Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a display panel, a display device, and a processing method. Background Art

[0002] Liquid crystal display (LCD) panels, as a highly popular display technology, are widely used in all aspects of daily life and have garnered widespread attention. However, LCD panels face a significant challenge: low-temperature environments can lead to liquid crystal precipitation and slow response times, hindering their development. Therefore, addressing these issues has become a key concern for those skilled in the art. Summary of the Invention

[0003] In view of this, the present application provides a display panel, a display device, and a processing method, the solutions are as follows:

[0004] A display panel, comprising:

[0005] A first substrate and a second substrate are arranged opposite to each other, wherein the first substrate is a TFT substrate and the second substrate is a color filter substrate;

[0006] a liquid crystal layer located between the first substrate and the second substrate;

[0007] a first electrode layer located on a side of the first substrate facing the second substrate, and a second electrode layer located on a side of the second substrate facing the first substrate;

[0008] The first electrode layer inputs a driving signal, and the first electrode layer and the second electrode layer implement a first function based on the driving signal. The first electrode layer also implements a second function based on the driving signal. The first function is to drive the liquid crystal in the liquid crystal layer to deflect, and the second function is to heat the liquid crystal layer to a preset temperature based on the ambient temperature of the display panel.

[0009] Compared with the related art, the technical solution of this application has the following beneficial effects:

[0010] The display panel includes: a first substrate and a second substrate arranged opposite to each other, a liquid crystal layer located between the first substrate and the second substrate, and a first electrode layer located on the side of the first substrate facing the second substrate, and a second electrode layer located on the side of the second substrate facing the first substrate. The first electrode layer and the second electrode layer can realize a first function and a second function based on a driving signal, wherein the first function is to drive the liquid crystal in the liquid crystal layer to deflect, and the second function is to heat the liquid crystal layer to a preset temperature based on the ambient temperature of the display panel. Thus, while realizing the display function, the display panel can also heat the liquid crystal layer through the first electrode layer and the second electrode layer when the ambient temperature of the environment in which it is located is low. Therefore, even if the ambient temperature of the environment in which the display panel is located is low, the liquid crystal layer can be kept at an appropriate temperature through the first electrode layer and the second electrode layer, thereby making the temperature of the liquid crystal layer unaffected by the ambient temperature, thereby suppressing problems such as liquid crystal precipitation and slow response speed caused by the low ambient temperature of the environment in which the display panel is located. In addition, it can be seen from the above that the display panel can achieve heating of the liquid crystal layer through its existing structure, so that the display panel can achieve heating of the liquid crystal layer, but it will not cause major changes in its structure. Only adaptive changes are required for the first electrode layer and the second electrode layer, and there is no requirement for other components except the first electrode and the second electrode. It can be applied to most liquid crystal display panels and is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0029] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0030] As described in the background technology section, a liquid crystal display panel may face problems such as liquid crystal precipitation and high liquid crystal rotation viscosity under low temperature conditions, resulting in slow response speed.

[0031] Based on this, the present application provides a display panel, such as Figure 1 As shown, Figure 1 This is a schematic structural diagram of a display panel provided in this application, which includes:

[0032] A first substrate 102 and a second substrate 104 are disposed opposite each other. The first substrate 102 may be a TFT substrate, and the second substrate 104 may be a color filter substrate. It should be noted that the structures and operating principles of TFT and color filter substrates are well known to those skilled in the art and will not be described in detail here.

[0033] The liquid crystal layer 200 is located between the first substrate 102 and the second substrate 104 .

[0034] A first electrode layer 302 is located on the side of the first substrate 102 facing the second substrate 104, or in other words, the first electrode layer 302 is located on the side of the first substrate 12 facing the liquid crystal layer 200. A second electrode layer 304 is located on the side of the second substrate 104 facing the first substrate 102, or in other words, the second electrode layer 304 is located on the side of the second substrate 104 facing the liquid crystal layer 200.

[0035] The first electrode layer 302 can input a driving signal so that the first electrode layer 302 and the second electrode layer 304 can realize a first function based on the driving signal, and the first electrode layer 302 can realize a second function based on the driving signal. The first function is to drive the liquid crystal in the liquid crystal layer 200 to deflect, and the second function is to heat the liquid crystal layer 200 to a preset temperature based on the ambient temperature of the display panel.

[0036] As can be seen from the above, the display panel can not only drive the deflection of the liquid crystal in the liquid crystal layer 200 based on the driving signal through the first electrode layer 302 and the second electrode layer 304 to achieve the display function, but also heat the liquid crystal layer 200 based on the ambient temperature of the display panel's environment through the first electrode layer 302 based on the driving signal. Thus, while the display panel achieves the display function, it can also raise the temperature of the liquid crystal layer 200 based on the driving signal through the first electrode layer 302 when the ambient temperature of the environment in which it is located is low, or in other words, keep the liquid crystal layer 200 warm, so that the temperature of the liquid crystal layer 200 is higher than the ambient temperature, thereby preventing problems such as liquid crystal precipitation and slow response speed caused by the low ambient temperature of the display panel's environment. In other words, when the ambient temperature of the environment in which the display panel is located is low, the display panel can heat up the liquid crystal layer 200 based on the driving signal through the first electrode layer 302, or keep the liquid crystal layer 200 warm, thereby suppressing the influence of the ambient temperature of the environment in which the display panel is located on the temperature of the liquid crystal layer 200. That is, even if the ambient temperature of the environment in which the display panel is located is low, the liquid crystal layer 200 can be kept at a suitable temperature based on the driving signal through the first electrode layer 302, and the temperature of the liquid crystal layer 200 is not affected by the ambient temperature, thereby suppressing problems such as liquid crystal precipitation and slow response speed caused by the low ambient temperature of the environment in which the display panel is located.

