[ first embodiment ] A method for manufacturing a semiconductor device
As shown in fig. 1, an embodiment of the present invention provides a display control method for a display screen, including the following steps:
s10, receiving and storing the first area image data corresponding to the driving chip;
s30, detecting first target area image data in the first area image data to obtain a first detection result;
s50, generating first configuration information of a register of the driving chip according to the first detection result;
s70, configuring the register according to the first configuration information to control the display of the display screen.
The display control method of the display screen provided by the embodiment is applied to a driving chip of the display screen, and in order to facilitate a clearer understanding of the embodiment, the display control method of the display screen of the embodiment is described in detail below.
Specifically, the display screen may include a plurality of driving chips, for example, one driving chip is used here, the driving chip may drive 16 × 8 LED dot matrixes, for example, the driving chip is responsible for 8 sweeps, that is, 8 rows of the LED dot matrixes, and the driving chip is responsible for 16 channels, that is, 16 columns of the LED dot matrixes. The driver chip 210 can support scan and 16 data channels control, and can be a row-column-in-one driver chip.
In the above, the driver chip receives and stores the first area image data corresponding to the driver chip, where the first area image data is the image data of the area corresponding to the driver chip in the image data that needs to be displayed on the display screen, and the first area image data is only for distinguishing names and does not indicate a sequence. Then, the driving chip detects first target area image data in the first area image data to obtain a first detection result, where the first target area image data is target data in the first area image data, and the target data may be, for example, the first area image data, that is, all image data for which the driving chip is responsible, or may also be, for example, one row of image data in the first area image data, or may also be, for example, image data of each column of a certain row in the first area image data, and of course, the embodiment of the present invention is not limited thereto. Then, the driving chip generates first configuration information of a register of the driving chip according to the first detection result, and the register is configured according to the first configuration information so as to control the display of the display screen.
Specifically, if it is detected that all first target area image data corresponding to all sweeps in charge of the driver chip, that is, the first area image data in charge of the driver chip, are zero, the first target area image data corresponding to all sweeps in charge of the driver chip may specifically be, for example, the first target area image data corresponding to the LED dot matrix in charge of the driver chip, that is, when an image corresponding to the first target area image data is completely black, the first detection result is stored; when third target area image data, such as next frame area image data, is received and stored, first configuration information of a register of the driver chip is generated according to that the first detection result, i.e., the first target area image data, is zero, the first configuration information, for example, current gain coefficients of all sweeps are set to be zero, wherein the third is only named for distinction. Specifically, the current gain coefficient of the driver chip may be, for example, a global current gain coefficient of a register of the driver chip, and is adjusted for all swept output currents; for example, the different current gain coefficients of the driver chip for three colors (R, G, B) can be used, which is only an example and the invention is not limited thereto. And the driving chip configures the register according to the first configuration information so as to set all scanned current gain coefficients corresponding to the driving chip to be zero, thereby achieving the purpose of saving power consumption of the display screen.
When it is detected that all the third target area image data corresponding to the scan in the second area image data is not zero, the register of the driving chip is reconfigured, and the initial value of the current gain coefficient is reconfigured to the register of the driving chip, so that the driving chip is turned on again for display. The specific detection and configuration process is the same as the step when the image data of the target area is zero, and the configuration information is changed into the current gain coefficients of all the sweeps to be set as initial values.
In a specific implementation manner of the embodiment of the present invention, the first target area image data may be image data corresponding to a first target scan of the driving chip; accordingly, the first configuration information may be a current gain factor of the first target sweep. That is, the image data for each scan of the driving chip (that is, the image data corresponding to each row of the LED dot matrix) is configured once when detecting the image data for the next scan. When detecting that all image data corresponding to the target scan are zero, configuring a current gain coefficient of the target scan of the register of the driving chip to be zero, where the current gain coefficient may be, for example, a global current gain coefficient of the target scan of the register of the driving chip; and when the image data corresponding to the target scan is not completely zero, configuring the current gain coefficient of the target scan of the register of the driving chip as an initial value. Thus, the configuration of the register of the driving chip is carried out once every scanning, and the control mode is more precise and flexible while the power consumption of the display screen is reduced.
