[0059] Reference will now be made in detail to exemplary embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings. Whenever possible, the same reference numerals are used in the drawings and the description to refer to the same or like parts.

[0060] The following is an explanation of the implementation of the present disclosure through specific embodiments, and those skilled in the art can easily understand other advantages and effects of the present disclosure from the contents disclosed in this specification. The present disclosure can also be implemented or applied through other different specific embodiments, and the details in the present disclosure can also be modified and changed in various ways for different viewpoints and applications without departing from the spirit of the present disclosure.

[0061] It should be noted that, in this document, unless otherwise specified, "having an element" is not limited to having a single element, but may have one or more elements. In addition, the ordinal numbers used in the specification and claims, such as "first" and "second", to modify the elements of the claims, do not themselves imply or represent any previous ordinal numbers of the claimed elements, nor do they represent the order of one claimed element and another claimed element, or the order in the manufacturing method. The use of these ordinals is only used to make a claimed element with a certain name clearly distinguishable from another claimed element with the same name.

[0062] Certain words are used throughout the specification and claims of this disclosure to refer to specific components. It should be understood by those skilled in the art that electronic equipment manufacturers may refer to the same components by different names. This document is not intended to distinguish between components that have the same function but different names. In this disclosure, words such as "including", "containing", and "having" are open-ended words, so they should be interpreted as "containing but not limited to...". Therefore, when the terms "including", "containing" and / or "having" are used in the description of this disclosure, they specify the existence of corresponding features, areas, steps, operations and / or components, but do not exclude the existence of one or more corresponding features, areas, steps, operations and / or components.

[0063] In the text, the terms "about", "approximately", "substantially", and "roughly" generally mean within 10%, within 5%, within 3%, within 2%, within 1%, or within 0.5% of a given value or range. The numbers given here are approximate numbers, that is, in the absence of specific instructions for "about", "approximately", "substantially", and "roughly", the meanings of "about", "approximately", "substantially", and "roughly" can still be implied. In addition, the terms "range is from a first value to a second value", "range is between a first value and a second value" mean that the range includes the first value, the second value, and other values ​​therebetween.

[0064] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by those skilled in the art to which the present disclosure belongs. It is understood that these terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning consistent with the background or context of the relevant technology and the present disclosure, and should not be interpreted in an idealized or overly formal manner unless specifically defined herein.

[0065] In addition, relative terms such as "below" or "bottom" and "above" or "top" may be used in the embodiments to describe the relative relationship of one element of the drawings to another element. It is understood that if the device of the drawings is turned upside down, the element described on the "below" side will become the element on the "above" side. When a corresponding component (such as a film layer or region) is referred to as "on another component", it can be directly on the other component, or there can be other components between the two. On the other hand, when a component is referred to as "directly on another component", there is no component between the two. In addition, when a component is referred to as "on another component", the two have an up-and-down relationship in the top-view direction, and this component can be above or below the other component, and this up-and-down relationship depends on the orientation of the device.

[0066] In the present disclosure, the distance, width, length, thickness and depth can be measured by an optical microscope, and the distance, width, length, thickness and depth can be measured by a cross-sectional image in an electron microscope, but the present disclosure is not limited thereto. In addition, any two values ​​or directions used for comparison may have a certain error. If the first value is equal to the second value, it implies that there may be an error of about 10% between the first value and the second value; if the first direction is perpendicular to the second direction, the angle between the first direction and the second direction may be between 80 degrees and 100 degrees; if the first direction is parallel to the second direction, the angle between the first direction and the second direction may be between 0 degrees and 10 degrees.

[0081] The third panel 10C may further include a color filter 19-2 (Color Filter, CF), and the color filter 19-2 may be disposed between the insulating layer 163 and the first substrate 17C. In one embodiment, the first panel 10A, the second panel 10B, and the third panel 10C may be used to display light of different wavelength ranges, respectively.

[0082] like Figure 2As shown, the first driving element 2 can be electrically connected to the plurality of first electrodes 11A of the first panel 10A, and can apply a first potential waveform SS to the first electrodes 11A. Similarly (not shown), another first driving element 2 can be electrically connected to the plurality of first electrodes 11B of the second panel 10B, and can apply a first potential waveform SS to the first electrodes 11B. Similarly (not shown), another first driving element 2 can be electrically connected to the plurality of first electrodes 11C of the third panel 10C, and can apply a first potential waveform SS to the first electrodes 11C. In one embodiment, the first driving element 2 can be, for example, a scan driver, but is not limited thereto. The second driving element 3 can be electrically connected to the plurality of second electrodes 12A of the first panel 10A, and can be used to apply a second potential waveform DS to the second electrodes 12A. Similarly (not shown), another second driving element 3 can be electrically connected to the plurality of second electrodes 12B of the second panel 10B, and can be used to apply a second potential waveform DS to the second electrodes 12B. Similarly (not shown), another second driving element 3 can be electrically connected to the plurality of second electrodes 12C of the third panel 10C, and can be used to apply the second potential waveform DS to the second electrodes 12C. In one embodiment, the second driving element 3 can be, for example, a data driver, but is not limited thereto. In one embodiment, the first electrode (11A, 11B and / or 11C) and the second electrode (12A, 12B and / or 12C) in each panel (the first panel 10A, the second panel 10B and / or the third panel 10C) can receive the first potential waveform SS and the second potential waveform DS respectively, and the first potential difference VRMS can be formed between the first potential waveform SS and the second potential waveform DS to generate an electric field (for example, a vertical electric field), and at this time, the cholesterol liquid crystal layer (13A, 13B or 13C) in the pixel P corresponding to the overlap of the first electrode and the second electrode can be adjusted and arranged, for example, by the influence of the electric field. For a pixel P in the first panel 10A, the second panel 10B and / or the third panel 10C, influenced by the first potential difference VRMS between the first potential waveform SS applied to its corresponding first electrode (11A, 11B or 11C) and the second potential waveform DS applied to its corresponding second electrode (12A, 12B or 12C), the arrangement state of the liquid crystal molecules in the cholesterol liquid crystal layer 13 in the corresponding pixel P will change, thereby adjusting the optical state of the first panel 10A, the second panel 10B or the third panel 10C.