[0037] Furthermore, it is known that the display panel can not only drive the deflection of the liquid crystals in the liquid crystal layer 200 through the first electrode layer 302 and the second electrode layer 304 to achieve the display function, but can also heat the liquid crystal layer 200 based on the ambient temperature of the display panel's environment through the first electrode layer 302. Furthermore, the first electrode layer 302 and the second electrode layer 304 are inherent structures of the display panel. Therefore, the display panel can heat the liquid crystal layer 200 through its inherent structure, thereby achieving heating of the liquid crystal layer 200 without significantly altering its structure. Only the first electrode layer 302 and the second electrode layer 304 need to be modified accordingly, and no other components other than the first electrode 302 and the second electrode layer 304 are required. Therefore, the display panel is applicable to most liquid crystal display panels and has high practicality.

[0038] In one embodiment of the present application, Figure 2 As shown, Figure 2This is a schematic diagram of the electrical connection of the first electrode layer 302 in a display panel provided in the present application, wherein the above-mentioned drive signal includes a first drive signal, and the first drive signal includes a first voltage signal D12 and a second voltage signal D14. The voltage values of the first voltage signal D12 and the second voltage signal D14 are the same, and there is a preset phase difference between the first voltage signal D12 and the second voltage signal D14, and the value of the preset phase difference is greater than 0. It should be noted that the above-mentioned preset phase difference is the phase difference between the first voltage signal D12 and the second voltage signal D14 in the same pulse period of the first voltage signal D12 and the second voltage signal D14, that is, the above-mentioned preset phase difference is the phase difference between the i-th pulse period of the first voltage signal D12 and the i-th pulse period of the second voltage signal D14, i≥1.

[0039] It should also be noted that the frequency of the first voltage signal D12 and the frequency of the second voltage signal D14 can be the same, or the frequency of the first voltage signal D12 and the frequency of the second voltage signal D14 can be different. Figure 3 As shown, if the frequency of the first voltage signal D12 and the frequency of the second voltage signal D14 are the same, then the preset phase difference between the first voltage signal D12 and the second voltage signal D14 can be generated by the phase shift between the pulse input moment of the first voltage signal D12 and the pulse input moment of the second voltage signal D14, that is, the above-mentioned preset phase difference can include the phase difference between the pulse input moment of the first voltage signal D12 and the pulse input moment of the second voltage signal D14 in the same pulse cycle. If the frequency of the first voltage signal D12 and the frequency of the second voltage signal D12 are different, the preset phase difference between the first voltage signal D12 and the second voltage signal D14 can be generated by the phase shift between the pulse input moment of the first voltage signal D12 and the pulse input moment of the second voltage signal D14 in the same pulse cycle, and can also be generated by the different frequencies of the first voltage signal D12 and the second voltage signal D12, that is, the above-mentioned preset phase difference can include the phase difference caused by the different frequencies of the first voltage signal D12 and the second voltage signal D12 (such as Figure 4 As shown), or the preset phase difference may include the phase difference between the pulse input moment of the first voltage signal D12 and the pulse input moment of the second voltage signal D14, and the phase difference caused by the difference in frequency between the first voltage signal D12 and the second voltage signal D14 (as shown). Figure 5 shown).

[0040] One end of the first electrode layer 302 is input with the first voltage signal D12, and the other end of the first electrode layer 302 is input with the second voltage signal D14. The first electrode layer 302 and the second electrode layer 304 can implement the first function based on the portion of the first drive signal excluding the preset phase difference, while the first electrode layer 302 can implement the second function based on the preset phase difference. It should be noted that the one end and the other end of the first electrode layer 302 can be opposite ends of the first electrode layer 302, for example, the one end and the other end of the first electrode layer 302 can be opposite ends along the extension direction of the first electrode layer 302.

[0041] Regarding the first electrode layer 30, the second function is achieved based on the preset phase difference. Since the first voltage signal D12 and the second voltage signal D14 have a preset phase difference greater than zero, that is, there is a phase difference between the first voltage signal D12 and the second voltage signal D14. Furthermore, since the first voltage signal D12 is input to one end of the first electrode layer 302 and the second voltage signal D14 is input to the first electrode layer 302, that is, the first voltage signal D12 and the second voltage signal D14, which have a phase difference, are respectively input to the two ends of the first electrode layer 302, a voltage difference is generated between the two opposite ends of the first electrode layer 302 due to the phase difference between the first voltage signal D12 and the second voltage signal D14. This can generate a current between the two ends of the first electrode layer 302. Since current generates heat when flowing through a conductor with resistance, the current generated between the two ends of the first electrode layer 302 causes the first electrode layer 302 to generate heat due to the generated current, thereby heating the liquid crystal layer 200. The first electrode layer 302 and the second electrode layer 304 can realize the first function based on the part of the first driving signal except the preset phase difference, that is, realize liquid crystal display based on the voltage signal provided by the first electrode layer 302 and the second electrode layer 304 to the liquid crystal layer 200. This is well known to those skilled in the art and will not be repeated here.

[0042] It should be noted that a voltage difference is generated at both ends of the first electrode layer 302 due to the phase difference between the first voltage signal D12 and the second voltage signal D14. Specifically, although the voltage values of the first voltage signal D12 and the second voltage signal D14 are the same, according to Figure 3 and Figure 4 It can be seen that when there is a phase difference between the first voltage signal D12 and the second voltage signal D14, during the time period corresponding to the phase difference, that is, during the phase difference maintenance period, the voltages of the first voltage signal D12 and the second voltage signal D14 are not equal, and thus a voltage difference will be generated at both ends of the first electrode layer 302 due to the phase difference between the first voltage signal D12 and the second voltage signal D14.

