Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The terms first, second and the like in the description and in the claims, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type, and are not limited to the number of objects, such as the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The screen display calibration method provided by the embodiment of the application is described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.
Fig. 1 is a flowchart of a screen display calibration method according to an embodiment of the present application, where the screen display calibration method is applied to an electronic device.
As shown in fig. 1, the screen display calibration method includes:
step 101: and controlling a target screen of the electronic device to display a target calibration gray-scale image.
In the case of on-screen display calibration, the calibration is generally performed for display parameters at different gray levels, and therefore, at least one frame is required for displaying the calibrated gray-level image. Each frame of gray-scale image has a gray-scale color, namely, corresponds to a gray-scale level. The target calibration gray-scale image in this step is a frame of gray-scale image for displaying calibration, which corresponds to a gray-scale level. The more the number of gray-scale images used for display calibration is, the more comprehensive the display calibration can be performed, so that the display consistency is improved.
In addition, to avoid interference of the extraneous light source with the calibration of the screen display, the calibration environment needs to be a dark environment, such as an environment with an illumination intensity of less than or equal to 1 lux. In addition, when screen calibration is performed, it should be ensured that the target screen is free from breakage damage and clean and free from shielding.
Step 102: a first optical signal is received.
The first optical signal in this step is received by the photoelectric conversion panel provided at the first target sub-display area and is emitted from the second target sub-display area. The first target sub-display area and the second target sub-display area belong to the display area of the target screen, and the first target sub-display area and the second target sub-display area are arranged opposite to each other. For example, in the case where the target screen is a folding screen, the target screen may be brought into a folded state, and the first target sub-display area and the second target sub-display area are respectively located in two sub-screens which are provided opposite to each other on both sides of the folded position of the screen.
The photoelectric conversion panel disposed at the first target sub-display area is a hardware structure capable of receiving an optical signal and converting the received optical signal into an electrical signal, which may include, but is not limited to: transparent solar panels or light emitting diode panels made of tiny nanorods, etc. In addition, the photoelectric conversion panel can also convert the absorbed light energy into electric energy to charge an electric storage structure (such as a battery) of the electronic equipment.
Step 103: and determining a first parameter value of the target display parameter of the second target sub-display area according to the first optical signal.
From the foregoing, it can be seen that the photoelectric conversion panel disposed at the first target sub-display area can convert the received optical signal into an electrical signal, and after obtaining the electrical signal, the electronic device can analyze the electrical signal to determine the first parameter value of the target display parameter of the second target sub-display area.
Wherein, the target display parameters described herein include at least one display parameter, which may specifically include, but is not limited to: at least one of luminance, chromaticity, saturation, gamma (i.e., gamma), and color coordinates.
Wherein the first parameter values described herein include: at least one parameter value of the same target display parameter. Since the screen may have a problem of inconsistent display, different parameter values may be obtained according to the first optical signal for the same display parameter.
Step 104: a reference parameter value is determined based on the first parameter value.
In this step, a reference parameter value for each target display parameter at the target gray scale level is determined based on the first parameter value derived from the first optical signal. The target gray scale level is the gray scale level corresponding to the target calibration gray scale image.
Step 105: the parameter value of the target display parameter of the target display area of the target screen is set as the reference parameter value.
After determining the reference parameter value in step 104, the parameter value of the target display parameter of the target display area of the target screen under the target gray scale level may be set as the reference parameter value, so that the display effect of the target display area is consistent, and calibration of display consistency is achieved.
The target display area is the whole display area or part of the display area of the target screen. In the case where the target display area is a partial display area of the target screen, the position of the target display area may be set according to actual demands.
