Description

Technical Field

[0001] This disclosure relates to the field of data processing technology, and in particular to a display control method, electronic device, and storage medium. Background Technology

[0002] With the increasing popularity of electronic devices, their screen sizes are getting larger and larger, and full-screen devices are gradually gaining favor among users. Full-screen devices not only have a good appearance, but also have a higher screen utilization rate, allowing more screen content to be displayed.

[0003] To ensure the front-facing camera can capture clear images, related technologies employ special processing on the display screen within the camera's field of view. This includes reducing pixel density in this area, minimizing metal traces, or having a single transistor TFT drive multiple sub-pixels, thereby increasing light transmittance. For ease of explanation, the display area corresponding to the under-display camera will be referred to as the under-display camera display area (CUP), while the area outside will be called the normal area.

[0004] Taking a single transistor TFT driving multiple sub-pixels as an example, the driving current of the TFT in the CUP region is greater than that of the TFT in the Normal region. This results in a difference in the characteristic offset of the TFTs in the two regions, ultimately leading to a brightness difference between the CUP region and the Normal region, as shown in the image. Figure 1 As shown. See also Figure 1 (a) shows the brightness effect of the display screen at the initial moment; (b) shows the brightness effect of the display screen after 30 minutes of display; (c) shows the brightness effect of the display screen after 60 minutes of display.

[0052] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described below by way of example do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatus consistent with some aspects of this disclosure as detailed in the appended claims.

[0053] To address the aforementioned technical problems, this disclosure provides a display control method, an electronic device, and a storage medium. The inventive concept lies in analyzing the compensation principle of pixel circuits based on the discovered causes of characteristic shifts in transistor TFTs. Different pixel circuits can be used in different display areas (i.e., a first display area such as the CUP area and a second display area such as the normal area). For example, a first pixel circuit can be used in the first display area and a second pixel circuit in the second display area. By controlling the charging time of the storage capacitors in the first and second pixel circuits to be different, the brightness difference between the two display areas can be eliminated or mitigated. This achieves a display effect where the brightness of the first and second display areas remains consistent, which is beneficial for improving the viewing experience.

[0054] Figure 2 This is a block diagram illustrating an electronic device according to an exemplary embodiment. Figure 3 This is a schematic diagram illustrating the effect of two display areas of a display screen according to an exemplary embodiment. See also Figure 2 and Figure 3 An electronic device includes a display screen 10 having a first display area 11 and a second display area 12. The pixel density in the first display area 11 is lower than the pixel density in the second display area 12. Pixels in the first display area 11 use a first pixel circuit (not shown in the figure), and pixels in the second display area 12 use a second pixel circuit (not shown in the figure); the charging times of the storage capacitors (Cst) in the first and second pixel circuits are different. The storage capacitors are used to store pixel data corresponding to the pixels, so that the pixels display grayscale or brightness matching the pixel data.

[0055] It should be noted that the pixel density in the first display area 11 is lower than that in the second display area 12 in order to improve the light transmittance of the first display area 11. At this time, an optical device such as a camera or a light sensor can be set below the first display area 11 to ensure the detection efficiency of the optical device.

[0056] In one embodiment, the compensation signal of the first pixel circuit is related to the pixel data (i.e., data). That is, when the first pixel circuit compensates for the characteristic offset of the driving transistor TFT, its compensation signal comes from the pixel data. Alternatively, when compensating for the characteristic offset of the driving transistor TFT in a given pixel, because the pixel data displayed in each row of pixels needs to be updated, the compensation signals of adjacent rows of pixels are unrelated. Therefore, it is impossible to compensate for the characteristic offset of the next row of pixels, or in other words, the compensation period of the first pixel circuit is equal to the row period. In one example, the first pixel circuit can be implemented using a 7T1C circuit structure.

[0057] In one embodiment, the compensation signal of the second pixel circuit is related to a preset control signal (such as a preset control signal comp), and the preset control signals of adjacent rows of pixels overlap. That is, the compensation period of the second pixel circuit is independent of the row period, allowing for simultaneous compensation for characteristic offsets for both the current row of pixels and the next row of pixels. In one example, the second pixel circuit can be implemented using a 6T2C circuit structure.

[0058] Thus, the solution provided in this embodiment of the present disclosure, by employing a first pixel circuit for pixels in the first display area and a second pixel circuit for pixels in the second display area, and by making the charging time of the storage capacitors in the first pixel circuit and the second pixel circuit different, can achieve a display effect in which the brightness of the first display area and the second display area are consistent, which is beneficial to improving the viewing experience.

[0059] In one embodiment, see further. Figure 2 The electronic device also includes a driving circuit 30. This driving circuit 30 can drive pixels within a first display area. The driving circuit 30 may include multiple driving transistors (not shown in the figure), each driving transistor driving a preset number of sub-pixels within the first display area 11, where the preset number is an integer greater than or equal to 2. For example, each driving transistor can drive 2, 3, or 4 sub-pixels. Understandably, as the number of sub-pixels driven by each driving transistor increases, the current flowing through the driving transistor increases, and the characteristic offset of the driving transistor increases, causing the brightness of the first display area to be greater than the brightness of the second display area. Therefore, a compensation signal for the second display area is increased, i.e., the charging time of the storage capacitor in the second display area is extended. In other words, the charging time is positively correlated with the preset number.

