Description

Technical Field

[0001] This invention relates to the field of display technology, and more particularly to a display device. Background Technology

[0002] With the development of display technology, the application scenarios of 3D displays are becoming increasingly diverse. Therefore, research on display devices that can achieve both 2D and 3D displays has become a research hotspot in this field. Currently, the method for display devices to achieve 2D and 3D displays is to superimpose a liquid crystal prism panel on the display side of the display panel. By controlling the liquid crystal molecules in the liquid crystal prism panel to different states, the display device can switch between 2D and 3D displays.

[0003] The liquid crystal prism panel includes multiple strip electrodes. When the display device performs 3D display, different voltages are applied to the multiple electrodes, causing the liquid crystal molecules at each electrode location to be in different states, resulting in different delays at each electrode location and creating a prism effect. This allows the left and right eyes to see different images, forming a 3D sensation through parallax. Summary of the Invention

[0004] The present invention provides a display device that reduces the complexity of the driving circuit of the liquid crystal prism panel and lowers the hardware requirements for the driving circuit of the liquid crystal prism panel.

[0005] The present invention provides a display device, including a liquid crystal prism panel, the liquid crystal prism panel including a plurality of electrode groups, the electrode groups including a plurality of electrodes arranged in sequence at intervals; The absolute voltage values ​​on at least two of the electrodes in the electrode group include a first voltage segment, and within the duration of a first time period, the proportion of the duration of the absolute voltage values ​​on the at least two electrodes being in the first voltage segment within the duration of the first time period is different.

[0006] In this embodiment of the invention, pulse width signals are used to drive the electrodes. This allows at least two electrodes to be driven with voltages whose absolute values ​​fall within the first voltage segment, reducing the complexity of the driving circuit for the liquid crystal prism panel and lowering the hardware requirements for the driving circuit. By adjusting the proportion of time during which the absolute value of the voltage on the electrode falls within the first voltage segment within a first time period, different average voltages on the electrodes are obtained. This allows different electrodes to have different average voltages within the same first voltage segment, thus meeting the requirement of different electrodes for different average voltages.

Detailed Implementation

[0009] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0010] Figure 1 This is a cross-sectional structural diagram of a liquid crystal prism panel provided in an embodiment of the present invention; see reference. Figure 1 The liquid crystal prism panel 20 includes a first substrate 201, an opposing substrate 202, and a liquid crystal layer 203. The liquid crystal layer 203 is located between the first substrate 201 and the opposing substrate 202. The liquid crystal layer 203 includes liquid crystal molecules. The liquid crystal prism panel 20 includes a plurality of prism units 210 ( Figure 1 (A prism unit is schematically shown in the diagram). Multiple prism units 210 are arranged along a first direction X. Each prism unit 210 includes multiple electrodes 211 and opposing electrodes 212. The multiple electrodes 211 in one prism unit 210 form an electrode group 21. The multiple electrodes 211 are located between the first substrate 201 and the liquid crystal layer 203, wherein... Figure 1 The 16 electrodes 211 shown in the diagram of a prism unit 210 are merely schematic; the number of electrodes 211 can be designed according to actual conditions in specific implementations. Multiple electrodes 211 are spaced apart from each other along a first direction X. Along the first direction X, adjacent electrodes 211 are spaced a certain distance apart. Multiple prism units 210 share the same opposing electrode 212; for example, the opposing electrode 212 is a full-surface electrode. During 3D display, a voltage difference exists between the electrodes 211 and the opposing electrode 212. The longitudinal electric field formed by the electrodes 211 and the opposing electrode 212 can drive the liquid crystal molecules to rotate, thereby modulating the beam transmission direction of the prism unit 210. However, each electrode group 21 requires different voltages to be applied to its multiple electrodes 211 to achieve the ideal delay distribution, making the voltage signal generation hardware complex. For example, 16 different voltages need to be applied to the 16 electrodes 211 to achieve the ideal delay distribution.

[0011] Figure 2 A driving timing diagram of a liquid crystal prism panel provided in an embodiment of the present invention; see reference. Figure 1 and Figure 2 The display device includes a liquid crystal prism panel, which includes multiple electrode groups 21. Due to space limitations, in... Figure 1An electrode group 21 is illustrated. Multiple electrode groups 21 are arranged along a first direction X. Each electrode group 21 includes multiple electrodes 211 arranged at intervals in sequence. The absolute voltage value on at least two electrodes 211 in the electrode group 21 includes a first voltage segment, which includes a positive voltage or a range including a positive voltage. The absolute voltage values ​​on at least two electrodes 211 within the first voltage segment may have the same value or different values. Within a first time period T, the proportion of time during which the absolute voltage values ​​on the at least two electrodes 211 are within the first voltage segment differs. Here, the first time period T represents the length of time, and is not a fixed time period with a fixed start and end point.

[0012] For example, at least two electrodes 211 include a first electrode E1 and a second electrode E2. Taking the first electrode E1 and the second electrode E2 as examples, the proportion of time during which the absolute value of the voltage on the first electrode E1 is in the first voltage segment within the duration of the first time period T is different from the proportion of time during which the absolute value of the voltage on the second electrode E2 is in the first voltage segment within the duration of the first time period T.

[0013] The longitudinal electric field formed by electrode 211 and the opposing electrode 212 controls the rotation of liquid crystal molecules. Within the same electrode group 21, by applying voltage to each electrode 211 and applying different voltages to adjacent electrodes 21, the rotation degree of the liquid crystal molecules is different, causing the corresponding positions of the electrode group 21 to form liquid crystal lenses or liquid crystal prisms, enabling the display device to enter 3D mode. The meanings of the first time period T and the first voltage segment mentioned in this application can be further explained through the above description of the basic technology. For example, the voltage at which liquid crystal molecules form liquid crystal lenses or liquid crystal prisms can be temporarily referred to as the prism voltage. In order to form liquid crystal lenses or liquid crystal prisms, the voltages on electrodes 211 within the same electrode group 21 are different. Therefore, the voltage for controlling the formation of liquid crystal lenses or liquid crystal prisms can be a voltage range, i.e., the first voltage segment. The first time period T is the period during which voltage is applied to electrode 211. For the same electrode 21, voltage is repeatedly applied to electrode 21 with the first time period T as the period. In one embodiment, such as Figure 2 As shown, the voltage application periods for each electrode 211 coincide. For multiple electrodes 21, voltage is repeatedly applied to these electrodes 21 with a first time period T as the period. The position of the voltage switching time between any two of these electrodes 21 is fixed in the first time period T and does not change with the change of the first time period T. That is to say, the relative phase of the turn-on time of any two of these electrodes 21 remains constant.

[0014] In this embodiment of the invention, pulse width signals are used to drive the electrodes 211. This allows at least two electrodes 211 to be driven by voltages whose absolute values ​​fall within the first voltage segment, reducing the complexity of the driving circuit for the liquid crystal prism panel and lowering the hardware requirements for the driving circuit. By adjusting the proportion of time during which the absolute value of the voltage on the electrode 211 falls within the first voltage segment within a first time period T, different average voltages on the electrode 211 are obtained. This allows different electrodes 211 to have different average voltages within the same first voltage segment, satisfying the requirement for different average voltages for different electrodes 211. The average voltage is the effective voltage.

