[0057] Applicant notices that AMOLED is a display technology that is widely used in the market at present, and is more obvious in mobile phone terminals and wearable terminals. At the same time, the split screen technology is also widely used in large-screen mobile phones and notebook computers. After combining the two technologies, in some products, the two screens after splitting can realize different functions, for example, one screen realizes display function, and the other screen realizes touch function. However, in the current technology, the two screens after splitting do not adopt different refresh frequencies according to their respective functions, which leads to the fact that the screen that does not need high refresh rate consumes more resources, thereby causing unnecessary waste.

[0058] The specific embodiments of the present application are described below through examples:

[0059] As shown in Figure 1 and Figure 2 , the embodiment of the present application provides a display panel, which comprises a display part and a driving part; the display part comprises a first display area, a second display area and a transition part, the transition part is located between the first display area and the second display area; the transition part comprises at least one transition display area; wherein the driving part comprises a GOA circuit and a frequency reduction unit, the GOA circuit is connected with the frequency reduction unit, and the frequency reduction unit is connected with the first display area, the transition display area and the second display area to make the refresh frequency of the first display area, the transition display area and the second display area gradually decrease when displaying. It can be understood that after the display panel is split, the first display area and the second display area are respectively applied to different functions, such as the first display area for displaying video content and the second display area for displaying picture content. In order to reduce the power consumption of the screen after splitting, the frequency reduction unit is connected at the output end of the GOA circuit, so as to perform frequency reduction processing on the screen that does not need high refresh rate, for example, the screen displaying pictures or touch keyboard can reduce the refresh frequency, while the screen displaying video content needs to display more details, and then a higher refresh frequency can be maintained. The present application reduces the power consumption of the screen by controlling the refresh frequency of the different screens after splitting, thereby saving resources. At the same time, considering that there will be a large difference in brightness and chroma between the two screens after frequency reduction processing, which leads to unnatural transition at the junction of the first display area and the second display area. The transition part is arranged between the first display area and the second display area, and the transition part is divided into a plurality of transition display areas, the plurality of transition display areas can be displayed in a step-by-step frequency reduction manner from high to low according to the refresh frequencies of the first display area and the second display area, so that the difference in brightness and chroma is smaller when transitioning from the first display area to the second display area, and at the same time, the transition from high frequency to low frequency in the first display area and the second display area is more natural.

[0060] As shown in Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 9 and Figure 10As shown in the application, the first display area is provided with the first light emitting unit P1, the second display area is provided with the second light emitting unit P2, and the transition part is provided with the third light emitting unit P3; wherein in the split screen display mode, the light emitting frequency of the first light emitting unit P1 when emitting light is greater than the light emitting frequency of the third light emitting unit P3 when emitting light, and the light emitting frequency of the third light emitting unit P3 when emitting light is greater than the light emitting frequency of the second light emitting unit P2 when emitting light. It can be understood that in the split screen display, in order to ensure that the brightness and chrominance difference between the first display area and the second display area is smaller, and the transition is more natural, the corresponding light emitting unit is arranged in each area, so that the refresh frequency of the first display area, the transition part and the second display area when displaying is gradiently decreased from large to small. In some other embodiments of the application, according to the actual use, the refresh frequency of each display area can also be arranged from large to small in the second display area, the transition part and the first display area.

[0061] As shown in the application, Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 9 and Figure 10 As shown in the application, the first display area is provided with the first light emitting unit P1, the second display area is provided with the second light emitting unit P2, and the transition part is provided with the third light emitting unit P3; wherein in the normal display mode, the light emitting frequency of the first light emitting unit P1 when emitting light is equal to the light emitting frequency of the third light emitting unit P3 when emitting light, and the light emitting frequency of the third light emitting unit P3 when emitting light is equal to the light emitting frequency of the second light emitting unit P2 when emitting light. It can be understood that in the split screen display, the refresh frequency of each area needs to be controlled, so as to reduce the brightness and chrominance difference between the first display area and the second display area. But when not split screen, the first display area and the second display area use the same refresh frequency for display, and the refresh frequency of the transition part is the same as that of the first display area and the second display area. So that the display panel can maintain high refresh frequency when not split screen, and avoid display error of different refresh frequency areas when not split screen.

[0062] As shown in the application, Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 8 and Figure 9As shown in the embodiments of the present application, the GOA circuit includes a first drive circuit, a second drive circuit and a third drive circuit, the first drive circuit outputs a first drive signal, the second drive circuit outputs a second drive signal, and the third drive circuit outputs a third drive signal; wherein the first drive signal, the second drive signal and the third drive signal have the same frequency. It can be understood that the first drive signal, the second drive signal and the third drive signal are all high-frequency signals and drive the first light emitting unit P1, the second light emitting unit P2 and the third light emitting unit P3 to emit light. By driving the light emitting units to emit light by the same frequency drive signal, it is ensured that the screen can maintain the same refresh frequency for display when not being split-screened, avoiding display errors caused by different refresh frequencies in different regions.

