[0029] 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 in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0030] In related technologies, Long H and Long V technologies are commonly used to achieve wideband display, for example, a scan frequency of 1Hz to 120Hz. Long H technology keeps the number of scan lines constant (i.e., does not add virtual scan lines), but the write time for each line of data varies at different scan frequencies. Long V technology adds virtual scan lines (i.e., display-not-display (Blank) intervals) when switching from a high-frequency to a low-frequency scan frequency to ensure that the write time for each line of data remains consistent across high and low frequency scans. During line scanning, all added virtual scan lines are scanned first, and then all real pixel lines are scanned. Figure 1 As shown. Figure 1 In this context, the EM signal (e.g., EM_0 to EM_n) is the signal that controls the light-emitting stage of the dot-screen timing. During the light-emitting stage, the light-emitting units (e.g., OLED, LED, etc.) in the dot-screen are lit up. The Scan1 signal is the signal that initializes the anode of the light-emitting unit and the gate of the driving transistor. The Scan2 signal is the signal that controls the writing of data signals.

[0031] Both the existing Long H and Long V technologies suffer from screen flickering issues, which negatively impact user experience.

[0032] Figure 2 This is a flowchart illustrating a screen display method according to an exemplary embodiment. This screen display method can be applied to any scenario requiring wideband (e.g., 1Hz-120Hz) display, for example, to low-temperature polycrystalline oxide (LTPO) displays or other types of wideband displays. Figure 2 As shown, the screen display method includes the following steps S11 to S14.

[0033] In step S11, the scanning frequency switching trigger information is obtained.

[0034] In some embodiments, this step can be implemented as follows: First, obtain the screen usage scenario, and then, based on the usage scenario, obtain the scanning frequency switching trigger information.

[0035] Use case refers to the current application scenario of the terminal device, such as gaming scenario (that is, the user is playing a game through the terminal device), music playback scenario (that is, the terminal device is playing music), standby scenario (that is, the terminal device is currently in standby mode), etc.

[0036] If the usage scenario of a terminal device changes, this change in usage scenario becomes the trigger for switching the screen scan frequency. For example, if the screen was previously in a game scenario and then switched to a music playback scenario, this change in usage scenario will trigger a switch in the screen scan frequency.

[0037] In some embodiments, this step can also be implemented by obtaining scan frequency switching trigger information from the scan frequency switching command input by the user. For example, the user can instruct the scan frequency switching command to switch the screen's scan frequency from a first scan frequency to a second scan frequency.

[0038] In step S12, based on the scanning frequency switching trigger information, it is determined that the screen scanning frequency needs to be switched to the first scanning frequency.

[0039] In some embodiments, the terminal device may have a preset correspondence between screen usage scenarios and screen scanning frequencies. For example, a first scanning frequency may be used in a first usage scenario, a second scanning frequency in a second usage scenario, and a third scanning frequency in a third usage scenario. Thus, after obtaining the information about the desired usage scenario carried in the scanning frequency switching trigger information, the device can determine, based on the preset correspondence between usage scenarios and scanning frequencies, that the screen's scanning frequency needs to be switched to the scanning frequency corresponding to the desired usage scenario.

[0040] For example, suppose the terminal device with a wide frequency range display was previously in a game scene, so the screen needs to use a high scanning frequency (e.g., 120Hz) to maintain the image quality and reduce ghosting. Later, if the terminal device enters a usage scenario of playing audio, the screen scanning frequency can be reduced (e.g., using a scanning frequency of 60Hz) to reduce power consumption. Then, the operation of the terminal device starting audio playback becomes the trigger information for switching the screen scanning frequency.

[0041] In some embodiments, if the scan frequency switching trigger information is obtained from a scan frequency switching instruction input by the user, the screen's scan frequency to be switched to which scan frequency can be determined based on the scan frequency switching instruction. For example, if the user instructs in the scan frequency switching instruction to switch the screen's scan frequency from a first scan frequency to a second scan frequency, then based on the scan frequency switching trigger information, it can be determined that the screen's scan frequency needs to be switched to the second scan frequency.

[0042] In step S13, the total number of virtual scan rows required at the first scan frequency is determined.

[0043] Virtual scan line scanning refers to displaying the Blank area. In this case, Scan1 and Scan2 signals are working normally, and the EM signal keeps the screen in the luminous phase, but the luminous units do not emit light. In other words, a virtual scan line is a scan line without any actual displayed content.