[0015] Optionally, refer to Figure 1 and Figure 2 The first voltage segment is a first voltage, which is a fixed value. Thus, at least two electrodes 211 are driven with a voltage whose absolute value is the first voltage. Under the same first voltage, different electrodes 211 have different average voltages, satisfying the requirement of different average voltages for different electrodes 211. This further reduces the complexity of the driving circuit of the liquid crystal prism panel and lowers the hardware requirements for the driving circuit.

[0016] Optionally, refer to Figure 1 and Figure 2 For electrodes 211 with different percentages of absolute voltage values ​​in the first voltage segment within the first time period T, the absolute voltage values ​​on at least two electrodes 211 are in the first voltage segment for different durations within the first time period T.

[0017] For example, the duration for which the absolute value of the voltage on the first electrode E1 is in the first voltage segment is t1, and the duration for which the absolute value of the voltage on the second electrode E2 is in the first voltage segment is t2, where t1 and t2 are different. The proportion of t1 within the first time period T is... The proportion of t2 within the first time period T is , and different.

[0018] Optionally, refer to Figure 1 and Figure 2 Electrode 211 includes an i-th electrode, where i is a positive integer. During a first time period T, the absolute value of the voltage on the i-th electrode includes a first voltage segment and a second voltage, where the absolute values ​​of the voltages in the first voltage segment and the second voltage are different. In this embodiment of the invention, the driving signal for the i-th electrode includes at least two parts with different absolute voltage values, thereby driving the i-th electrode at different time periods by alternating voltage. Furthermore, by adjusting the proportion of time the i-th electrode is in the first voltage segment, the average voltage of the i-th electrode is adjusted to a preset average voltage value for the i-th electrode.

[0019] For example, the second voltage is a fixed value. The absolute value of the second voltage can be less than the voltage in the first voltage segment. Thus, the second voltage serves as a reference voltage, and the voltage in the first voltage segment serves as a driving voltage. When the voltage applied to electrode 211 is the driving voltage, the liquid crystal molecules are driven to rotate to a corresponding angle according to the value of the driving voltage. When the voltage applied to electrode 211 is the reference voltage, the liquid crystal molecules rotate to a preset initial position according to the reference voltage, or do not rotate but maintain the state and angle before the reference voltage was applied. For example, the second voltage can be 0V. In one embodiment, by changing the duration of the driving voltage, the ratio of the duration of the driving voltage to the reference voltage is changed, thus changing the value of the average voltage of the driving voltage and the reference voltage, thereby changing the ability to drive the liquid crystal molecules to rotate. It should be noted that the average voltage here is not the arithmetic mean of the driving voltage and the reference voltage, but rather a time-weighted average of the two.

[0020] For example, when the i-th electrode is the first electrode E1, the absolute value of the voltage on the first electrode E1 includes a first voltage segment and a second voltage. Taking the electrode group 21, which includes 16 electrodes 211, as an example, the 16 electrodes 211 are sequentially the first electrode E1, the second electrode E2, the third electrode E3, the fourth electrode E4, the fifth electrode E5, the sixth electrode E6, the seventh electrode E7, the eighth electrode E8, the ninth electrode E9, the tenth electrode E10, the eleventh electrode E11, the twelfth electrode E12, the thirteenth electrode E13, the fourteenth electrode E14, the fifteenth electrode E15, and the sixteenth electrode E16. The absolute voltage values ​​on all electrodes 211 in electrode group 21 include a first voltage segment and a second voltage. That is, the absolute voltage values ​​on the first electrode E1, second electrode E2, third electrode E3, fourth electrode E4, fifth electrode E5, sixth electrode E6, seventh electrode E7, eighth electrode E8, ninth electrode E9, tenth electrode E10, eleventh electrode E11, twelfth electrode E12, thirteenth electrode E13, fourteenth electrode E14, fifteenth electrode E15, and sixteenth electrode E16 include both a first voltage segment and a second voltage. In one embodiment, the driving circuit of the liquid crystal prism panel only needs to achieve voltages with absolute values ​​within the first voltage segment and the second voltage, reducing the requirement for the number of driving voltages. This reduces the complexity of the driving circuit of the liquid crystal prism panel and lowers the hardware requirements for the driving circuit.

[0021] Figure 3 This is a driving timing diagram for another liquid crystal prism panel provided in an embodiment of the present invention; see reference. Figure 1 and Figure 3Electrode 211 also includes a j-th electrode. The i-th electrode and the j-th electrode are located in the same electrode group 21, where j is a positive integer. During the duration of the first time period T, the absolute voltage value on the j-th electrode includes a first voltage segment and a second voltage. The proportion of time during which the absolute voltage value on the i-th electrode is in the first voltage segment within the duration of the first time period T is different from the proportion of time during which the absolute voltage value on the j-th electrode is in the first voltage segment within the duration of the first time period T. In this embodiment of the invention, the driving signal of the i-th electrode includes at least two parts with different absolute voltage values, and the driving signal of the j-th electrode also includes at least two parts with different absolute voltage values. Thus, the i-th electrode is driven by alternating voltage at different time periods, and the j-th electrode is driven by alternating voltage at different time periods. The absolute voltage values ​​on the i-th electrode and the j-th electrode include a first voltage segment and a second voltage. The driving signals on the i-th electrode and the j-th electrode have portions with the same absolute voltage value, and these portions have different duration proportions.

[0022] For example, when the i-th electrode is the first electrode E1, the absolute value of the voltage on the first electrode E1 includes a first voltage segment and a second voltage. When the j-th electrode is the eighth electrode E8, the absolute value of the voltage on the eighth electrode E8 includes a first voltage segment and a second voltage. The duration for which the absolute value of the voltage on the eighth electrode E8 is in the first voltage segment is t8, and t1 is different from t8. The proportion of t1 within the duration of the first time period T is... The proportion of t8 within the first time period T is , and different.

[0023] For example, the proportion of time during which the absolute value of the voltage on the i-th electrode is at the second voltage within the first time period T is different from the proportion of time during which the absolute value of the voltage on the j-th electrode is at the second voltage within the first time period T. Within the first time period T, the duration of time during which the absolute value of the voltage on the i-th electrode is at the second voltage is different from the duration of time during which the absolute value of the voltage on the j-th electrode is at the second voltage.

[0024] Optionally, refer to Figure 1 and Figure 3Electrode 211 includes the k-th electrode. The i-th, j-th, and k-th electrodes are located in the same electrode group 21, and the i-th, j-th, and k-th electrodes are arranged sequentially along the arrangement direction of electrode 211; the i-th, j-th, and k-th electrodes are arranged sequentially along the first direction X. The percentage of time during which the absolute value of the voltage on the i-th electrode is in the first voltage segment within the first time period T is greater than the percentage of time during which the absolute value of the voltage on the j-th electrode is in the first voltage segment within the first time period T; the percentage of time during which the absolute value of the voltage on the k-th electrode is in the first voltage segment within the first time period T is greater than the percentage of time during which the absolute value of the voltage on the j-th electrode is in the first voltage segment within the first time period T. i < j < k, where k is a positive integer. The i-th and k-th electrodes are located near the edge of the electrode group 21, and the j-th electrode is located near the middle of the electrode group 21. For multiple electrodes 211 in the same electrode group 21, the proportion of time that the electrode 211 located near the edge of the electrode group 21 is in the first voltage segment within the first time period T is greater than the proportion of time that the electrode 211 located near the middle of the electrode group 21 is in the first voltage segment within the first time period T.

