Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, an embodiment of the present invention provides a display driving circuit, which includes a driving module 101 and at least two display units 102;
the driving module 101 comprises a display system interface 1011, a buffer memory 1012, a timing controller 1013 and a power controller 1014, and each display unit 102 comprises a respective gate driver 1021 and a source driver 1022;
the timing controller 1013 configured to receive an image display control signal, generate a target control signal according to the image display control signal, and output the target control signal to the display system interface 1011 and the buffer memory 1012;
the display system interface 1011 is configured to receive image data including at least two signal sources according to the target control signal, and output the received image data of the at least two signal sources to the buffer memory 1012;
the buffer memory 1012 is configured to output the received image data of each signal source to the source driver 1022 of the display unit 102 corresponding to the signal source according to the target control signal;
the power controller 1014 is configured to receive the image display control signal, generate a driving power and a driving control signal corresponding to each signal source according to the image display control signal, and output the driving power and the driving control signal to the gate driver 1021 and the source driver 1022 of the display unit 102 corresponding to each signal source.
In this embodiment, the different display units 102 may exist in different display screens, or may exist in the same display screen. The image display control signal may be a low level signal, a high level signal, a rising edge signal, or a falling edge signal. The target control signal may include a clock signal and a timing control signal, may be only a clock signal or a timing signal, and may be other control signals. The clock signal is generally used in a synchronous circuit, and the clock edge triggering means that the state change of a component controlled by the clock signal occurs at the time when the clock edge arrives. When the clock signal arrives, the related components change the output state according to the input signal, so that the related electronic components can synchronously operate. The data sent or received by the control component can be the rising edge of the clock signal or the falling edge of the clock signal.
In this embodiment, the image data of the at least two signal sources may be the same image data, but come from different signal sources; or the image data may be from different sources. The image data may be image data of a person, flower or grass, an animal, or landscape. The image data resolution of different signal sources can be the same or different. For example: the image data of the signal source I is 640 × 480 image data, and the image data of the signal source II is 640 × 480 image data; or the image data of the signal source I is 640 × 480 image data, and the image data of the signal source II is 1024 × 768 image data. Of course, the resolution may be other than the above resolution, and the embodiment of the present invention is not limited thereto.
In this embodiment, the display unit 102 corresponding to the signal source can be understood as such. For example: the display unit comprises a signal source I, a signal source II and a signal source III, and a display unit I, a display unit II and a display unit III, wherein the signal source I, the signal source II and the signal source III correspond to the display unit I, the display unit II and the display unit III one to one, namely the signal source corresponds to the display unit I, the signal source II corresponds to the display unit II, and the signal source III corresponds to the display unit III. Of course, in addition to this, a signal source may correspond to a plurality of display units, for example: the signal source I corresponds to the display unit I and the display unit II, the signal source II corresponds to the display unit III, and the signal source II corresponds to the display unit III.
In this embodiment, the driving control signals corresponding to the signal sources may also correspond to the corresponding relationships, and are not described herein again. The driving control signal is used to control the gate driver 1021 and the source driver 1022 of each display unit 102 so that they operate normally. The power controller may also provide driving power for the gate driver 1021 and the source driver 1022 of each display unit 102. The driving power source is understood to be a power source which converts a power supply into a specific voltage and current to drive the grid electrode or the source electrode to work, and generally, the input of the driving power source comprises high-voltage power-frequency alternating current, low-voltage direct current, high-voltage direct current, low-voltage high-frequency alternating current or the like.
In the embodiment of the invention, at least two display units 102 are controlled by one driving module 101, so that each display unit 102 does not need to be provided with one driving module 101, and the manufacturing cost of a display driving circuit is saved. The driving module 101 shared by each display unit 102 is independent, so that the size of a single display screen can be effectively reduced, and the competitiveness of the size of the whole mobile terminal can be improved. When there are a plurality of display units 102, the cost of the driving module 101 of a single display unit 102 can be significantly reduced, and only one driving module 101 is needed to control all the display units 102. In this control scheme, the flexibility and scalability of the display driver circuit is increased, and theoretically, the display driver circuit can be extended to an unlimited number of display units 102 as long as the performance of the main processor allows.
Optionally, the display system interface 1011 is configured to receive image data including at least two signal sources through a multi-interface input circuit according to the target control signal, and output the received image data of the at least two signal sources to the buffer memory 1012 through a multi-interface output circuit.
In this embodiment, the multi-interface input circuit may be a single-interface input circuit for each signal source, for example, when there are three signal sources, a three-interface input circuit is used, and when there are four signal sources, four interfaces are used to connect the input circuit. Of course, a certain path of interface input circuit may transmit signals of multiple signal sources, for example, there are four signal sources, but there are only three paths of interface input circuits, and at this time, there may be a path of interface input circuit to transmit signals of two signal sources, which is also possible in this way.
