may extend in a first direction D1. A third direction D3 is a direction intersecting the first direction D1 and the second direction D2.

[0118] The pixel PX may emit light having a luminance corresponding to an electrical signal output from the electrically connected pixel circuit. The display area DA may display a specific image by the light emitted from the pixel PX. For reference, the pixel PX may correspond to an emission area that emits light having at least one of red, green, and blue colors. In one embodiment, each pixel PX may include a plurality of sub-pixels that each emit light of a different color.

[0119] The peripheral area PA is an area in which no pixel PX is arranged, and thus may be an area where no image is displayed. Power supply lines for driving the pixel PX may be arranged in the peripheral area PA. In addition, pads may be arranged in the peripheral area PA, and a PCB including a driving circuit portion or an IC device such as a driver IC may be electrically connected to the pads in the peripheral area PA. For reference, since the display panel 10 includes a substrate 100 (e.g., Figure 8(substrate 100), so the substrate 100 may also have a display area DA and a peripheral area PA. A detailed description of the substrate 100 will be given later.

[0120] In addition, a plurality of transistors may be arranged in the display area DA. Among the plurality of transistors, depending on the type of transistor (N-type or P-type) and / or operating conditions, the first terminal of the transistor may be a source electrode or a drain electrode, and the second terminal of the transistor may be an electrode different from the first terminal. For example, when the first terminal is a source electrode, the second terminal may be a drain electrode.

[0121] For example, the plurality of transistors may include a driving transistor, a data writing transistor, a compensating transistor, an initializing transistor, and an emission control transistor. The driving transistor may be connected between a driving voltage line PL and an organic light emitting device, and the data writing transistor may be connected to a data line DL and the driving transistor, and may be configured to perform a switching operation for transmitting a data signal transmitted through the data line DL.

[0122] The compensating transistor may be turned on according to a scan signal received through a scan line SL to connect the driving transistor and the organic light emitting device to each other, thereby compensating for the threshold voltage of the driving transistor.

[0123] The initializing transistor may be turned on according to a scan signal received through the scan line SL to transmit an initializing voltage to the gate electrode of the driving transistor, thereby initializing the gate electrode of the driving transistor. The scan line connected to the initializing transistor may be a separate scan line different from the scan line connected to the compensating transistor.

[0124] The emission control transistor may be turned on according to an emission control signal received through an emission control line. As a result, a driving current may flow through the organic light emitting device.

[0125] The organic light emitting device may include a pixel electrode (e.g., an anode) and a counter electrode (e.g., a cathode), and may receive a voltage from the pixel electrode (e.g., an anode) and the counter electrode (e.g., a cathode). The organic light emitting device may receive a driving current from the driving transistor and emit light, thereby displaying an image.

[0126] Although the organic light emitting display device will be described below as an example of a display device according to an embodiment, the display device described herein is not limited thereto. In another embodiment, the display device described herein may be, for example, an inorganic light emitting display (or an inorganic electroluminescent (EL) display) or a quantum dot light emitting display. For example, the emission layer of the display element included in the display device may include an organic material or an inorganic material. Alternatively, the display device may include an emission layer and quantum dots positioned on a path of light emitted from the emission layer.

[0127] Figure 7 Schematically shows Figure 6 an equivalent circuit diagram of pixels PX of a display panel. For reference, descriptions that are the same as or overlap with the above description may be omitted Figure 7

[0128] As Figure 7 shown in, each pixel PX includes a pixel circuit PC connected to a scan line SL and a data line DL, and an organic light-emitting device OLED connected to the pixel circuit PC. For example, the pixel circuit PC includes a driving TFT T1, a switching TFT T2, and a storage capacitor Cst. The switching TFT T2 is connected to the scan line SL and the data line DL, and is configured to transmit a data signal Dm input through the data line DL to the driving TFT T1 according to a scan signal Sn input through the scan line SL

[0129] For example, the storage capacitor Cst is connected to a node between the switching TFT T2 and the driving TFT T1 and a driving voltage line PL. The storage capacitor Cst stores a voltage corresponding to the difference between the voltage received from the switching TFT T2 and a first power voltage (or referred to as a driving voltage) ELVDD provided to the driving voltage line PL