[0083] Next, in the embodiment of the present disclosure, a driving method for driving the panel containing the cholesterol liquid crystal layer (13A, 13B or 13C) is proposed. For example, each of the multiple pixels P is operated through multiple operation phases, and the multiple operation phases may include a preparation phase, a selection phase, and an evolution phase, but they are not shown here. In one embodiment, when the screen is to be updated, in the preparation stage, for example, the cholesterol liquid crystals of the pixels that were originally in the bright state (e.g., the reflective state, i.e., the planar state) and the dark state (e.g., the focal conic state) are switched to the homeotropic state arrangement. In the subsequent selection stage, according to whether these pixels are to be switched to the bright state or the dark state, the pixels are switched to the homeotropic state or the transient planar state in this stage. For example, when pixel A is to be switched to the bright state, in the selection stage, pixel A will be switched to the homeotropic state first, and when pixel B is to be switched to the dark state, in the selection stage, pixel B will be switched to the transient planar state first.

[0084] Later in the development stage, according to whether these pixels will be switched to a bright state or a dark state, the pixels will be switched to a vertical state or a focal conic state in this stage. For example, when pixel A is to be switched to a bright state later, in the development stage, pixel A will be switched to a vertical state first. For example, when pixel B is to be switched to a dark state later, in the development stage, pixel B will be switched to a focal conic state first.

[0085] After the voltage is subsequently discharged, the cholesterol liquid crystal in pixel A changes from the vertical state to the planar state, while the cholesterol liquid crystal in pixel B remains in the focal conic state. The above description is a brief description of the basic dynamic driving scheme (DDS).

[0086] In one embodiment, when one of the multiple pixels P operates in the preparation stage, the selection stage and the development stage, the first driving element 2 applies different first potential waveforms SS to the first electrode (11A, 11B or 11C) corresponding to each pixel P, and applies different second potential waveforms DS to the second electrode (12A, 12B or 12C) corresponding to each pixel P, so as to switch the cholesterol liquid crystal in the corresponding pixel to an appropriate state.

[0087] Next, a first driving method of the pixel P according to the present disclosure is described. Figure 3FIG. 1 shows a potential schematic diagram of a first potential waveform SS and a second potential waveform DS of an embodiment of the present disclosure, and please also refer to FIG. Figure 1 and Figure 2 For the convenience of explanation, Figure 3 The first potential waveform SS and the second potential waveform DS received by a pixel P are used as an example for description, and those skilled in the art can infer the situations of other pixels P from this.

[0088] like Figure 3 As shown, in one embodiment, when a pixel P operates in the preparation stage, the selection stage and the development stage, the first driving element 2 can apply different first potential waveforms SS to the first electrode (11A, 11B or 11C) corresponding to the pixel P, and the first potential waveform SS applied in each stage can include at least two of a positive potential +S1 of a first scanning potential, a negative potential -S1 of a first scanning potential, a positive potential +S2 of a second scanning potential, a negative potential -S2 of a second scanning potential, a positive potential +S3 of a third scanning potential and a negative potential -S3 of a third scanning potential. In other words, in any stage of the preparation stage, the selection stage and the development stage, the first potential waveform SS can include at least two scanning potentials, but is not limited thereto.

[0089] In one embodiment, when the pixel P operates in the preparation stage, the selection stage and the development stage, the second driving element 3 can respectively apply different second potential waveforms DS to the second electrode (12A, 12B or 12C) corresponding to the pixel P, and the different second potential waveforms DS applied in each stage can include a positive potential +D1 of the first data potential, a negative potential -D1 of the first data potential, a positive potential +D2 of the second data potential and a negative potential -D2 of the second data potential.

In one embodiment, the absolute value D2 of the second data potential +D2 and the second data potential negative potential -D2 may be greater than the absolute value D1 of the first data potential positive potential +D1 and the first data potential negative potential -D1 (i.e., D2>D1), but not limited thereto. In one embodiment, the absolute value D1 of the positive potential +D1 of the first data potential and the absolute value S1 of the positive potential +S1 of the first scanning potential and the negative potential -S1 of the first scanning potential (D1≠S1) are not equal, but not limited to this. In one embodiment, the absolute value D2 of the positive potential +D2 of the second data potential and the absolute value S3 of the positive potential +S3 of the third scanning potential and the negative potential -S3 of the third scanning potential (i.e., D2≠S3) are not equal, but not limited to this. In one embodiment, the absolute value S2 of the positive potential +S2 of the second scanning potential and the negative potential -S2 of the second scanning potential, the absolute value D1 of the positive potential +D1 of the first data potential and the negative potential -D1 of the first data potential, and the absolute value D2 of the positive potential +D2 of the second data potential and the negative potential -D2 of the second data potential meet the following relationship: S2=(D1+D2) / 2. In one embodiment, the absolute value S3 of the positive potential +S3 of the third scanning potential and the negative potential -S3 of the third scanning potential may be less than 40 volts (V) (S3<40V) or less than or equal to 35V (S3≦35V), or less than or equal to 30V (S3≦30V), and is not limited thereto. In one embodiment, the absolute value S2 of the positive potential +S2 of the second scanning potential and the negative potential -S2 of the second scanning potential may be less than 30V (S2<30V), or less than or equal to 25V (S2≦25V) or less than or equal to 20V (S2≦20V), and is not limited thereto.

[0091] In one embodiment, the absolute value D2 of the positive potential +D2 and the negative potential -D2 of the second data potential may be less than the absolute value S3 of the positive potential +S3 and the negative potential -S3 of the third scan potential (D2 < S3), and is not limited thereto.

