[0049] The first display area AA1 may include gate lines GL, data lines DL, transmit lines EL, and pixels PX electrically connected to the gate lines GL, data lines DL, and transmit lines EL. The gate lines GL and the data lines DL may extend in directions intersecting each other.
[0050] The main drive controller 200A may receive input image data IMG and input control signals CONT from a main processor (e.g., an application processor and / or a graphics processing unit, etc.). For example, the input image data IMG may include red image data, green image data, and blue image data. For example, the input image data IMG may include white image data. For example, the input image data IMG may include magenta image data, yellow image data, and cyan image data. The input control signals CONT may include a main clock signal and a data enable signal. The input control signals CONT may further include a vertical synchronization signal and a horizontal synchronization signal. The main drive controller 200A may output a common logic signal LOGS to the first slave drive controller 200B (refer to Figure 3 ).
[0051] The main drive controller 200A can generate a first control signal CONT1, a second control signal CONT2, a third control signal CONT3, a fourth control signal CONT4, and a data signal DATA based on the input image data IMG and the input control signal CONT. In an embodiment, the main drive controller 200A can generate a fifth control signal CONT5 based on the input image data IMG and the input control signal CONT.
[0052] The main drive controller 200A can generate a first control signal CONT1 for controlling the operation of the gate driver 300 based on the input control signal CONT, and output the first control signal CONT1 to the gate driver 300. The first control signal CONT1 can include a vertical start signal and a scan clock signal.

[0054] The main drive controller 200A generates a second control signal CONT2 for controlling the operation of the data driver 500 based on the input control signal CONT, and outputs the second control signal CONT2 to the data driver 500. The second control signal CONT2 can include a horizontal start signal and a load signal.
[0055] The main drive controller 200A can generate a data signal DATA based on the input image data IMG and the input control signal CONT. The main drive controller 200A can output the data signal DATA to the data driver 500.
[0056] The main drive controller 200A can generate a fourth control signal CONT4 for controlling the operation of the emission driver 600 based on the input control signal CONT. The main drive controller 200A can output the fourth control signal CONT4 to the emission driver 600.
[0057] The main drive controller 200A can generate a fifth control signal CONT5 for controlling the operation of the sensing driver 700 based on the input control signal CONT, and output the fifth control signal CONT5 to the sensing driver 700.
[0058] The gate driver 300 can generate a gate signal for driving the gate line GL in response to the first control signal CONT1 received from the main drive controller 200A. The gate driver 300 can output the gate signal to the gate line GL of at least one of the display areas (e.g., the first display area AA1, the second display area AA2, etc.).
[0059] The gamma reference voltage generator 400 may generate a gamma reference voltage VGREF in response to a third control signal CONT3 received from the main driving controller 200A. The gamma reference voltage generator 400 may provide the gamma reference voltage VGREF to the data driver 500. The gamma reference voltage VGREF has a value corresponding to each of the data signals DATA. For example, the gamma reference voltage generator 400 may be disposed in the main driving controller 200A or in the data driver 500.
[0060] The data driver 500 may receive a second control signal CONT2 and data signals DATA from the main driving controller 200A, and receive the gamma reference voltage VGREF from the gamma reference voltage generator 400. The data driver 500 may convert the data signals DATA into data voltages VDATA of an analog type using the gamma reference voltage VGREF. The data driver 500 may output the data voltage VDATA to the data lines DL.
[0061] In an embodiment, the data driver 500 may be implemented with one or more integrated circuits. In another embodiment, the data driver 500 and the main driving controller 200A may be implemented as a single integrated circuit, and the single integrated circuit may be referred to as a timing controller embedded data driver (TED).
[0062] The emission driver 600 may generate an emission signal for driving the emission lines EL in response to a fourth control signal CONT4 received from the main driving controller 200A. The emission driver 600 may output the emission signal to the emission lines EL of at least one of the display areas (e.g., the first display area AA1, the second display area AA2, etc.).
[0063] In an embodiment of the inventive concept, the emission driver 600 may be integrated in the peripheral area of the display panel 100. In an embodiment of the inventive concept, the emission driver 600 may be mounted in the peripheral area of the display panel 100.