[0063] As shown in the embodiments of the present application, the GOA circuit includes a first drive circuit, a second drive circuit and a third drive circuit, the first drive circuit outputs a first drive signal, the second drive circuit outputs a second drive signal, and the third drive circuit outputs a third drive signal; wherein the first drive signal, the second drive signal and the third drive signal have the same frequency. It can be understood that the first drive signal, the second drive signal and the third drive signal are all high-frequency signals and drive the first light emitting unit P1, the second light emitting unit P2 and the third light emitting unit P3 to emit light. By driving the light emitting units to emit light by the same frequency drive signal, it is ensured that the screen can maintain the same refresh frequency for display when not being split-screened, avoiding display errors caused by different refresh frequencies in different regions. Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 8 and Figure 9 As shown in the embodiments of the present application, the second drive circuit outputs a fourth drive signal by being connected with the frequency reduction unit D; the third drive circuit outputs a fifth drive signal by being connected with the frequency reduction unit D; wherein the frequency of the first drive signal is greater than the frequencies of the fourth drive signal and the fifth drive signal, and the frequencies of the fourth drive signal and the fifth drive signal are the same; the second drive circuit also outputs a sixth drive signal by being connected with the frequency reduction unit D, and the third drive circuit also outputs a seventh drive signal by being connected with the frequency reduction unit D; the frequency of the fourth drive signal is greater than the frequencies of the sixth drive signal and the seventh drive signal, and the frequencies of the sixth drive signal and the seventh drive signal are the same.

[0064] In the embodiments of the present application, the first display area is by default a high refresh rate area when split-screened, and the second display area is a low refresh frequency area. Therefore, when the screen is split-screened, the refresh frequency of the second light emitting unit P2 is the lowest, and at the same time, the refresh frequency is gradiently decreased. Therefore, the refresh frequency of the third light emitting unit P3 is higher than that of the second light emitting unit P2. As shown in the embodiments of the present application, the refresh frequency of the second light emitting unit P2 in the second display area is 10 Hz, and the refresh frequencies of the third light emitting unit P3 in the transition display area from left to right are 60 Hz and 30 Hz. The output frequencies of the first drive signal are the same and are 120 Hz, and the output frequencies of the fourth drive signal and the fifth drive signal are both 30 Hz. Figures 2 to 4 As shown in the embodiments of the present application, the refresh frequency of the second light emitting unit P2 in the second display area is 10 Hz, and the refresh frequencies of the third light emitting unit P3 in the transition display area from left to right are 60 Hz and 30 Hz. The output frequencies of the first drive signal are the same and are 120 Hz, and the output frequencies of the fourth drive signal and the fifth drive signal are the same and are 10 Hz. Figures 5 to 7 As shown in the embodiments of the present application, the refresh frequency of the second light emitting unit P2 in the second display area is 10 Hz, and the refresh frequencies of the third light emitting unit P3 in the transition display area from left to right are 60 Hz and 30 Hz. The output frequencies of the first drive signal are the same and are 120 Hz, and the output frequencies of the fourth drive signal and the fifth drive signal are the same and are 10 Hz.Figures 8 to 10 As shown in some other embodiments of the present application, the light emitting units in the second display area and the transition display area are driven by the first driving signal, the second driving signal and the third driving signal. The refresh frequency of the second light emitting unit P2 in the second display area is 10 Hz, and the refresh frequency of the third light emitting unit P3 in the transition display area from left to right is 60 Hz and 30 Hz. It can be understood that by controlling the refresh frequency of the first display area, the transition display area and the second display area, the area which does not need to display details can be kept at a small refresh frequency, thereby reducing the power consumption of the screen when split-screen display, and saving power resources.