In one embodiment, the absolute value D2 of the positive potential +D2 and the negative potential -D2 of the second data potential may be less than 40 V (D2 < 40 V), or less than or equal to 35 V (D2 ≤ 35 V), or less than or equal to 30 V (D2 ≤ 30 V), and is not limited thereto. In one embodiment, the absolute value D1 of the positive potential +D1 and the negative potential -D1 of the first data potential may be less than 30 V (D1 < 30 V) or less than or equal to 25 V (D1 ≤ 25 V), or less than or equal to 20 V (D1 ≤ 20 V), and is not limited thereto.

[0092] Since the potentials applied to the pixel P by the first driving element 2 and the second driving element 3 have positive and negative values, compared with the driving method that only applies positive potential or negative potential, the present disclosure can reduce power consumption, or can extend the service life of the element, and is not limited thereto. In addition, since the potentials applied in the present disclosure have positive and negative potentials, the amplitude of the potential to be applied is smaller (for example, a potential of 0 V to 40 V can be replaced by applying -20 V to 0 V and 0 V to +20 V). Therefore, compared with the driving method that only applies positive potential or negative potential, the number of charges flowing in the present disclosure can be reduced, and the problem of crosstalk can also be reduced.

[0093] In one embodiment, the values ​​of the first data potential D1 applied by the second driving element 3 to the first panel 10A, the second panel 10B and the third panel 10C in different stages may be the same or different.

In one embodiment, the absolute values ​​D2 of the positive potential of the second data potential and the negative potential of the second data potential applied by the second driving element 3 to the first panel 10A, the second panel 10B and the third panel 10C may be the same or different. For example, when the cholesterol liquid crystal layer 13A of the first panel 10A operates in a planar state for reflecting blue light, the cholesterol liquid crystal layer 13B of the second panel 10B operates in a planar state for reflecting green light, and the cholesterol liquid crystal layer 13C of the third panel 10C operates in a planar state for reflecting red light, the absolute value D2 of the positive potential of the second data potential and the negative potential of the second data potential applied to the first panel 10A may be greater than the absolute value D2 of the positive potential of the second data potential and the negative potential of the second data potential applied to the second panel 10B, and the absolute value D2 of the positive potential of the second data potential and the negative potential of the second data potential applied to the second panel 10B may be greater than the absolute value D2 of the positive potential of the second data potential and the negative potential of the second data potential applied to the third panel 10C, that is, D2 (corresponding to the first panel 10A)>D2 (corresponding to the second panel 10B)>D2 (corresponding to the third panel 10C), and is not limited to this.

[0094] In one embodiment, the values ​​of the third scanning potential S3 applied by the first driving element 2 to the first panel 10A, the second panel 10B and the third panel 10C may be the same or different. For example, when the cholesterol liquid crystal layer 13A of the first panel 10A operates in a planar state for reflecting blue light, the cholesterol liquid crystal layer 13B of the second panel 10B operates in a planar state for reflecting green light, and the cholesterol liquid crystal layer 13C of the third panel 10C operates in a planar state for reflecting red light, the absolute value S3 of the positive potential of the third scanning potential and the negative potential of the third scanning potential applied to the second panel 10B can be greater than the absolute value S3 of the positive potential of the third scanning potential and the negative potential of the third scanning potential applied to the third panel 10C, or the absolute value S3 of the positive potential of the third scanning potential and the negative potential of the third scanning potential applied to the second panel 10B can be greater than the absolute value S3 of the positive potential of the third scanning potential and the negative potential of the third scanning potential applied to the first panel 10A, that is, S3 (corresponding to the second panel 10B)>S3 (corresponding to the third panel 10C), or S3 (corresponding to the second panel 10B)>S3 (corresponding to the first panel 10A), and is not limited to this.

[0095] In addition, in one embodiment, the preparation stage, the selection stage and the development stage may each include a high-wave stage and / or a low-wave stage, wherein the high-wave stage and the low-wave stage correspond to different second potential waveforms DS, that is, the second driving element 3 will apply the second potential waveform DS of different waveforms to the second electrode (12A, 12B or 12C) corresponding to whether the current stage belongs to the high-wave stage or the low-wave stage. The second driving element 3 will select the high-wave stage or the low-wave stage in different stages (preparation stage, selection stage and development stage) according to whether the pixel is to be switched to a bright state or a dark state later. When the subsequent pixel is to be switched to a bright state, the second driving element 3 selects the high-wave stage in different stages (preparation stage, selection stage and development stage), and applies the second potential waveform DS in the high-wave stage to the second electrode (12A, 12B or 12C) of the corresponding pixel. When the subsequent pixel is to be switched to the dark state, the second driving element 3 selects the low wave stage in different stages (preparation stage, selection stage and development stage), and applies the second potential waveform DS in the low wave stage to the second electrode 12 (12A, 12B or 12C) of the corresponding pixel. For the convenience of explanation, hereinafter, the second potential waveform DS in the high wave stage is defined as DS_H, and the second potential waveform DS in the low wave stage is defined as DS_L.

[0096] In one embodiment, in the preparation stage, the selection stage and / or the development stage, one cycle of the first potential waveform SS can be divided into a plurality of sub-periods, the plurality of sub-periods do not overlap with each other and have substantially the same timing length.