[0064] Although, for ease of explanation, in Figure 2 the gate driver 300 is disposed on the first side of the display panel 100 and the emission driver 600 is disposed on the second side of the display panel 100, the inventive concept is not limited thereto. The gate driver 300 and the emission driver 600 may be disposed on the first side of the display panel 100. For example, the gate driver 300 and the emission driver 600 may be disposed in the peripheral area on the same side of the display area of the display panel 100. For example, the gate driver 300 and the emission driver 600 may be integrally formed with each other.
[0065] In an embodiment, the sensing driver 700 may receive a fifth control signal CONT5 from the main drive controller 200A. The sensing driver 700 may generate sensing data SD by sensing pixels PX via sensing lines SL. For example, the sensing driver 700 may sense the driving characteristics (e.g., mobility and / or threshold voltage) of driving transistors of pixels PX by measuring sensing currents (or sensing voltages) of the driving transistors via the sensing lines SL. For example, the operation of sensing the driving characteristics (e.g., mobility and / or threshold voltage) of the sensing driving transistors may be referred to as a sensing operation.
[0066] In an embodiment, the sensing driver 700 may be implemented with one or more integrated circuits. In another embodiment, the sensing driver 700 may be disposed in the data driver 500 or the main drive controller 200A.
[0067] In addition, in an embodiment, the main panel driver 110A may not include the sensing driver 700. The inventive concept is not limited to the types of drivers that the main panel driver 110A may include.
[0068] Figure 3 is a block diagram of Figure 1 the second display area AA2 of the display device and the first sub-panel driver 110B.
[0069] Referring to Figure 3 , except that the first sub-panel driver 110B may include a first sub-drive controller 200B, the first sub-panel driver 110B is substantially the same as Figure 2 the main panel driver 110A. The first sub-drive controller 200B does not generate a common logic signal LOGS, and the first sub-drive controller 200B receives the common logic signal LOGS from the main drive controller 200A (refer to Figure 2 ). The same reference numerals will be used to refer to the same elements, and any repeated explanations of the above elements will be omitted.
[0070] In addition, in an embodiment, the first sub-panel driver 110B may not include the sensing driver 700. Although the main panel driver 110A and the first sub-panel driver 110B are depicted as having separate embodiments, in some embodiments, some components such as the gate driver 300 and the emission driver 600 may be shared by the first display area AA1 and the second display area AA2. The inventive concept is not limited to the types of drivers that the first sub-panel driver 110B may include.
[0071] Figure 4 is a block diagram showing the main drive controller 200A included in the Figure 1 main panel driver 110A and the Figure 1Block diagram of the first slave drive controller 200B in the first slave panel driver 110B. Figure 5 It shows the drive circuit included in Figure 4 the main drive controller 200A of Figure 4 and the drive circuit included in the first slave drive controller 200B of
[0072] Refer to Figures 1 to 5 , the main drive controller 200A can output a common logic signal LOGS to the first slave drive controller 200B.
[0073] In this embodiment, the main drive controller 200A may include a first main drive circuit MIP1, a second main drive circuit MIP2, and a third main drive circuit MIP3. The first slave drive controller 200B may include a first - first slave drive circuit SIP1, a first - second slave drive circuit SIP2, and a first - third slave drive circuit SIP3.
[0074] In this embodiment, the main panel driver 110A and the first slave panel driver 110B may perform the same operations. The same operations may be referred to as "common operations". For example, the common operations may include a brightness control operation, a sensing operation, and an operation of changing the data signal DATA based on the sensed data SD (e.g., an external compensation operation). For example, the common operations may include an operation of determining a deteriorated area of the display panel 100, an operation of changing the data signal DATA, an operation of changing the driving frequency of the display panel 100, etc. However, the inventive concept is not limited to the operations included in the common operations of the panel drivers (e.g., the main panel driver 110A and the first slave panel driver 110B). In an embodiment, the input control signal CONT may include a signal for determining the common operations.
[0075] In this embodiment, the first main drive circuit MIP1 may generate a signal for performing a first driving operation. For example, the first driving operation may be a brightness control operation. However, the inventive concept is not limited to the type of the first driving operation. For example, the first driving operation may be an external compensation operation. The first driving operation may be set by the user.