[0060] It should be noted that extending the charging time increases the overlap time of the preset control signals of two adjacent rows of pixels, which means increasing the width of the overlap area of ​​the preset control signals of two adjacent rows of pixels. Since the width of the overlap area has a maximum value, as will be discussed later... Figure 11When the rightmost edge of comp(n) coincides with the leftmost edge of scan(n) when it is a low-level signal, the width of the overlapping region of comp(n) and comp(n+1) is at its maximum value. It is understandable that the charging time cannot exceed this maximum value. In other words, the positive correlation between the charging time and the preset quantity is within a certain range.

[0061] Thus, the solution provided in this embodiment adjusts the charging time of the stored content in the second display area according to the number of sub-pixels driven by the driving transistor in the first display area, which can achieve a display effect in which the brightness of the first display area and the second display area are consistent, which is beneficial to improving the viewing experience.

[0062] In practical applications, considering that the charging time is fixed after the electronic device leaves the factory, the brightness difference between the first and second display areas increases with the duration of screen display. Therefore, in one embodiment, the electronic device can dynamically adjust the charging time. The electronic device stores a preset correspondence between display duration and charging time; for example, when the display duration is 30 minutes, the charging time is a1 ns, and when the display duration is 60 minutes, the charging time is a2 ns. Thus, in this example, by dynamically adjusting the charging time of the content stored in the second display area, a consistent brightness between the first and second display areas can be achieved, which is beneficial for improving the viewing experience.

[0063] The adjustment process of the above-mentioned electronic device is described below, with the first pixel circuit in the first display area implemented using a 6T2C circuit structure and the second pixel circuit in the second display area implemented using a 7T1C circuit structure.

[0064] First, the working process of the first pixel circuit using the 6T2C circuit structure includes:

[0065] 1. Initialization Phase

[0066] Referring to Figures 4(a) and 4(b), when em is a low-level signal, scan(n) is a high-level signal, and comp is a low-level signal, transistors T2, T3, T4, and T6 are in the on state, and the driving transistor DTFT is in the on state, while the other transistors are in the off state. At this time, the potentials at nodes a and b are equal, that is, the storage capacitor Cst is initialized VA=VB=Vint in preparation for writing pixel data Vdata later.

[0067] It should be noted that, for ease of understanding of the accompanying drawings, a rectangular marker block is provided near the transistor in the on state in each example of this disclosure. At the same time, an arrow indicating the direction of current flow is set.

[0068] 2. Compensation Phase

[0069] Referring to Figures 5(a) and 5(b), when em is a high-level signal, scan(n) is a high-level signal, and comp is a low-level signal, transistors T3, T4, and T6 are in the on state, and the driving transistor DTFT is also in the on state, while the other transistors are in the off state. At this time, the potential Va at node a is Vint, and the potential Vb at node b is ELVDD-|vth|.

[0070] 3. Data writing stage

[0071] Referring to Figures 6(a) and 6(b), when em and comp are both high-level signals and scan(n) is low-level signal, transistor T5 is in the on state, and the driving transistor DTFT is also in the on state, while the other transistors are in the off state. At this time, the potential Va at node a is Vdata, and the potential Vb at node b is (Vdata-Vint)*C1 / (C1+Cst)+ELVDD-|Vth|.

[0072] 4. Luminescence stage

[0073] Referring to Figures 7(a) and 7(b), when em is a low-level signal, comp is a high-level signal, and scan(n) is a high-level signal, transistor T2 is in the on state, and the driving transistor DTFT is also in the on state, while the other transistors are in the off state. At this time, the final DTFT VGS+|vth|=(Vdata-Vint)*C1 / (C1+Cst)+ELVDD-|Vth|-ELVDD+|Vth|=(Vdata-Vint)*C1 / (C1+Cst).

[0074] Based on stages 1 to 4 above, under ideal conditions, i.e., when the charging time for the storage capacitor Cst is sufficiently long, VGS + |Vth| = (Vdata - Vint) * C1 / (C1 + Cst). However, in reality, the charging time for the storage capacitor Cst is not infinitely long, and the ideal value (Vdata - Vint) * C1 / (C1 + Cst) cannot be reached within a finite time. This results in an error α * |Vth| between the actual and ideal values, meaning the actual value is (Vdata - Vint) * C1 / (C1 + Cst) + α * |Vth|. Based on the relationship between current and compensation information |vth|, I = 0.5K(VGS + |vth|). 2It can be seen that there is a positive correlation between current and compensation information |vth|. The longer the charging time, the greater the compensation information. Assuming that the error α*|Vth| remains unchanged, the longer the charging time, the smaller α becomes. This indicates that the pixel circuit has a stronger ability to reduce the influence of Vth on current, eventually causing the error to tend to 0.