In the embodiment of the application, the electronic equipment performs display consistency calibration on the screen of the electronic equipment, so that the use of a professional calibration instrument can be omitted, and the calibration cost is saved. In addition, after the calibration function of the electronic equipment is started, the specific calibration process is automatically realized by the electronic equipment, so that the human interference is less, and the problem of calibration errors caused by misoperation generated manually can be reduced. In addition, in the process of using the electronic equipment, as the use times and the use time gradually increase, even if the electronic equipment is subjected to screen display consistency calibration before leaving the factory, the screen display consistency of the electronic equipment is gradually reduced. The screen display calibration method provided by the embodiment of the application can realize self calibration and does not need to have professional calibration knowledge, so that the function can be opened to a user, the user can automatically calibrate the display consistency of the screen in the using process of the electronic device, the display effect of the screen is improved, the using experience of the user is improved, and meanwhile, the screen display calibration is not limited to professional calibration before delivery.
Optionally, in the embodiment of the present application, the number of gray-scale images used for displaying calibration (hereinafter referred to as calibration gray-scale images) may be determined according to actual requirements, for example, the calibration effect and the time consumption may be comprehensively considered to determine, where the greater the number of calibration gray-scale images, the better the calibration effect, but the longer the time consumption; conversely, the smaller the number of calibration grayscale images, the worse the calibration effect, but the shorter the time-consuming.
In the case where the number of gray-scale images for display calibration (hereinafter referred to as calibration gray-scale images) is at least two frames, at the time of selecting the calibration gray-scale images, it is possible to realize at least the following three modes.
Mode one: for gray scale levels that can be displayed by the electronic device, such as 256 gray scales or 1024 gray scales, all corresponding gray scale images are used as calibration gray scale images.
Mode two: and (3) an equal interval method. The method has simple logic, and is concretely as follows: for the gray scale which can be displayed by the electronic equipment, a calibration gray scale can be determined every n gray scales, and a gray scale image corresponding to the calibration gray scale is used as a calibration gray scale image. Wherein n is an integer greater than or equal to 1, and the specific value can be set according to actual requirements, which is not limited in the embodiment of the present application.
Mode three: proportional method. This approach is logically more complex than the equidistant approach, specifically: the gray scale levels that can be displayed by the electronic device are divided into x groups, with the gray scale levels in each group being consecutive. Based on big data, counting the occurrence proportion of each group of gray levels when the user group uses the electronic equipment, and assuming that the required calibration gray level image is m frames, the number of gray level levels participating in calibration in each group of gray level is as follows: m times the ratio of the occurrence of the set of gray levels. After determining the number of gray-scale levels participating in the calibration in each group of gray-scale levels, an equal interval method may be employed to determine the gray-scale levels participating in the calibration in each group of gray-scale levels, and a gray-scale image corresponding to the gray-scale levels participating in the calibration may be taken as the calibration gray-scale image. Wherein x is an integer greater than 1, m is an integer greater than or equal to 2, and specific values of x and m can be set according to actual requirements, which is not limited in the embodiment of the application. In the case where the result obtained by multiplying m by the ratio of occurrence of each group of gray-scale levels is a non-integer, the result may be rounded or otherwise rounded. When the total number of the obtained gray scale levels participating in calibration is larger than m, discarding can be carried out according to actual requirements.
In the embodiment of the application, the calibration gray-scale image selected in advance through any one of the modes can be input into the electronic equipment, or the electronic equipment can generate the calibration gray-scale image through any one of the modes, for example, after the gray-scale level participating in the calibration is determined through any one of the modes, the corresponding calibration gray-scale image is generated according to the RGB (red, green and blue) ratio value of the gray-scale level participating in the calibration.
Alternatively, in the case where the number of calibration grayscale images is at least two frames, the target screen may display calibration grayscale images for each frame one by one in the screen display calibration process. The electronic device can determine whether to finish calibration according to whether the gray-scale image which does not participate in calibration is available.
Optionally, in the embodiment of the present application, in step 101: before the target calibration gray-scale image is displayed on the target screen of the control electronic device, the screen display calibration method may further include: a first input is received and, in response to the first input, an on-screen display calibration function is initiated.
The first input described herein may include, but is not limited to: at least one of touch operation (including touch operation to physical keys and touch operation to a touch screen), space gesture input operation, voice input operation, and fingerprint input operation. Of course, the foregoing starting manner is merely illustrative, and any other manner capable of implementing the starting of the calibration function of the screen display may be applied to the embodiment of the present application, which will not be described herein.