[0076] In the present embodiment, when the first driving operation is performed by the main panel driver 110A and the first slave panel driver 110B, the first main driving circuit MIP1 may generate a common logic signal LOGS (e.g., the first common logic signal). The common logic signal LOGS (e.g., the first common logic signal) may be a signal for the main panel driver 110A and the first slave panel driver 110B to perform the first driving operation. In the present embodiment, the first-first slave driving circuit SIP1 may not generate the common logic signal LOGS (e.g., the first common logic signal). When the first driving operation is a common operation, the first-first slave driving circuit SIP1 may remain inactive. The first slave panel driver 110B may perform the first driving operation in response to the common logic signal LOGS.
[0077] In the present embodiment, the second main driving circuit MIP2 may generate a signal for performing a second driving operation. For example, the second driving operation may be a sensing operation. However, the inventive concept does not limit the second driving operation to any specific type of operation. For example, the second driving operation may be an operation of determining a deteriorated area of the display panel 100. For example, the second driving operation may be referred to as a brightness control operation. The second driving operation may be set by a user.
[0078] In the present embodiment, when the second driving operation is performed by the main panel driver 110A and the first slave panel driver 110B, the second main driving circuit MIP2 may generate a common logic signal LOGS (e.g., the second common logic signal). The common logic signal LOGS (e.g., the second common logic signal) may be a signal for the main panel driver 110A and the first slave panel driver 110B to perform the second driving operation. In the present embodiment, the first-second slave driving circuit SIP2 may not generate the common logic signal LOGS (e.g., the second common logic signal). When the second driving operation is a common operation, the first-second slave driving circuit SIP2 may remain inactive. The first slave panel driver 110B may perform the second driving operation in response to the common logic signal LOGS.
[0079] In the present embodiment, the third main driving circuit MIP3 may generate a signal for performing a third driving operation. For example, the third driving operation may be an external compensation operation. However, the inventive concept does not limit the third driving operation to any specific type of operation. For example, the third driving operation may be an operation of changing the data signal DATA. For example, the third driving operation may be referred to as a sensing operation. The third driving operation may be set by a user.
[0080] In the present embodiment, when the third driving operation is performed by the main panel driver 110A and the first slave panel driver 110B, the third main driving circuit MIP3 may generate a common logic signal LOGS. The common logic signal LOGS may be a signal for the main panel driver 110A and the first slave panel driver 110B to perform the third driving operation. In the present embodiment, the first - third slave driving circuits SIP3 may not generate the common logic signal LOGS. When the third driving operation is a common operation, the first - third slave driving circuits SIP3 may remain inactive. The first slave panel driver 110B may perform the third driving operation in response to the common logic signal LOGS.
[0081] In an embodiment, the third driving operation is performed by the main panel driver 110A instead of the first slave panel driver 110B, and the main panel driver 110A may not output the common logic signal LOGS. For example, when the third driving operation is not a common operation, the third main driving circuit MIP3 may not generate the common logic signal LOGS.
[0082] In the present embodiment, the main panel driver 110A and the first slave panel driver 110B may perform a common operation in response to the common logic signal LOGS. For example, when the first driving operation is a common operation, the common logic signal LOGS may be a signal for triggering the first driving operation. For example, when the first driving operation and the second driving operation are common operations, the common logic signal LOGS may include a signal for triggering the first driving operation and a signal for triggering the second driving operation. In the present embodiment, the common logic signal LOGS may be generated from the main driving controller 200A. The first slave driving controller 200B may not generate the common logic signal LOGS.
[0083] In the present embodiment, the common logic signal LOGS may be applied during a blank period of the first slave panel driver 110B.
[0084] In a conventional display device, a conventional main driving controller may generate a signal for performing a common operation. A conventional slave driving controller may also generate a signal for performing a common operation.
[0085] In contrast, in a display device according to the inventive concept, the main driving controller 200A may generate the common logic signal LOGS, but the first slave driving controller 200B may not generate the common logic signal LOGS. Accordingly, power consumption of the display device according to the inventive concept may be reduced.
