Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the disclosure, as detailed in the appended claims.
In the related art, the OLED is a current-type organic light emitting device, and light emission occurs due to injection and recombination of carriers, and the light emission intensity is proportional to the magnitude of the injected driving current. When the mode of local area highlighting is performed using the OLED panel in the terminal, it is necessary to increase the current of the local area to increase the gray-scale luminance of the local area. However, the increase of the local area current causes the driving current of the line on which the local area in the OLED screen is located to be overloaded, and the driving current around the local area is too low, so that a dark band of brightness attenuation occurs between the local area and other areas. For example, in a fingerprint unlocking scene under a screen, in order to ensure that the acquired fingerprint image is clear, when fingerprint information is read, the voltage of a display driving chip is increased to enable a fingerprint area to enter a highlight display mode. In order to save power consumption, only the fingerprint area is put into a highlight display mode, and the other areas still keep Normal brightness, but due to the characteristics of the OLED panel, a dim band with attenuated brightness exists between the highlight area and the Normal brightness area due to the IR drop (line resistance loss) phenomenon of local highlight, so that the user experience is influenced.
The application provides a brightness adjusting method, which can determine the compensation voltage of a dark band area between a highlight display area and a normal display area based on the current gray scale brightness of the normal display area when the highlight display area is triggered to execute specified brightness display, so as to compensate the dark band area, eliminate the visual influence of the dark band area on a user during use, and further improve the use experience of the user.
In the embodiments of the present disclosure, for convenience of description, the highlight display area is referred to as a first display area, the normal display area is referred to as a second display area, and a transition display area between the first display area and the second display area, that is, an area where a dark band phenomenon occurs, is referred to as a third display area.
The brightness adjusting method provided in the present disclosure is applied to a terminal having a display screen. In one example, the class of terminals may include mobile terminals, such as: cell phones, tablets, ipods, etc. In another example. The structure of the terminal may include: a dual-screen terminal, a folding screen terminal, a full-screen terminal, etc.
Fig. 1 is a flow chart illustrating a brightness adjustment method according to an exemplary embodiment. As shown in fig. 1, a brightness adjustment method is used in a terminal, a display area of a display screen of the terminal includes a first display area and a second display area, and the brightness adjustment method includes the following steps S11 to S12.
In step S11, if it is determined that the condition for triggering the first display area to perform the designated brightness display is satisfied, the current gray-scale brightness of the second display area is obtained.
In step S12, based on the mapping relationship between the gray-scale brightness of the second display region and the compensation voltage, the compensation voltage corresponding to the current gray-scale brightness is determined, and the determined compensation voltage is compensated for the third display region, so that the gray-scale brightness of the third display region is consistent with the gray-scale brightness of the first display region.
In the embodiment of the disclosure, the display area of the terminal display screen comprises a first display area triggered to display the designated brightness. In one example, the first display area may be, for example, an off-screen fingerprint highlight area.
In the embodiment of the present disclosure, when the first display region displays the specified luminance, the display region of the display screen includes the first display region and the second display region. When the first display area is triggered to display with appointed brightness, the gray-scale brightness of the first display area is higher than that of the second display area, the current required by the first display area is overloaded, and further the current of a partial area of the second display area around the first display area is reduced, so that the voltage actually used for driving display in the partial area is reduced, further the actual gray-scale brightness of the partial area in the second display area is reduced, a dark band phenomenon occurs, and a third display area is formed.
In order to eliminate the dark band phenomenon in the third display region, the mapping relationship between the gray-scale brightness of the second display region and the compensation voltage of the third display region is preset in the embodiment of the disclosure. In the embodiment of the present disclosure, the compensation voltage of the third display region may be understood as a difference between a voltage providing ideal gray-scale luminance (actual gray-scale luminance of the second display region) of the third display region and a voltage providing actual gray-scale luminance of the third display region. When the brightness is adjusted, the driving current of the third display area is increased through the compensation voltage, so that the gray scale brightness of the third display area is consistent with that of the second display area, and the visual influence caused by the dark band of the third display area is eliminated.