Alternatively, as can be seen from the foregoing, the on-screen calibration needs to be performed in a dark environment, where a professional calibrator can make a judgment by a professional light detection instrument when determining whether the current calibration environment meets the calibration requirements. When the user calibrates himself, the user can stretch out the hands, and whether the current calibration environment meets the calibration requirement is determined by taking the hands which cannot be seen obviously by eyes as a reference.
Of course, when a hardware structure (such as a photosensitive sensor) with an illumination intensity detection function is provided in the electronic device, the electronic device can also determine whether the current calibration environment meets the calibration requirement. For example, after the on-screen display calibration function is started, step 101: controlling a target screen of an electronic device to display a target calibration gray scale image may include: detecting the illumination intensity of the current environment; under the condition that the illumination intensity is detected to be smaller than or equal to the preset illumination intensity (such as 1 lux) (which indicates that the illumination condition of the current environment meets the calibration requirement), the target screen is controlled to display a target calibration gray-scale image, and the calibration process is started; under the condition that the illumination intensity is detected to be larger than the preset illumination intensity (the illumination condition of the environment before the explanation does not meet the calibration requirement), the calibration process is suspended, and a first prompt message can be generated and output so as to remind a calibrator (such as a professional calibrator or a user).
Optionally, since the calibration process requires power consumption of the electronic device, it is necessary to ensure that the electronic device has enough power to complete the calibration, step 101 follows the initiation of the on-screen calibration function: controlling a target screen of an electronic device to display a target calibration gray scale image may include: detecting a current electric quantity value, and if the current electric quantity value is larger than or equal to a preset electric quantity (the electric quantity of the electronic equipment is sufficient), controlling a target screen to display a target calibration gray-scale image, and starting a calibration process; under the condition that the current electric quantity value is smaller than the preset electric quantity (the electric quantity of the electronic equipment is insufficient to complete the calibration process), the calibration process is suspended, and a second prompt message can be generated and output to remind a calibrator (such as a professional calibrator or a user).
It should be noted that, when the electronic device determines whether the current calibration environment and the self-power meet the calibration requirement, neither of them may perform the calibration process.
Optionally, in an embodiment of the present application, the target screen includes at least one screen, that is: when the screen display calibration method provided by the embodiment of the application is implemented, the calibration operation can be performed on one screen, and the calibration operation can also be performed on a plurality of screens at the same time.
In the case that the target screen includes a screen, the target screen may be a flexible screen, that is, a curved and folded screen, so that the first target sub-display area and the second target sub-display area are disposed opposite to each other.
Wherein, in the case where the target screen includes at least two screens, the target screen may include at least one of a flexible screen and an inflexible screen (i.e., a screen that is inflexible to fold). For example, the target screen includes two inflexible screens, which are connected by a hinge and both of which can rotate about the hinge. When the included angle between the two screens is 180 degrees, the two screens are positioned on the same plane. When the screen display is calibrated, the included angle between the two screens can be adjusted to be smaller than or equal to a preset angle and larger than or equal to 0 degree. The preset angle is an angle smaller than 180 degrees, and the specific value can be obtained by setting a first target sub-display area and a second target sub-display area which are respectively positioned in the two screens as targets relatively.
Alternatively, the first target sub-display area and the second target sub-display area are sub-display areas set in advance, and when the sub-display areas are set, only the sub-display areas participating in the screen display calibration may be set in advance in the display areas of the target screen. For example, the target screen is a single screen, and two first target sub-display areas 201 and two second target sub-display areas 202 may be set in the display area 200 of the target screen in advance, as shown in fig. 2.
In addition to the foregoing setting manner, the display area of the target screen may be divided into at least two sub-display areas, and then the first target sub-display area and the second target sub-display area may be determined in the at least two sub-display areas. For example, the target screen is a screen, the display area 300 of the target screen may be divided into 16 sub-display areas 301 having equal sizes, and then two first target sub-display areas 302 and two second target sub-display areas 303 are set in the 16 sub-display areas 301, as shown in fig. 3. Wherein each smallest rectangle in fig. 3 is one sub-display area 301. For this setting, the number of first target sub-display areas and the number of second target sub-display areas are each at least one of the aforementioned at least two sub-display areas.
