As shown in fig. 2, in an embodiment, a method for saving power of a display module is provided, and the embodiment is mainly illustrated by applying the method to the final display module in fig. 1. The method specifically comprises the following steps:
step S202, acquiring transmission data and determining the type of the transmission data.
In the embodiment of the invention, the transmitted data is acquired so as to determine the type of the transmitted data, and the process can be periodically carried out, so that the transmitted data stream is continuously monitored, and the method can be suitable for the change of the transmitted data in real time. In the embodiment of the invention, the data can be obtained in a transfer copying mode, which does not affect the normal transmission of the data, and the data sample can be obtained to analyze the type of the data.
And step S204, creating a corresponding bus protocol according to the type of the transmission data.
In the embodiment of the invention, according to different types of the transmitted data, a corresponding bus protocol is created for the transmission of the corresponding type of data. It should be noted that the bus protocol created by the present invention is created according to the type of the data to be transmitted, and the creation occurs during the normal transmission of the data, and for the purpose of additional creation, the purpose is to improve the transmission efficiency of the data of a specific type, and fully utilize the available bandwidth.
Step S206, determining whether the created bus protocol is greater than two, if so, reducing the resolution or frame rate of the display device or the film source.
In the embodiment of the invention, when the created bus protocols are more than two, the system judges that the data volume of the specific type needing to be transmitted is larger, and reduces the energy consumption of the system by reducing the resolution or the frame rate of the display equipment or reducing the resolution or the frame rate of the film source received by the system, thereby achieving the purpose of saving energy.
The energy-saving method for the display module, provided by the invention, has the advantages that the transmission data are acquired, the type of the transmission data is identified, the corresponding bus protocol is established according to different types of the transmission data, the corresponding type of data is transmitted by utilizing the established bus protocol, the transmission efficiency of the corresponding type of data can be improved, and the resource consumption caused by low speed is avoided; in addition, according to whether the created protocol is larger than two protocols or not, the resolution or the frame rate of the display device and the resolution or the frame rate of the film source are selectively reduced, so that resource waste caused by mismatching of the resolution or the frame rate of the display device and the film source is avoided, normal display of the display device is guaranteed, and meanwhile energy consumption of the display device is reduced.
In an embodiment, as shown in fig. 3, step S202, namely acquiring the transmission data and determining the type of the transmission data, may specifically include the following steps:
in step S302, data transmitted per unit time is acquired.
In the embodiment of the present invention, the unit time may be set to 1S, and in implementation, data acquisition may be performed every 1S, and data acquisition may also be performed every other set time, preferably every 1S, so as to monitor the change condition of data and adjust the created bus type in time, for example, close the created bus of the type, which is a further optimization scheme of the present invention.
Step S304, judging whether the number of the acquired data frames is greater than a set frame number threshold, if so, judging the type of the transmitted data is a video type.
In the embodiment of the present invention, for example, if the number of data frames acquired per second is greater than 24 frames, it may be determined as data of a video type.
Step S306, determining whether a row of pixels of the acquired data is greater than a set pixel threshold, if so, determining that the type of the transmitted data is a picture type, wherein the set pixel threshold is determined by multiplying the number of pixels in a row of the display device by a coefficient.
In the embodiment of the present invention, the set threshold may specifically be a physical pixel value corresponding to the display module, for example, a value of a row of pixels on the display screen or a value obtained by multiplying the value by a selected coefficient, such as 0.2, 0.5, 0.8, 1, and the like.
Step S308, determining whether the number of the acquired data is greater than the average number of commands in the unit time, and if so, determining that the type of the transmitted data is the control type.
In the embodiment of the invention, for the control class command, the quantity characteristic of the data is utilized by judging the quantity of the data and determining the average quantity of the commands in unit time. The invention adopts the number of the average commands in unit time as a standard, so that the corresponding bus type creation has higher pertinence, namely, the data bus is created only aiming at the condition of larger data volume, and the condition that the reverse side of the created data bus occupies more resources when the data volume is smaller is avoided.
In one embodiment, as shown in fig. 4, step S204, namely, creating a corresponding bus protocol according to the type of the transmission data, the body may include the following steps:
step S402, if the type of the transmitted data is control type, a control command serial bidirectional bus is established,
the control command serial bidirectional bus occupies two pins.
In the embodiment of the invention, a two-wire response confirmation mode is adopted, the unit time of the clock level with high and low levels is set to be 1ms, and when the unit time is larger than 8 pulses of a high-level clock, if the 9 th pulse is acquired to be high to low level, the triggering is carried out. The bus type is set to be a two-wire serial bus, and the maximum transmission bandwidth is determined according to twice of the number of the access devices.
