Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.

Organic light emitting diode (Organic Light Emitting Diode, OLED) display panels are increasingly being used in the market due to their high sensitivity, high contrast, wide viewing angle, low power consumption, and low volume.

When the OLED display panel is used as a display panel of the hidden camera scheme, in order to achieve higher transmittance, a high-transmittance region on the OLED display panel needs to use a different film material and driving mode from those of a non-high-transmittance region. For example, the anode and cathode materials adopted in the high-transmittance region are transparent conductive film materials, the non-high-transmittance region adopts a metal material, and the transmittance of the transparent conductive film material is higher than that of the metal material; the high transmittance region adopts a passive driving method, and the non-high transmittance region adopts an active driving method, wherein the passive driving method does not need to be provided with a thin film transistor compared with the active driving method, so that the transmittance is high.

Because the high-transmittance region is different from the non-high-transmittance region in film material and driving mode (film structure), the service life of the high-transmittance region is lower than that of the non-high-transmittance region, and when the same service time is reached, the loss of the high-transmittance region is higher than that of the non-high-transmittance region, so that the non-uniformity of the high-transmittance region and the non-high-transmittance region is displayed.

It should be noted that the high transmittance region described above may be used to hide other components such as a light sensor (lightsensor) besides the front camera.

At least one embodiment of the present disclosure provides a display control method, which applies a display panel, and fig. 1 is a schematic structural diagram of a display panel according to an exemplary embodiment. Referring to fig. 1, the display panel 100 includes a first display area 101 and a second display area 102, the second display area 102 surrounds the first display area 101, and the first display area 101 is disposed near one side of the second display area 102. The transmittance of the first display region 101 is higher than that of the second display region 102, that is, the first display region 101 is the aforementioned high transmittance region, and the second display region 102 is the aforementioned non-high transmittance region. Fig. 2 is a schematic application diagram of the display panel in fig. 1, referring to fig. 2, the display panel 100 is applied in a terminal device 10 (such as a mobile terminal), and in the terminal device 10, a front camera or a light sensor and other components 20 may be disposed at a position corresponding to the first display area 101.

Fig. 3 is a hierarchical structure diagram of the display panel 100. Referring to fig. 3, the display panel 100 includes a substrate 110, an array structure 120, an organic light emitting material layer 130, and a cathode layer 140 sequentially on the substrate 110 (e.g., a glass substrate). Wherein the difference in the service lives of the first display region 101 and the second display region 102 may be caused by at least one of a film material and a film structure. For example, the array structure 120 and the cathode layer 140 of the first display region 101 are made of a high-transmittance material, and the array structure 120 and the cathode layer 140 of the second display region 102 are made of a general-transmittance material, and the service life of the high-transmittance material is lower than that of the general-transmittance material. For another example, the array structure 120 of the second display area 102 includes a thin film transistor array and an anode connected to the thin film transistor array, that is, the second display area 102 adopts an active driving mode, and the array structure 120 of the first display area 101 only includes an anode array, that is, the first display area adopts a passive driving mode, and due to the difference of the film structures of the two, the service life of the passive driving mode is lower than that of the active driving mode.

It should be noted that, one high transmittance region may be provided on the display panel, or two or more high transmittance regions may be provided.

Fig. 4 is a flowchart illustrating a display control method according to an exemplary embodiment. Referring to fig. 4, the method may be performed by a display panel or a terminal device having the display panel, for example, by a driving circuit in the display panel, typically an integrated circuit, or a controller in the terminal device, typically an integrated circuit or a processing chip, and the display control method may include:

in step S11, a first display control parameter of the first display area and a second display control parameter of the second display area are determined, respectively.

The first display control parameter is used for indicating the corresponding relation between the gray scale and the first data voltage, and the second display control parameter is used for indicating the corresponding relation between the gray scale and the second data voltage.

Optionally, the first data voltage and the second data voltage corresponding to the same gray scale are different.