[0025] For example, the i-th electrode is the first electrode E1, the j-th electrode is the eighth electrode E8, and the k-th electrode is the sixteenth electrode E16. The duration for which the absolute value of the voltage on the sixteenth electrode E16 is in the first voltage segment is t16, where t1 is greater than t8 and t16 is greater than t8. The proportion of T16 within the first time period T is... , Greater than , It should be noted that the i-th electrode can be any other electrode 211 besides the first electrode E1, the j-th electrode can be any other electrode 211 besides the eighth electrode E8, and the k-th electrode can be any other electrode 211 besides the sixteenth electrode E16.

[0026] Optionally, refer to Figure 1 and Figure 3Within the same electrode group 21, along the arrangement direction of the electrodes 211, the proportion of time during which the absolute voltage value on multiple electrodes 211 is in the first voltage segment within the first time period T gradually decreases and then gradually increases. For multiple electrodes 211 in the same electrode group 21, the closer an electrode 211 is to the edge of the electrode group 21, the greater the proportion of time it is in the first voltage segment within the first time period T; the closer an electrode 211 is to the center of the electrode group 21, the smaller the proportion of time it is in the first voltage segment within the first time period T. The electrodes 211 on both sides of the electrode group 21 have a high proportion of time during the first voltage segment within the first time period T, and as they move towards the center of the electrode group 21, the proportion of time during the first voltage segment decreases from one end of the electrode group 21 to the other.

[0027] Figure 4 This is a schematic diagram of the average voltage of each electrode in a liquid crystal prism panel provided in an embodiment of the present invention; see reference. Figure 4 For multiple electrodes 211 in the same electrode group 21, the average voltage of the electrodes 211 closer to the edge of the electrode group 21 is greater, and the average voltage of the electrodes 211 closer to the middle of the electrode group 21 is smaller. Thus, along the first direction X, the multiple electrodes 211 and the opposing electrode 212 form a gradually changing voltage difference, and the multiple electrodes 211 and the opposing electrode 212 form a gradually changing longitudinal electric field, achieving an ideal delay distribution, so that the prism unit 210 has optical characteristics similar to a prismatic prism. (Refer to reference...) Figure 3 and Figure 4 The electrodes 211 on both sides of the electrode group 21 are in the first voltage segment for a high proportion within the first time period T, and are oriented towards the center of the electrode group 21. The proportion of time that the electrodes 211 are in the first voltage segment decreases within the first time period T, thus forming a... Figure 4 The average voltage distribution of each electrode shown is as follows: the average voltage of the electrodes 211 on both sides of the electrode group 21 is high, and the average voltage of the electrodes 211 decreases towards the center of the electrode group 21. The proportion of time that the electrodes 211 at the edge of the electrode group 21 are in the first voltage segment within the first time period T is greater than the proportion of time that the electrodes 211 at the middle position of the electrode group 21 are in the first voltage segment within the first time period T.

[0028] For example, at least two of the first electrodes E1 to the sixteenth electrode E16 have the same average voltage. For instance, the second electrode E2 and the sixteenth electrode E16 have the same average voltage. Alternatively, any two of the first electrodes E1 to the sixteenth electrode E16 may have different average voltages. Because the alignment of liquid crystal molecules has a pretilt angle, and the friction direction of the alignment film is from right to left or from left to right, the pretilt angle and the friction direction cause asymmetry. In actual products, the voltages of the first electrodes E1 to the sixteenth electrode E16 are asymmetrical to ensure that the retardation is symmetrical. It is not that the second electrode E2 and the sixteenth electrode E16 have the same average voltage, the third electrode E3 and the fifteenth electrode E15 have the same average voltage, ..., the eighth electrode E8 and the tenth electrode E10 have the same average voltage.

[0029] Optionally, electrode 211 includes the i-th electrode, where i is a positive integer, and the average voltage of the i-th electrode is... satisfy: in, The duration during which the absolute value of the voltage on the i-th electrode remains at the first voltage. The duration of the first time period. This is the first voltage. The first voltage can be a positive voltage or a negative voltage; correspondingly, it represents the average voltage of the i-th electrode. It can be a positive or negative voltage. As can be seen from the above formula, The larger the value of , the longer the absolute value of the voltage on the i-th electrode remains at the first voltage, the larger the proportion of the time during which the absolute value of the voltage on the i-th electrode remains at the first voltage within the first time period T, and the larger the average voltage of the i-th electrode. The larger the absolute value, the greater. The smaller the value, the shorter the duration for which the absolute value of the voltage on the i-th electrode is at the first voltage, and the smaller the proportion of the duration for which the absolute value of the voltage on the i-th electrode is at the first voltage within the first time period T. The average voltage of the i-th electrode... The smaller the absolute value, the better. For example, as i changes from 1 to 16, the i-th electrode can be one of the first electrode E1 to the sixteenth electrode E16.

[0030] Figure 5 This is a driving timing diagram for another liquid crystal prism panel provided in an embodiment of the present invention; see reference. Figure 1 and Figure 5In the same electrode group 21, at least two electrodes 211 have different activation times in the first voltage segment, and the time periods when the absolute voltage values ​​of the at least two electrodes 211 are in the first voltage segment overlap. It is understood that at the voltage switching moment, i.e., at the rising or falling edge of the driving signal voltage, the disturbance is relatively large, and it is easy for the driving current to be momentarily excessive. In this embodiment of the invention, the activation times of at least two electrodes 211 in the first voltage segment are staggered, and the driving current provided by the driving circuit of the liquid crystal prism panel to the at least two electrodes 211 at different times reduces the value of the driving current provided by the driving circuit and avoids the occurrence of momentarily excessive driving current.

[0031] For example, the driving signal applied to the same electrode 211 is an AC signal. In a first time period T, the driving signal includes a positive voltage; in another first time period T, the driving signal includes a negative voltage. At least two electrodes 211 are at different times when the positive voltage is applied, and / or at least two electrodes 211 are at different times when the negative voltage is applied. For example, Figure 5 In the second first time period T, the driving signal on the first electrode E1 includes a negative voltage, and the driving signal on the second electrode E2 includes a negative voltage. The turn-on time of the negative voltage on the first electrode E1 is different from the turn-on time of the negative voltage on the second electrode E2. Figure 5 In the third first time period T, the driving signal on the first electrode E1 includes a positive voltage, and the driving signal on the second electrode E2 also includes a positive voltage. The on-time of the positive voltage on the first electrode E1 is different from the on-time of the positive voltage on the second electrode E2. At least two electrodes 211 include a first electrode E1 and a second electrode E2. Taking the first electrode E1 and the second electrode E2 as examples, the on-time when the absolute value of the voltage on the first electrode E1 is in a first voltage segment is the first on-time, and the on-time when the absolute value of the voltage on the second electrode E2 is in the first voltage segment is the second on-time. The first on-time and the second on-time are different. There is a first time interval of s1 between the first on-time and the second on-time.