In one implementation scenario, the driving display circuit of the OLED panel is shown in fig. 2. The luminance of an OLED panel is mainly determined by the magnitude of the driving current flowing through the EL. The working principle is as follows: when a scanning line (Scan) of the OLED screen is selected, a switching tube (T1) is turned on, a Data voltage (Data voltage) charges a storage Capacitor (CS) through the T1 tube, and the voltage of the CS controls the drain current of a driving tube (T2); when Scan is not selected, T1 is turned off, the charge stored on CS continues to maintain the gate voltage of T2, T2 remains on, and is thus in communication with the EL source voltage (ELVSS voltage). As can be seen from fig. 2, the magnitude of the driving current is controlled by the Data voltage (Data voltage) and the EL drain voltage (ELVDD voltage), and the relationship between the current flowing through the EL and the voltage is ID ∈ (VData-ELVDD) ^2. Since the ELVDD voltage is invariable, the Data voltage needs to be compensated in order to eliminate the influence of the dark band of the third display region. Therefore, the compensation voltage determined by compensating the third display area in the embodiment of the present disclosure may be understood as the compensation voltage determined by compensating the data voltage, so that the first display area and the second display area are smoothly transitioned, and the visual influence caused by the third display area is eliminated, thereby improving the use experience of the user.
Generally, when the first display area is triggered to display the designated brightness, the third display area appears, so in the embodiment of the present disclosure, when it is determined that the condition for triggering the first display area to display the designated brightness is satisfied, the current gray-scale brightness of the second display area is obtained.
In an embodiment, the condition that the first display region is triggered to perform the designated brightness display is met may include that a fingerprint chip in the terminal detects a fingerprint signal. That is, if the fingerprint chip in the terminal detects a fingerprint signal, it is determined that a condition for triggering the first display area to perform specified brightness display is satisfied. For example: based on the current use scene of the terminal, fingerprint verification is required, and the condition that the first display area performs specified brightness display is determined to be met according to the fact that a fingerprint chip in the terminal detects a fingerprint signal. The usage scenario may include: when the terminal is in standby state or waits to open a certain application, when the user uses fingerprint trigger to unlock, then fingerprint chip detects the fingerprint signal, confirms that first display area carries out appointed luminance display to the correct position of fingerprint unblock can be made clear and definite fast to the user, and the terminal can in time respond, and then promotes the user and use the use of terminal and experience.
In another embodiment, the condition for triggering the first display region to perform the designated brightness display may be satisfied by triggering the first display region to perform the designated brightness display. That is, when the first display region is triggered to perform the specified luminance display, it is determined that a condition for triggering the first display region to perform the specified luminance display is satisfied.
Through the embodiment, under the condition that the first display area is triggered to display, the compensation voltage which corresponds to the current gray-scale brightness of the second display area and is used for compensating the third display area can be determined based on the mapping relation between the gray-scale brightness of the second display area and the compensation voltage, and the gray-scale brightness of the third display area is adjusted based on the compensation unit, so that the dark band phenomenon caused by the gray-scale brightness difference between the first display area and the second display area is eliminated.
In the embodiments of the present disclosure, the brightness adjusting method according to the above embodiments will be described below with reference to practical applications.
In one implementation scenario, as shown in fig. 3, the first display area is a fingerprint highlight display area under the screen, and the second display area is a normal display area of the OLED screen. When the fingerprint chip does not detect a fingerprint signal or the first display area is not triggered to perform specified brightness display, the first display area does not meet the condition of performing specified brightness display, so that the third display area does not appear in the OLED screen at this moment, the currently obtained application environment data voltage can be transmitted downwards, and data voltage compensation is not needed. When the fingerprint chip detects a fingerprint signal or the first display area is triggered to display by using the specified brightness, the first display area meets the condition of displaying the specified brightness. When the first display area is triggered to display the designated brightness, a third display area is formed. In order to eliminate the influence brought by the third display area, the current gray scale brightness of the current second display area is determined based on the currently acquired data voltage, and then the compensation voltage for compensating the third display area is determined based on the corresponding relation between the gray scale brightness of the second display area and the compensation voltage, so that the third display area is correspondingly compensated, the unlocking effect is optimized, the visual influence brought by the third display area is eliminated, and the use experience of a user is improved.
By applying the brightness adjusting method provided by the embodiment of the disclosure, in one implementation manner, the compensation voltage of the third area corresponding to different gray-scale brightness displayed in the second display area is predetermined, and then the mapping relation between the gray-scale brightness and the compensation voltage of the second display area is determined, so that corresponding compensation is performed on the third display area, and the visual influence brought to a user by the transition display area is eliminated.