[0044] In some embodiments, the total number of virtual scan rows required at the first scan frequency can be determined based on the write duration requirement for each row of data and the first scan frequency.

[0045] For example, if the write time for each line of data is required to be equal across all screen scan frequencies, the total number of virtual scan lines required at the first scan frequency can be determined using the ratio of the highest screen scan frequency to the first scan frequency. In other words, this disclosure first ensures that the write time for each line of data is consistent across all different screen scan frequencies, and then, based on this, determines the total number of virtual scan lines required according to the scan frequency to be switched to.

[0046] Taking a screen with n actual pixel rows and a maximum scan frequency of 120Hz as an example. If the screen scan frequency needs to be switched from 120Hz to 60Hz, then to ensure the write time for each row of data remains consistent with the 120Hz setting, more virtual scan rows need to be added. The total number of added virtual scan rows is n, since 120Hz / 60Hz = 2. This means that at 60Hz, the total number of scan rows needs to reach 2n to meet the requirement of consistent write time for each row of data. Since the actual pixel rows on the screen are n, adding n more virtual scan rows will achieve the total number of scan rows of 2n. If the scan frequency needs to be switched to 30Hz, then to ensure the write time for each row of data remains consistent with the 120Hz setting, the total number of added virtual scan rows is 3n. In other words, the lower the screen scan frequency, the shorter the time required to scan the actual pixel rows, and the more virtual scan rows are needed. Suppose the screen scanning frequency needs to be switched from 30Hz to 60Hz. Since the total number of virtual scan lines is 3n at 30Hz and n at 60Hz, the total number of virtual scan lines needs to be reduced when switching the scanning frequency from 30Hz to 60Hz in order to meet the requirement of consistent writing time for each line of data.

[0047] In step S14, the virtual scan lines and the actual pixel lines of the screen are scanned alternately.

[0048] A real pixel row is a scan row with actual display content. That is, in a real scan row, display pixels (such as light-emitting units) will light up or turn off according to the actual display content.

[0049] Alternating scanning of virtual scan lines and real pixel lines on the screen means that after scanning a number of virtual scan lines, a number of real pixel lines are then scanned, rather than scanning all virtual scan lines first and then starting to scan the real pixel lines. For example, after scanning N virtual scan lines, M real pixel lines are scanned, then I virtual scan lines are scanned, then J real pixel lines are scanned, and so on, until all virtual scan lines and all real pixel lines are scanned. N, M, I, and J can be equal or unequal.

[0050] In some embodiments, virtual scan lines and actual pixel lines of the screen can be scanned alternately in proportion. This can be achieved as follows: First, based on the required write time for each row of data, the number of virtual scan lines corresponding to each actual pixel line is determined. For example, based on the requirement that the write time for each row of data is equal at any scanning frequency, the number of virtual scan lines corresponding to each actual pixel line can be determined using the ratio of the highest scanning frequency to the first scanning frequency of the screen. Taking a screen with n actual pixel lines and a highest scanning frequency of 120Hz as an example, assuming the screen scanning frequency needs to switch from 120Hz to 60Hz, since 120Hz / 60Hz=2, at a scanning frequency of 60Hz, one actual pixel line needs to correspond to one virtual pixel line to meet the requirement of consistent write time for each row of data. Then, after determining the number of virtual scan lines corresponding to each actual pixel line, the virtual scan lines and actual pixel lines can be scanned alternately according to the ratio between the number of actual pixel lines and their corresponding virtual scan lines.

[0051] The following example, using a total of n actual pixel rows and a maximum screen scanning frequency of 120Hz, illustrates how to perform proportional alternating scanning of virtual scan rows and real pixel rows when the screen scanning frequency is switched from 120Hz to 30Hz, from 120Hz to 60Hz, and from 120Hz to 90Hz.

[0052] When the screen scan frequency switches from 120Hz to 30Hz, the requirement that the write time for each line of data must remain consistent across different scan frequencies dictates that at 30Hz, one real pixel row must correspond to three virtual scan rows to ensure that the write time for each line of data remains consistent between 120Hz and 30Hz. Therefore, the row scanning sequence can be as follows: first scan the first three virtual scan rows, then scan the first real pixel row, then scan the fourth to sixth virtual scan rows, then scan the second real pixel row, then scan the seventh to ninth virtual scan rows, then scan the third real pixel row, and so on, completing the proportional alternating scanning of virtual scan rows and real pixel rows. Figure 3 As shown.