[0086] In an embodiment, the main drive controller 200A may output a drive data signal different from the common logic signal LOGS to the first slave drive controller 200B. In addition, the first slave drive controller 200B may output a drive data signal to the main drive controller 200A. However, the inventive concept is not limited to the type of drive data signal.

For example, the main detailed arithmetic logic circuit may be a circuit that generates signals (e.g., main detailed logic signals) that cause the main panel driver 110A and the first slave panel driver 110B to perform different operations from each other. For example, the main detailed arithmetic logic circuit may generate signals that cause the first main detailed arithmetic logic circuit MLOG1, the second main detailed arithmetic logic circuit MLOG2, the third main detailed arithmetic logic circuit MLOG3, the fourth main detailed arithmetic logic circuit MLOG4, the fifth main detailed arithmetic logic circuit MLOG5, the sixth main detailed arithmetic logic circuit MLOG6, and the first slave panel driver 110B to perform different operations. For example, the different operations may be operations to change the driving frequency. For example, the first slave detailed arithmetic logic circuit may be a circuit that generates signals (e.g., first slave detailed logic signals) that cause the main panel driver 110A and the first slave panel driver 110B to perform different operations.

The first-first-fifth slave detailed arithmetic logic circuit may generate a signal for executing the first-fifth detailed operation.

[0093] For example, when the first driving operation is a brightness control operation, the first-first detailed operation may be an operation of controlling a predetermined area of the first display area AA1. In addition, the first-second detailed operation is an operation of increasing or decreasing the brightness of the first display area AA1. The first-third detailed operation is an operation of increasing or decreasing the brightness of another predetermined area of the first display area AA1. For example, when the first driving operation is a brightness control operation, the first-first detailed operation may be an operation of controlling a predetermined area of the second display area AA2. In addition, the first-second detailed operation is an operation of increasing or decreasing the brightness of the second display area AA2. The first-third detailed operation is an operation of increasing or decreasing the brightness of another predetermined area of the second display area AA2. However, the inventive concept is not limited to the operations of the first-first detailed operation to the first-third detailed operation included in the first driving operation. For example, the first-first detailed operation to the first-sixth detailed operation may be set by the user.

In this case, the first-first main detailed arithmetic logic circuit, the first-fifth main detailed arithmetic logic circuit, and the first-sixth main detailed arithmetic logic circuit may be a common logic circuit CLOG.

[0095] Figure 8Illustrates an example where the first - second detailed operations and the first - third detailed operations are common operations. In this case, the first - second main detailed arithmetic logic circuits and the first - third main detailed arithmetic logic circuits, the first - first - second slave detailed arithmetic logic circuits and the first - first - third slave detailed arithmetic logic circuits can be the common logic circuit CLOG. The first - second main detailed arithmetic logic circuits and the first - third main detailed arithmetic logic circuits can generate a common logic signal LOGS.

[0101] For example, when the second driving operation is a sensing operation, the second - first detailed operation can be an operation of sensing a predetermined area of the display panel 100. In addition, the second - second detailed operation is an operation of sensing the display panel 100 in real time. The second - third detailed operation is an operation of changing the data voltage VDATA. However, the inventive concept is not limited to the operations of the second - first detailed operation to the second - third detailed operation included in the second driving operation. For example, the second - first detailed operation to the second - sixth detailed operation can be set by the user.
[0102] In Figure 7 the example, the second - first detailed operation, the second - fifth detailed operation, and the second - sixth detailed operation are common operations. In this case, the second - first main detailed operation logic circuit, the second - fifth main detailed operation logic circuit, and the second - sixth main detailed operation logic circuit can be a common logic circuit CLOG. Therefore, the second - first main detailed operation logic circuit, the second - fifth main detailed operation logic circuit, and the second - sixth main detailed operation logic circuit can generate a common logic signal LOGS. In addition, the first - second - first slave detailed operation logic circuit, the first - second - fifth slave detailed operation logic circuit, and the first - second - sixth slave detailed operation logic circuit can be a common logic circuit CLOG. The first - second - first slave detailed operation logic circuit, the first - second - fifth slave detailed operation logic circuit, and the first - second - sixth slave detailed operation logic circuit may not generate a common logic signal LOGS. The first panel driver 110B can execute the second - first detailed operation, the second - fifth detailed operation, and the second - sixth detailed operation in response to the common logic signal LOGS received from the second - first main detailed operation logic circuit, the second - fifth main detailed operation logic circuit, and the second - sixth main detailed operation logic circuit.