[0130] For example, the driving TFT T1 may be connected to the driving voltage line PL and the storage capacitor Cst, and may be configured to control a driving current I flowing through the organic light-emitting device OLED from the driving voltage line PL in response to a voltage value stored in the storage capacitor Cst OLED . The organic light-emitting device OLED may emit light with a specific luminance according to the driving current I OLED

[0131] The organic light-emitting device OLED may receive a second power voltage (or referred to as a common voltage) ELVSS. For example, the organic light-emitting device OLED may receive the second power voltage (or referred to as a common voltage) ELVSS through a counter electrode (e.g., a cathode), and the organic light-emitting device OLED may emit light with a specific luminance according to a driving current I caused by a voltage difference between the first power voltage (or referred to as a driving voltage) ELVDD and the second power voltage (or referred to as a common voltage) ELVSS OLED

[0132] Figure 7 Illustrates a case where the pixel circuit PC includes two TFTs and one storage capacitor, but one or more embodiments are not limited thereto. For example, the pixel circuit PC may include two or more storage capacitors, and may also include three or more TFTs

[0133] Figure 8 Schematically shows Figure 6 ​​​A cross-sectional view of the periphery of a pixel of the display panel. For reference, it may be omitted Figure 8 Descriptions that are the same as or overlap with the above description.

[0134] As described above, the substrate 100 may include regions corresponding to the display area DA and the peripheral area PA outside the display area DA. The substrate 100 may include various flexible or bendable materials. For example, the substrate 100 may include glass, metal, or polymer resin. In addition, the substrate 100 may include polymer resins such as polyethersulfone, polyacrylate, polyetherimide, polyethylene naphthalate, polyethylene terephthalate, polyphenylene sulfide, polyarylate, polyimide, polycarbonate, or cellulose acetate propionate. For example, the substrate 100 may be differently modified to have a multilayer structure including multiple (e.g., two) layers and a barrier layer between the multiple layers. Each of the multiple layers may include the above polymer resins, and the barrier layer may include inorganic materials (e.g., silicon oxide, silicon nitride, silicon oxynitride, etc.).

[0135] The buffer layer 101 may be on the substrate 100. The buffer layer 101 may be used as a barrier layer and / or a blocking layer to prevent the diffusion of impurity ions, prevent the penetration of moisture or external air, and planarize the surface. For example, the buffer layer 101 may include silicon oxide, silicon nitride, or silicon oxynitride. In addition, the buffer layer 101 may adjust the rate of heat supply during the crystallization process for forming the semiconductor layer 110, so as to crystallize the semiconductor layer 110 uniformly.

[0136] The semiconductor layer 110 may be on the buffer layer 101. The semiconductor layer 110 may be formed of polysilicon and may include a channel region doped with no impurities and source and drain regions formed on both sides of the channel region and doped with impurities. In this regard, the impurities vary according to the type of TFT and may be N-type impurities or P-type impurities.

[0137] The gate insulating layer 102 may be on the semiconductor layer 110. The gate insulating layer 102 may be an element for providing insulation between the semiconductor layer 110 and the first gate layer 120a. The gate insulating layer 102 may include inorganic materials (e.g., silicon oxide, silicon nitride, and / or silicon oxynitride) and may be disposed between the semiconductor layer 110 and the first gate layer 120a. In addition, the gate insulating layer 102 may have a structure corresponding to the entire surface of the substrate 100 and may have a structure in which contact holes are formed in a preset portion. Such an insulating layer including inorganic materials may be formed, for example, by chemical vapor deposition (CVD) or atomic layer deposition (ALD). This also applies to the embodiments and their modifications described below.

[0141] The second gate layer 120b may form the storage capacitor Cst described above together with the first gate layer 120a. For example, the first gate layer 120a may be one electrode of the storage capacitor Cst, and the second gate layer 120b may be the other electrode of the storage capacitor Cst. When observed in a direction perpendicular to the substrate 100, the area of the second gate layer 120b may be larger than the area of the first gate layer 120a. Optionally, when observed in a direction perpendicular to the substrate 100, the second gate layer 120b may cover the first gate layer 120a. Figure 7

[0142] ​The second interlayer insulating layer 103b may be positioned over the second gate layer 120b. The second interlayer insulating layer 103b may cover the second gate layer 120b.