[0043] In one embodiment of the present application, Figure 6As shown, Figure 6 This application provides an electrical connection diagram of the first electrode layer 302 in a display panel. The driving signal also includes a second driving signal. The second driving signal includes a third voltage signal D22 and a fourth voltage signal D24. The third voltage signal D22 and the fourth voltage signal D24 have the same voltage value and the same phase.

[0044] One end of the first electrode layer 302 receives the third voltage signal D22, and the other end of the first electrode layer 302 receives the fourth voltage signal D24. The first electrode layer 302 and the second electrode layer 304 can implement the first function based on the second drive signal. The second drive signal is not transmitted to the first electrode layer 302 and the second electrode layer 304 simultaneously with the first drive signal. That is, the first electrode layer 302 does not receive both the first drive signal and the second drive signal simultaneously.

[0045] Based on the above, it can be seen that when the ambient temperature of the display panel does not cause problems such as liquid crystal precipitation in the liquid crystal layer 200 and slow response speed, that is, when the ambient temperature of the display panel is suitable, the liquid crystal layer 200 does not need to be heated, or the liquid crystal layer 200 in the display panel is already at a suitable temperature and does not need to be further heated. Therefore, there is no need for the voltage signals input across the first electrode layer 302 to have a phase difference. Therefore, the above-mentioned drive signal also includes a second drive signal, and the third voltage signal D22 and the fourth voltage signal D24 in the second drive signal have the same voltage value and the same phase. When heating of the liquid crystal layer 200 is not required, they can be transmitted to the two ends of the first electrode layer 302 respectively to achieve liquid crystal display, that is, to achieve the first function.

[0046] In one embodiment of the present application, Figure 2 and Figure 6 As shown, the display panel further includes a first voltage driving unit 306 and a second voltage driving unit 308. The first voltage driving unit 306 is electrically connected to one end of the first electrode layer 302 and is configured to generate a first voltage signal D12 and a third voltage signal D22, and transmit the first voltage signal D12 and the third voltage signal D22 to the first electrode layer 302 via the end of the first electrode layer 302 electrically connected thereto, i.e., input the first voltage signal D12 and the third voltage signal D22 to the one end of the first electrode layer 302. The second voltage driving unit 308 is electrically connected to the other end of the first electrode layer 302 and is configured to generate a second voltage signal D14 and a fourth voltage signal D24, and transmit the second voltage signal D14 and the fourth voltage signal D24 to the second electrode layer 304 via the end of the first electrode layer 302 electrically connected thereto, i.e., input the second voltage signal D14 and the fourth voltage signal D24 to the other end of the first electrode layer 302.

[0047] As can be seen from the above, the display panel includes a first voltage driving unit 306 and a second voltage driving unit 308, each of which provides voltage signals to opposite ends of the first electrode layer 302. That is, in this embodiment, the display panel includes separate first and second voltage driving units 306 and 308, each of which provides voltage signals to opposite ends of the first electrode layer 302. This allows the display panel to flexibly adjust the phase difference between the voltage signals input to the opposite ends of the first electrode layer 302 when the liquid crystal layer 200 needs to be heated, thereby achieving precise heating of the liquid crystal layer 200 and preventing insufficient or overheating of the liquid crystal layer 200. It should be noted that, as previously mentioned, heating of the liquid crystal layer 200 can be achieved when there is a phase difference between the first and second voltage signals D12 and D14. Thus, by controlling the phase difference between the first and second voltage signals D12 and D14, the heating time of the liquid crystal layer 200 can be controlled, thereby controlling the degree of heating of the liquid crystal layer 200 and achieving precise heating of the liquid crystal layer 200.

[0048] In one embodiment of the present application, Figure 7 As shown, Figure 7 This is a schematic structural diagram of a display panel provided in the present application. Along a first direction, the first electrode layer 302 may include at least one first electrode unit 1 arranged in sequence, and the second electrode layer 304 may include at least one second electrode unit 2 arranged in sequence. That is, the first electrode layer 302 may include at least one first electrode unit 1 arranged in sequence along the first direction, and the second electrode layer 304 may include at least one second electrode unit 2 arranged in sequence along the first direction. The first electrode unit 1 and the second electrode unit 2 correspond one to one. The first direction is parallel to the plane where the display panel is located. Since the plane where the first substrate 102, the second substrate 104, the first electrode layer 302, and the second electrode layer 304 are parallel to each other and are the plane where the display panel is located, the first direction is also parallel to the plane where the first substrate 102, the second substrate 104, the first electrode layer 302, and the second electrode layer 304 are located. It should be noted that the second electrode layer 304 is a common electrode in the shape of a full-surface electrode. That is, the above-mentioned second electrode layer 304 includes second electrode units 2 corresponding one-to-one to the first electrode units 1, which means that the second electrode layer 304 is divided into areas corresponding one-to-one to the first electrode units 1 based on the first electrode units 1.

[0049] The liquid crystal layer 200 includes a liquid crystal cell 202 located between the first electrode unit 1 and the second electrode unit 2. The liquid crystal cell 202 corresponds one-to-one with the first electrode unit 1 and the second electrode unit 2. That is, the liquid crystal layer 200 includes the liquid crystal cell 202 located between the first electrode unit 1 and the second electrode unit 2. The first electrode unit 1 and the second electrode unit 2 can cooperate to control the deflection of the liquid crystal in the liquid crystal cell 202 and heat the liquid crystal cell 202.