The positive potential +D1 or negative potential -D1 of the first data potential corresponds to one of the sub-periods Q1 to Q4, respectively, and the positive potential +D2 or negative potential -D2 of the second data potential corresponds to the other of the sub-periods Q1 to Q4, respectively, but not limited thereto. In one embodiment, the positive potential +D1 of the first data potential, the negative potential -D1 of the first data potential, the positive potential +D2 of the second data potential, and the negative potential -D2 of the second data potential can correspond to one of the four sub-periods Q1 to Q4, respectively, to form the second potential waveform DS, but not limited thereto. It should be noted that the sub-periods Q1 to Q4 of the first potential waveform SS can roughly correspond to the sub-periods Q1 to Q4 of the second potential waveform DS. In one embodiment, the operation stage of the pixel P may selectively include a non-address selection stage. Considering that if each pixel P is driven in a passive manner, in the non-address selection stage, the cholesterol liquid crystal layer 13 of each pixel P can, for example, be applied with a small electric field (for example, smaller than the electric field applied in at least one of the other stages, but not limited to this), thereby maintaining the state of the liquid crystal molecules (for example, bright state or dark state), but not limited to this.

[0105] In one embodiment, when the pixel P is operated in the low wave stage of the non-addressing stage, the first potential waveform SS includes the positive potential +S2 of the second scanning potential and the negative potential -S2 of the second scanning potential, the second potential waveform DS_L includes the positive potential +D1 of the first data potential, the negative potential -D1 of the first data potential, the positive potential +D2 of the second data potential and the negative potential -D2 of the second data potential, and the first potential difference VRMS may be VN.

[0107] Therefore, the configurations of the first potential waveform SS and the second potential waveform DS can be understood.

[0108] Next, an example is used to further explain the waveform configuration of the first potential waveform SS and the second potential waveform DS of the present disclosure in detail. Table 2 presents the potentials of the first potential waveform Scan and the second potential waveform DS in the preparation stage, the selection stage, and the development stage with actual numerical values, wherein the above S1 is exemplified by 5V, the above S2 is exemplified by 15V, the above S3 is exemplified by 25V, the above D1 is exemplified by 10V, and the above D2 is exemplified by 20V. Table 2 is presented as follows, but is not limited thereto:

[0109] Table 2

[0110]

[0111] The contents of Table 2 can be roughly applied to the description of Table 1. For example, Table 2 can be regarded as presenting S1-S3 and D1-D2 in Table 1 in numerical form, so the details are not described in detail.

[0112] Figure 4 1 shows a waveform diagram of the first potential waveform, the second potential waveform and the first potential difference in each operation stage of an embodiment of the present disclosure, and please also refer to Figures 1 to 3 .in, Figure 4 It corresponds to the value in Table 2.

[0113] like Figure 4As shown, in the low wave stage and the high wave stage of the preparation stage, the first potential difference VRMS can be 40.31V, but not limited to this. In the low wave stage of the selection stage, the first potential difference VRMS can be 5V, but not limited to this. In the high wave stage of the selection stage, the first potential difference VRMS can be 15V, but not limited to this. In the low wave stage and the high wave stage of the development stage, the first potential difference VRMS can be 15V, but not limited to this. In the low wave stage and the high wave stage of the non-site selection stage, the first potential difference VRMS can be 5V, but not limited to this.

[0114] Then the aforementioned Figure 3 and Figure 4 Based on the example of FIG. 1 , the driving method of the pixel columns and pixel rows formed by a plurality of pixels P is described.

[0115] Figure 5A The timing diagram of potential waveforms corresponding to a plurality of pixel rows Col1 to Col2 and a plurality of pixel columns Row1 to Row4 according to an embodiment of the present disclosure is shown. Figure 5B An embodiment of the present disclosure corresponds to Figure 5A Schematic diagram of driving multiple pixels on or off, where Figure 5B For presenting the schematic state of a plurality of pixels P1-P8 after the electric field is discharged after the development stage is completed and in a steady state, please also refer to Figures 1 to 4 . Figure 5A The pixel columns Row1 to Row4 and the pixel rows Col1 to Col2 composed of a plurality of pixels P are presented. Figure 4 The case of the first potential waveform SS and the second potential waveform DS in .

[0116] In addition, each pixel row Row1 to Row4 can be electrically connected to the first driving element 2, for example (see Figure 2 ), each pixel row Col1-Col2 can be electrically connected to the second driving element 3, for example (please refer to Figure 2 ).

[0117] For ease of explanation, Figure 5A and Figure 5B For example, eight pixels P1 - P8 form four pixel rows Row1 - Row4 and two pixel columns Col1 - Col2 . In practice, the number of pixels, pixel rows and pixel rows may be more or less.

[0118] like Figure 5A As shown, the first driving unit 2 can, for example, sequentially transmit the first potential waveform SS to the pixel rows Row1 to Row4 , and the second driving unit 3 can synchronously transmit the second potential waveform DD to the pixel rows Col1 and Col2 according to whether each pixel is to be in a bright state or a dark state.

[0119] In one embodiment, the pixel rows Row1 to Row4 are operated in the preparation stage (thin lines in the figure), the selection stage (horizontal bars in the figure), and the development stage (bold lines in the figure), for example, but not limited thereto. The timings of the pixel rows Row1 to Row4 being operated in the preparation stage partially overlap, the timings of the pixel rows Row1 to Row4 being operated in the selection stage are, for example, mutually sequential, and the timings of the pixel rows Row1 to Row4 being operated in the development stage partially overlap.

[0120] In one embodiment, in the preparation stage (such as the thin lines in the figure), the first potential waveforms SS respectively applied to the pixel columns Row1 to Row4 may have the same waveform, for example, but are not limited thereto. In the selection stage (such as the horizontal bars in the figure), the first potential waveforms SS respectively applied to the pixel columns Row1 to Row4 may have the same waveform, for example, but are not limited thereto. In the development stage (such as the thick lines in the figure), the first potential waveforms SS respectively applied to the pixel columns Row1 to Row4 may have the same waveform, for example, but are not limited thereto. In different stages (preparation stage, selection stage or development stage), the first potential waveforms SS are, for example, different.

[0121] In one embodiment, the second potential waveform DS applied to the pixel rows Col1 and Col2 may be a second potential waveform DS_H in a high waveform phase or a second potential waveform DS_L in a low waveform phase according to whether the pixel is subsequently switched to a bright state (ON) or a dark state (OFF), but is not limited thereto.