In some embodiments, the second interlayer insulating layer 103b may have a SiO x / SiN y or SiN x / SiO y dual structure.

[0143] The first conductive layer 130 may be on the second interlayer insulating layer 103b and penetrate the second interlayer insulating layer 103b.

The second organic insulating layer 105 may be an organic insulating layer having a substantially flat top surface while covering the top surface of the second conductive layer 140, and thus serves as a planarizing layer. The second organic insulating layer 105 may include an organic material such as, for example, acrylic, BCB, or HMDSO. For example, the second organic insulating layer 105 may be differently modified to have a single-layer structure or a multi-layer structure.

[0147] The organic insulating layer OL may include the first organic insulating layer 104 and the second organic insulating layer 105. In addition, the organic insulating layer OL may be an element further including additional insulating layers described below.

[0148] In addition, an additional conductive layer and an additional insulating layer may be provided between the conductive layer and the pixel electrode 150, and may be applied to various embodiments.

The pixel electrode 150 may be connected to the second conductive layer 140 through a contact hole in the second organic insulating layer 105. A display element (or a light-emitting layer) may be on the pixel electrode 150. An organic light-emitting device OLED (for example, see Figure 7 ) may serve as the display element. That is, the organic light-emitting device OLED may be interposed on, for example, the pixel electrode 150. The pixel electrode 150 may include a transmissive conductive layer formed of a transmissive conductive oxide such as ITO, In2O3, or IZO, and a reflective layer formed of a metal such as Al or Ag.

For example, at least one of the layers constituting the intermediate layer 160 may be formed as a single body like the counter electrode 170. In another embodiment, the intermediate layer 160 may include layers patterned to correspond to each of the plurality of pixel electrodes 150.

[0154] The counter electrode 170 may be disposed in the display area DA and may be disposed over the entire display area DA. For example, the counter electrode 170 may be formed as a single body to cover a plurality of pixels. The counter electrode 170 may be in electrical contact with a common power line disposed in the peripheral area PA. In an embodiment, the counter electrode 170 may extend to the barrier rib. The thin film encapsulation layer TFE may cover the entire display area DA and may extend toward the peripheral area PA to cover at least a portion of the peripheral area PA.

[0169] The touch sensing layer YTL is disposed on the thin film encapsulation layer TFE (for example, see Figure 8 ). The touch sensing layer YTL can sense an external input (e.g., a user's touch) and obtain information about the position or intensity of the external input. The touch sensing layer YTL can include a plurality of sensing lines SL1 and SL2 and a plurality of sensing pads PDT.

[0170] The touch sensing layer YTL can include a sensing area SA and a non-sensing area NSA. The sensing area SA can be an area capable of sensing an external input. The sensing area SA can overlap with the display area DA. In the present embodiment, the effective area can be an area including the sensing area SA and the display area DA.

[0171] The non-sensing area NSA is adjacent to the sensing area SA. The non-sensing area NSA can at least partially or completely surround the edge of the sensing area SA. The non-sensing area NSA that completely surrounds the sensing area SA is shown only as an example. In one embodiment, the non-sensing area NSA can be adjacent to only a part of the edge of the sensing area SA or can be omitted.

[0172] The sensing electrode SS is disposed in the sensing area SA. The sensing electrode SS can include a first sensing electrode SP1 and a second sensing electrode SP2 that receive different electrical signals. The sensing electrode SS can obtain information about an external input by a change in capacitance between the first sensing electrode SP1 and the second sensing electrode SP2.

[0173] The first sensing electrode SP1 extends in the first direction D1. The first sensing electrode SP1 can include a plurality of first sensing electrodes SP1, and the plurality of first sensing electrodes SP1 can be separated from each other in the second direction D2. The second sensing electrode SP2 extends in the second direction D2. The second sensing electrode SP2 can include a plurality of second sensing electrodes SP2, and the plurality of second sensing electrodes SP2 can be separated from each other in the first direction D1.