[0032] For example, the driving timing of the liquid crystal prism panel does not need to distinguish between the first and second frames; there is no concept of a global frame, and it does not need to be aligned with an external driving signal. The voltage on each electrode 211 changes periodically, with each electrode changing according to its own cycle. The timing of the voltage switching of different electrodes 211 being earlier or later has the same effect on the prism beam splitting effect achieved by the liquid crystal prism panel. Staggering the voltage switching times of different electrodes 211 results in different phases for the driving signals corresponding to different electrodes 211. For example... Figure 5 The waveform of the second electrode E2 shown is equivalent to that at... Figure 2 Based on the waveform of the second electrode E2 shown, the entire waveform is shifted to the left by a first time interval of s1. In other words, Figure 5 The start time of the first time interval T of the second electrode E2 shown is equivalent to the time when... Figure 5 Based on the start time of the first time period T of the first electrode E1 shown, the time interval of s1 is shifted to the left. Frames whose turn-on times are compared overlap in the turn-on time period or in the time period where the absolute voltage value is within the first voltage segment. For example, Figure 5 In the process, the time period when the absolute value of the voltage of the first electrode E1 is in the first voltage segment overlaps with the time period when the absolute value of the voltage of the second electrode E2 is in the first voltage segment.

[0033] Figure 6 This is a driving timing diagram for another liquid crystal prism panel provided in an embodiment of the present invention; see reference. Figure 1 and Figure 6 Electrodes 211 in the same electrode group 21 include the i-th electrode, the j-th electrode, and the k-th electrode, which are arranged sequentially along the arrangement direction of the electrodes 211, where i < j < k, and i, j, and k are positive integers. The absolute voltage value on the i-th electrode is at the start time of the first voltage segment after the absolute voltage value on the j-th electrode is at the start time of the first voltage segment, and the absolute voltage value on the k-th electrode is at the start time of the first voltage segment after the absolute voltage value on the j-th electrode is at the start time of the first voltage segment. The time periods when the absolute voltage values ​​on the i-th, j-th, and k-th electrodes are in the first voltage segment overlap. The i-th and k-th electrodes are located near the edge of the electrode group 21, and the j-th electrode is located near the middle of the electrode group 21. For multiple electrodes 211 in the same electrode group 21, the electrode 211 near the edge of the electrode group 21 is at the start time of the first voltage segment, and the electrode 211 located near the middle of the electrode group 21 is at the start time of the first voltage segment later than the electrode 211 located near the middle of the electrode group 21.

[0034] For example, the i-th electrode is the first electrode E1, the j-th electrode is the eighth electrode E8, and the k-th electrode is the sixteenth electrode E16. The absolute value of the voltage on the eighth electrode E8 at the start time of the first voltage segment of the first electrode E1 is after the start time of the first voltage segment. The absolute value of the voltage on the sixteenth electrode E16 at the start time of the first voltage segment is after the absolute value of the voltage on the eighth electrode E8 at the start time of the first voltage segment.

[0035] Optionally, refer to Figure 1 and Figure 6Within the same electrode group 21, along the arrangement direction of the electrodes 211, the absolute voltage values ​​on multiple electrodes 211 at the start time of the first voltage segment gradually advance and then gradually delay. For multiple electrodes 211 in the same electrode group 21, the closer an electrode 211 is to the edge of the electrode group 21, the later its start time in the first voltage segment; the closer an electrode 211 is to the center of the electrode group 21, the earlier its start time in the first voltage segment. The electrodes 211 on both sides of the electrode group 21 start at a later time in the first voltage segment, and as they move towards the center of the electrode group 21, their start time in the first voltage segment gradually advances. The start time of the first voltage segment for the electrodes 211 at the edge of the electrode group 21 is later than that of the electrodes 211 at the center of the electrode group 21.

[0036] Figure 7 This is a driving timing diagram for another liquid crystal prism panel provided in an embodiment of the present invention; see reference. Figure 1 and Figure 7 Electrodes 211 in the same electrode group 21 include the i-th electrode, the j-th electrode, and the k-th electrode, which are arranged sequentially along the arrangement direction of the electrodes 211, i < j < k, where i, j, and k are positive integers. The absolute voltage value on the i-th electrode is in the first voltage segment at a time earlier than the absolute voltage value on the j-th electrode, and the absolute voltage value on the k-th electrode is in the first voltage segment at a time earlier than the absolute voltage value on the j-th electrode. The time periods when the absolute voltage values ​​on the i-th, j-th, and k-th electrodes are in the first voltage segment overlap. The i-th and k-th electrodes are located near the edge of the electrode group 21, and the j-th electrode is located near the middle of the electrode group 21. For multiple electrodes 211 in the same electrode group 21, the electrode 211 near the edge of the electrode group 21 is in the first voltage segment at a time earlier than the electrode 211 near the middle of the electrode group 21.

[0037] For example, the i-th electrode is the first electrode E1, the j-th electrode is the eighth electrode E8, and the k-th electrode is the sixteenth electrode E16. The absolute value of the voltage on the eighth electrode E8 at the start time of the first voltage segment of the first electrode E1 is earlier than the start time of the first voltage segment of the eighth electrode E8.

[0038] Optionally, refer to Figure 1 and Figure 7Within the same electrode group 21, along the arrangement direction of the electrodes 211, the absolute voltage values ​​on multiple electrodes 211 at the start time of the first voltage segment gradually increase, first gradually decreasing and then gradually increasing. For multiple electrodes 211 within the same electrode group 21, the closer an electrode 211 is to the edge of the electrode group 21, the earlier it starts to operate in the first voltage segment; the closer an electrode 211 is to the center of the electrode group 21, the later it starts to operate in the first voltage segment. The electrodes 211 on both sides of the electrode group 21 start to operate in the first voltage segment earlier, and as they move towards the center of the electrode group 21, their start time in the first voltage segment gradually decreases. The electrodes 211 at the edge of the electrode group 21 start to operate in the first voltage segment earlier than the electrodes 211 at the center of the electrode group 21.

[0039] Optionally, refer to Figure 3 In the same electrode group 21, the absolute voltage values ​​on at least two electrodes 211 are at the same start time of the first voltage segment, and the time periods during which the absolute voltage values ​​on the at least two electrodes 211 are in the first voltage segment overlap. The at least two electrodes 211 are located within the same first time period T.

[0040] In other embodiments, the absolute values ​​of the voltages on at least two electrodes 211 in the same electrode group 21 are at the same end time of the first voltage segment, and the end time of the first voltage segment is the start time of the second voltage. The absolute values ​​of the voltages on at least two electrodes 211 in the same electrode group 21 are at the same start time of the second voltage. In one embodiment, the second voltage is a common voltage, for example, 0V. Even if the at least two electrodes 211 are at the same start time of the second voltage, there is no need for the driving circuit of the liquid crystal prism panel to provide driving current, or no need for the driving circuit of the liquid crystal prism panel to provide a large driving current.