Fig. 4 is a flowchart illustrating a method of determining a mapping relationship between a second display region and a compensation voltage according to an exemplary embodiment. As shown in fig. 4, determining the mapping relationship between the second display region and the compensation voltage includes the following steps S21 to S23.
In step S21, the gray-scale brightness of the first display region is maintained as the designated brightness, and the second display region is adjusted to display different gray-scale brightness.
In the embodiment of the disclosure, in practical applications, the designated brightness of the first display region triggered to be displayed is not adjustable, and the gray-scale brightness of the second display region provided by the terminal may be different in different scenes. For example, in one implementation scenario, the first display region is an off-screen fingerprint highlight display region, and the specified brightness of the first display region is 800 nits (nit). When the terminal triggers the fingerprint highlight display area under the screen to display in the unlocking scene and the payment scene, the gray scale brightness corresponding to the second display area in the terminal screen display area is different. For example, when the first display region is an under-screen fingerprint highlight display region, the gray-scale luminance of the second display region falls between 0 and 500 (nit). Therefore, when the compensation voltage is determined, the gray scale brightness of the first display area is kept unchanged, and the gray scale brightness of the second display area is adjusted to be different gray scale brightness, so that the compensation voltage for compensating the third display area under different gray scale brightness is determined.
For example, when the first display area is the under-screen fingerprint highlight display area and the compensation voltage corresponding to each gray-scale brightness of the second display area is determined, the gray-scale brightness of the first display area can be kept at 800 (nit) all the time, and a plurality of different gray-scale brightness of the second display area between 0 and 500 (nit) are continuously adjusted. For example, the gray-scale luminance of the second display region is adjusted to 100 (nit), 200 (nit), 300 (nit), 400 (nit), and 500 (nit).
In step S22, for each gray-scale luminance displayed in the second display region, the compensation voltage of the third display region corresponding to the gray-scale luminance of the second display region is determined.
In the embodiment of the disclosure, when the compensation voltage of the third display region corresponding to the gray-scale brightness of the second display region is determined, the gray-scale brightness of the third display region corresponding to each gray-scale brightness of a plurality of different gray-scale brightnesses for which the display of the second display region is adjusted may be detected, and the compensation voltage of the third display region may be determined based on the voltage for driving the corresponding gray-scale brightness.
In one example, the detected gray-scale brightness displayed in the second display region is referred to as a first gray-scale brightness, and the detected gray-scale brightness in the third display region is referred to as a second gray-scale brightness. And detecting second gray scale brightness displayed in the third display area when the first gray scale brightness is displayed in the second display area. And determining the difference value between the voltage for driving and displaying the first gray scale brightness and the voltage for driving and displaying the second gray scale brightness as the compensation voltage of the third display area.
For example, the gray-scale luminance of the second display region is 100 (nit), 200 (nit), 300 (nit), 400 (nit), and 500 (nit), the actual gray-scale luminance of the third display region is detected for 100 (nit), 200 (nit), 300 (nit), 400 (nit), and 500 (nit), respectively, and the compensation voltage of the third display region is determined based on the gray-scale luminance of the second display region (the ideal state gray-scale luminance of the third display region) and the actual gray-scale luminance of the third display region. Assume that the detected actual gray-scale luminance of the third display region is 95 (nit) when the gray-scale luminance of the second display region is 100 (nit). The compensation voltage of the third display region is a voltage difference between a voltage for driving the gray-scale luminance of 100 (nit) and a voltage for driving the gray-scale luminance of 95 (nit).
In step S23, a mapping relationship between the gray-scale luminance of the second display region and the compensation voltage is predetermined based on the compensation voltage of the third display region corresponding to each gray-scale luminance.
In the embodiment of the disclosure, after the compensation voltage corresponding to each gray scale brightness in the plurality of different gray scale brightness is determined, the mapping relationship between the gray scale brightness of the second display region and the compensation voltage can be determined.
In an implementation scenario, the mapping relationship between the gray-scale luminance of the second display region and the compensation voltage in the embodiment of the disclosure may be a curve relationship diagram between the gray-scale luminance value of the second display region and the compensation voltage. FIG. 5 is a graph illustrating a relationship between gray-scale luminance of a second region and compensation voltage according to an exemplary embodiment. Referring to fig. 5, when the gray-scale luminance values of the second display region are determined, the corresponding compensation voltages can be determined according to the corresponding curves.