Here, the first display control parameter may be a parameter for correcting the high transmittance region, and the second display control parameter may be a parameter for correcting the non-high transmittance region, and the high transmittance region has a shorter service life, so that the aging degree of the high transmittance region in the use process is higher than that of the non-high transmittance region, and the loss is higher than that of the non-high transmittance region, so that the same gray scale effect as that of the non-high transmittance region, that is, the first data voltage corresponding to the same gray scale is higher than the second data voltage, needs to be achieved by using a larger data voltage.

In the embodiment of the present disclosure, step S11 may be periodically performed, and after step S11 is completed, step S12 is performed during a next period of time according to the display control parameter. Step S11 may be performed by event triggering, for example, when the user turns on the display correction function, step S11 may be performed.

Alternatively, the display control parameter may be a Gamma curve, or a display correction coefficient for correcting the Gamma curve used in the first display area. Here, the Gamma curve is a correspondence relationship between the data voltage and the luminance (gray scale). The Gamma curve used in the first display area refers to the Gamma curve used in the first display area of the display panel at the beginning of step S11.

In step S12, the first display area and the second display area of the display panel are controlled to display by using the first display control parameter and the second display control parameter, respectively.

The difference between the brightness of the first display area when the first gray scale is displayed by the first data voltage and the brightness of the second display area when the first gray scale is displayed by the second data voltage is a first brightness difference, and the difference between the brightness of the first display area when the first gray scale is displayed by the second data voltage and the brightness of the second display area when the first gray scale is displayed by the second data voltage is a second brightness difference, wherein the first brightness difference is smaller than the second brightness difference.

Wherein the difference in luminance characterizes the magnitude of the difference between the luminances. If the first display area uses the first data voltage to display the first gray scale luminance is the first luminance, and the second display area uses the second data voltage to display the first gray scale luminance is the second luminance, the difference between the two luminances (the first luminance difference) is the absolute value of the difference between the first luminance and the second luminance. If the first display area uses the second data voltage to display the first gray scale with the brightness being the third brightness and the second display area uses the second data voltage to display the first gray scale with the brightness being the fourth brightness, the difference between the two brightness (the second brightness difference) is the absolute value of the difference between the third brightness and the fourth brightness.

For example, when the display control parameter (the first display control parameter or the second display control parameter) is a Gamma curve, step S12 may include: and selecting corresponding data voltages from the Gamma curve according to the gray scale values, and controlling pixels to display by adopting the selected data voltages.

When the display control parameter is a display correction coefficient, step S12 may include: the Gamma curve used in the first display area is adjusted by adopting the display correction coefficient; and selecting corresponding data voltages from the adjusted Gamma curve according to the gray scale values, and controlling pixels to display by adopting the selected data voltages.

In the embodiment of the disclosure, in the display control method, the first display area and the second display area of the display panel are respectively controlled by adopting the first display control parameter and the second display control parameter, and under the control of the first display control parameter and the second display control parameter and under the control of the first data voltage and the second data voltage, the brightness difference between the first display area and the second display area is smaller than the brightness difference when the first display area and the second display area are simultaneously controlled by adopting the second data voltage, so that the display difference between the first display area and the second display area is reduced. For example, the method can compensate for the brightness loss caused by the high loss of the first display area, so that the display difference between the first display area and the second display area is reduced, and the uniformity of the display panel is improved.

Optionally, determining the first display control parameter of the first display area includes: acquiring display parameters of a first display area, wherein the display parameters comprise: displaying at least one of the duration, the brightness corresponding to the binding point gray scale voltage, the chromaticity corresponding to the binding point gray scale voltage and the current corresponding to the binding point gray scale voltage; a first display control parameter is determined based on the display parameter of the first display area.

Wherein at least one means that the display parameters include one, two, three or all of the four types. For example, in the method, the first display control parameter may be determined only according to the display duration, or may be determined together according to the display duration and the brightness corresponding to the gray-scale voltage of the binding point, which is not limited in this application.

Optionally, the display parameters include brightness corresponding to the gray-scale voltage of the binding point or chromaticity corresponding to the gray-scale voltage of the binding point, and the obtaining the display parameters of the first display area includes:

outputting a display parameter acquisition instruction, wherein the display parameter acquisition instruction is used for indicating a user to place the display panel in an environment with low brightness of ambient light; and after receiving a confirmation instruction of a user, acquiring display parameters of the first display area.