Step S404, if the data type to be transmitted is a picture type, a picture serial bus is created, and the picture serial bus occupies three pins, including a differential level sending pin, a differential level receiving pin, and a differential ground receiving pin.
In the embodiment of the invention, the differential level transmitting pin is responsible for transmitting, the differential level receiving pin is responsible for receiving, and the differential ground wire receiving pin is responsible for referencing high level. The procedure of the transfer is illustrated: in the starting condition, the system sends the pin and receives the pin and is in the high level at the same time, send the pin and change from high low lasting 4 pulse levels, the system sets to send the level and output the data of 8 pictures (each row pixel 1024/8 of a picture), after the system receives the pin and finishes receiving 8 pixels, the system sets to receive the pin and is the low level, receive and finish.
Step S406, if the type of the transmitted data is a video type, a video serial bus is created, and the video serial bus occupies four pins, including a clock pin, a fast data input pin, a fast data output pin, and a multi-chip data selection pin.
In the embodiment of the invention, the system generates standard 8 high-low level data pulses and 9 th response pulse (the high-low opposite side has received the data pulse) in millisecond-level time.
In an embodiment, as shown in fig. 5, the reducing the resolution or the frame rate of the display device or the film source in step S206 may specifically include the following steps:
step S502, acquiring the physical resolution of the display device and the video resolution of the film source, and comparing the sizes of the two:
if the physical resolution is greater than the video resolution, reducing the physical resolution to adapt to the video resolution;
if the physical resolution is smaller than the video resolution, the video resolution is reduced to adapt to the physical resolution.
In the embodiment of the present invention, the first case: the physical resolution is greater than the film source resolution, for example, if the physical resolution is 4 times the film source resolution, the physical resolution is reduced to one fourth; in the second case: the physical resolution is less than the slice source resolution, e.g., the physical resolution is 0.25 times the slice source resolution, the slice source resolution is reduced by a factor of four. For example:
wli-fenbian (x1) =4096// pixel physical resolution 4096 x 2160
Pian-fenbian (x1) =1024// film source resolution 1024x768
Tes (x1) = Wli-fenbian (x 1)/peak-fenbian (x1) =4// lcm physical resolution is 4 times higher than the slice source resolution, and the reduction in physical resolution is a quarter.
Wli-fenbian (x1) =1024// physical resolution 1024x768
Pian-fenbian (x1) =4096// slice source resolution 4096 × 2160
Tes (x1) = Wli-fenbian (x 1)/peak-fenbian (x1) =0.25// physical resolution is 0.25 times the slice source resolution, reducing the slice source resolution by a factor of four.
The reduction of the film source resolution ratio can be realized through two modes, one mode is that a request is sent to cloud equipment, data with reduced resolution ratio are sent to a center console after resolution ratio reduction processing is carried out by a cloud, and then the data are displayed by a display module, the other mode is that data with unchanged resolution ratio are received, and the data are displayed by the display module after the resolution ratio reduction processing is carried out by the center console.
Step S504, acquiring the physical frame rate of the display device and the video frame rate of the film source, and comparing the sizes of the two:
if the physical frame rate is greater than the video frame rate, reducing the physical frame rate to adapt to the video frame rate;
and if the physical frame rate is less than the video frame rate, reducing the video frame rate to adapt to the physical frame rate.
In the embodiment of the present invention, the first case: the physical frame rate is greater than the slice source resolution, for example, if the physical frame rate is 4 times the slice source frame rate, the physical frame rate is reduced by one fourth. In the second case: the physical frame rate is smaller than the slice source resolution, for example, if the physical frame rate is 0.25 times the slice source frame rate, the slice source frame rate is reduced by one fourth. For example:
wli-frame (x1) =360hz// Hz physical frame rate 360
Pian-frame (x1) =60// Hz film source frame rate 60
Tes (x1) = Wli-frame (x 1)/Pian-frame (x1) =6// the physical frame rate is 6 times of the slice source frame, and the physical frame rate is reduced by one sixth.
Wli-frame (x1) =60// Hz physical frame rate 60
Pian-frame (x1) =360hz// Hz film source frame rate 360
Tes (x1) = Wli-frame (x 1)/pin-frame (x1) =1/6// the physical frame rate is 0.16 times the slice source frame, and the physical frame rate is reduced by one sixth.
The method for reducing the frame rate of the slice source may refer to the method for reducing the resolution, and the details of the present invention are not repeated herein.
As shown in fig. 6, in an embodiment, a display module energy saving device is provided, which can be integrated in the display module, and specifically includes:
