Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection of the present invention.
A control method, apparatus, electronic device, and storage medium of a display screen of the present invention are described below with reference to fig. 1 to 5.
Specifically, the present invention provides a control method of a display screen, and referring to fig. 1, fig. 1 is one of the flow diagrams of the control method of the display screen provided by the present invention.
The control method of the display screen provided by the embodiment of the invention comprises the following steps:
it should be noted that the execution main body of the display screen control method provided in the embodiment of the present invention may be a server or a computer device, such as a mobile phone, a tablet computer, a notebook computer, a palm top computer, a vehicle-mounted electronic device, a wearable device, an ultra-mobile personal computer (UMPC), a netbook, or a Personal Digital Assistant (PDA).
In the embodiment of the present invention, a notebook computer is taken as an example for analysis, and a camera module of the notebook computer needs to select a camera module with eyeball tracking and a positioning light module. When the notebook computer is started to operate, eyeball movement data of the detected object on the display screen is collected through the camera module and the positioning light module, and then the fixation position is determined based on the eyeball movement data.
it should be noted that the display screen, the CPU, and the GPU are three parts of the notebook system with the largest power consumption, and especially in a low-load office environment, the power consumption of the display screen may account for 40% to 50% of the overall power consumption of the notebook, so that reducing the power consumption of the display screen may greatly improve the battery life of the notebook. Based on this, in order to reduce the display power consumption of the display screen, the embodiment of the invention adopts a region division mode to enable each region to display different brightness information, thereby reducing the display power consumption of the display screen.
After the gaze position is determined, a plurality of first regions are determined based on the gaze position, and then luminance information for each first region is determined.
And step 300, adjusting the brightness of the display screen according to the brightness information of each first area.
It should be noted that the embodiment of the present invention adopts an OLED Display, and an Organic Light Emitting Display (OLED) refers to a phenomenon that an Organic semiconductor material and a Light Emitting material emit Light by carrier injection and recombination under the driving of an electric field, and the principle thereof is as follows: the ITO transparent electrode and the metal electrode are respectively used as an anode and a cathode of the device, under the drive of set voltage, electrons and holes are respectively injected into the electron and hole transport layers from the cathode and the anode, the electrons and the holes respectively migrate to the luminescent layer through the electron and hole transport layers and meet in the luminescent layer to form excitons and excite luminescent molecules, and the latter emits visible light through radiation relaxation.
In the light source of the conventional LCD display technology, the liquid crystal layer only serves as a light switch and cannot adjust the light source, whereas the light source of the OLED display technology according to the embodiment of the present invention is an organic light source excited by each individual electrode and can adjust the light source at a pixel level. Based on this, the luminance information of the different first regions can be adjusted.
After determining the brightness information of each first area, adjusting the brightness of the OLED display screen according to the brightness information of each first area, for example, assuming that the first area includes an area a, an area B and an area C, where the brightness information of the area a is 90% -100%, the brightness information of the area B is 70% -80% and the brightness information of the area C is 50% -60%, adjusting the area a, the area B and the area C to the corresponding brightness.
According to the control method of the display screen, the gazing position is determined; determining a plurality of first areas according to the watching positions, and determining the brightness information of each first area; and adjusting the brightness of the display screen according to the brightness information of each first area. According to the embodiment of the invention, the eyeball tracking technology and the OLED display technology are combined, the display screen is divided into the areas based on the eyeball tracking technology, and the brightness information of each area of the display screen is adjusted through the OLED display technology, so that the display power consumption of the display screen is reduced, and the endurance time of the equipment is prolonged.
Based on the above embodiment, the determining a plurality of first regions according to the gaze location includes: and taking the watching position as a center, and carrying out region division on the display screen based on different preset distances to obtain a plurality of first regions.
After the fixation position is determined, the fixation position is used as a center, and the display screen is subjected to region division to obtain a plurality of first regions based on different preset distances, wherein the first regions can be in the shapes of a circle, an ellipse, a square and the like, and therefore the preset distances can include preset radiuses, preset lengths, preset widths and the like. For example, referring to fig. 2, it is assumed that the gaze position is B0, a circular area where B0-B1 are located is defined as an area a, an area where B1-B2 are located is defined as an area B, an area where B2-B3 are located is defined as an area C, and an area larger than B3 is defined as an area D, where the radius may be determined as needed, and is not limited herein.
According to the embodiment of the invention, the region division is carried out on the display screen by taking the watching position as the center and based on different preset distances to obtain a plurality of first regions, and based on the first regions, the partition management of the display screen is realized.