Alternatively, the acquisition of the display parameters of the first display area may also be implemented in combination of the two modes, that is: outputting a display parameter acquisition instruction; after receiving a confirmation instruction of a user, acquiring ambient light information; and when the brightness of the ambient light is smaller than a first threshold value, acquiring the display parameters of the first display area.

Optionally, the first display control parameter is one of a plurality of Gamma curves, where the plurality of Gamma curves respectively correspond to a plurality of different phases, the different phases are represented by different display parameter ranges, and determining the first display control parameter based on the display parameter of the first display area includes:

and determining the Gamma curve corresponding to the display parameter range of the display parameter of the first display area based on the corresponding relation between the display parameter range and the Gamma curve.

Optionally, the first display control parameter is one of a plurality of display correction coefficients, where the plurality of display correction coefficients respectively correspond to a plurality of different phases, and the different phases are represented by different display parameter ranges, and determining the first display control parameter based on the display parameter of the first display area includes:

and determining a display correction coefficient corresponding to the display parameter range of the display parameter of the first display area based on the corresponding relation between the display parameter range and the display correction coefficient, wherein the display correction coefficient is used for correcting the initial Gamma curve.

In this implementation manner, two methods for determining display control parameters based on display parameters of a first display area are provided, one method is to directly determine a Gamma curve, and the other method is to obtain a coefficient for adjusting the Gamma curve used in the first display area, and both methods can obtain new Gamma curves suitable for the current display panel, so as to ensure display uniformity.

Optionally, determining the first display control parameter based on the display parameter of the first display area includes: comparing the difference between the display parameter of the first display area and the reference display parameter; and when the difference exceeds the second threshold, determining a first display control parameter.

The reference display parameter may be a display parameter of the second display area or a display parameter of the first display area before a period of time.

Optionally, determining the first display control parameter based on the display parameter of the first display area includes: acquiring a difference value between the display parameters of the first display area and the display parameters of the second display area; when the difference exceeds a threshold, a first display control parameter is determined.

Optionally, determining the first display control parameter based on the display parameter of the first display area includes: and acquiring the variation of the display parameters of the first display area in the first designated time period, and determining the first display control parameters when the variation exceeds a threshold value.

Alternatively, in determining the first display control parameter, the display parameter variation condition of the second display area may be considered simultaneously in addition to the display parameter variation condition of the first display area. For example, determining the first display control parameter based on the display parameter of the first display area includes: the method comprises the steps of obtaining a first variable quantity of a display parameter of a first display area in a second designated time period and a second variable quantity of the display parameter of the second display area in the second designated time period, and determining a first display control parameter when the difference between the first variable quantity and the second variable quantity exceeds a preset difference value.

Optionally, the first display control parameter and the second display control parameter each include a display control parameter corresponding to each color channel.

Optionally, performing display correction on the display panel using the first display control parameter includes:

the determined data voltages of the sub-pixels of the first display area are input into the sub-pixels of the first display area, and the determined data voltages of the sub-pixels of the second display area are input into the sub-pixels of the second display area.

It should be noted that the foregoing steps S11-S12 may be arbitrarily combined with the foregoing optional steps and between the foregoing optional steps.

It should be noted that, the correction method of the display characteristic of the second display area may be performed in a similar manner to that of the first display area. This disclosure is not repeated here.

Fig. 5 is a flowchart illustrating a display control method according to an exemplary embodiment. Referring to fig. 5, the method may be performed by a display panel or a terminal device having the display panel, for example, by a driving circuit in the display panel, typically an integrated circuit, or a controller in the terminal device, typically an integrated circuit or a processing chip, and the display control method may include:

in step S21, display parameters of the first display area are acquired.

Optionally, the display parameters include: at least one of display duration of the first display area, brightness corresponding to the binding point gray scale voltage, chromaticity corresponding to the binding point gray scale voltage and current corresponding to the binding point gray scale voltage. Chromaticity refers to the saturation of a color.