[0041] Optionally, refer to Figure 3 , Figure 6 or Figure 7 In the same electrode group 21, the absolute voltage values ​​on at least two electrodes 211 end at different times in the first voltage segment, and the time periods when the absolute voltage values ​​on these at least two electrodes 211 are in the first voltage segment overlap. The end time of the first voltage segment is the start time of other voltages; for example, the end time of the first voltage segment is the start time of the second voltage. In this embodiment of the invention, the end times of the first voltage segment for at least two electrodes 211 are staggered, and the driving current provided by the driving circuit of the liquid crystal prism panel to the at least two electrodes 211 at different times reduces the value of the driving current provided by the driving circuit and avoids the occurrence of instantaneously excessive driving current.

[0042] For example, at least two electrodes 211 include a first electrode E1 and a second electrode E2. Taking the first electrode E1 and the second electrode E2 as examples, the first end time is when the absolute value of the voltage on the first electrode E1 is at the end of the first voltage segment, and the second end time is when the absolute value of the voltage on the second electrode E2 is at the end of the first voltage segment. The first end time and the second end time are different.

[0043] Optionally, refer to Figure 3 , Figure 6 or Figure 7 Electrodes 211 in the same electrode group 21 include the i-th electrode, the j-th electrode, and the k-th electrode, which are arranged sequentially along the arrangement direction of the electrodes 211, where i < j < k, and i, j, and k are positive integers. The absolute voltage value on the i-th electrode is at the end of the first voltage segment after the absolute voltage value on the j-th electrode is at the end of the first voltage segment, and the absolute voltage value on the k-th electrode is at the end of the first voltage segment after the absolute voltage value on the j-th electrode is at the end of the first voltage segment. The time periods when the absolute voltage values ​​on the i-th, j-th, and k-th electrodes are in the first voltage segment overlap. The i-th and k-th electrodes are located near the edge of the electrode group 21, and the j-th electrode is located near the middle of the electrode group 21. For multiple electrodes 211 in the same electrode group 21, the electrode 211 near the edge of the electrode group 21 is at the end of the first voltage segment, and the electrode 211 located near the middle of the electrode group 21 is at the end of the first voltage segment later than the electrode 211 located near the middle of the electrode group 21.

[0044] For example, the i-th electrode is the first electrode E1, the j-th electrode is the eighth electrode E8, and the k-th electrode is the sixteenth electrode E16. The absolute value of the voltage on the eighth electrode E8 at the end of the first voltage segment is after the end of the first voltage segment. The absolute value of the voltage on the sixteenth electrode E16 at the end of the first voltage segment is after the absolute value of the voltage on the eighth electrode E8.

[0045] Optionally, refer to Figure 3 , Figure 6 or Figure 7Within the same electrode group 21, along the arrangement direction of the electrodes 211, the absolute voltage values ​​on multiple electrodes 211 at the end time of the first voltage segment gradually advance and then gradually delay. For multiple electrodes 211 in the same electrode group 21, the closer the electrode 211 is to the edge of the electrode group 21, the later its end time of the first voltage segment; the closer the electrode 211 is to the center of the electrode group 21, the earlier its end time of the first voltage segment. The electrodes 211 on both sides of the electrode group 21 end their first voltage segment later, and as they move towards the center of the electrode group 21, their end time of the first voltage segment gradually advances. The electrodes 211 at the edge of the electrode group 21 end their first voltage segment later than the electrodes 211 at the center of the electrode group 21.

[0046] Optionally, refer to Figure 7 The electrode group 21 includes an i-th electrode and a j-th electrode. The i-th electrode is located near the edge of the electrode group 21, and the j-th electrode is located near the middle of the electrode group 21. The duration of the i-th electrode in the first voltage segment is longer than that of the j-th electrode, and the duration of the i-th electrode in the first voltage segment overlaps with that of the j-th electrode. i and j are positive integers. The start time of the i-th electrode in the first voltage segment is earlier than that of the j-th electrode. The end time of the i-th electrode in the first voltage segment is later than that of the j-th electrode. In this embodiment of the invention, the duration of the first voltage segment for the electrode 211 closer to the middle of the electrode group 21 is within the duration of the first voltage segment for the electrode 211 farther from the middle of the electrode group 21, thereby minimizing the duration of adjacent electrodes 211 at different voltages, reducing the duration of voltage differences between adjacent electrodes 211, and reducing the duration of adverse effects caused by the transverse electric field.

[0047] For example, the i-th electrode can be one of the first electrode E1 to the fourth electrode E4, or the thirteenth electrode E13 to the sixteenth electrode E16. The j-th electrode can be one of the fifth electrode E5 to the twelfth electrode E12. i and j are different. For example, the i-th electrode is the first electrode E1, and the duration of the absolute voltage value on the first electrode E1 being in the first voltage segment is t1; the j-th electrode is the eighth electrode E8, and the duration of the absolute voltage value on the eighth electrode E8 being in the first voltage segment is t8, where t1 is greater than t8. The time period of the first electrode E1 being in the first voltage segment covers the time period of the eighth electrode E8 being in the first voltage segment. Alternatively, the i-th electrode is the fifteenth electrode E15, and the duration of the absolute voltage value on the fifteenth electrode E15 being in the first voltage segment is t15; the j-th electrode is the eighth electrode E8, and the duration of the absolute voltage value on the eighth electrode E8 being in the first voltage segment is t8, where t15 is greater than t8. The time period of the fifteenth electrode E15 being in the first voltage segment covers the time period of the eighth electrode E8 being in the first voltage segment. Alternatively, the i-th electrode is the sixteenth electrode E16, and the duration of the absolute voltage value on the sixteenth electrode E16 being in the first voltage segment is t16. The j-th electrode is the eighth electrode E8, and the duration of the absolute voltage value on the eighth electrode E8 being in the first voltage segment is t8. t16 is greater than t8. The time period during which the sixteenth electrode E16 is in the first voltage segment covers the time period during which the eighth electrode E8 is in the first voltage segment.

[0048] Optionally, refer to Figure 3 , Figure 6 or Figure 7 At least one electrode 211 has opposite voltage polarities in the first voltage segment within two adjacent first time periods T. The voltage polarity of the at least one electrode 211 is positive in one first time period T and negative in the other adjacent first time period T. This reversal of voltage polarity on the at least one electrode 211 within two adjacent first time periods T prevents the liquid crystal molecules in the liquid crystal layer 203 from becoming polarized due to prolonged exposure to the same voltage polarity. Furthermore, this reversal of voltage polarity on the at least one electrode 211 within two adjacent first time periods T also prevents impurity ions in the liquid crystal layer 203 from continuously accumulating towards the electrode 211 or towards the opposing electrode 212, thus improving the operational stability of the liquid crystal prism panel.