[0050] One end of each of the at least one first electrode unit 1 is electrically connected to the first voltage driving unit 306, receiving a first voltage signal D12 and a third voltage signal D22. The other end of each first electrode unit 1 is electrically connected to the second voltage driving unit 308, receiving a second voltage signal D14 and a fourth voltage signal D24. The first electrode unit 1 and the second electrode unit 2 implement a first function based on the first drive signal or the second drive signal, controlling the deflection of the liquid crystal in the liquid crystal unit 202. The first electrode unit 1 implements a second function based on the first drive signal, heating the liquid crystal layer 200 to a predetermined temperature.

[0051] As can be seen from the above, along the first direction, that is, along the same direction parallel to the plane of the first electrode layer 302 and the second electrode layer 304, the first electrode layer 302 includes at least one first electrode unit 1, and the second electrode layer 304 includes at least one second electrode unit 2. The first electrode unit 1 and the second electrode unit 2 have a one-to-one correspondence and correspond to different regions of the liquid crystal layer 200 along the first direction. In other words, different regions of the liquid crystal layer 200 can be controlled by the overall electrode structure consisting of the first electrode unit 1 and the corresponding second electrode unit 2. That is, different regions of the liquid crystal layer 200 along the first direction can be controlled by the corresponding first electrode unit 1 and second electrode unit 2, thus achieving zoned control of the liquid crystal layer 200.

[0052] In addition, according to Figure 2 and Figure 3 It can be seen that the phase difference between the first voltage signal D12 and the second voltage signal D14 is smaller than the pulse width of the first voltage signal D12 and the second voltage signal D14, and the frequency at which the first voltage signal D12 and the second voltage signal D14 realize the display function is relatively high. Therefore, the phase difference between the first voltage signal D12 and the second voltage signal D14 is extremely small relative to the display frequency, and the impact on the display effect is also minimal, and does not affect the normal operation of the display panel.

[0053] Based on the above, the liquid crystal layer 200 is divided into different areas along the first direction based on at least one first electrode unit 1 in the first electrode layer 302, thereby realizing partition control of the liquid crystal layer 200, and when the liquid crystal layer 200 is heated, differentiated control of different areas of the liquid crystal layer 200 can also be realized.

[0054] For example, the phase differences between the first voltage signal D12 and the second voltage signal D14 inputted by the first electrode unit 1 corresponding to different regions of the liquid crystal layer 200 along the first direction can be the same, that is, the degree of heating of each region of the liquid crystal layer 200 can be the same; or the phase differences between the first voltage signal D12 and the second voltage signal D14 inputted by the first electrode unit 1 corresponding to different regions of the liquid crystal layer 200 along the first direction can be different, that is, the degree of heating of each region of the liquid crystal layer 200 can be different; or the phase differences between the first voltage signal D12 and the second voltage signal D14 inputted by the first electrode unit 1 corresponding to some regions of the liquid crystal layer 200 along the first direction can be the same, and the phase differences between the first voltage signal D12 and the second voltage signal D14 inputted by the first electrode unit 1 corresponding to other regions can be different, that is, the degree of heating of some regions of the liquid crystal layer 200 is the same, while the degree of heating of other regions is different. Thus, the display panel can control the heating of different regions of the liquid crystal layer 200 based on the requirements of the environment or the needs of the use process to match more application scenarios.

[0055] It should be noted that the phase difference between the first voltage signal D12 and the second voltage signal D14 input by the first electrode unit 1 corresponding to different areas of the above-mentioned liquid crystal layer 200 along the first direction can be achieved by controlling the time difference between the pulse input moment of the first voltage signal 12 and the pulse input moment of the second voltage signal D14.

[0056] In one embodiment of the present application, Figure 8 As shown, Figure 8 A schematic structural diagram of a display panel provided in the present application, wherein along the second direction, the first electrode unit 1 includes a plurality of first electrodes 12 arranged in sequence, and the plurality of first electrodes 12 are electrically connected in sequence, and the second electrode unit 2 includes a plurality of second electrodes 22 arranged in sequence, and the first electrodes 12 and the second electrodes 22 correspond one to one. The second direction is parallel to the plane where the display panel is located, wherein the second direction can be parallel to the first direction, or the second direction can be the same as the first direction. It should be noted that the second electrode layer 304 is known to be a common electrode for the entire surface, so that the second electrode unit 2 includes a second electrode 22 opposite to the first electrode 12, which means that the second electrode unit 2 is divided into an area opposite to the first electrode 12 based on the first electrode 12.

[0057] The plurality of first electrodes 12 and the plurality of second electrodes 22 control the deflection of the liquid crystal corresponding to each of the first electrodes 12 and the second electrodes 22 in the liquid crystal layer 200 based on the first drive signal and the second drive signal, thereby achieving a 2D display mode and a 3D display mode. It should be noted that the number of first electrodes 12 in the first electrode unit 1 can be 16, and accordingly, the number of second electrodes 22 in the second electrode unit 2 can also be 16, but this is not limited in this application and will be determined based on specific circumstances.

[0058] Based on the above, it can be seen that the first electrode unit 1 may include multiple first electrodes 12, and the second electrode unit 2 may include multiple second electrodes 22 corresponding to the multiple first electrodes 12, and the first electrodes 12 and the corresponding second electrodes 22 can control the rotation of the liquid crystal located between the two in the liquid crystal layer 200 to achieve a 2D display mode or a 3D display mode, that is, the display panel realizes a 2D display function or a 3D display function, and can be applied to more application scenarios. It should be noted that if the first electrode 12 and the corresponding second electrode 22 control the portion of the liquid crystal layer 200 located between the two to achieve a 3D display, such as Figure 9 As shown, the liquid crystal layer 200 can be deflected by the first voltage signal D12 and the second voltage signal D14 provided by the first electrode 12 and the second electrode 22, forming a rod prism (LC) equivalent structure, and having the optical function of a rod prism to achieve 3D display. It should be noted that the thickness of the first substrate 102 and the second substrate 104 can be 0.5 mm, and the thickness d of the liquid crystal layer 200 can be 100 μm. That is, the thickness of the rod prism equivalent structure formed by the liquid crystal deflection during 3D display can be 100 μm. In addition, the width W of the rod prism equivalent structure can be the distance between two adjacent electrode units (first electrode unit 1 or second electrode unit 2) along the first direction.