Based on the above embodiment, the determining the brightness information of each of the first regions includes:
determining distance information between each of the first regions and the gaze location; and determining the brightness information of each first area according to the distance information.
After dividing the first regions, determining distance information between each first region and the gaze location, and then determining brightness information of each first region according to the distance information, for example, referring to fig. 2, the distance relationship between each first region and the gaze location B0 is: the area a < the area B < the area C < the area D, wherein the closer the distance, the greater the luminance, the luminance information of each first area may be set as: 90% -100% of area A, 70% -80% of area B, 50% -60% of area C and less than 40% of area D.
According to the embodiment of the invention, the brightness information of each first area is determined through the distance information between each first area and the watching position, so that the accuracy and the efficiency of determining the brightness information are improved.
Based on the above embodiment, before determining the gaze location, the method includes: determining the size information of the display screen and the data processing information of the CPU; and carrying out area division on the display screen according to the size information of the display screen and the data processing information of the CPU to obtain a plurality of second areas.
It should be noted that, in order to improve the adjustment efficiency of the brightness information of the display screen, partition management needs to be performed on the display screen in advance.
After the notebook computer is started to operate, the size information of the display screen and the data processing information (such as the processing capacity of the CPU) of the CPU are determined, and then the display screen is subjected to area division based on the size information of the display screen and the data processing information of the CPU to obtain a plurality of second areas. Wherein, the more the number of the second region partitions, the stronger the requirement on the processing capacity of the CPU.
For example, referring to fig. 2, the screen area division may divide the display screen into a plurality of squares, such as 6 × 6,8 × 8, 10 × 10, 12 × 12, etc., each square representing a second area, according to the screen size and CPU processing power. Based on this, after dividing the second area, the brightness information of the display screen can be adjusted based on the second area, thereby improving the adjustment efficiency of the brightness information of the display screen.
According to the embodiment of the invention, the display screen is subjected to area division by adopting the size information of the display screen and the CPU processing capacity to obtain the plurality of second areas, so that partition management of the display screen is realized, and the adjustment efficiency of the brightness information of the display screen is improved.
Based on the above embodiment, the adjusting the brightness of the display screen according to the brightness information of each of the first areas includes: determining an overlapping area of each first area and each second area; determining brightness information of each overlapping area according to the brightness information of each first area; and adjusting the brightness of the display screen according to the brightness information of each overlapping area.
In order to improve the adjustment efficiency of the brightness information of the display screen, the overlapping area of each first area and each second area can be predetermined, then the brightness information of each overlapping area is determined according to the brightness information of each first area, and then the brightness of the display screen is adjusted according to the brightness information of each overlapping area. For example, referring to fig. 2, the second areas, that is, the covered squares, where the area a, the area B, the area C, and the area D are respectively determined, where a number or coordinate information is set for each square in advance, so that when the brightness information of the display screen is adjusted, the brightness information of the display screen can be quickly positioned directly based on the number or coordinate information of each square, thereby realizing quick adjustment of the brightness information of the display screen. For example, if the second area covered by the area a is the square 1 and the square 2, and the brightness information of the area a is 90% -100%, when the brightness information of the display screen is adjusted, the second area is directly positioned to the square 1 and the square 2, and the brightness information of the square 1 and the square 2 is adjusted to be 90% -100%, so that the adjustment of the brightness information of the display screen can be quickly realized through the pre-divided squares, thereby improving the adjustment efficiency of the brightness information of the display screen, further reducing the display power consumption of the display screen, and improving the duration of the device.
Based on the above embodiment, the adjusting the brightness of the display screen according to the brightness information of each of the overlapping areas includes: determining a pulse width modulation signal of each overlapping area according to the brightness information of each overlapping area; and adjusting the brightness of the display screen according to the pulse width modulation signal of each overlapping area.
It should be noted that the duty ratio of PWM (Pulse width modulation) represents the average voltage, and the average voltage at both ends of the OLED and the current limiting resistor changes after the duty ratio changes, so the current flowing through the OLED also changes, and therefore, the brightness of the display screen of the notebook computer can be adjusted by the PWM duty ratio.