[0049] For example, the driving signal applied to the same electrode 211 is an AC signal. In two adjacent first time periods T, the driving signal in one first time period T includes a positive voltage, and the driving signal in the other first time period T includes a negative voltage. In multiple first time periods T, the driving signal is alternately set to include a positive voltage and a negative voltage; that is, the driving signal in one first time period T includes a positive voltage, the driving signal in the next first time period T includes a negative voltage, the driving signal in the next first time period T includes a positive voltage, and the driving signal in the next first time period T includes a negative voltage. For example, the voltage of the first voltage segment on the first electrode E1 to the sixteenth electrode E16 includes a first voltage and a third voltage, the first voltage and the third voltage having equal values ​​but opposite polarities. The first voltage is a positive voltage, and the third voltage is a negative voltage. For any one of the first electrodes E1 to the sixteenth electrode E16, the first voltage and the third voltage are respectively located in two adjacent first time periods T.

[0050] Optionally, the duration of the first time period T is greater than or equal to 10 ms and less than or equal to 20 ms. The first voltage segment on each electrode 211 drives the electrode 211 at a frequency of 50 to 100 Hz.

[0051] Figure 8 This is a driving timing diagram for another liquid crystal prism panel provided in an embodiment of the present invention; see reference. Figure 1 and Figure 8 At least one electrode 211 has two voltages of the same polarity but different magnitudes within the same first time period T. Therefore, the state of the liquid crystal molecules in the liquid crystal layer 203 can be more precisely controlled by using the two voltages of the electrode 211 within the first voltage period. Furthermore, by setting the duration and / or the percentage of duration of the two voltages of the same polarity but different magnitudes within the first voltage period, the start and end times of the first voltage period can be adjusted, thus allowing for more flexible positioning of the start and end times.

[0052] For example, refer to Figure 8 The first electrode E1, within the same first time period T, has a first voltage segment with voltage values ​​V and V1, both of which are positive. Voltage value V1 is greater than voltage value V. Alternatively, the first electrode E1, within the same first time period T, has a first voltage segment with voltage values ​​-V and -V1, both of which are negative. Voltage value -V1 is less than voltage value -V.

[0053] Figure 9 This is a driving timing diagram for another liquid crystal prism panel provided in an embodiment of the present invention; see reference. Figure 1 and Figure 9 The electrode group 21 includes M electrodes 211, and the absolute values of the voltages on the M electrodes 211 include a first voltage segment; the first electrode to the Nth electrode have a voltage of the Lth. If M is an even number, in the electrode group 21, the Pth electrode to the th electrode have a voltage of the Fth; the period during which the first electrode to the Nth electrode are at the Lth voltage overlaps with the period during which the Pth electrode to the th electrode are at the Fth voltage. The periods during which the first electrode to the Nth electrode are at the Lth voltage overlap, and the periods during which the Pth electrode to the th electrode are at the Fth voltage overlap. The absolute value of the Lth voltage is greater than the absolute value of the Fth voltage. P is less than or equal to . If M is an odd number, in the electrode group 21, the Pth electrode to the th electrode have a voltage of the Fth; the period during which the first electrode to the Nth electrode are at the Lth voltage overlaps with the period during which the Pth electrode to the th electrode are at the Fth voltage; the periods during which the first electrode to the Nth electrode are at the Lth voltage overlap, and the periods during which the Pth electrode to the th electrode are at the Fth voltage overlap. 1 < N < P < M, and N, P, and M are positive integers. P is less than or equal to . In an embodiment of the present invention, the first electrode to the Nth electrode are close to the edge position of the electrode group 21, and the average voltage of the first electrode to the Nth electrode is relatively large. The Pth electrode to the th electrode are close to the middle position of the electrode group 21, and the average voltage of the Pth electrode to the th electrode is relatively small; or, the Pth electrode to the th electrode are close to the middle position of the electrode group 21, and the average voltage of the Pth electrode to the th electrode is relatively small. Thus, for the electrodes that require a larger average voltage, a larger voltage value is applied, so as to reduce the length of the first time period T and increase the voltage refresh frequency of each electrode 211.

[0054] Exemplarily, the first voltage segment includes the Lth voltage and / or the Fth voltage, and the absolute value of the Lth voltage and / or the absolute value of the Fth voltage is within the first voltage segment. The Lth voltage or the Fth voltage can be the first voltage. Or, the Lth voltage is not equal to the first voltage, and the Fth voltage is not equal to the first voltage.

[0055] For example, with M=16, N=2, and P=7, the first electrode E1 and the second electrode E2 have a voltage of the Lth degree within the first voltage range, and the seventh electrode E7 and the eighth electrode E8 have a voltage of the Fth degree within the first voltage range. The absolute value of the Lth voltage is greater than the absolute value of the Fth voltage. In other embodiments, with M=16, N=4, and P=5, the first electrode E1 to the fourth electrode E4 have a voltage of the Lth degree within the first voltage range, and the fifth electrode E5 to the eighth electrode E8 have a voltage of the Fth degree within the first voltage range. The absolute value of the Lth voltage is greater than the absolute value of the Fth voltage.

[0056] For example, refer to Figures 1-9 Within the first time period T, the number of time segments t0 in which the absolute value of the voltage of at least one electrode 211 is within the first voltage segment is one. That is, within the first time period T, there is one pulse in which the absolute value of the voltage of the at least one electrode 211 is within the first voltage segment. Within the first time period T, a voltage with an absolute value within the first voltage segment is continuously applied to the at least one electrode 211 without frequent voltage switching, providing sufficient time for the electrode 211 to charge to the preset voltage and reducing the risk of undercharging.

[0057] Figure 10 This is a schematic diagram of the circuit structure of a display device provided in an embodiment of the present invention; see reference. Figure 10 The display device also includes a driving circuit 30, which includes multiple driving units ED. Each driving unit ED includes a transistor. The first electrode of the transistor receives a driving voltage signal 31, the second electrode of the transistor is electrically connected to an electrode 211, and the gate of the transistor receives a control signal 32. When the effective level of the control signal 32 controls the transistor to turn on, the driving voltage signal 31 received by the first electrode of the transistor is transmitted to the electrode 211 through the turned-on transistor. The voltage in the first voltage segment includes a first voltage, and the transistor includes a first transistor M1. The driving voltage signal 31 received by the first electrode of the first transistor M1 includes the first voltage (the value of the first voltage is, for example, ). Figure 10 (V in the text). When the effective level of the control signal 32 controls the first transistor M1 to turn on, the first voltage received by the first electrode of the first transistor M1 is transmitted to the electrode 211 electrically connected to the second electrode of the first transistor M1 through the turned-on first transistor M1.

[0058] For example, the multiple driving units ED include a first driving unit ED1, a second driving unit ED2, ..., a sixteenth driving unit ED16. The control signal 32 received by the gate of the first transistor M1 in the first driving unit ED1 is the first sub-signal E1+ of the first unit; the control signal 32 received by the gate of the first transistor M1 in the second driving unit ED2 is the first sub-signal E2+ of the second unit; ..., the control signal 32 received by the gate of the first transistor M1 in the sixteenth driving unit ED16 is the first sub-signal E16+ of the sixteenth unit. The first sub-signal E1+ to the first sub-signal E16+ of the sixteenth unit control the on / off state of the first transistor M1 in the first driving unit ED1 to the sixteenth driving unit ED16, respectively.