[0059] In addition, since the multiple first electrodes 12 are electrically connected in sequence, the multiple first electrodes 12 in each first electrode unit 1 can share a signal transmission port, thereby simplifying the number of signal transmission ports and the arrangement of signal transmission ports, thereby simplifying the structure of the display panel.

[0060] It should be noted that, since the multiple first electrodes 12 in the first electrode unit 1 can share a single signal transmission port, it is relatively easy to make the phase difference of the voltage signals input to the opposite ends of each first electrode 12 in the same first electrode unit 1 equal, that is, the heating degree of the liquid crystal layer 200 by each first electrode 12 in the same first electrode unit 1 is the same, that is, the degree of heating of the liquid crystal layer 200 at each location between the first electrode unit 1 and the second electrode unit 2 can be the same, thereby simplifying the design of the heating program of the liquid crystal layer 200 by the first electrode layer 302 and the second electrode layer 304, and suppressing excessive occupation of chip functions. However, this application is not limited to this. In other embodiments of the application, in order to achieve refined control of the heating of the liquid crystal layer 200, the phase difference input to the opposite ends of each first electrode 12 in the same first electrode unit 1 can also be unequal, or the phase difference can be equal in some parts and equal in other parts, depending on the specific circumstances.

[0061] In another embodiment of the present application, Figure 10 As shown, Figure 10 The present application provides an electrical connection intention for the first electrode layer in a display panel, which further includes a third voltage driving unit 310 and a phase shifting unit 312. The third voltage driving unit 310 is electrically connected to one end of the first electrode layer 302, and is also electrically connected to the other end of the first electrode layer 302 through the phase shifting unit 312.

[0062] The third voltage driving unit 310 is configured to generate a first voltage signal D12, transmit the first voltage signal D12 to an end of the first electrode layer 302 electrically connected thereto, and further transmit the first voltage signal D12 to the phase shifting unit 312. The phase shifting unit 312 generates a second voltage signal D14 based on the first voltage signal D12, and transmits the second voltage signal D14 to an end of the first electrode layer 302 electrically connected thereto. Alternatively, the third voltage driving unit 310 is configured to generate a third voltage signal D22, transmit the third voltage signal D22 to an end of the first electrode layer 302 electrically connected thereto, and further transmit the third voltage signal D22 to the phase shifting unit 312. The phase shifting unit 312 generates a fourth voltage signal D24 based on the third voltage signal D22, and transmits the fourth voltage signal D24 to an end of the first electrode layer 302 electrically connected thereto. That is, when the liquid crystal layer 200 needs to be heated, that is, when the first electrode layer 302 needs to heat the liquid crystal layer 200, the phase shifter 312 phase-shifts the voltage signal generated by the third voltage driving unit 310, so that a phase difference exists between the voltage signals input to opposite ends of the first electrode layer 302. When the liquid crystal layer 200 does not need to be heated, the phase shifter 312 does not phase-shift the voltage signal generated by the third voltage driving unit 310. It can also be understood that the phase shift of the phase shifter 312 is 0 at this time, so that there is no phase difference between the voltage signals input to opposite ends of the first electrode layer 302.

[0063] As can be seen from the above, the difference between this embodiment and the above-mentioned embodiment is that the phase difference between the voltage signals input to the opposite ends of the first electrode layer 302 is achieved by the phase shifting unit 312 in this embodiment, rather than by two separate voltage driving units. Because the second voltage signal D14 is generated based on the first voltage signal D12 by the phase shifting unit 312 in this embodiment, compared to being generated separately by two separate first voltage driving units 306 and second voltage driving units 308, the first voltage signal D12 and the second voltage signal D14 in this embodiment are homologous, that is, they belong to the same source. As a result, except for the phase difference between the first voltage signal D12 and the second voltage signal D14, all other parameters are as similar as possible, thereby suppressing the impact of other parameters on the heating effect and display effect.

[0064] It should be noted that although this embodiment generates the second voltage signal D14 based on the first voltage signal D12 through the phase shift unit 312, or generates the fourth voltage signal D24 based on the third voltage signal D22, the aforementioned embodiments in which the first voltage signal D12 and the second voltage signal D14 are generated by two separate voltage driving units, the structural description of the first electrode layer 302 and the second electrode layer 304, the partitioning control of the liquid crystal layer 200, and the realization of 2D display and 3D display, etc., are also applicable to this embodiment and are not repeated here.

[0065] In one embodiment of the present application, Figure 11 As shown, Figure 11 This is a schematic diagram of the electrical connections of a first electrode layer in a display panel provided in the present application. The display panel also includes a fourth voltage driving unit 314 and a fifth voltage driving unit 316. The driving signal includes a third driving signal, and the third driving signal includes a fifth voltage signal D32 and a sixth voltage signal D34. The fourth voltage driving unit 314 is electrically connected to one end of the first electrode layer 302 to generate the fifth voltage signal D32. The fifth voltage driving unit 316 is electrically connected to the other end of the first electrode layer 302 to generate the sixth voltage signal D34. A preset voltage difference exists between the fifth voltage signal D32 and the sixth voltage signal D34. The value of the preset voltage difference is not zero.