In a specific implementation manner of the embodiment of the present invention, the first target area image data may be image data corresponding to a first target channel of a second target scan of the driving chip, and may be, for example, a certain channel of a certain scan, where the first and second are only distinguished names, and are not limited in sequence; accordingly, the first configuration information may be channel switch information of the first target channel of the second target sweep. That is, image data (that is, image data corresponding to each LED dot in each row of the LED dot matrix) in charge of each channel of each scan of the driving chip is configured once when detecting image data in charge of a next target channel. When detecting that image data corresponding to a target channel of the target scanning is zero, configuring the target channel of a register of the driving chip to be in a closed state; and when detecting that the image data corresponding to the target scanning is not zero, configuring a target channel of a register of the driving chip to be in an open state. Therefore, as long as the scanning data of the current output channel is all zero, the corresponding channel current can be closed, and the purpose of reducing the power consumption of the driving chip is achieved.
In summary, in the display screen display control method provided in this embodiment, the driving chip detects the first target area image data in the first area image data to obtain a first detection result, then configures and generates the first configuration information of the register of the driving chip according to the first detection result, configures and displays the register according to the first configuration information, and implements a purpose of dynamically saving energy for the display screen by finely controlling the driving chip, thereby reducing power consumption of the display screen.
[ second embodiment ]
Referring to fig. 2, a second embodiment of the present invention provides a display control method for a display screen, including the steps of:
s20, receiving and storing the first image data;
s40, detecting second target area image data in the first image data to obtain a second detection result;
s60, generating second configuration information of a register of a target driving chip of a display screen for displaying the second target area image data according to the second detection result;
and S80, sending the second configuration information and a configuration command to the target driver chip, where the configuration command is used to instruct the target driver chip to configure the register according to the second configuration information, so as to control the display of the display screen.
The display control method of the present embodiment can be applied to the receiving card 100 shown in fig. 3, for example, and for facilitating a clearer understanding of the present embodiment, the display control method of the present embodiment is described in detail below with reference to fig. 3.
Specifically, referring to fig. 3, the display screen 200 includes a plurality of driving chips 210 (only 2 are shown as schematic diagrams), the driving chips 210 may drive, for example, 16 × 8 LED dot matrixes, for example, the driving chips 210 are responsible for 8 sweeps, that is, 8 rows of the LED dot matrixes, and the driving chips 210 are responsible for 16 channels, that is, 16 columns of the LED dot matrixes. The driver chip 210 can support scan and 16 data channels control, and can be a row-column-in-one driver chip. The receiving card 100 may, for example, connect a plurality of driving chips 210 to control the driving chips 210, and specifically, the receiving card 100 may, for example, connect a first driving chip 210 of the plurality of driving chips 210 through a data transmission channel, the plurality of driving chips 210 are cascaded, and the receiving card 100 connects each driving chip 210 through a command transmission channel to send a command.
As mentioned above, the receiving card 100 receives first image data, for example, first frame image data, and buffers the first image data in a memory of the receiving card 100, where the memory may be, for example, a Synchronous Dynamic Random Access Memory (SDRAM), and then detects a second target area image in the first image data to obtain a second detection result, where the second target area image is image data corresponding to a certain driver chip in the first image data, and generates second configuration information of a register of a target driver chip of a display screen for displaying the second target area image data according to the second detection result. Specifically, if it is detected that the first target area image data corresponding to all sweeps in charge of a certain driving chip in the first image data is zero, the first target area image data corresponding to all sweeps in charge of a certain driving chip may specifically be, for example, the first target area image data corresponding to the LED dot matrix in charge of a certain driving chip, that is, when the image corresponding to the first target area image data is completely black, the second detection result is stored; when receiving and storing second image data, for example, second frame image data, second configuration information of a register of the target driver chip is generated according to that the second detection result, that is, the second target area image data, is zero, and the second configuration information, for example, current gain coefficients of all sweeps are set to be zero, specifically, the current gain coefficient of the driver chip may be, for example, a global current gain coefficient of the register of the driver chip, and the current gain coefficient is adjusted for output currents of all channels; for example, the different current gain coefficients of the driver chip for three colors (R, G, B) can be used, which is only an example and the invention is not limited thereto. The receiving card 100 may first send the second configuration information of the register to the driving chip 210 through the data transmission channel, for example, and then send the configuration command to the driving chip 210 through the command transmission channel, where the configuration command may represent a different configuration command through a combination of DCLK and LE signals, for example, the rising edge of two DCLK in the LE signal packet represents the image data latch, and the rising edge of three DCLK in the LE signal packet represents the configuration of the first set of driving chip registers. The driver chip 210 configures the register according to the configuration instruction and the second configuration information to set all swept current gain coefficients corresponding to the driver chip 210 to be zero, thereby achieving the purpose of saving power consumption of the display screen.
As described above, the receiving card 100 continuously detects the second image data, for example, the second frame image data, and when it is detected that all the scanning image data corresponding to all the channels in the second image data are not zero, reconfigures the register of the driving chip, and reconfigures the initial value of the current gain coefficient to the register of the driving chip, so that the driving chip is turned on again for display. The specific detection and configuration process is the same as the step when the image data of the target area is zero, and the configuration information is changed into the current gain coefficients of all the sweeps to be set as initial values.
In a specific implementation manner of the embodiment of the present invention, the second target area image data may be image data corresponding to the first target scan of the target driver chip; accordingly, the second configuration information may be a current gain factor of the first target sweep. That is, the receiving card detects image data (i.e., image data corresponding to each row of the LED dot matrix) in each scan of one of the driving chips in the first image data, and performs configuration of the register of the driving chip once when detecting image data in the next scan. When detecting that all image data corresponding to the target scan are zero, configuring a current gain coefficient of the target scan of the register of the driving chip to be zero, where the current gain coefficient may be, for example, a global current gain coefficient of the target scan of the register of the driving chip; and when the image data corresponding to the target scan is not completely zero, configuring the current gain coefficient of the target scan of the register of the driving chip as an initial value. Thus, the configuration of the register of the driving chip is carried out once every scanning, and the control mode is more precise and flexible while the power consumption of the display screen is reduced.
In a specific implementation manner of the embodiment of the present invention, the second target area image data may be image data corresponding to a first target channel of a second target scan of the target driver chip, and may be, for example, a certain channel of a certain scan, where the first and second are only distinguished names, and are not limited in order; accordingly, the second configuration information may be channel switch information of the first target channel of the second target sweep. That is, the receiving card detects the image data (that is, each column in each row of the LED dot matrix, that is, the image data corresponding to each LED dot) in each channel of one scanning of a certain driving chip in the first image data, and performs the configuration of the register of the driving chip once when detecting the image data in charge of the next target channel. When detecting that image data corresponding to a target channel of the target scanning is zero, configuring the target channel of a register of the driving chip to be in a closed state; and when detecting that the image data corresponding to the target scanning is not zero, configuring a target channel of a register of the driving chip to be in an open state. Therefore, as long as the scanning data of the current output channel is all zero, the corresponding channel current can be closed, and the purpose of reducing the power consumption of the driving chip is achieved.
In summary, in the display control method for the display screen provided in this embodiment, a second detection result is obtained by detecting second target area image data in the first image data, then second configuration information of a register of a target driver chip of the display screen that displays the second target area image data is generated according to the second detection result, and the second configuration information and a configuration command are sent to the target driver chip to configure the register, so that the purpose of performing dynamic energy saving on the display screen is achieved, and the power consumption of the display screen is reduced.