[0053] When the screen scan frequency switches from 120Hz to 60Hz, the requirement that the write time for each line of data must remain consistent across different scan frequencies dictates that at 60Hz, one real pixel row must correspond to one virtual scan row to ensure that the write time for each line of data remains consistent between 120Hz and 60Hz. Therefore, the row scanning sequence can be as follows: first scan the first virtual scan row, then scan the first real pixel row, then scan the second virtual scan row, then scan the second real pixel row, then scan the third virtual scan row, then scan the third real pixel row, and so on, completing the proportional alternating scanning of virtual scan rows and real pixel rows. Figure 4 As shown.

[0054] When the screen scan frequency switches from 120Hz to 90Hz, the requirement that the write time for each line of data must remain consistent across different scan frequencies dictates that at 90Hz, three real pixel rows must correspond to one virtual scan row to ensure that the write time for each line of data remains consistent between 120Hz and 90Hz. Therefore, the row scanning sequence can be as follows: first scan the first virtual scan row, then scan the first to third real pixel rows, then scan the second virtual scan row, then scan the fourth to sixth real pixel rows, then scan the third virtual scan row, then scan the seventh to ninth real pixel rows, and so on, completing the proportional alternating scanning of virtual and real pixel rows. Figure 5 As shown.

[0055] By adopting the above technical solution, since the scanning frequency switching trigger information can be obtained, it is determined that the screen scanning frequency needs to be switched to the first scanning frequency based on the scanning frequency switching trigger information. The total number of virtual scanning lines required under the first scanning frequency is determined. Then, the virtual scanning lines and the real pixel lines of the screen are scanned alternately. Through the alternating scanning of virtual scanning lines and real pixel lines, the display blank range is greatly reduced, the screen flickering problem when switching between different scanning frequencies is improved, and the user experience is enhanced.

[0056] Additionally, it should be noted that the above... Figures 3 to 5 The control timing of a screen using Low Temperature Poly-Silicon (LTPS) technology is described as an example. However, those skilled in the art should understand that this disclosure is equally applicable to screens using LTPS technology.

[0057] The control timing of LTPO differs from that of LTPS. For example, in LTPO, while the EM signal is high, the Scan1 and Scan2 signals may be low or high at times. Figure 6 and 7 As shown. Among them, Figure 6 This is a schematic diagram of an LTPO circuit structure according to an exemplary embodiment. Figure 7 This is a control timing diagram of an LTPO circuit according to an exemplary embodiment.

[0058] Although the control timing of LTPO differs from that of LTPS, the alternating scanning strategy between virtual scan lines and real pixel lines on the screen is similar. Taking a screen scan frequency change from 120Hz to 60Hz as an example, for screens using LTPO technology, the alternating scanning still follows a 1:1 ratio between virtual scan lines and real pixel lines. That is, during line scanning, the timing sequence is as follows: first scan the first virtual scan line, then scan the first real pixel line, then scan the second virtual scan line, then scan the second real pixel line, then scan the third virtual scan line, then scan the third real pixel line, and so on, completing the proportional alternating scanning of virtual scan lines and real pixel lines. Figure 8 As shown.

This screen display device can be applied to any scenario requiring wideband display. Figure 9As shown, the screen display device includes: an acquisition module 61, used to acquire scanning frequency switching trigger information; a first determination module 62, used to determine, based on the scanning frequency switching trigger information, that the screen's scanning frequency needs to be switched to a first scanning frequency; a second determination module 63, used to determine the total number of virtual scan lines required at the first scanning frequency; and a scanning module 64, used to alternately scan the virtual scan lines and the screen's actual pixel lines.

[0060] By adopting the above technical solution, since the scanning frequency switching trigger information can be obtained, it is determined that the screen scanning frequency needs to be switched to the first scanning frequency based on the scanning frequency switching trigger information. The total number of virtual scanning lines required under the first scanning frequency is determined. Then, the virtual scanning lines and the real pixel lines of the screen are scanned alternately. Through the alternating scanning of virtual scanning lines and real pixel lines, the display blank range is greatly reduced, the screen flickering problem when switching between different scanning frequencies is improved, and the user experience is enhanced.

[0064] Optionally, the second determining module 63 is used to: based on the requirement that the writing time of each line of data on the screen is equal at any scanning frequency, determine the total number of virtual scan lines required at the first scanning frequency by using the ratio of the highest scanning frequency of the screen to the first scanning frequency.