[0122] In one embodiment, the optical state of the pixels P1-P8 in the steady state can be determined by selecting the waveform of the high-wave stage D_H or the low-wave stage D_L as the applied second potential waveform DS in the selection stage. Figure 5A and Figure 5B As shown, in one embodiment, the pixel P1 receives the first potential waveform SS through the pixel column Row1 in the selection phase, and receives the second potential waveform D_H in the high-wave phase through the pixel row Col1, so the pixel P1 can be bright in the steady state (in Figure 5B In the selection phase, the pixel P2 receives the first potential waveform SS through the pixel column Row2 and receives the second potential waveform D_L in the low-wave phase through the pixel row Col1, so the pixel P2 can present a dark state in the steady state (in Figure 5BOFF in the selection stage). Pixel P3 receives the first potential waveform SS through the pixel column Row3 in the selection stage, and receives the second potential waveform D_H in the high wave stage through the pixel row Col1, so the pixel P3 can be in a bright state in a steady state. Pixel P4 receives the first potential waveform SS through the pixel column Row4 in the selection stage, and receives the second potential waveform D_L in the low wave stage through the pixel row Col1, so the pixel P4 can be in a dark state in a steady state. Pixel P5 receives the first potential waveform SS through the pixel column Row1 in the selection stage, and receives the second potential waveform D_H in the high wave stage through the pixel row Col2, so the pixel P5 can be in a bright state in a steady state. Pixel P6 receives the first potential waveform SS through the pixel column Row2 in the selection stage, and receives the second potential waveform D_H in the high wave stage through the pixel row Col2, so the pixel P6 can be in a bright state in a steady state. Pixel P7 receives the first potential waveform SS through pixel column Row3 in the selection stage, and receives the second potential waveform D_L in the low-wave stage through pixel row Col2, so pixel P7 can present a dark state in the steady state. Pixel P8 receives the first potential waveform SS through pixel column Row4 in the selection stage, and receives the second potential waveform DS_L in the low-wave stage through pixel row Col2, so pixel P8 can present a dark state in the steady state. The above-mentioned way of presenting a dark state or a bright state in the steady state is only an example, and can be adjusted according to the desired display image condition.

[0123] In addition, the timing of the potential waveforms corresponding to the pixel rows and pixel columns may also have different implementation aspects. Fig. 6A FIG. 4 shows a timing diagram of potential waveforms corresponding to a plurality of pixel rows Col1 to Col2 and a plurality of pixel columns Row1 to RowN according to another embodiment of the present disclosure. Figure 6B Another embodiment of the present disclosure corresponds to Fig. 6A Schematic diagram of driving multiple pixels on or off, where Figure 6B It is used to present a plurality of pixels P1-PN2, for example, after the electric field is discharged after the development stage is completed and in a steady state. Please also refer to Figures 1 to 5B .also, Figure 6B Can present Fig. 6A Under the driving mode, the optical states of the plurality of pixels P1 to PN2 in a bright state or a dark state in a steady state are not limited thereto. Fig. 6A The embodiment can be generally applied to Figure 5A The following is a description of the embodiments, so only the differences are described.

[0124] exist Fig. 6A In the embodiment, the first panel 10A, the second panel 10B or the third panel 10C may respectively have N pixel columns Row1 to RowN ( Fig. 6AOnly Row1, Row3, Row(N-2), and Row(N) are shown. Each pixel row Row1 to RowN can be electrically connected to the first driving element 2, for example, and N is a positive integer greater than or equal to 4. For convenience of description, Fig. 6A and Figure 6B The example uses eight pixels P1 - P8 to form four pixel rows and two pixel lines Col1 - Col2 as an example. In practice, the number of pixels, pixel rows and pixel columns may be greater.

[0125] like Fig. 6A As shown, the first driving element 2 can asynchronously send the first potential waveform SS corresponding to different stages to the N pixel columns Row1~RowN, and can send the first potential waveform SS corresponding to different stages not according to the arrangement order of the N pixel columns Row1~RowN (for example, the arrangement order in the Y direction). For example, the first driving element 2 can first send the first potential waveform SS to the pixel column Row1, and then the first driving element 2 can send the first potential waveform SS to the pixel column RowN, and then the first driving element 2 can send the first potential waveform SS to the pixel column Row3, and then the first driving element 2 can send the first potential waveform SS to the pixel column Row(N-2), and is not limited to this.

[0126] like Fig. 6A and Figure 6BAs shown, in one embodiment, the pixel P1 receives the first potential waveform SS through the pixel column Row1 in the selection stage, and receives the second potential waveform DS_H in the high wave stage through the pixel row Col1, so the pixel P1 can present a bright state in the steady state. The pixel PN1 receives the first potential waveform SS through the pixel column RowN in the selection stage, and receives the second potential waveform DS_L in the low wave stage through the pixel row Col1, so the pixel PN1 can present a dark state in the steady state. The pixel P3 receives the first potential waveform SS through the pixel column Row3 in the selection stage, and receives the second potential waveform DS_H in the high wave stage through the pixel row Col1, so the pixel P3 can present a bright state in the steady state. The pixel P(N-2)_1 receives the first potential waveform SS through the pixel column Row(N-2) in the selection stage, and receives the second potential waveform DS_L in the low wave stage through the pixel row Col1, so the pixel P(N-2)_1 can present a dark state in the steady state. Pixel P5 receives the first potential waveform SS through pixel column Row1 in the selection stage, and receives the second potential waveform DS_H in the high wave stage through pixel row Col2, so pixel P5 can present a bright state in the steady state. Pixel PN2 receives the first potential waveform SS through pixel column RowN in the selection stage, and receives the second potential waveform DS_H in the high wave stage through pixel row Col2, so pixel PN2 can present a bright state in the steady state. Pixel P7 receives the first potential waveform SS through pixel column Row3 in the selection stage, and receives the second potential waveform DS_L in the low wave stage through pixel row Col2, so pixel P7 can present a dark state in the steady state. Pixel P(N-2)_2 receives the first potential waveform SS through pixel column Row(N-2) in the selection stage, and receives the second potential waveform DS_L in the low wave stage through pixel row Col2, so pixel P(N-2)_2 can present a dark state in the steady state.