Optionally, as shown in fig. 2, the driving module 101 further includes an image merger 1015, where the display system interface 1011 is configured to receive, according to the target control signal, image merging data sent by the image merger 1015 through an interface input circuit, where the image merging data includes image data of at least two signal sources, and output the image merging data to the buffer memory 1012;
the buffer memory 1012 is further configured to split the received image combination data into image data of each signal source, and output the image data of each signal source to the source driver 1022 of the display unit 102 corresponding to the signal source according to the target control signal.
In this embodiment, the image merger 1015 may be understood as a device that merges a plurality of images into one image. For example, two 1920 × 1080 images may be merged into 1920 × 2160 image or 3840 × 1080 image. If the two images are different in size, simple splicing can be performed, and only one image can be synthesized. Therefore, when a plurality of images are spliced, the image merging data can be output through one interface output circuit, and the data of each image does not need to be output by a plurality of interface output circuits, so that the manufacturing cost of the circuit is saved.
In this embodiment, the image splitting may be splitting the merged image by using the reserved identifier, or splitting the merged image after receiving a certain splitting signal, or splitting the merged image by using an automatic image recognition method to recognize the splitting of two different images, which is not limited in the embodiment of the present invention.
Optionally, the buffer memory 1012 is configured to shift and latch image data corresponding to each signal source, and output the image data to the source driver 1022 of the display unit 102 corresponding to each signal source according to the target control signal.
In this embodiment, through shifting and latching, a plurality of frames of image signals may be buffered in the buffer memory 1012, where the plurality of frames of image signals may include an image signal of one display unit 102, or may include image signals of a plurality of display units 102, and the image signals are output to the corresponding display units 102 when triggered by a target control signal, so that synchronization is maintained.
The display driving circuit of the embodiment of the invention comprises a driving module 101 and at least two display units 102; the driving module 101 comprises a display system interface 1011, a buffer memory 1012, a timing controller 1013 and a power controller 1014, and each display unit 102 comprises a respective gate driver 1021 and a source driver 1022; the timing controller 1013 configured to receive an image display control signal, generate a target control signal according to the image display control signal, and output the target control signal to the display system interface 1011 and the buffer memory 1012; the display system interface 1011 is configured to receive image data including at least two signal sources according to the target control signal, and output the received image data of the at least two signal sources to the buffer memory 1012; the buffer memory 1012 is configured to output the received image data of each signal source to the source driver 1022 of the display unit 102 corresponding to the signal source according to the target control signal; the power controller 1014 is configured to receive the image display control signal, generate a driving power and a driving control signal corresponding to each signal source according to the image display control signal, and output the driving power and the driving control signal to the gate driver 1021 and the source driver 1022 of the display unit 102 corresponding to each signal source. Thus, at least two display units 102 are controlled by one driving module 101, so that a driving module 101 is not required to be arranged for each display unit 102, and the manufacturing cost of a display driving circuit is saved.
In the prior art, each display unit 102 must have its own independent driving module 101, two driving modules 101 are required for two display units 102, three display modules are required for three display units 102, and N display modules are required for N display units 102. In the display driving circuit according to the embodiment of the present invention, the driving modules 101 of the plurality of display units 102 are independently shared by each display unit 102, only the source driver 1022 and the gate driver 1021 which cannot be shared are disposed in each display unit 102, the display system interface 1011, the buffer memory 1012, the timing controller 1013 and the power controller 1014 which can be shared are independently separated into a set of shared driving modules 101, and each display unit 102 is further added to form a complete display driving circuit. The use of a common driver module 101 to control multiple display elements 102 saves the overhead of driving the display circuitry and also increases the flexibility and scalability of the circuitry.
In addition, the display driving circuit may further include an image processor, which may process data to be displayed by the plurality of display units 102, and output image data and a clock signal, which may be transmitted through a single data and clock interface and displayed by the plurality of display units 102, where the clock signal may also ensure synchronization of the image data of the plurality of display units 102. In cooperation with the power controller 1014, it is possible to control the drive control signals and power supplies of the plurality of display units 102, so that image data is output to the corresponding display unit 102.
Of course, there may be an image merger 1015, and the image merger 1015 may merge the received image data, and may merge a plurality of images into one large image after merging. For example: the two 1920 × 1080 images may be merged into one 1920 × 2160 image, or may be merged into one 3840 × 1080 image. If there are 1024 x 768 and 640 x 480 images, one image can be synthesized by processing, but some processing is required. First, a blank image region of 1024 × 768 is generated on one side of the image of 1024 × 768, then the image of 640 × 480 is placed against the image of 1024 × 768, and finally the remaining blank region is removed, or of course, retained, so that two image data of different sizes are combined into one image data. If the original image has only one image, the image merging module can directly output the image to a circuit at the rear end without processing. The image data processed by the image merger 1015 is output to the display system interface 1011 through the display interface circuit, and then output to the buffer memory 1012 for buffering of the image data, and then the buffer outputs the image data to the source drivers of the plurality of corresponding display units 102, respectively. The timing controller 1013 receives the image display control signal and outputs the timing control signal to the display system interface 1011 and the buffer memory 1012, and completes the display in cooperation with each display unit 102. The images are merged and output, so that interface output circuits are saved, and image signals can be better synchronized.