[0059] Optionally, refer to Figure 10 The transistor also includes a second transistor M2, whose first terminal receives a second voltage (the value of the second voltage is, for example, ). Figure 10 (0 in the first voltage segment) The absolute values ​​of the voltage and the second voltage are different. The second terminal of the second transistor M2 is electrically connected to the second terminal of the first transistor M1. When the first transistor M1 is turned on and the second transistor M2 is turned off, the first voltage is transmitted to the electrode 211; when the first transistor M1 is turned off and the second transistor M2 is turned on, the second voltage is transmitted to the same electrode 211.

[0060] For example, the driving unit ED includes a first transistor M1 and a second transistor M2. The control signal 32 received by the gate of the second transistor M2 in the first driving unit ED1 is the first unit second sub-signal E1off; the control signal 32 received by the gate of the second transistor M2 in the second driving unit ED2 is the second unit second sub-signal E2off; ..., the control signal 32 received by the gate of the second transistor M2 in the sixteenth driving unit ED16 is the sixteenth unit second sub-signal E16off. The second transistor M2 in the first driving unit ED1 to the sixteenth driving unit ED16 is turned on or off via the first unit second sub-signal E1off to the sixteenth unit second sub-signal E16off.

[0061] Optionally, refer to Figure 10 The first voltage segment also includes the absolute value of a third voltage, which is located within the first voltage segment. The third voltage is equal in value to the first voltage but has opposite polarity. The transistor also includes a third transistor M3, whose first terminal receives the third voltage (the value of which is, for example, ). Figure 10In the transistor M1, the second terminal of the third transistor M3 is electrically connected to the second terminal of the first transistor M1. The second terminal of the third transistor M3 is also electrically connected to the second terminal of the second transistor M2. When the first transistor M1 is on and the second transistor M2 and the third transistor M3 are off, a first voltage is transmitted to electrode 211. When the first transistor M1 and the third transistor M3 are off and the second transistor M2 is on, a second voltage is transmitted to the same electrode 211. When the first transistor M1 and the second transistor M2 are off and the third transistor M3 is on, a third voltage is transmitted to the same electrode 211.

[0062] For example, the driving unit ED includes a first transistor M1, a second transistor M2, and a third transistor M3. The control signal 32 received by the gate of the third transistor M3 in the first driving unit ED1 is the first unit third sub-signal E1-; the control signal 32 received by the gate of the third transistor M3 in the second driving unit ED2 is the second unit third sub-signal E2-; ..., the control signal 32 received by the gate of the third transistor M3 in the sixteenth driving unit ED16 is the sixteenth unit third sub-signal E16-. The first unit third sub-signal E1- through the sixteenth unit third sub-signal E16- respectively control the on / off state of the third transistor M3 in the first driving unit ED1 through the sixteenth driving unit ED16.

[0063] Optionally, refer to Figure 10 The first terminals of the first transistor M1 in the multiple driving units ED are electrically connected. Thus, a first voltage is provided to the first terminals of the first transistor M1 in the multiple driving units ED through a common voltage terminal. Further, the first terminals of the second transistor M2 in the multiple driving units ED are electrically connected. Thus, a second voltage is provided to the first terminals of the second transistor M2 in the multiple driving units ED through a common voltage terminal. The first terminals of the third transistor M3 in the multiple driving units ED are electrically connected. Thus, a third voltage is provided to the first terminals of the third transistor M3 in the multiple driving units ED through a common voltage terminal.

[0064] For example, the first electrode of the first transistor M1 in the first driving unit ED1 to the sixteenth driving unit ED16 is electrically connected, the first electrode of the second transistor M2 in the first driving unit ED1 to the sixteenth driving unit ED16 is electrically connected, and the first electrode of the third transistor M3 in the first driving unit ED1 to the sixteenth driving unit ED16 is electrically connected.

[0065] Figure 11 This is a driving timing diagram for another liquid crystal prism panel provided in an embodiment of the present invention; see reference. Figure 10 and Figure 11Taking an N-type transistor as an example. In other embodiments, at least some of the transistors may also be P-type transistors. During the period when the first sub-signal E1+ of the first unit is high, the second sub-signal E1off and the third sub-signal E1- of the first unit are low. In the first driving unit ED1, the first transistor M1 is turned on, the second transistor M2 and the third transistor M3 are turned off, and the first voltage ( Figure 10 The voltage (V) is applied to the first electrode E1 through the conducting first transistor M1. During the period when the second sub-signal E1off of the first unit is high, the first sub-signal E1+ and the third sub-signal E1- of the first unit are low. In the first driving unit ED1, the second transistor M2 is turned on, the first transistor M1 and the third transistor M3 are turned off, and the second voltage (V) is applied to the first electrode E1. Figure 10 The 0 in the signal is applied to the first electrode E1 through the conducting second transistor M2. During the period when the third sub-signal E1- of the first unit is high, the second sub-signal E1off and the first sub-signal E1+ of the first unit are low. The third transistor M3 is turned on, the first transistor M1 and the second transistor M2 are turned off, and the third voltage ( Figure 10 The -V in the middle is applied to the first electrode E1 through the conducting third transistor M3.

[0066] Similarly, during the period when the first sub-signal E2+ of the second unit is high, the second sub-signal E2off of the second unit and the third sub-signal E2- of the second unit are low. In the second driving unit ED2, the first transistor M1 is turned on, the second transistor M2 and the third transistor M3 are turned off, and the first voltage ( Figure 10 The voltage (V) is applied to the second electrode E2 through the conducting first transistor M1. During the period when the second sub-signal E2off of the second unit is at a high level, the first sub-signal E2+ of the second unit and the third sub-signal E2- of the second unit are at a low level. In the second driving unit ED2, the second transistor M2 is turned on, the first transistor M1 and the third transistor M3 are turned off, and the second voltage (V) is applied to the second electrode E2. Figure 10 The 0 in the signal is applied to the second electrode E2 through the conducting second transistor M2. During the period when the third sub-signal E2- of the second unit is high, the second sub-signal E2off of the second unit and the first sub-signal E2+ of the second unit are low. The third transistor M3 is turned on, the first transistor M1 and the second transistor M2 are turned off, and the third voltage ( Figure 10The -V signal is applied to the second electrode E2 through the conducting third transistor M3. Since the high-level periods of the first sub-signal E1+ of the first unit and the high-level periods of the first sub-signal E2+ of the second unit can be controlled independently, the high-level periods of the second sub-signal E1off of the first unit and the high-level periods of the second sub-signal E2off of the second unit can be controlled independently, the high-level periods of the third sub-signal E1- of the first unit and the high-level periods of the third sub-signal E2- of the second unit can be controlled independently, and the voltage waveforms on the first electrode E1 and the second electrode E2 can be controlled independently, it can be understood that the voltage waveforms from the first electrode E1 to the sixteenth electrode E16 can be controlled independently, and the voltage waveforms on each electrode 211 in the electrode group 21 can be controlled independently. Therefore, the driving circuit 30 can achieve, for example, […]. Figure 3 , Figure 6 or Figure 7 The timing sequence is shown.