[0127] Therefore, the timing of the potential waveforms corresponding to the plurality of pixel rows and the plurality of pixel columns of the first panel 10A, the second panel 10B or the third panel 10C and the optical states in the steady state can be understood.

[0128] The waveform configurations of the first potential waveform SS and the second potential waveform DS of the present disclosure may also have different aspects. Figure 3 , Figure 4 , Table 1 and Table 2, Table 3 presents the potentials of the first potential waveform SS and the second potential waveform DS of another embodiment in the preparation stage, the selection stage and the development stage with actual values, and Figure 7 FIG. 4 shows a waveform diagram of a first potential waveform SS, a second potential waveform DS and a first potential difference VRMS in each operation stage of another embodiment of the present disclosure, wherein Figure 7The values ​​in Table 3 correspond to the values ​​in Table 3, and Table 3 is based on the example of S1 being 5V, S2 being 15V, S3 being 25V, D1 being 10V, and D2 being 20V. Table 3 is presented as follows:

[0129] Table 3

[0130]

[0131] The contents of Table 3 can be roughly applied to the description of Table 2. Figure 7 The content can generally be applied Figure 4 For example, Table 3 and Figure 7 The potentials of the first potential waveform SS and / or the second potential waveform DS in each stage can be compared with those in Table 2 and Figure 4 Same, but Table 3 and Figure 7 The arrangement order of the potentials of the first potential waveform SS and / or the second potential waveform DS in each stage during the sub-periods Q1 to Q4 may be different from that in Table 2 and Figure 4 In addition, although Table 3 and Figure 7 The order of the potentials in Table 2 and Figure 4 , but Table 3 and Figure 7 The first potential difference VRMS of each stage is still the same as Table 2 and Figure 4 The first potential difference VRMS is the same.

[0132] It can be seen from this that the arrangement order of the potentials of the first potential waveform SS and / or the second potential waveform DS of the present disclosure during the sub-periods Q1 to Q4 of each stage can be arbitrarily adjusted according to needs and can have high adaptability.

[0133] In addition to the aforementioned bright state and dark state, the pixel P of the present disclosure can also be used to present a grayscale state. Fig. 8A 1 shows various configurations of the first potential waveform SS and the second potential waveform DS in the selection stage of an embodiment of the present disclosure, which is used to display the potential waveform received by the pixel P when it presents a dark state, a grayscale state and a bright state, and please also refer to Figures 1 to 7 It should be noted that Fig. 8A The values ​​in Table 1 and Table 2 are used as examples. Please refer to Table 2 for the actual potential values ​​described below.

[0134] like Fig. 8AAs shown, in one embodiment, each of the sub-periods Q1 to Q4 can be divided into n parts (for example, the length of one sub-period can be n), where n for each of the sub-periods Q1 to Q4 can be composed of m1 plus m2 (n = m1 + m2), where m1 is, for example, the time length of the second potential waveform DS_L that occupies the low-wave stage in the second potential waveform DS received by the second electrode under each of the sub-periods Q1 to Q4, and m2 is, for example, the time length of the second potential waveform DS_H that occupies the high-wave stage in the second potential waveform DS received by the second electrode under each of the sub-periods Q1 to Q4. The magnitudes of m1 and m2 can be adjusted according to the gray-scale level. When displaying a bright state, m1 is, for example, 0, and m2 = n. When displaying a dark state, m1 is, for example, n, and m2 = 0. When displaying a gray-scale state, m1 and m2 can be designed in the following ways according to the brightness of the gray scale: m1 < m2 or m1 = m2 or m1 > m2.

[0135] For example, in the selection stage, and when desiring to drive the pixel P (displayed in Figure 1 or Figure 2 ) to present a bright state, the second potential waveform DS of all parts in each of the sub-periods Q1 to Q4 selects the second potential waveform DS_H of the high-wave stage, that is, m2 = n, which means Q1 completely corresponds to +D2, Q2 completely corresponds to +D1, Q3 completely corresponds to -D2, Q4 completely corresponds to -D1, but is not limited thereto. In this embodiment, during sub-period Q1, the potential of the first potential waveform SS can be the positive potential +S1 of the first scan potential (for example, +5V), and the potential of the second potential waveform DS_H can be the positive potential +D2 of the second data potential (for example, +20V). During sub-period Q2, the potential of the first potential waveform SS can be the positive potential +S3 of the third scan potential (for example, +25V), and the potential of the second potential waveform DS_H can be the positive potential +D1 of the first data potential (for example, +10V). During sub-period Q3, the potential of the first potential waveform SS can be the negative potential -S1 of the first scan potential (for example, -5V), and the potential of the second potential waveform DS_H can be the negative potential -D2 of the second data potential (for example, -20V). During sub-period Q4, the potential of the first potential waveform SS can be the negative potential -S3 of the third scan potential (for example, -25V), and the potential of the second potential waveform DS_H can be the negative potential -D1 of the first data potential (for example, -10V). Therefore, the first potential difference VRMS (that is, VH) received by the cholesterol liquid crystal layer (13A, 13B, or 13C) of the pixel P (displayed in Figure 1 ) can be, for example, 15V, and thus the pixel P can present a bright state, but is not limited thereto.