[0066] One end of the first electrode layer 302 inputs the fifth voltage signal D32, and the other end of the first electrode layer 302 inputs the sixth voltage signal D34. The first electrode layer 302 and the second electrode layer 304 can also realize the first function based on the fifth voltage signal D32 and the sixth voltage signal D34. The first electrode layer 302 can also realize the second function based on the above-mentioned preset voltage difference.

[0067] As can be seen from the above, the display panel provided in this embodiment can also achieve heating of the liquid crystal layer 200 by directly creating a voltage difference between voltage signals applied to opposite ends of the first electrode layer 302. That is, different voltage signals are directly applied to opposite ends of the first electrode layer 302 to create a voltage difference between the opposite ends of the first electrode layer 302, thereby achieving heating of the liquid crystal layer 200. Since the magnitude of the voltage difference between the opposite ends of the first electrode layer 302 determines the magnitude of the current caused by the voltage difference, and thus determines the amount of heat that can be generated, that is, the degree of heating of the liquid crystal layer 200, heating of the liquid crystal layer 200 can be achieved by directly creating a voltage difference between voltage signals applied to opposite ends of the first electrode layer 302.

[0068] It should be noted that if heating of the liquid crystal layer 200 is achieved directly by applying a voltage difference between the voltage signals applied to opposite ends of the first electrode layer 302, the voltage difference between the two should not be too large, and the specific value of the preset voltage difference can be set according to actual conditions. It should also be noted that the aforementioned description of the structure of the first electrode layer 302 and the second electrode layer 304, as well as the partitioning control of the liquid crystal layer 200 and the implementation of 2D and 3D displays, described in the embodiment in which the first voltage signal D12 and the second voltage signal D14 are generated by two separate voltage driving units, also applies to this embodiment and will not be further elaborated here.

[0069] Correspondingly, the present application also provides a display device, which includes the display panel described in any of the above embodiments.

[0070] In addition, the present application also provides a processing method, which can be applied to the display panel described in any of the above embodiments. The display panel includes: a first substrate 102 and a second substrate 104 arranged opposite to each other, a liquid crystal layer 200 located between the first substrate 102 and the second substrate 104, a first electrode layer 302 located on the side of the first substrate 102 facing the second substrate 104, and a second electrode layer 304 located on the side of the second substrate 104 facing the first substrate 102. Figure 12 As shown, Figure 12 A flowchart of a processing method provided in this application, the processing method comprising:

[0071] S1: providing a driving signal to the first electrode layer 302 .

[0072] S2: A driving signal is input to the first electrode layer 302. The first electrode layer 302 and the second electrode layer 304 implement a first function based on the driving signal. The first electrode layer 302 also implements a second function based on the driving signal. The first function is to drive the liquid crystals in the liquid crystal layer 200 to deflect, and the second function is to heat the liquid crystal layer 200 to a preset temperature based on the ambient temperature of the display panel.

[0073] As can be seen from the above, this processing method can not only drive the deflection of the liquid crystal in the liquid crystal layer 200 by applying a drive signal to the first electrode layer 302 to achieve the display function, but also heat the liquid crystal layer 200 based on the ambient temperature of the display panel. In other words, this processing method can increase the temperature of the liquid crystal layer 200 when the ambient temperature of the display panel is low, or in other words, keep the liquid crystal layer 200 warm so that the temperature of the liquid crystal layer 200 is higher than the ambient temperature, thereby preventing problems such as liquid crystal precipitation and slow response speed caused by the low ambient temperature of the display panel. In other words, this processing method can heat up the liquid crystal layer 200, or keep the liquid crystal layer 200 warm, when the ambient temperature of the environment in which the display panel is located is low, thereby suppressing the influence of the ambient temperature of the environment in which the display panel is located on the temperature of the liquid crystal layer 200. That is, even if the ambient temperature of the environment in which the display panel is located is low, the liquid crystal layer 200 can be heated based on the driving signal through the first electrode layer 302, so that the liquid crystal layer 200 is at an appropriate temperature, and the temperature of the liquid crystal layer 200 is not affected by the ambient temperature, so as to suppress problems such as liquid crystal precipitation and slow response speed caused by the low ambient temperature of the environment in which the display panel is located.

[0074] Furthermore, this processing method can not only drive the deflection of the liquid crystals in the liquid crystal layer 200 to achieve the display function by applying a drive signal to the first electrode layer 302, but can also heat the liquid crystal layer 200 based on the ambient temperature of the display panel's environment. Furthermore, the first electrode layer 302 is a structure inherent in the display panel. In other words, this processing method can achieve heating of the liquid crystal layer 200 by utilizing the structure inherent in the display panel. This means that this processing method can be implemented without requiring major structural changes, requiring only modifications to the first electrode layer 302. There are no requirements for other components besides the first electrode layer 302, making it applicable to most liquid crystal display panels and highly practical.

[0075] In one embodiment of the present application, Figure 13 As shown, Figure 13 This is a flowchart of a processing method provided in the present application. Transmitting a driving signal to the first electrode layer 302 and the second electrode layer 304 includes:

[0076] S11: Provide a first driving signal to the first electrode layer 302. The first driving signal includes a first voltage signal D12 and a second voltage signal D14. The first voltage signal D12 and the second voltage signal D14 have the same voltage value, and there is a preset phase difference between the first voltage signal D12 and the second voltage signal D14. The value of the preset phase difference is not 0. It should be noted that the preset phase difference is the phase difference between the first voltage signal D12 and the second voltage signal D14 in the same pulse period of the first voltage signal D12 and the second voltage signal D14, that is, the preset phase difference is the phase difference between the i-th pulse period of the first voltage signal D12 and the i-th pulse period of the second voltage signal D14, where i≥1.