[0067] Optionally, refer to Figure 1 The liquid crystal prism panel also includes a liquid crystal layer 203 and a counter electrode 212. The liquid crystal layer 203 comprises multiple liquid crystal molecules and is located between the counter electrode 212 and the electrode 211. The voltage on the counter electrode 212 includes a second voltage. The second voltage is a common voltage. The percentage of time during which the absolute value of the voltage on the electrode 211 is within the first voltage segment within the first time period T is the duty cycle of the electrode 211 within the first time period T. At least two electrodes 211 have different duty cycles within the first time period T.

[0068] For example, the liquid crystal prism panel 20 includes a first substrate 201, a plurality of electrode groups 21 located on one side of the first substrate 201, and a driving circuit 30 located on the first substrate 201.

[0069] Figure 12 This is a schematic diagram of the structure of a display device provided in an embodiment of the present invention; see reference. Figure 12The display device further includes a display panel 100, with a liquid crystal prism panel 200 located on the light-emitting side of the display panel 100. The display panel 100 includes a second substrate 101, and a driving circuit 30 is located on the second substrate 101. The display panel 100 includes multiple pixel driving circuits and multiple sub-pixels 111. The pixel driving circuits provide driving voltage and / or driving current to the sub-pixels 111, thereby controlling the light-emitting state of each sub-pixel 111. The pixel driving circuits are located on the second substrate 101 and include transistors. For example, when a 7T1C circuit is used in the pixel driving circuit, the pixel driving circuit includes 7 transistors. In this embodiment of the invention, the driving circuit 30 is disposed on the second substrate 101, thereby utilizing the same film layer and forming the transistors in the driving circuit 30 and the pixel driving circuit simultaneously in the same process, thus saving process steps.

[0070] The light-emitting side of the display panel 100 is the side of the sub-pixel 111 that is away from the second substrate 101. The display panel 100 can be a liquid crystal display panel, an organic light-emitting display panel, a quantum dot display panel, an electrophoretic display panel, etc.

[0071] Optionally, refer to Figures 10-12 The display device further includes a display panel 100, a display driver board 43, and a liquid crystal prism driver board 42. The liquid crystal prism panel 200 is located on the light-emitting side of the display panel 100. The display driver board 43 is electrically connected to the display panel 100 and is used to provide driving voltage and / or driving current to the display panel 100. The display driver board 43 provides a driving voltage signal 31. The liquid crystal prism driver board 42 is electrically connected to the liquid crystal prism panel 200 and is used to provide driving voltage and / or driving current to the liquid crystal prism panel 200. The liquid crystal prism driver board 42 is electrically connected to the display driver board 43, and the display driver board 43 and / or the liquid crystal prism driver board 42 provide control signals 32.

[0072] For example, refer to Figure 12 The display device also includes an optically transparent adhesive 41 and a touchpad 300. The display panel 100 and the liquid crystal prism panel 200 are bonded together by the optically transparent adhesive 41. The touchpad 300 is located on the side of the liquid crystal prism panel 200 away from the display panel 100, and the touchpad 300 is used to implement touch functionality. The liquid crystal prism panel 200 and the touchpad 300 are bonded together by the optically transparent adhesive 41.

[0073] Figure 13 This is a driving timing diagram for another liquid crystal prism panel provided in an embodiment of the present invention; see reference. Figure 1 and Figure 13Within the first time period T, the number of time segments t0 in which the absolute voltage value of at least two electrodes 211 falls within the first voltage segment is different. In this embodiment, within the first time period T, the number of time segments t0 in which the absolute voltage value of electrode 211 falls within the first voltage segment can be one or at least two. When the number of time segments t0 in which the absolute voltage value of electrode 211 falls within the first voltage segment is at least two, the various time segments t0 in which the absolute voltage value of the same electrode 211 falls within the first voltage segment collectively determine the duration of the absolute voltage value of electrode 211 falling within the first voltage segment.

[0074] For example, refer to Figure 13 The first electrode E1 has one time segment t0 where the absolute value of its voltage falls within the first voltage segment. The second electrode E2 has two time segments t0 where the absolute value of its voltage falls within the first voltage segment. The durations of the two time segments t0 for the second electrode E2 are t21 and t22, respectively. There is a time interval between the two time segments t0 where the voltage of the second electrode E2 is at the second voltage. The duration of the absolute value of the voltage on the second electrode E2 falling within the first voltage segment is t2, and the sum of t21 and t22 is t2. t21 and t22 are either equal or unequal.

[0075] Optionally, within a first time period T, the number of time segments t0 of electrodes 211 located near the center of electrode group 21 is less than the number of time segments t0 of electrodes 211 located near the edge of electrode group 21. Within a first time period T, the duration of time electrodes 211 located near the center of electrode group 21 are in the first voltage segment is less than the duration of time electrodes 211 located near the edge of electrode group 21 are in the first voltage segment. Within a first time period T, the proportion of time electrodes 211 located near the center of electrode group 21 are in the first voltage segment within the first time period T is less than the proportion of time electrodes 211 located near the edge of electrode group 21 are in the first voltage segment within the first time period T.

[0076] Optionally, the electrode group 21 includes M electrodes 211, and the absolute value of the voltage on the M electrodes 211 includes a first voltage segment, where M is a positive integer; multiple time segments t0 have the same duration, and if M is an even number, in the electrode group 21, the first electrode to the first... Each electrode has K1 to Km time segments t0, where K1 to Km gradually decrease; if M is odd, in electrode group 21, the first electrode to the second electrode... Each electrode has K1 to Km time segments t0, with K1 decreasing gradually to Km. In this embodiment of the invention, for multiple electrodes 211 in the same electrode group 21, the electrodes 211 closer to the edge of the electrode group 21 contain more time segments t0 within the first time period T; the electrodes 211 closer to the center of the electrode group 21 contain fewer time segments t0 within the first time period T. The electrodes 211 on both sides of the electrode group 21 contain more time segments t0 within the first time period T, and are oriented towards the center of the electrode group 21, with the number of time segments t0 gradually decreasing within the first time period T.

[0077] Figure 14 This is a driving timing diagram for another liquid crystal prism panel provided in an embodiment of the present invention; see reference. Figure 1 and Figure 14 At least two time segments t0 have different durations. Within the first time period T, the duration of the earlier time segment t0 for the same electrode 211 is longer than the duration of the later time segment t0. The earlier time segment t0 within the first time period T has a longer duration, while the later time segment t0 within the first time period T has a shorter duration. By rapidly and stably driving the electrode 211 through the earlier time segment t0 within the first time period T, the target display is achieved. The display duration is continuously refined through the later time segments t0 within the first time period T. This improves the display effect of the display device.

[0078] Optionally, refer to Figures 1-14 The voltage in the first voltage segment is the absolute value of the driving voltage of the liquid crystal prism panel 200. The absolute value of the driving voltage of the liquid crystal prism panel 200 is located within the first voltage segment. The voltage in the first voltage segment is not a common voltage; there is a voltage difference between electrode 211 and the counter electrode 212. The longitudinal electric field formed by electrode 211 and the counter electrode 212 can drive the liquid crystal molecules to rotate, thereby modulating the beam transmission direction of the prism unit 210.