[0136] For example, in the selection stage, when the pixel P is to be driven to present a dark state, the second potential waveform DS of all parts in each sub-period Q1 to Q4 can all select the second potential waveform DS_L in the low-wave stage, that is, m1 = n, that is, Q1 completely corresponds to +D1, Q2 completely corresponds to +D2, Q3 completely corresponds to -D1, Q4 completely corresponds to -D2, but is not limited thereto. In one embodiment, during sub-period Q1, the potential of the first potential waveform SS can be the positive potential +S1 (e.g., +5V) of the first scan potential, and the potential of the second potential waveform DS_L can be the positive potential +D1 (e.g., +10V) of the first data potential. During sub-period Q2, the potential of the first potential waveform SS can be the positive potential +S3 (e.g., +25V) of the third scan potential, and the potential of the second potential waveform DS_L can be the positive potential +D2 (e.g., +20V) of the second data potential. During sub-period Q3, the potential of the first potential waveform SS can be the negative potential -S1 (e.g., -5V) of the first scan potential, and the potential of the second potential waveform DS_L can be the negative potential -D1 (e.g., -10V) of the first data potential. During sub-period Q4, the potential of the first potential waveform Scan can be the negative potential -S3 (e.g., -25V) of the third scan potential, and the potential of the second potential waveform DS_L can be the negative potential -D2 (e.g., -20V) of the second data potential. Therefore, the first potential difference VRMS (i.e., VL) received by the cholesteric liquid crystal layer 13 of the pixel P can be, for example, 5V, and thus the pixel P can present a dark state, but is not limited thereto.

[0137] For example, in the selection stage, when driving the pixel P to present a gray-scale state, the second potential waveform DS can be set such that in each sub-period Q1 to Q4, the second electrode can select to receive the positive potential +D1 (the second potential waveform DS_L in the low-wave stage) of the first data potential for a part of the time (e.g., the time length of m1), and select to receive the potential +D2 (the second potential waveform DS_H in the high-wave stage) of the second data potential for a part of the time (e.g., the time length of m2). When displaying a gray-scale state, m1 and m2 can be designed in the following ways according to the brightness of the gray scale: m1 < m2 or m1 = m2 or m1 > m2, but is not limited thereto.

[0138] In one embodiment, during the selection stage, in the sub-period Q1, the potential of the first potential waveform SS may be the positive potential +S1 (e.g., +5V) of the first scanning potential, and the potential of the second potential waveform DS may be the positive potential +D1 (e.g., +10V) of the first data potential during the period m1, and the positive potential +D2 (e.g., +20V) of the second data potential during the period m2. In the sub-period Q2, the potential of the first potential waveform SS may be the positive potential +S3 (e.g., +25V) of the third scanning potential, and the potential of the second potential waveform DS may be the positive potential +D2 (e.g., +20V) of the second data potential during the period m1, and the positive potential +D1 (e.g., +10V) of the first data potential during the period m2. During the sub-period Q3, the potential of the first potential waveform SS may be the negative potential -S1 (e.g. -5V) of the first scanning potential, the potential of the second potential waveform DS may receive the negative potential -D1 (e.g. -10V) of the first data potential during the period of the m1 portion, and the length during the m2 period may be the negative potential -D2 (e.g. -20V) of the second data potential. During the sub-period Q4, the potential of the first potential waveform SS may be the negative potential -S3 (e.g. -25V) of the third scanning potential, the potential of the second potential waveform DS may be the negative potential -D2 (e.g. -20V) of the second data potential during the m1 period, and the length during the m2 period may be the negative potential -D1 (e.g. -10V) of the first data potential, but not limited thereto. Therefore, the first potential difference VRMS received by the cholesterol liquid crystal layer 13 of the pixel P may be, for example, 12.75V, which is between 15V in the bright state and 5V in the dark state, so that the pixel P can present a grayscale state, but not limited thereto. By adjusting the ratio between m1 and m2, the first potential difference VRMS received by the cholesterol liquid crystal layer 13 of the pixel P in the selection stage can be adjusted. The first potential difference VRMS can be selectively adjusted to any suitable potential difference between 15V and 5V (5V≦VRMS≦15V), but is not limited thereto. Next, the configuration of the second potential waveform DS having different potentials during the m1 portion and the m2 portion during the preparation stage, the development stage and the non-site selection stage (such as Fig. 8A configuration in ). Figure 8B Schematic diagrams showing various configurations of the first potential waveform SS and the second potential waveform DS in the preparation stage according to an embodiment of the present disclosure are shown. Figure 8C Schematic diagrams showing various configurations of the first potential waveform SS and the second potential waveform DS in the development stage according to an embodiment of the present disclosure are shown. Fig.8D The first potential waveform SS and the second potential waveform DS of one embodiment of the present disclosure are shown in various configuration diagrams in the non-site selection stage. Fig. 8A The configuration in the figure will not be described in detail.

[0139] like Figure 8B As shown, in the preparation stage, the first potential waveform SS can be the negative potential -S3 (for example, -25V) of the third scanning potential in the sub-period Q1, the first potential waveform SS can be the negative potential -S3 (for example, -25V) of the third scanning potential in the sub-period Q2, the first potential waveform SS can be the positive potential +S3 (for example, +25V) of the third scanning potential in the sub-period Q3, and the first potential waveform SS can be the positive potential +S3 (for example, +25V) of the third scanning potential in the sub-period Q4, regardless of whether the second potential waveform DS is in the high wave stage (DS_H), the low wave stage (DS_L), or the like. Fig. 8A In the driving grayscale state (each sub-period Q1-Q4 has DS_H and DS_L), the first potential difference VRMS received by the pixel P is the same value (for example, 40.31V). It can be seen that the first potential difference VRMS in the preparation stage is not affected by the change in the configuration of the second potential waveform DS.