In the implementation manner, the display condition of the current first display area can be accurately determined through information such as brightness, chromaticity, current and the like, so that display correction is performed according to the display condition; the display effect of the first display area is worse as the display duration increases, so that the display control parameter can be determined according to the display duration.

The display duration is the time of cumulative display of the display panel, and the time is usually recorded by a controller of the display panel or a controller of the mobile terminal, for example, a counter or a timer in the controller may be used to record the time of cumulative display of the display panel, when the display panel is started and operated, the counter or the timer is operated, and when the display panel is ready to be shut down and stopped, the recorded result is stored. Thus, when the display parameter includes a display duration, step S21 may include: and acquiring the display time length recorded by the controller of the display panel or the controller of the mobile terminal.

The gray scales of the binding points are usually gray scales stored in a driving circuit of the display panel in a Gamma curve, and although the Gamma curve corresponds to the data voltages of each gray scale, in order to reduce the storage space, only the data voltages of several gray scales of the binding points, for example, 8 gray scales of the binding points, are stored in the driving circuit, and the data voltages of other gray scales can be calculated according to the voltages. Binding point gray scale voltage is the data voltage of the binding point gray scale. The binding points are key points selected from 0 to 255 gray scales, for example, 31, 63, 95, 127, 159, 191, 223 and 255, and according to the data of the key points, the driving circuit or the controller can calculate the data of any gray scale.

Further, when obtaining the display parameters such as the brightness corresponding to the gray-scale voltage of the binding point, the chromaticity corresponding to the gray-scale voltage of the binding point, and the current corresponding to the gray-scale voltage of the binding point, the display parameters can be obtained when the first display area displays a single-color picture or when the first display area displays a multiple-color picture. Wherein, the single-color picture refers to a red, green or blue picture, and the multiple-color picture refers to a pure-color picture obtained by combining at least two of three single colors, such as a white picture.

When a monochromatic picture is displayed, a display parameter corresponding to the gray level of the binding point is obtained, for example, when blue light is displayed, the display parameter corresponding to the gray level of the binding point is obtained, at this time, the red sub-pixel and the green sub-pixel in each pixel are both 0 gray level, and the blue sub-pixel is non-0 gray level, so that the monochromatic-blue color is displayed, and then the display parameter is detected. In the method of acquiring the display parameters corresponding to the gray scale of the binding point when the monochrome picture is displayed, different monochrome colors can be sequentially displayed, and then the display parameters are respectively acquired, for example, red, green and blue are sequentially displayed.

And when the complex color picture is displayed, the display parameters corresponding to the gray scales of the binding points are obtained, for example, when white light is displayed, the display parameters corresponding to the gray scales of the binding points are obtained, at this time, all the color sub-pixels in the first display area adopt the same gray scales to display the white light, and then the display parameters are detected.

The second display area may not be displayed when the display parameters of the first display area are detected, thereby reducing interference with the display parameters of the first display area.

The brightness or chromaticity can be detected by a photodetection device disposed opposite to and far from the first display area of the display panel, wherein the display area refers to a surface of the display panel where the first display area and the second display area emit light simultaneously, i.e. a surface of the display panel disposed on the terminal device facing the outside (user). The photodetection device includes at least one of a camera and a photosensor, for example, acquires an electric signal output by the camera or the photosensor, and converts the electric signal into at least one of chromaticity and luminance.

It should be noted that, before the camera is used to collect the luminance or chrominance information of the first display area, the method may further include: the camera is calibrated for brightness or chromaticity, which is usually done at the factory. When the light sensor is used for collecting the brightness or chromaticity information of the first display area, the light sensor has the capability of deducting the influence of ambient light on the collected information, and the capability can be realized through an algorithm obtained through detection in advance.