[0075] Second, the working process of the second pixel circuit using the 7T1C circuit structure includes:

[0076] 1. Initialization Phase

[0077] Referring to Figures 8(a) and 8(b), when em is a high-level signal, scan(n) is a low-level signal, and scan(n+1) is a high-level signal, transistor T6 is in the on state, and the other transistors are in the off state. At this time, the potential VQ at node Q is Vint. If Vint is equal to elvdd, the storage capacitor Cst can be initialized, i.e., reset, in preparation for subsequent compensation.

[0078] 2. Compensation Phase

[0079] Referring to Figures 9(a) and 9(b), when em is a high-level signal, scan(n) is a high-level signal, and scan(n+1) is a low-level signal, transistors T4, T4, and T7 are turned on, and the driving transistor DTFT is also turned on. The remaining transistors are turned off. At this time, the ideal potential at node Q is VQ = Vdata - |vth|. The anode of the light-emitting diode D is reset to Vint.

[0080] In practical applications, the potential at node Q is related to the charging time. The driving transistor DTFT VGS = Vdata - |vth| + α * |vth|; the longer the compensation time, the smaller α becomes.

[0081] 3. Luminescence stage

[0082] Referring to Figures 10(a) and 10(b), when em is a low-level signal, scan(n) is a high-level signal, and scan(n+1) is a high-level signal, transistor T2 is turned on, and driving transistor DTFT is in the on state, while the other transistors are in the off state. At this time, VGS = Vdata - |vth| - elvdd.

[0083] Based on stages 1 to 3 above, in practical applications, I = 0.5K(VGS + |Vth|). 2 =0.5k(vdata-elvdd) 2 Ideally, the current in the light-emitting diode D is independent of the compensation signal Vth of the offset characteristic of the driving transistor DTFT.

[0084] Based on the analysis of the working process of the first pixel circuit (6T2C) and the second pixel circuit (7T1C), the following differences exist between the two in the compensation process: The 6T2C circuit structure provides the compensation signal Vth through a preset control signal elvdd. At this time, the comp signals of adjacent rows of pixel circuits in the display screen can have overlapping areas, with the effect as follows: Figure 11 As shown. In other words, the 6T2C circuit structure can extend the charging time of the storage capacitor Cst by increasing the overlap time of the low-level signals of adjacent rows of comp signals, thereby ensuring an increase in the compensation signal Vth and improving the current compensation effect of the driving transistor DTFT in the saturation-subthreshold operating state. The 7T1C circuit structure provides the compensation signal Vth through pixel data data. Since the pixel data data of adjacent rows of pixels are different, there cannot be an overlapping area. Therefore, the period of the low-level signal at scan is positively correlated with the row period, and the effect is as follows. Figure 12 As shown. At this point, the current compensation effect can be improved when the driving transistor DTFT is operating in the linear-saturation region.

[0085] Furthermore, since the driving transistor DTFT in the first display area is in the linear-saturation region and the driving transistor DTFT in the second display area is in the saturation-subthreshold region, the compensation for the characteristic shift can be enhanced by adjusting the charging time (or compensation time) of the second pixel circuit (i.e., the 6T2C circuit structure) in the second display area. This will make the brightness difference between the first and second display areas less than the set threshold, i.e., the brightness of the first and second display areas tend to be consistent.

[0086] exist Figures 1-12 Based on the illustrated electronic device, this disclosure also provides a display control method, see [link to relevant documentation]. Figure 13 The method includes:

[0087] In step 131, the current display duration of the display screen is obtained;

[0088] In step 132, based on the preset correspondence between display duration and charging time, a target charging time that matches the current display duration is determined;

[0089] In step 132, the charging time of the storage capacitor in the second pixel circuit is controlled to be the target charging time.

[0090] It should be noted that the current display duration can be counted from when the screen switches from black to light, and the current value read from the timer is the current display duration.

[0091] In this way, by dynamically adjusting the charging time of the stored content in the second display area, the brightness of the first and second display areas can be kept consistent, which is beneficial to improving the viewing experience.

[0092] exist Figures 1-12 Based on the illustrated electronic device, this disclosure also provides a display control method, see [link to relevant documentation]. Figure 14 The method includes:

[0093] In step 141, the current image of the display screen is acquired; the current image is captured when the display screen displays the target image after displaying a preset duration.

[0094] In step 142, when the brightness difference between the first display area and the second display area in the current image exceeds a set threshold, the charging time of the storage capacitor in the second pixel circuit is adjusted until the brightness difference is less than the set threshold.

[0095] It should be noted that the current image on the display screen can be captured using an external camera, such as... Figure 1 The image is captured when the display status is displayed and then stored in a designated location. This way, when the electronic device needs to adjust the display, such as when a user triggers a corresponding operation button, the electronic device can read the image from the designated location as the current image for processing. To ensure optimal adjustment, the time interval between capturing the image using the camera and triggering the operation button should be as short as possible (e.g., less than or equal to 5 minutes).

[0096] In this way, by using the current image on the display screen, the charging time of the stored content in the second display area can be dynamically adjusted, so as to achieve a display effect where the brightness of the first and second display areas is consistent, which is beneficial to improving the viewing experience.