[0077] The frequency of the first voltage signal D12 and the frequency of the second voltage signal D14 may be the same, or the frequency of the first voltage signal D12 and the frequency of the second voltage signal D14 may be different. Figure 3 As shown, if the frequency of the first voltage signal D12 is the same as the frequency of the second voltage signal D14, then the preset phase difference between the first voltage signal D12 and the second voltage signal D14 can be generated by the phase shift between the pulse input time of the first voltage signal D12 and the pulse input time of the second voltage signal D14, that is, the preset phase difference can include the phase difference between the pulse input time of the first voltage signal D12 and the pulse input time of the second voltage signal D14 in the same pulse cycle. Figure 4 As shown, if the frequency of the first voltage signal D12 is different from the frequency of the second voltage signal D14, the preset phase difference between the first voltage signal D12 and the second voltage signal D14 can be caused by the phase shift between the pulse input moment of the first voltage signal D12 and the pulse input moment of the second voltage signal D14 in the same pulse cycle, and can also be caused by the difference between the frequency of the first voltage signal D12 and the frequency of the second voltage signal D12, that is, the above-mentioned preset phase difference can include the phase shift between the pulse input moment of the first voltage signal D12 and the pulse input moment of the second voltage signal D14, and the phase shift between the frequency of the first voltage signal D12 and the frequency of the second voltage signal D14. At least one of the phase differences caused by the different frequencies of the two voltage signals D12, that is, the above-mentioned preset phase difference may include the misaligned phase difference between the pulse input moment of the first voltage signal D12 and the pulse input moment of the second voltage signal D14, or the above-mentioned preset phase difference may include the phase difference caused by the different frequencies of the first voltage signal D12 and the second voltage signal D12, or the above-mentioned preset phase difference may include the misaligned phase difference between the pulse input moment of the first voltage signal D12 and the pulse input moment of the second voltage signal D14, and the phase difference caused by the different frequencies of the first voltage signal D12 and the second voltage signal D12.

[0078] The first electrode layer 302 and the second electrode layer 304 implement a first function based on the driving signal. The first electrode layer 302 also implements a second function based on the driving signal, including:

[0079] The first electrode layer 302 and the second electrode layer 304 implement a first function based on the first driving signal, and the first electrode layer 302 also implements a second function based on the first driving signal.

[0080] Specifically, the first electrode layer 302 and the second electrode layer 304 implement the first function based on the first driving signal, and the first electrode layer 302 also implements the second function based on the first driving signal, including:

[0081] S21: A first voltage signal D12 is input to one end of the first electrode layer 302, and a second voltage signal D14 is input to the other end of the first electrode layer 302. The first electrode layer 302 and the second electrode layer 304 implement a first function based on a portion of the first driving signal excluding a preset phase difference, and the first electrode layer 302 implements a second function based on the preset phase difference.

[0082] Based on the above, the first driving signal includes a first voltage signal D12 and a second voltage signal D14, and there is a preset phase difference greater than 0 between the first voltage signal D12 and the second voltage signal D14, that is, there is a phase difference between the first voltage signal D12 and the second voltage signal D14. Furthermore, since the first voltage signal D12 is input to one end of the first electrode layer 302 and the second voltage signal D14 is input to the first electrode layer 302, that is, the first voltage signal D12 and the second voltage signal D14 with a phase difference are respectively input to the two ends of the first electrode layer 302, a voltage difference is generated between the two opposite ends of the first electrode layer 302 due to the phase difference between the first voltage signal D12 and the second voltage signal D14, thereby generating a current between the two ends of the first electrode layer 302. Since heat is generated when current flows through a conductor with resistance, the current generated between the two ends of the first electrode layer 302 causes the first electrode layer 302 to generate heat due to the generated current, thereby heating the liquid crystal layer 200. The first electrode layer 302 and the second electrode layer 304 can realize the first function based on the part of the first driving signal except the preset phase difference, that is, realize liquid crystal display based on the voltage signal provided by the first electrode layer 302 and the second electrode layer 304 to the liquid crystal layer 200. This is well known to those skilled in the art and will not be repeated here.

[0083] It should be noted that a voltage difference is generated at both ends of the first electrode layer 302 due to the phase difference between the first voltage signal D12 and the second voltage signal D14. Specifically, although the voltage values of the first voltage signal D12 and the second voltage signal D14 are the same, according to Figure 3 and Figure 4It can be seen that when there is a phase difference between the first voltage signal D12 and the second voltage signal D14, during the time period corresponding to the phase difference, that is, during the phase difference maintenance period, the voltages of the first voltage signal D12 and the second voltage signal D14 are not equal, and thus a voltage difference will be generated at both ends of the first electrode layer 302 due to the phase difference between the first voltage signal D12 and the second voltage signal D14.

[0084] In one embodiment of the present application, Figure 14 As shown, Figure 14 This is a flow chart of a processing method provided by the present application. The first electrode layer 302 implements the second function based on a preset phase difference, including:

[0085] S22: Obtaining a preset phase difference based on the ambient temperature of the display panel.

[0086] S23: The first electrode layer 302 realizes the second function based on the preset phase difference.