[0103] In Figure 8In the example, the second-second detailed operation and the second-third detailed operation are common operations. In this case, the second-second main detailed arithmetic logic circuit and the second-third main detailed arithmetic logic circuit, the first-second-second slave detailed arithmetic logic circuit and the first-second-third slave detailed arithmetic logic circuit can be the common logic circuit CLOG. The second-second main detailed arithmetic logic circuit and the second-third main detailed arithmetic logic circuit can generate a common logic signal LOGS. The first-second-second slave detailed arithmetic logic circuit and the first-second-third slave detailed arithmetic logic circuit may not generate the common logic signal LOGS.
[0104] The first slave panel driver 110B can perform the second-second detailed operation and the second-third detailed operation in response to the common logic signal LOGS received from the second-second main detailed arithmetic logic circuit and the second-third main detailed arithmetic logic circuit.
[0105] For example, the third main drive circuit MIP3 can include a third-first main detailed arithmetic logic circuit, a third-second main detailed arithmetic logic circuit, a third-third main detailed arithmetic logic circuit, a third-fourth main detailed arithmetic logic circuit, a third-fifth main detailed arithmetic logic circuit, and a third-sixth main detailed arithmetic logic circuit.
[0106] In the present embodiment, the third drive operation can include a third-first detailed operation to a third-sixth detailed operation. The third-first main detailed arithmetic logic circuit can generate a signal for causing the execution of the third-first detailed operation. The third-second main detailed arithmetic logic circuit can generate a signal for causing the execution of the third-second detailed operation. The third-third main detailed arithmetic logic circuit can generate a signal for causing the execution of the third-third detailed operation. The third-fourth main detailed arithmetic logic circuit can generate a signal for causing the execution of the third-fourth detailed operation. The third-fifth main detailed arithmetic logic circuit can generate a signal for causing the execution of the third-fifth detailed operation. The third-sixth main detailed arithmetic logic circuit can generate a signal for causing the execution of the third-sixth detailed operation.
[0107] The first-third slave drive circuit SIP3 can include a first slave detailed arithmetic logic circuit to a sixth slave detailed arithmetic logic circuit. For example, the first-third slave drive circuit SIP3 can include a first-third-first slave detailed arithmetic logic circuit, a first-third-second slave detailed arithmetic logic circuit, a first-third-third slave detailed arithmetic logic circuit, a first-third-fourth slave detailed arithmetic logic circuit, a first-third-fifth slave detailed arithmetic logic circuit, and a first-third-sixth slave detailed arithmetic logic circuit.
[0108] The first - third - first slave detailed arithmetic logic circuit can generate a signal that causes the execution of the third - first detailed operation. The first - third - second slave detailed arithmetic logic circuit can generate a signal that causes the execution of the third - second detailed operation. The first - third - third slave detailed arithmetic logic circuit can generate a signal that causes the execution of the third - third detailed operation. The first - third - fourth slave detailed arithmetic logic circuit can generate a signal that causes the execution of the third - fourth detailed operation. The first - third - fifth slave detailed arithmetic logic circuit can generate a signal that causes the execution of the third - fifth detailed operation. The first - third - sixth slave detailed arithmetic logic circuit can generate a signal that causes the execution of the third - sixth detailed operation.
[0109] For example, when the third driving operation is an external compensation operation, the third - first detailed operation can be an external compensation operation performed on a predetermined area of the display panel 100. In addition, the third - second detailed operation is an operation of storing the sensed data SD. The third - third detailed operation is an operation of generating the data signal DATA based on the sensed data SD. However, the inventive concept is not limited to the operations of the third - first detailed operation to the third - third detailed operation included in the third driving operation. For example, the third - first detailed operation to the third - sixth detailed operation can be set by the user.