[0065] As shown in some other embodiments of the present application, the light emitting units in the second display area and the transition display area are driven by the first driving signal, the second driving signal and the third driving signal. The refresh frequency of the second light emitting unit P2 in the second display area is 10 Hz, and the refresh frequency of the third light emitting unit P3 in the transition display area from left to right is 60 Hz and 30 Hz. It can be understood that by controlling the refresh frequency of the first display area, the transition display area and the second display area, the area which does not need to display details can be kept at a small refresh frequency, thereby reducing the power consumption of the screen when split-screen display, and saving power resources. Figure 2 Figure 3 As shown in some other embodiments of the present application, the light emitting units in the second display area and the transition display area are driven by the first driving signal, the second driving signal and the third driving signal. The refresh frequency of the second light emitting unit P2 in the second display area is 10 Hz, and the refresh frequency of the third light emitting unit P3 in the transition display area from left to right is 60 Hz and 30 Hz. It can be understood that by controlling the refresh frequency of the first display area, the transition display area and the second display area, the area which does not need to display details can be kept at a small refresh frequency, thereby reducing the power consumption of the screen when split-screen display, and saving power resources. Figure 4 As shown in some other embodiments of the present application, the light emitting units in the second display area and the transition display area are driven by the first driving signal, the second driving signal and the third driving signal. The refresh frequency of the second light emitting unit P2 in the second display area is 10 Hz, and the refresh frequency of the third light emitting unit P3 in the transition display area from left to right is 60 Hz and 30 Hz. It can be understood that by controlling the refresh frequency of the first display area, the transition display area and the second display area, the area which does not need to display details can be kept at a small refresh frequency, thereby reducing the power consumption of the screen when split-screen display, and saving power resources.

[0066] Figure 2 As shown in some other embodiments of the present application, the light emitting units in the second display area and the transition display area are driven by the first driving signal, the second driving signal and the third driving signal. The refresh frequency of the second light emitting unit P2 in the second display area is 10 Hz, and the refresh frequency of the third light emitting unit P3 in the transition display area from left to right is 60 Hz and 30 Hz. It can be understood that by controlling the refresh frequency of the first display area, the transition display area and the second display area, the area which does not need to display details can be kept at a small refresh frequency, thereby reducing the power consumption of the screen when split-screen display, and saving power resources. Figure 3 Figure 4 ​​​As shown, the first light emitting unit P1 in the first display area is directly driven by the first driving signal, the second driving signal and the third driving signal at 120 Hz, so the refresh frequency of the first light emitting unit P1 is 120 Hz. The left transition display area is first directly connected and driven by the first driving signal at 120 Hz, and then the second driving signal at 120 Hz and the third driving signal at 120 Hz are input to the left transition display area after being reduced to 60 Hz by the 60 Hz reduction unit, so the refresh frequency of the left transition display area is 60 Hz; and the right transition display area is first directly connected and driven by the first driving signal at 120 Hz, and then directly driven by the fourth driving signal at 30 Hz and the fifth driving signal at 30 Hz, so the refresh frequency of the right transition display area is 30 Hz. The second display area is first directly connected and driven by the first driving signal at 120 Hz, and then driven by the fourth driving signal at 30 Hz and the fifth driving signal at 30 Hz after being reduced to 10 Hz by the 10 Hz reduction unit, so the refresh frequency of the second display area is 10 Hz. It should be noted that the refresh frequency of the first display area 120 Hz in the present application is only for ease of illustration, and in actual application, the refresh frequency of the first display area can be higher than 120 Hz, such as 144 Hz, 240 Hz, or lower than 120 Hz, such as 85 Hz, 60 Hz, etc. The refresh frequency of the transition display area and the second display area is determined by the refresh frequency of the first display area, and generally, the refresh frequency of the transition display area and the second display area is selected from the divisors of the refresh frequency of the first display area. At the same time, the transition display area can also have multiple, such as 3, 4, 8 or 12 or even more. It can be known that the more the number of transition display areas, the more natural the display panel transitions, and the smaller the chroma difference and luminance difference between adjacent display areas. In the embodiment of the present application, the reduction unit D is arranged outside the display part, which can ensure the integrity of the display part, improve the luminance of the first display area, the transition display area and the second display area in the display part, and reduce the space arrangement pressure of the display part.

It can be understood that in this embodiment, the first driving signal is connected with and drives the first light emitting unit P1, the second light emitting unit P2 and the third light emitting unit P3, the second driving signal and the third driving signal are connected to the third light emitting unit P3 after frequency reduction through the frequency reduction unit, at the same time, the first driving signal, the sixth driving signal and the seventh driving signal are directly connected with the second light emitting unit P2, at this time, the first driving signal is a high frequency signal, the sixth driving signal and the seventh driving signal are both low frequency signals, and the sixth driving signal and the seventh driving signal can be respectively connected with a plurality of frequency reduction units D after frequency reduction through the second driving signal or the third driving signal. The embodiment of the present application embeds the frequency reduction unit D in the display part, which can reduce the frame outside the display panel, so as to make the frame of the display device more narrow, thereby improving the viewing property.