[0087] It is known that the phase difference between the first voltage signal D12 and the second voltage signal D14 can affect the degree to which the first electrode layer 302 and the second electrode layer 304 heat the liquid crystal layer 200. Specifically, the greater the phase difference between the first voltage signal D12 and the second voltage signal D14, the longer the first electrode layer 302 heats the liquid crystal layer 200 based on the phase difference between the first voltage signal D12 and the second voltage signal D14, and the greater the degree of heating of the liquid crystal layer 200. Conversely, the smaller the phase difference between the first voltage signal D12 and the second voltage signal D14, the shorter the first electrode layer 302 heats the liquid crystal layer 200 based on the phase difference between the first voltage signal D12 and the second voltage signal D14, and the less heating of the liquid crystal layer 200. Based on this, in the above steps, when the first electrode layer 302 implements the second function based on the first drive signal, it can obtain a preset phase difference based on the ambient temperature of the display panel, that is, obtain a phase difference between the first voltage signal D12 and the second voltage signal D14, thereby heating the liquid crystal layer 200 based on the ambient temperature of the display panel. Specifically, for example, when the ambient temperature of the display panel is low, the preset phase difference obtained is large. Conversely, when the ambient temperature of the display panel is high, the preset phase difference obtained is small, thereby heating the liquid crystal layer 200 based on the ambient temperature of the display panel.

[0088] In one embodiment of the present application, Figure 15 As shown, Figure 15 This is a flow chart of a processing method provided in the present application, wherein providing a driving signal to the first electrode layer 302 further includes:

[0089] S12: providing a second driving signal to the first electrode layer 302. The third voltage signal D22 and the fourth voltage signal D24 have the same voltage value and the same phase.

[0090] The first electrode layer 302 and the second electrode layer 300 implement the first function based on the driving signal and further include:

[0091] The first electrode layer 302 and the second electrode layer 304 implement the first function based on the second driving signal.

[0092] The first electrode layer 302 and the second electrode layer 304 implement the first function based on the second driving signal, including:

[0093] S24: A third voltage signal D22 is input to one end of the first electrode layer 302, and a fourth voltage signal D24 is input to the other end of the first electrode layer 302, so that the first electrode layer 302 and the second electrode layer 304 can achieve the first function based on the second drive signal. The second drive signal is not transmitted to the first electrode layer 302 and the second electrode layer 304 simultaneously with the first drive signal.

[0094] When the ambient temperature of the display panel does not cause problems such as liquid crystal precipitation in the liquid crystal layer 200 and slow response speed, that is, when the ambient temperature of the display panel is suitable, the liquid crystal layer 200 does not need to be heated, or the liquid crystal layer 200 in the display panel is already at a suitable temperature and does not need to be further heated, thereby eliminating the need for a phase difference between the voltage signals input to the opposite ends of the first electrode layer 302. Therefore, the processing method further includes providing a second drive signal to the first electrode layer 302, and the third voltage signal D22 and the fourth voltage signal D24 in the second drive signal have the same voltage value and the same phase. Therefore, when heating of the liquid crystal layer 200 is not required, the third voltage signal D22 and the fourth voltage signal D24 can be transmitted to the opposite ends of the first electrode layer 302 respectively, thereby achieving liquid crystal display, that is, achieving the first function.

[0095] In one embodiment of the present application, Figure 16 As shown, Figure 16 This is a flow chart of a processing method provided in the present application. Providing a driving signal to the first electrode layer 302 includes:

[0096] S13: providing a third driving signal to the first electrode layer 302, the third driving signal including a fifth voltage signal D32 and a sixth voltage signal D34. There is a preset voltage difference between the fifth voltage signal D32 and the sixth voltage signal D34, and the value of the preset voltage difference is not zero.

[0097] The first electrode layer 302 and the second electrode layer 304 implement a first function based on the driving signal, and the first electrode layer 302 implements a second function based on the driving signal including:

[0098] The first electrode layer 302 and the second electrode layer 304 implement the first function based on the third driving signal, and the first electrode layer 302 implements the second function based on the third driving signal. The first electrode layer 302 and the second electrode layer 304 implement the first function based on the third driving signal, and the first electrode layer 302 implements the second function based on the third driving signal include:

[0099] S25: The fifth voltage signal D32 is input to one end of the first electrode layer 302, and the sixth voltage signal D34 is input to the other end of the first electrode layer 302. The first electrode layer 302 and the second electrode layer 304 can implement the first function based on the fifth voltage signal D32 and the sixth voltage signal D34. The first electrode layer 302 can implement the second function based on the preset voltage difference.

[0100] As can be seen from the above, this processing method can also achieve heating of the liquid crystal layer 200 by directly creating a voltage difference between the voltage signals applied to the opposite ends of the first electrode layer 302. That is, different voltage signals are directly applied to the opposite ends of the first electrode layer 302 to create a voltage difference between the opposite ends of the first electrode layer 302, thereby achieving heating of the liquid crystal layer 200. Since the magnitude of the voltage difference between the opposite ends of the first electrode layer 302 determines the magnitude of the current caused by the voltage difference, and thus determines the amount of heat that can be generated, that is, the degree of heating of the liquid crystal layer 200, heating of the liquid crystal layer 200 can be achieved by directly creating a voltage difference between the voltage signals applied to the opposite ends of the first electrode layer 302.

[0101] In one embodiment of the present application, Figure 17 As shown, Figure 17 This is a flow chart of a processing method provided by the present application. The first electrode layer 302 implements the second function based on a preset voltage difference, including:

[0102] S26: Obtaining a preset voltage difference based on the ambient temperature of the display panel.

[0103] S27: The first electrode layer 302 realizes the second function based on the preset voltage difference.

[0104] It is known that the voltage difference between the opposite ends of the first electrode layer 302 determines the magnitude of the current caused by the voltage difference, and thus the amount of heat that can be generated. Therefore, when the first electrode layer 302 performs the second function based on the third drive signal, it can obtain a preset voltage difference based on the ambient temperature of the display panel. For example, when the ambient temperature of the display panel is low, the preset voltage difference obtained is large. Conversely, when the ambient temperature of the display panel is high, the preset voltage difference obtained is small, thereby achieving heating of the liquid crystal layer 200 based on the ambient temperature of the display panel.