The gray scale luminance values in fig. 5 can be understood as a plurality of different actual gray scale luminance values (ideal gray scale luminance values of the third display region) corresponding to the second display region when the first display region displays the designated luminance. The compensation voltage referred to in fig. 5 can be understood as a difference between a voltage value corresponding to a gray-scale luminance value corresponding to the actual gray-scale luminance value (the ideal gray-scale luminance value of the third display region) displayed in the second display region and a voltage value corresponding to a gray-scale luminance actual value corresponding to the third display region when the first display region displays the designated luminance.
In the embodiment of the disclosure, under the condition that the first display area is kept at the designated brightness, the gray scale brightness provided by the second display area is continuously changed, so as to determine the compensation voltage which needs to be compensated and corresponds to different gray scale brightness, thereby determining the mapping relation between the different gray scale brightness and the compensation voltage of the second display area.
In an embodiment, the gray-scale brightness of the corresponding display of the second display area is different in different application scenes.
In an example, different application scenarios in the embodiment of the present disclosure may also be understood as application operation scenarios corresponding to when the first display area is triggered to perform specified brightness display, for example, an unlocking scenario, a scenario for invoking a payment program, or a scenario for performing fingerprint identification verification on a user identity. Therefore, when the first display area is triggered to display the appointed brightness based on the terminal, the second display area is adjusted to display different gray scale brightness, and the compensation voltage corresponding to each gray scale brightness is determined, matching adjustment can be performed based on different application scenes, so that the obtained corresponding relation between the gray scale brightness and the compensation voltage is more practical.
In one example, the following method may be adopted when the second display area is adjusted to display different gray-scale brightness: and triggering the corresponding different application scenes when the first display area is subjected to appointed brightness display based on the terminal, and adjusting the gray scale brightness of the second display area to be matched with the gray scale brightness of the different application scenes. For example, the first display area is a fingerprint display area under a screen, and the corresponding application running scene includes an unlocking scene, a scene for calling a payment program and a scene for fingerprint identification verification of a user identity when the first display area is triggered to perform designated brightness display. When the gray scale brightness of the second area is adjusted, the gray scale brightness of the second display area can be adjusted to be matched with the gray scale brightness displayed when the unlocking scene is unlocked, the gray scale brightness matched with the payment program scene and the gray scale brightness matched with the fingerprint identification verification scene for the user identity.
According to the embodiment of the disclosure, for the gray scale brightness of different application scenes, the compensation voltage of the third display region corresponding to the gray scale brightness matched with the different application scenes can be determined, and the mapping relation between the gray scale brightness and the compensation voltage of the second display region matched with the different application scenes can be respectively determined based on the compensation voltage corresponding to the gray scale brightness matched with the application scenes.
In another embodiment, the embodiment of the present disclosure may determine a specified number of gray-scale luminances according to a gray-scale luminance display range of the second display region, and determine a correspondence between the gray-scale luminances of the second display region and the compensation voltage based on the specified number of gray-scale luminances.
In one example, when the gray-scale luminance range of the second display region is 0 to 500 (nit), and the designated number of the adjusted gray-scale luminance needs to be determined to be 5, 5 gray-scale luminance values may be selected from 0 to 500 (nit), and the gray-scale luminance value of the second display region may be adjusted to the selected gray-scale luminance value. For example, the selection of 5 gray levels may be 100 (nit), 200 (nit), 300 (nit), 400 (nit), and 500 (nit).
In the embodiment of the disclosure, when the specified number of gray-scale luminances are determined according to the gray-scale luminance display range of the second display area, the gray-scale luminance sub-range may be divided for the gray-scale luminance display range. In the embodiment of the present disclosure, the gray scale luminance display range may be divided equally or randomly, and the embodiment of the present disclosure is not limited. For example, when the gray-scale luminance display ranges are equally divided, the gray-scale luminance ranges obtained by dividing the gray-scale luminance range of 0 to 500 (nit) are 0 to 100 (nit), 101 to 200 (nit), 201 to 300 (nit), 301 to 400 (nit), and 401 to 500 (nit) 5 sub-display ranges, and 100 (nit), 200 (nit), 300 (nit), 400 (nit), and 500 (nit) are respectively used as the gray-scale luminance to be adjusted correspondingly.