[0174] The sensing lines SL1 and SL2 and the sensing pads PDT are arranged in the non-sensing area NSA. The sensing pads PDT are respectively connected to the sensing lines SL1 and SL2. The sensing lines SL1 and SL2 include a first sensing line SL1 and a second sensing line SL2. The first sensing line SL1 is configured to transmit an electrical signal, such as an electrical signal provided from a host through the sensing pad PDT, to the first sensing electrode SP1 by connecting the first sensing electrode SP1 and the sensing pad PDT to each other. The second sensing line SL2 is configured to transmit an electrical signal provided from the outside through the sensing pad PDT to the second sensing electrode SP2 by connecting the second sensing electrode SP2 and the sensing pad PDT to each other. The sensing pads PDT in the non-sensing area NSA can be electrically connected to other pads of the display panel 10.

[0175] In addition, an example of the display panel 10 is as follows.

[0176] Refer again to Figure 1 and Figure 2 , in an embodiment, the display panel 10 can be the display panel 10 controlled by the control unit 20 of the vehicle 1. More specifically, the control unit 20 of the vehicle 1 can control the driving driver 11b of the display panel 10.

[0177] The display panel 10 can include a substrate including a display area and a peripheral area. The display panel 10 can include a plurality of touch sensors 11a and a driving driver 11b on the substrate. More specifically, the plurality of touch sensors 11a can be arranged in the display area of the substrate. The driving driver 11b configured to drive the touch sensors 11a can be arranged in the peripheral area of the substrate.

[0178] The driving driver 11b can be controlled by the control unit 20 of the vehicle 1. The driving driver 11b can be controlled by the control unit 20 of the vehicle 1 to be driven in a first mode driven by a first driving voltage or a second mode driven by a second driving voltage, where the second driving voltage is lower than the first driving voltage.

[0179] For example, in the first mode, the driving driver 11b can generate a first sensing signal for sensing a change in the self-capacitance included in the plurality of touch sensors 11a. In addition, in the first mode, the driving driver 11b can generate a second sensing signal for sensing a change in the mutual capacitance (and thus the corresponding touch position) included in the plurality of touch sensors 11a.

[0180] For example, in the second mode, the driving driver 11b can generate a first sensing signal for sensing a change in the self-capacitance included in the plurality of touch sensors 11a, and can not generate a second sensing signal for sensing a change in the mutual capacitance included in the plurality of touch sensors 11a.

[0181] For example, when the ignition of vehicle 1 is turned on, the drive driver 11b can be driven in the first mode.

[0182] For example, when the state of vehicle 1 switches to the ISG entry state after the ignition of vehicle 1 is turned on, the drive driver 11b can be driven in the second mode.

[0183] For example, when the state of vehicle 1 deviates from the ISG entry state or a user input is sensed by the touch sensor 11a, the drive driver 11b can be driven in the first mode.

[0184] For example, when the drive driver 11b is in the first mode, the touch sensor 11a can sense whether there is a user's touch input and the position of the user's touch.

[0185] For example, when the drive driver 11b is in the second mode, the touch sensor 11a can sense whether there is a user's touch input and may not sense the position of the user's touch.

[0186] In addition, a control method for a display device according to an embodiment is as follows.

[0187] For ease of explanation, content that is the same as or overlaps with the above is omitted, and those skilled in the art can easily understand that the above can be similarly applied to the control method of the display device according to the embodiment.

[0188] A control method for a display device according to an embodiment may include: driving a touch sensor in a first mode; determining whether at least one preset condition of the vehicle is satisfied; and if the at least one preset condition is met, driving the touch sensor in a second mode.

[0189] For example, in the first mode, the touch sensor generates a first sensing signal for sensing a change in self-capacitance and a second sensing signal for sensing a change in mutual capacitance. The power consumption in the first mode is greater than that in the second mode.

[0190] The first sensing signal is generated based on the user's touch, and the second sensing signal is generated based on the position of the touch.

[0191] The touch sensor is driven by a first driving voltage in the first mode, and the touch sensor is driven by a second driving voltage in the second mode, and the second driving voltage is less than the first driving voltage. The number of pulse trains in the second mode is less than the number of pulse trains in the first mode.

[0192] At least one preset condition is one of the following conditions:

[0193] The case where the vehicle is traveling at a preset speed or higher,

[0194] The case where the door of the vehicle is open,

[0195] The case where no user input is sensed by the touch sensor within a preset time, and

[0196] The case where the vehicle enters the idle stop and go (ISG) mode.

[0197] According to one or more of the above embodiments, a display device for efficient power consumption and a vehicle including a display panel can be implemented. However, one or more embodiments are not limited by such effects.