In an implementation manner of the embodiment of the present disclosure, when the display parameter includes a luminance corresponding to the binding point gray scale voltage or a chromaticity corresponding to the binding point gray scale voltage, step S21 may include:

In the implementation manner, two implementation manners of acquiring the display parameters are provided, wherein the first is an automatic acquisition manner and the second is a manual acquisition manner, and the display parameters can be acquired through the two implementation manners, so that a basis is provided for subsequent display correction. Since the transmittance of the first display region is high, it is necessary to acquire the display parameters in an environment where no or little ambient light is present, for example, at night or in a dark place, in order to avoid interference of the display parameters by the external ambient light.

When the display parameter includes a current corresponding to the gray-scale voltage of the binding point, step S21 may include: the voltage of a detection resistor in a driving circuit of the first display area is acquired, and a current is determined according to the voltage of the detection resistor. Since the first display area and the second display area are individually wired, the detection resistor may be a resistor provided in a driving circuit of the first display area (e.g., a resistor provided on a flexible circuit board) through which current detection can be achieved. The number of the detection resistors may be one or a plurality of.

In step S22, the difference between the display parameter of the first display area and the reference display parameter is compared. When the difference exceeds the second threshold, step S23 is performed.

And when the difference value does not exceed the second threshold value, exiting the current flow. At this time, the first display control parameter of the first display area is the same as the second display control parameter of the second display area, and belongs to the display panel which is just put into use, and at this time, the loss degree of the first display area is smaller and correction is not needed.

The reference display parameter may be a set of luminance, chromaticity or current detected in advance and stored in the display panel or the mobile terminal. The reference display parameter may also be detected in real time, for example, when a current is used as the display parameter, the reference display parameter may be a current value of the same gray scale of the second display area detected in real time. The reference display parameter may also be a fixed value, for example, when a display period is used as the display parameter, the reference display parameter may be 0.

In step S23, a first display control parameter is determined based on the display parameter of the first display area.

Optionally, the first display control parameter is one of a plurality of Gamma curves, where the plurality of Gamma curves are all stored in a driving circuit of the display panel, the plurality of Gamma curves respectively correspond to a plurality of different phases, the different phases are represented by different display parameter ranges, and determining the first display control parameter based on the display parameter of the first display area includes:

For example, the different display stages are represented by different brightness ranges, e.g., the first stage brightness ranges from A1 to A2, the second stage brightness ranges from A2 to A3, and so on, wherein A1, A2, A3 are gradually reduced.

In different Gamma curves, at least part of data voltages corresponding to gray scales are different. For display parameters such as brightness, chromaticity, current and the like, the smaller the display parameter range is, the larger the data voltage corresponding to the same gray scale is in the corresponding Gamma curve. For time, the larger the display parameter range, the larger the data voltage corresponding to the same gray scale in the corresponding Gamma curve.

Optionally, the first display control parameter is one of a plurality of display correction coefficients, the plurality of display correction coefficients are all stored in a driving circuit of the display panel, the plurality of display correction coefficients respectively correspond to a plurality of different stages, the different stages are represented by different display parameter ranges, the first display control parameter is determined based on the display parameter of the first display area, and the method includes:

And determining a display correction coefficient corresponding to the display parameter range of the first display area based on the corresponding relation between the display parameter range and the display correction coefficient, wherein the display correction coefficient is used for correcting the Gamma curve used in the first display area.

Further, the method may further include: and acquiring a corresponding relation between the display parameter range and the Gamma curve, or a corresponding relation between the display parameter range and the display correction coefficient. The process of obtaining the above correspondence relationship may be obtained by a life test.

Fig. 6 is a schematic diagram of a Gamma curve at different stages according to an embodiment of the disclosure, referring to fig. 6, curve 1 is an initial Gamma curve, curve 2 is a Gamma curve after a period of use, and the Data (Data) voltage required for the same brightness increases with the lapse of time. And different Gamma curves are adopted at different times, so that the display correction of the first display area can be realized.

In the embodiment of the present disclosure, the correspondence between the display parameter range and the display correction coefficient mentioned in the second mode may be stored in the controller of the display panel or the controller of the mobile terminal in advance, or may be generated in real time by the controller of the display panel or the controller of the mobile terminal. For example, the data voltages of the binding point gray scales of the first display area in a plurality of stages or the brightness, chromaticity or current variation fitting function of the first display area is stored in advance, the brightness, chromaticity or current variation fitting function is a fitting function of brightness, chromaticity or current variation along with the display duration, and the corresponding relation between the display parameter range and the display correction coefficient is determined based on the data voltages of the binding point gray scales of the first display area in a plurality of stages or the brightness, chromaticity or current variation fitting function of the first display area.