For the two setting modes, the number of the first target sub-display area and the second target sub-display area can be determined according to actual requirements, for example, the calibration effect and the time consumption of calibration can be comprehensively considered to be determined, and the more the number of the first target sub-display area and the second target sub-display area is, the better the calibration effect is, but the longer the time consumption is; conversely, the smaller the number of both, the worse the calibration effect, but the shorter the time-consuming. In addition, the first target sub-display area and the second target sub-display area may be the same or different in size and shape. When the number of the first target sub-display areas is at least two, the sizes and shapes of the first target sub-display areas may be the same or different; similarly, when the number of the second target sub-display areas is at least two, the sizes and shapes of the second target sub-display areas may be the same or different. However, for easier setting, the size and shape of the sub-display area involved in the calibration of the screen display are generally set to be the same.
Optionally, in the embodiment of the present application, the screen at the position of the first target sub-display area is attached to the screen at the position of the second target sub-display area, so that a part of the display areas in the target screen can receive the optical signal sent by another part of the display areas, and then the consistency of the screen display is calibrated based on the optical signal, so as to realize the self calibration of the electronic device to the screen of the electronic device, save the use of a professional calibration instrument, save the calibration cost, and the calibration process is simple and easy to operate, thereby being beneficial to improving the calibration efficiency.
For example, assume that the target screen is a flexible screen whose display area is divided into N sub-display areas of equal size in advance. As shown in fig. 4, when performing screen display calibration, a calibrator may fold the flexible screen 400 along the central axis 401 of the flexible screen 400, so that the first display areas 402 and the second display areas 403 on both sides of the central axis 401 are opposite to each other and are attached to each other. Further, it is assumed that the first display region 402 is provided with a first target sub-display region 4021, the second display region 403 is provided with a second target sub-display region 4031, the first target sub-display region 4021 and the second target sub-display region 4021 have the same size and shape, and when the first display region 402 and the second display region 403 are provided so as to face each other and are attached to each other, the first target sub-display region 4021 and the second target sub-display region 4021 overlap each other.
Optionally, in the embodiment of the present application, a spatial distance greater than 0 is provided between the screen at the position of the first target sub-display area and the screen at the position of the second target sub-display area. Wherein one first target sub-display area receives light signals emitted from at least two second target sub-display areas. The second target sub-display areas corresponding to the first target sub-display areas are respectively positioned in different directions of the first target sub-display areas.
Therefore, a part of display areas in the target screen can receive the optical signals sent by the other part of display areas, and then the screen display consistency is calibrated based on the optical signals, so that the self calibration of the electronic equipment to the screen is realized, the use of a professional calibration instrument is omitted, the calibration cost is saved, the calibration process is simple and easy to operate, and the calibration efficiency is improved. In addition, in this embodiment, the first target sub-display area may receive light signals in multiple directions, and like a human eye views each part of the screen at different angles, so that after the consistency calibration is performed on the screen based on the light signals received by the first target sub-display area, the display effect of the screen at different angles can be improved.
For example, assume that the target screen is a flexible screen whose display area is divided into N sub-display areas of equal size in advance. As shown in fig. 5, when performing screen display calibration, the calibration person may fold the flexible screen 500 inward to form a cylinder. It is further assumed that one first target sub-display area 501 and three second target sub-display areas 502 are set on the display area of the flexible screen 500, and that the first target sub-display area 501 receives light signals respectively emitted from the three second target sub-display areas 502 when the screen display is aligned.