Specifically, a pulse width modulation signal for each overlap region is determined according to the brightness information of each overlap region, and then the brightness of the display screen is adjusted according to the pulse width modulation signal for each overlap region. For example, the corresponding relation between the duty ratio of the PWM controller and the physical brightness of the OLED display screen is preset, wherein the output pulse wave of the PWM controller is digital output, the amplitude of the output pulse wave includes high level "1" and low level "0", if a pulse with a period T is to be generated, the output end of the PWM controller can be controlled to output "1" by using a programmed instruction of a single chip, and the pulse wave is kept for a period Tp, and then output low level "0", and the pulse wave is also kept for a period Tr to complete a pulse wave with a period T, and the PWM pulse wave is capable of adjusting the duty ratio. The duty ratio is the proportion of the positive half-cycle pulse width in the whole period, namely the ratio Tp/T100% of the high-level holding time in the period, T is the pulse period, the ratio is a percentage, therefore, under the condition of a certain period, the adjustment of the duty ratio is the time for adjusting the high-level holding. The maximum value of the physical brightness of the display screen may be corresponding to the duty ratio of 100%, the minimum value of the physical brightness of the display screen may be corresponding to the duty ratio of 0%, and the correspondence between the physical brightness and the duty ratio is calculated by using a piecewise fitting method.
After the corresponding relation between the duty ratio of the PWM controller and the physical brightness of the OLED display screen is determined, an adjusting signal of an input signal end and the current duty ratio are obtained, and the duty ratio output by the PWM controller is compared, judged and set according to the adjusting signal; the adjustment signal at the input signal side is a luminance adjustment signal determined based on luminance information of each overlapping area. The output PWM duty ratio is realized by setting a PWM period register and a PWM comparison register, and the PWM duty ratio = PWM comparison register/PWM period register.
And after the duty ratio output by the PWM controller, generating a PWM signal of the corresponding OLED display screen physical brightness by the PWM signal generator according to the duty ratio, and then adjusting the brightness of the backlight OLED lamp of the display screen by the OLED power supply driver according to the PWM signal.
According to the embodiment of the invention, the pulse width modulation signal of each overlapping area is determined according to the brightness information of each overlapping area, and then the brightness of the display screen is adjusted according to the pulse width modulation signal of each overlapping area, so that the display power consumption of the display screen is reduced, and the endurance time of the equipment is prolonged.
Based on the above embodiment, the determining the gaze location includes: acquiring eyeball movement data of a detected object on the display screen; and determining the fixation position according to the eyeball movement data.
The camera module and the positioning light module for eyeball tracking are adopted to track the corresponding eyeball to be detected, for example, the eyeball and the characteristic change around the eyeball are tracked, or the iris angle change is tracked, or light beams such as infrared rays and the like are actively projected to the iris to extract the characteristics for tracking. In the process of tracking the eyeball, eyeball movement data of the eyeball watched on the display screen is tracked and recorded, for example, the movement track and the stop position of the eyeball are tracked and recorded, wherein the movement track and the coordinate position range are set in the range of the display screen in the eyeball watching equipment, and then the watching position is determined according to the movement track and the stop position of the eyeball.
According to the embodiment of the invention, the gaze position is determined through the eyeball movement data, so that the gaze position can be rapidly determined and the accuracy of determining the gaze position is improved.

After the notebook computer is started, size information of the display screen and the processing capacity of the CPU are acquired, and then the display screen is divided into areas based on the size information of the display screen and the data processing information of the CPU, for example, the screen area is divided into 8 × 8 checkerboards. Eyeball movement data of the detected object on the display screen are collected through an eyeball tracking technology, a fixation position is determined based on the eyeball movement data, and the eyeball movement data are transmitted to a CPU for processing.
3. The CPU transmits the received eyeball movement data to the GPU, the fixation position is used as the center, the display screen is divided into a plurality of first areas based on different preset distances, for example, the fixation position is B0, the first circle on the periphery is B1, the second circle on the periphery is B2, and the like. Meanwhile, the CPU can define the brightness range of different areas, for example, the brightness information of B0-B1 is 90% -100%, the brightness information of B1-B2 is 70% -80%, the brightness information of B2-B3 is 50% -60%, and the brightness information of the area larger than B3 is 30% -40%.
4. And after receiving the instruction of the CPU, the GPU transmits the brightness information of the corresponding area to the control IC of the OLED display.
5. After receiving the instruction of the GPU, the control IC of the OLED display controls the brightness in the designated area in a PWM manner, for example, obtains a corresponding relationship between a duty ratio of the PWM controller and the physical brightness of the OLED display, then obtains an adjustment signal of the input signal terminal and a current duty ratio, compares and determines and sets the duty ratio output by the PWM controller according to the adjustment signal, further generates a PWM signal of the corresponding physical brightness of the OLED display according to the duty ratio by the PWM signal generator, and finally adjusts the brightness of the backlight OLED lamp of the display according to the PWM signal by the OLED power driver.