[0068] As Figure 5 , Figure 6 and Figure 7As shown, in the embodiment of the present application, the transition display area has multiple, and the frequency reduction unit D is located between the first display area and the transition display area and between multiple transition display areas; the first driving signal is input to the first light emitting unit P1, the second light emitting unit P2 and the third light emitting unit P3 respectively; the second driving signal and the third driving signal are input to the first light emitting unit P1, and are input to the second light emitting unit P2 and the third light emitting unit P3 through the frequency reduction unit D respectively; the sixth driving signal and the seventh driving signal are input to the second light emitting unit P2. It can be understood that in this embodiment, the first driving signal provides 120Hz driving signal for the first light emitting unit P1, the second light emitting unit P2 and the third light emitting unit P3. While the 120Hz second driving signal and the 120Hz third driving signal are first input to the first light emitting unit P1, and then the 120Hz second driving signal and the 120Hz third driving signal are input to the third light emitting unit P3 in the left transition display area after being reduced by the 60Hz frequency reduction unit D, and then the 120Hz second driving signal and the 120Hz third driving signal are input to the third light emitting unit P3 in the right transition display area after being reduced by the 30Hz frequency reduction unit D. While the second light emitting unit P2 in the second display area is directly driven by the 120Hz first driving signal, the 10Hz sixth driving signal and the 10Hz seventh driving signal. The embodiment of the present application embeds the frequency reduction unit D in the display part, which can reduce the frame outside the display panel, so as to make the frame of the display device more narrow, thereby improving the viewing property.

[0069] As Figure 8 , Figure 9 and Figure 10As shown, in the embodiment of the present application, the transition display area has multiple, the frequency reduction unit D is located between the first display area and the transition display area, between multiple transition display areas and between multiple transition display areas and the second display area; the first driving signal is input to the first light emitting unit P1, the second light emitting unit P2 and the third light emitting unit P3 respectively; the second driving signal and the third driving signal are input to the first light emitting unit P1, and are input to the second light emitting unit P2 and the third light emitting unit P3 through one or more frequency reduction units D respectively. It can be understood that in this embodiment, the first driving signal provides 120Hz driving signal for the first light emitting unit P1, the second light emitting unit P2 and the third light emitting unit P3. The second driving signal and the third driving signal provide 120Hz driving signal for the first light emitting unit P1.

[0071] As shown in Figure 11 And Figure 12As shown, the frequency reduction unit D is composed of a PMOS or NMOS TFT, the frequency reduction unit D includes an input end and an output end, the input end inputs a high frequency signal, the output end outputs a corresponding low frequency signal, and the frequency reduction unit D is controlled by the CLK signal output by the IC. In the embodiment of the present application, the input end of the frequency reduction unit D is connected to the second driving signal or the third driving signal, and the output end of the frequency reduction unit D is connected to the second light emitting unit P2 or the third light emitting unit P3. In addition, a plurality of frequency reduction units D can be connected in series with each other to reduce the frequency of a high frequency signal multiple times to obtain a low frequency signal. The frequency of the CLK signal is selected according to the frequencies of the high frequency signal and the low frequency signal. When the frequency of the high frequency signal is 120 Hz and the required low frequency signal is 60 Hz, the input CLK signal is 2 Hz; if the required low frequency signal is 30 Hz, the input CLK signal is 4 Hz, that is, the frequency of the high frequency signal / the frequency of the CLK signal = the frequency of the low frequency signal.

The light emitting unit in the embodiment of the present application is the RGB pixel point. As shown in Figure 16 Figure 17 and Figure 18 , they are three circuits for controlling the light emitting unit to emit light. The light emitting unit is controlled to emit light through the three GOA signals EM, Pscan and Nscan and VDD, and the circuit needs to meet the following conditions when working: in the path from VDD to VSS, the frequency of the TFT controlled by the GOA signal (EM or EM1) cannot be converted or reduced to below 60 Hz; the TFT input by Data to T2 and T7 for Vi_Ano reset cannot be driven by the same signal; when the GOA signal is reduced in frequency, the driving frequency of the TFT of T7 cannot be reduced; except for T5 / T6 / T7, the driving frequency of the TFT controlled by other GOA signals decreases with the decrease of the display frequency. When connecting the circuit, the output end Out of the first driving circuit, the second driving circuit or the third driving circuit in Figures 13 to 15 is connected to the corresponding name in Figures 16 to 18 , for example, the output end Out of the first driving circuit EM is connected to the EM end of the pixel circuit, and the output end Out of the second driving circuit Nscan is connected to the Nscan end of the pixel circuit. It should be noted that when the driving signal output by the driving circuit needs to be reduced in frequency, a frequency reduction unit D needs to be connected between the driving circuit and the pixel circuit, at this time, the output end Out of the second driving circuit Nscan is connected to the input end in of the frequency reduction unit D, and the output end Out of the frequency reduction unit D is connected to the Nscan end of the pixel circuit. ​