The corresponding relation between the display parameter range and the display correction coefficient is determined based on the brightness, chromaticity or current variation fitting function of the first display area, and the display correction coefficient may be determined based on the brightness, chromaticity or current variation fitting function of the first display area and the relation between the brightness, chromaticity or current and the data voltage. Here, the relation between luminance, chromaticity, or current and data voltage is known in advance. For example, the brightness is proportional to the voltage to the power N, N is a Gamma value, and based on this relationship, a display correction coefficient can be determined. For example, y=x in the initial Gamma curve ^2.2 Z=X in Gamma curve after a period of time ^2.2×n X is a data voltage, Y, Z is brightness, and n is a display correction coefficient. Based on the brightness change fitting function, the initial brightness Y and the current brightness Z can be determined, and based on the formula, the value of n can be determined, so that the corresponding relation between the display parameter range and the display correction coefficient is obtained.

For the method of determining the corresponding relation between the display parameter range and the display correction coefficient based on the data voltage of the binding point gray scale of the first display area in a plurality of stages, the display correction coefficient can be determined according to the relation between the brightness, the chromaticity or the current and the data voltage, so as to obtain the corresponding relation between the display parameter range and the display correction coefficient.

In fig. 7, the horizontal axis represents time, the vertical axis represents brightness of the first display area, the brightness of the first display area in fig. 7 is generated under the action of the data voltage of the same binding point gray scale, and referring to fig. 7, three lines represent brightness when different monochrome pictures of red, green and blue are displayed, and it can be seen that the brightness of any color picture gradually decreases with time. It should be noted that, fig. 7 shows a curve of a fitting function of the brightness of light emitted by the sub-pixels of three different colors at the same gray scale voltage, and it can be seen that the attenuation degrees of the sub-pixels of different colors are different.

In the embodiment of the present disclosure, the steps S21 to S23 may be performed periodically, for example, once every 30 days, and after the step S23 is completed, the display panel only needs to acquire the first display control parameter to control the first display area to display in a next period of time. The steps S21 to S23 may be performed aperiodically, and in conjunction with fig. 7, for example, under the action of a data voltage of a gray level of a certain binding point, the steps S21 to S23 are performed once to obtain a first display control parameter, and then the display panel only needs to obtain the first display control parameter to control the first display area to display. Step S22 is an optional step. The steps S21-S23 may be executed by event triggering, for example, when the user turns on the display correction function, the steps S21-S23 are executed to obtain the first display control parameter, and then the display panel only needs to obtain the first display control parameter to control the first display area to display.

When the display panel displays each picture, the display panel needs to acquire a second display control parameter in addition to the first display control parameter, and the second display control parameter may be determined in advance or may be a fixed parameter. For example, the second display control parameter may be determined in advance in the same manner as the first display control parameter, and then the second display control parameter is acquired at the time of each screen display, and when the second display control parameter is determined, the display parameter of the second display area may include only at least one of the display duration and the current corresponding to the binding point gray scale voltage. For another example, the second display control parameter may be a fixed Gamma curve, which does not need to be determined in advance, and the second display control parameter may be acquired when each picture is displayed, in which case the second display area may be internally compensated to complete display correction, and the display correction is implemented by changing a circuit structure (such as a threshold compensation circuit such as 6T 1C) in the array structure.

In step S24, the gray scale of each sub-pixel located in the first display area and the gray scale of each sub-pixel located in the second display area in the target screen are acquired.

In step S25, determining a data voltage of each sub-pixel of the first display area of the display panel based on the first display control parameter and the gray scale of each sub-pixel located in the first display area; based on the second display control parameter and the gray scale of each sub-pixel located in the second display area, the data voltage of each sub-pixel of the second display area of the display panel is determined.