[0110] For example, the third - first detailed operation, the third - fifth detailed operation, and the third - sixth detailed operation are common operations, and the third - first main detailed arithmetic logic circuit, the third - fifth main detailed arithmetic logic circuit, and the third - sixth main detailed arithmetic logic circuit can be a common logic circuit CLOG. Therefore, the third - first main detailed arithmetic logic circuit, the third - fifth main detailed arithmetic logic circuit, and the third - sixth main detailed arithmetic logic circuit can generate a common logic signal LOGS. In addition, the first - third - first slave detailed arithmetic logic circuit, the first - third - fifth slave detailed arithmetic logic circuit, and the first - third - sixth slave detailed arithmetic logic circuit can be a common logic circuit CLOG. The first - third - first slave detailed arithmetic logic circuit, the first - third - fifth slave detailed arithmetic logic circuit, and the first - third - sixth slave detailed arithmetic logic circuit may not generate a common logic signal LOGS. The first slave panel driver 110B can execute the third - first detailed operation, the third - fifth detailed operation, and the third - sixth detailed operation in response to the common logic signal LOGS received from the third - first main detailed arithmetic logic circuit, the third - fifth main detailed arithmetic logic circuit, and the third - sixth main detailed arithmetic logic circuit.
[0111] For example, if the third - second detailed operation and the third - third detailed operation are common operations, the third - second main detailed arithmetic logic circuit, the third - third main detailed arithmetic logic circuit, the first - third - second slave detailed arithmetic logic circuit, and the first - third - third slave detailed arithmetic logic circuit can be the common logic circuit CLOG. The third - second main detailed arithmetic logic circuit and the third - third main detailed arithmetic logic circuit can generate a common logic signal LOGS. The first - third - second slave detailed arithmetic logic circuit and the first - third - third slave detailed arithmetic logic circuit may not generate the common logic signal LOGS.
[0112] The first slave panel driver 110B can perform the third - second detailed operation and the third - third detailed operation in response to the common logic signal LOGS received from the third - second main detailed arithmetic logic circuit and the third - third main detailed arithmetic logic circuit.
[0113] In this embodiment, the common logic circuit CLOG included in the first slave driving circuit SIP may not generate the common logic signal LOGS. The first slave panel driver 110B can perform the common operation in response to the common logic signal LOGS received from the main panel driver 110A. Therefore, the power consumption of the display device can be reduced. In addition, the first slave driving circuit SIP may not generate the common logic signal LOGS, so that the first slave driving circuit SIP may not include a circuit for generating the common logic signal LOGS. Therefore, the size of the first slave driving controller 200B can be reduced. In addition, the integration of the display device can be improved.
[0114] In an embodiment, the common logic circuit CLOG can be changed. In an embodiment, the common logic circuit CLOG can be changed in real time in response to an input control signal CONT.

[0117] In this embodiment, the second slave panel driver 110C can receive the common logic signal LOGS. The common logic signal LOGS can be a signal that enables the main panel driver 110A, the first slave panel driver 110B, and the second slave panel driver 110C to perform a common operation.
[0118] In this embodiment, the second slave panel driver 110C may include a common logic circuit and a second slave detailed operation logic circuit. For example, the second slave detailed operation logic circuit may be a circuit that generates a signal (e.g., a second slave detailed logic signal) that causes the main panel driver 110A and the second slave panel driver 110C to perform different operations from each other. For example, the different operations may be operations of changing the driving frequency.
[0119] In this embodiment, the first slave panel driver 110B and the second slave panel driver 110C may not generate a common logic signal LOGS. Therefore, the power consumption of the display device can be further reduced.

The common operation of the main panel driver 110A and the second slave panel driver 110C may be referred to as a second common operation.
[0125] In addition, the first common operation and the second common operation may be different, such that the number of first slave common logic signals LOGS1 and the number of second slave common logic signals LOGS2 may be different. Accordingly, the power consumption of the display device can be controlled more effectively.
[0126] In the present embodiment, the second slave panel driver 110C may include a second slave driving controller, and the second slave driving controller may include a second-first slave driving circuit configured to output a signal for performing the first driving operation described above.