[0140] like Figure 8C As shown, in the development stage, the first potential waveform SS can be the negative potential -S1 (for example, -5V) of the first scanning potential in the sub-period Q1, the first potential waveform SS can be the negative potential -S1 (for example, -5V) of the first scanning potential in the sub-period Q2, the first potential waveform SS can be the positive potential +S1 (for example, +5V) of the first scanning potential in the sub-period Q3, and the first potential waveform SS can be the positive potential +S1 (for example, +5V) of the first scanning potential in the sub-period Q4, regardless of whether the second potential waveform DS is in the high wave stage (DS_H), the low wave stage (DS_L), or the like. Fig. 8A In the driving grayscale state (each sub-period Q1-Q4 has DS_H and DS_L), the first potential difference VRMS received by the pixel P is the same value (for example, 20.62V). It can be seen that the first potential difference VRMS in the preparation stage is not affected by the change in the configuration of the second potential waveform DS.

[0141] like Fig.8D As shown, in the non-addressing stage, the first potential waveform SS can be the positive potential +S2 (for example, +15V) of the second scanning potential in the sub-period Q1, the first potential waveform SS can be the positive potential +S2 (for example, +15V) of the second scanning potential in the sub-period Q2, the first potential waveform SS can be the negative potential -S2 (for example, -15V) of the second scanning potential in the sub-period Q3, and the first potential waveform SS can be the negative potential -S2 (for example, -15V) of the second scanning potential in the sub-period Q4, regardless of whether the second potential waveform DS is in the high wave stage (DS_H), the low wave stage (DS_L), or the like. Fig. 8AIn the state of driving grayscale state (each sub-period Q1-Q4 has DS_H and DS_L), the first potential difference VRMS received by the pixel P is the same value (for example, 5V, that is, the pixel P can present a dark state). It can be seen that the first potential difference VRMS in the non-site selection stage is not affected by the change in the configuration method of the second potential waveform DS.

[0142] It can be seen that the present disclosure can drive the pixel P to present a dark state, a bright state or a grayscale state by adjusting the second potential waveform DS in the selection phase, and other operation phases can also use the same second potential waveform DS without being affected.

[0143] The first potential waveform SS and the second potential waveform DS of the present disclosure may also have different implementation aspects. Fig. 9 FIG. 1 shows a waveform diagram of a first potential waveform SS and a second potential waveform DS of another embodiment of the present disclosure, and please also refer to FIG. Figures 1 to 8D . Fig. 9 The example can be roughly applied Figure 3 For the purpose of explanation of the examples, the following describes the differences.

[0144] exist Fig. 9 In the embodiment, the absolute value D2 of the positive and negative potentials of the second data potential can be equal to the absolute value S3 of the positive and negative potentials of the third scanning potential, and can be greater than the absolute value D1 of the positive and negative potentials of the first data potential (D2=S3>D1), but is not limited thereto. In addition, the absolute value S2 of the positive and negative potentials of the second scanning potential, the absolute value D1 of the positive and negative potentials of the first data potential, and the absolute value D2 of the positive and negative potentials of the second data potential can still meet the following relationship: S2=(D1+D2) / 2. The absolute value S3 of the positive and negative potentials of the third scanning potential can still be greater than the absolute value S2 of the positive and negative potentials of the second scanning potential, and the absolute value S2 of the positive and negative potentials of the second scanning potential can still be greater than the absolute value S1 of the positive and negative potentials of the first scanning potential (S3>S2>S1), but is not limited thereto. The absolute value D1 of the positive potential and the negative potential of the first data potential and the absolute value S1 of the positive potential and the negative potential of the first scanning potential may still be unequal (D1≠S1).

[0145] Therefore, the types of potentials that the first driving element 2 and the second driving element 3 need to provide can be reduced, but are not limited thereto.

[0146] In addition, as the temperature of the environment changes, the viscosity of the cholesterol liquid crystal layer (13A, 13B and / or 13C) may also change, which also causes the arrangement of the cholesterol liquid crystal molecules to be affected by the size of the electric field and change. For example, the cholesterol liquid crystal molecules may need to be applied with electric fields of different potential differences or the period of application of the electric field must be adjusted to achieve the optical state that should be at the original temperature. Therefore, in one embodiment, the present disclosure can at least adjust the length of the development stage so that the cholesterol liquid crystal layer 13 can still maintain similar brightness or darkness at different temperatures.

[0147] Fig.10 FIG. 1 is a schematic diagram showing the operation of multiple pixel columns of an electronic device 1 according to an embodiment of the present disclosure, and please also refer to FIG. Figures 1 to 9 .

[0148] In one embodiment, the length of the development phase can be adjusted so that the cholesterol liquid crystal layer 13 can present similar brightness at different ambient temperatures. For example, when the temperature is low, the length of the development phase can be selectively extended, and when the temperature is high, the length of the development phase can be selectively shortened, and the invention is not limited thereto. In one embodiment, the length of the development phase can be extended by increasing the number of pixel columns synchronously operating in the development phase, but the invention is not limited thereto.

[0149] In addition, in one embodiment, the first potential difference VE in the development stage can be adjusted at various temperatures so that the cholesterol liquid crystal layer 13 can present the same brightness at different temperatures. For example, when the temperature is low, the first potential difference VE can be selectively increased, and when the temperature is high, the first potential difference VE can be selectively reduced, and the present invention is not limited thereto. Therefore, the electronic device 1 of the present invention can adapt to a variety of ambient temperatures, and is not limited thereto.

[0150] In one embodiment, the present disclosure can at least determine whether a product falls within the protection scope of the present disclosure by observing the presence or absence of components, component configuration, mechanism observation and / or operation mode of the product, but is not limited thereto.

[0151] The details or features of the various embodiments of the present disclosure may be mixed and matched as desired as long as they do not violate the spirit of the invention or conflict with each other.

[0152] Therefore, the driving process of the electronic device disclosed in the present invention can reduce the driving time to achieve fast screen switching, or can reduce the problem of signal crosstalk, or can extend the life of components, or can adapt to a variety of ambient temperatures.

[0153] The above embodiments are merely examples for the convenience of description. The scope of protection claimed by the present disclosure should be based on the claims, rather than being limited to the above embodiments.