When the screen display calibration is performed under the condition that a space distance larger than 0 exists between the screen at the position of the first target sub-display area and the screen at the position of the second target sub-display area, if the number of the first target sub-display areas is at least two, the second target sub-display areas corresponding to each first target sub-display area can be controlled to be on one by one. For example, the display device has a first target sub-display area a and a second target sub-display area B, where the first target sub-display area a corresponds to the second target sub-display areas C and D, and the second target sub-display area B corresponds to the second target sub-display areas E and F, when the screen display is calibrated, only the second target sub-display areas C and D may be controlled to be on, and the other display areas are in the off state. And then, controlling the second target sub-display areas E and F to lighten the screen, wherein other display areas are in a screen-off state so as to prevent the first target sub-display area from receiving the off signals transmitted by the display areas except the corresponding second target sub-display area and influencing the calibration.
Optionally, step 104: determining the reference parameter value from the first parameter value may include:
determining the target parameter value as a reference parameter value of the corresponding target display parameter when the number of target parameter values of the first parameter value corresponding to the same target display parameter is one; in the case where the number of target parameter values corresponding to the same target display parameter in the first parameter values is at least two, an average value of the target parameter values is determined as a reference parameter value of the corresponding target display parameter.
For example, the target display parameters include: the first parameter values include at least one luminance parameter value (corresponding to the target parameter value) and at least one chrominance parameter value (corresponding to the target parameter value). Taking the luminance parameter as an example, if the first parameter value includes a luminance parameter value, determining the luminance parameter value as a reference parameter value of the corresponding luminance parameter; if the first parameter value includes at least two brightness parameter values, calculating an average value of all brightness parameter values, and determining the average value as a reference parameter value of the corresponding brightness parameter. The principle of determining the reference parameter value of the chrominance parameter is the same as that of determining the reference parameter value of the luminance parameter, and will not be described herein.
Optionally, step 104: determining a reference parameter value from the first parameter value may include:

Wherein the target average value is an average value of the target parameter values.
For example, the target display parameters include: the first parameter values include at least one luminance parameter value (corresponding to the target parameter value) and at least one chrominance parameter value (corresponding to the target parameter value). Taking a chromaticity parameter as an example, if the first parameter value includes a chromaticity parameter value, determining the chromaticity parameter value as a reference parameter value corresponding to the chromaticity parameter; if the first parameter value includes at least two chroma parameter values, calculating an average value of all the chroma parameter values, determining a chroma parameter value p closest to the average value in all the chroma parameter values, and determining the chroma parameter value p as a reference parameter value of a corresponding chroma parameter. The principle of determining the reference parameter value of the luminance parameter is the same as that of determining the reference parameter value of the chrominance parameter, and will not be described herein.
Optionally, step 103: determining a first parameter value of the target display parameter of the second target sub-display area from the first optical signal may comprise:
converting the first optical signal into a first electrical signal; and determining a first parameter value of the target display parameter corresponding to the first electric signal according to a preset corresponding relation between the electric signal and the parameter value of the target display parameter.
In the embodiment of the application, after the photoelectric conversion panel receives the first optical signal, the first optical signal can be converted into the first electrical signal, and then the electronic equipment can determine the first parameter value of the target display parameter corresponding to the first electrical signal according to the preset corresponding relation between the electrical signal and the parameter value of the target display parameter. For example, taking the target display parameter as the luminance parameter and the first electrical signal as the current, the correspondence between the current value and the luminance value is preset, and after the corresponding current value is obtained according to the first optical signal, the corresponding luminance value (i.e., the first parameter value corresponding to the luminance parameter) may be determined according to the preset correspondence.
Optionally, in the embodiment of the present application, in order to improve the calibration effect of the display consistency of the screen, the target screen after the parameter value is adjusted may be checked to determine whether the display parameter of the target screen meets the preset condition, so in step 105: after setting the parameter value of the target display parameter of the entire display area of the target screen as the reference parameter value, the screen display calibration method may further include:

The second optical signal is received by the photoelectric conversion panel arranged at the first target sub-display area and is emitted from the second target sub-display area arranged opposite to the first target sub-display area.
The preset conditions are that parameter values of the same target display parameter are all in a preset range. After readjusting the parameter values, similar verification can be performed again until the parameter values of the target display parameters meet preset conditions.