After the specified number of gray scale brightness is determined in the embodiment of the present disclosure, the compensation voltage of the third display area corresponding to the specified number of gray scale brightness can be respectively determined. For example, when the gray-scale luminance of the second display region is 100 (nit), 200 (nit), 300 (nit), 400 (nit), and 500 (nit), the actual gray-scale luminance of the third display region is detected, and the compensation voltage of the third display region is determined based on the gray-scale luminance of the second display region (the ideal state gray-scale luminance of the third display region) and the actual gray-scale luminance of the third display region.
Further, in the embodiment of the disclosure, based on the specified number of gray-scale luminances and the compensation voltages corresponding to the specified number of gray-scale luminances, a functional relationship between the gray-scale luminances and the compensation voltages may be determined, and further, based on the functional relationship, a mapping relationship between the gray-scale luminances and the compensation voltages in the second display region within the gray-scale luminance display range may be determined. For example, in the embodiment of the present disclosure, according to the compensation voltage of the third display region corresponding to the specified number of gray-scale luminances, if it is determined that the functional relationship between the specified number of gray-scale luminances and the compensation voltage satisfies the linear curve functional relationship shown in fig. 5, it is determined that the mapping relationship between the gray-scale luminance and the compensation voltage of the second display region within the gray-scale luminance display range is the linear curve relationship shown in fig. 5.
It can be understood that, in order to obtain a more accurate mapping relationship, a sufficient number of gray scale brightness can be determined within a reasonable range, and further, the compensation voltage corresponding to each gray scale brightness is determined to be more targeted and accurate.
The brightness adjusting method provided by the embodiment of the disclosure can improve the dark band phenomenon generated between different display areas with different brightness displayed on the terminal display screen. A typical application scene is a scene in which the transition between a highlight area and a normal brightness area is smooth in the unlocking process of the fingerprint under the application screen in the fingerprint unlocking scene under the application screen.
In an example, the first display area is taken as a highlight display area when the finger print under the screen is unlocked, and the second display area is taken as a normal display area when the finger print under the screen is unlocked.
First, the panel area is divided into the first display area and the second display area shown in fig. 3 according to the panel characteristics. And the brightness of the highlight state of the first display area of the highlight display area is 800nit when the fingerprint is unlocked. The gray scale brightness of the second display area can be in different gray scale brightness within the range of 0-500 nit gray scale brightness according to the user scene. By applying the embodiment of the disclosure, when the first display area is measured at 800nit by using equipment in advance, the second display area is adjusted to have different gray scale brightness, and the gray scale brightness of the third display area under different gray scale brightness is detected. Based on the gray-scale luminance of the second display region and the gray-scale luminance of the third display region, a mapping relationship between the gray-scale luminance of the second display region and the compensation voltage of the third display region is determined, such as a curve relationship shown in fig. 5.
When the screen gray scale brightness is adjusted by applying the under-screen fingerprint unlocking, the Data sent by the AP end are compensated according to a relation curve of the third display area compensation voltage and the gray scale brightness of the second display area, which is obtained by testing in advance, so that the brightness of the third display area is the same as the brightness of the second display area, and the unlocking effect is optimized. Fig. 6 shows a flow of performing voltage compensation on the third display region by using the brightness adjustment method provided by the embodiment of the present disclosure. Referring to fig. 6, the Data voltage sent by the AP end is obtained, and it is determined whether the condition that the highlight display area is triggered to highlight is satisfied, for example, whether the HBM is turned on, if the HBM is turned on, it is determined that the condition that the highlight display area is triggered to highlight is satisfied, and it is determined that the compensation voltage compensates for the Data voltage. And if the HBM is not started, determining that the condition that the highlight display area is triggered to highlight display is not met, and directly outputting the Data voltage without compensating the Data voltage.
According to the brightness adjusting method provided by the embodiment of the disclosure, when the first display area is triggered to execute the specified brightness display, the compensation voltage is determined based on the current gray scale brightness of the second display area, and the third display area of the transition display area between the first display area and the second display area is compensated, so that the brightness of the third display area is consistent with that of the second display area, the visual influence of a dark band phenomenon occurring in the third display area on the use of a user is eliminated, and the use experience of the user is improved.
