[0076] Detailed description

[0077] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0078] With the rapid development of stereoscopic display technology, there is an increasing demand for stereoscopic display devices. Among the many technologies that enable three-dimensional stereoscopic display, glasses-free stereoscopic display is highly favored in the field of three-dimensional stereoscopic display because it does not require viewers to wear glasses.

[0079] Naked-eye 3D display technology is mainly divided into two categories: reproducing binocular parallax and original light field. The principle of reproducing binocular parallax is to allow the left and right eyes to receive two views with parallax respectively, and the two views are combined in the brain to produce a 3D effect. Therefore, by performing some processing on the screen, the image with parallax is mapped onto the left and right eyes respectively, thus producing a 3D image.

[0080] The primary method for reproducing binocular parallax is by placing a grating on the front or back of the display panel. This horizontally divides the display panel's pixel units into odd-numbered and even-numbered columns of pixels, providing the viewer's left and right eyes with two distinct images. The parallax effect between the left and right eye images creates depth of field, resulting in a stereoscopic display effect. Gratings come in two types: obstruction-type and beam-splitting-type. Obstruction-type gratings are further divided into black-and-white parallax barrier gratings and liquid crystal slit gratings, while beam-splitting gratings include lenticular physical lenses and switchable liquid crystal lenses. Switchable liquid crystal lenses are further divided into three types: switchable resin-type lenticular liquid crystal lenses, switchable polarizing liquid crystal lenses, and switchable electrode-type liquid crystal lenses.

[0081] This disclosure provides a liquid crystal lens, as shown in FIG1, comprising: a lens region LA and a non-lens region NLA located on at least one side of the lens region LA. The lens region LA is capable of transmitting incident light and acting as a lens for the incident light. The non-lens region NLA is located, for example, around the lens region LA.

[0082] As shown in Figures 2 and 3, the liquid crystal lens includes: a substrate SUB; a first metal layer M1 disposed on one side of the substrate SUB, including multiple metal lines JX located in the non-lens region NLA; and a transparent conductive layer TL disposed on the side of the first metal layer M1 away from the substrate SUB, including multiple transparent electrodes DJ located in the lens region LA, and multiple electrode leads YX located in the non-lens region NLA, wherein the orthogonal projections of the electrode leads YX and the metal lines JX on the substrate SUB have an overlapping region OL.

[0083] Since the orthographic projections of electrode lead YX and metal line JX on the substrate SUB overlap in region OL, and electrode lead YX is located on the side of metal line JX away from the substrate SUB, there is a risk of breakage at the ramp position of electrode lead YX and metal line JX.

[0084] To address the aforementioned issues, as shown in Figures 2 and 3, the liquid crystal lens further includes a second metal layer M2 disposed on the surface of the transparent conductive layer TL near and / or away from (as shown in Figures 2 and 3) the first metal layer M1, including a reinforcing pattern BQ located in the non-lens region NLA. In the orthographic projection onto the substrate SUB, the reinforcing pattern BQ overlaps with the electrode lead YX at least in the overlapping region OL, and the reinforcing patterns BQ that overlap with different electrode leads YX are separated from each other and insulated from each other.

[0085] By setting a reinforcing pattern BQ at the intersection of electrode lead YX and metal wire JX, the reinforcing pattern BQ can reinforce electrode lead YX. Even if electrode lead YX breaks at the location of the climbing metal wire JX, the broken electrode leads YX can be connected through the reinforcing pattern BQ, thereby ensuring that electrode lead YX can transmit electrical signals normally.

[0086] As shown in Figure 2, in the direction perpendicular to the substrate SUB, the transparent conductive layer TL and the second metal layer M2 are disposed adjacent to each other, meaning that no other film layer is disposed between the transparent conductive layer TL and the second metal layer M2. The connection between the electrode lead YX and the reinforcing pattern BQ is a direct overlap, without the need for vias HL. Furthermore, the second metal layer M2 can be located on the side of the transparent conductive layer TL closer to the substrate SUB, or it can be located on the side of the transparent conductive layer TL away from the substrate SUB (as shown in Figure 2). This disclosure will use the example of the second metal layer M2 being located on the side of the transparent conductive layer TL away from the substrate SUB for illustration.

[0087] As shown in Figure 2, when the second metal layer M2 is located on the side of the transparent conductive layer TL facing away from the substrate SUB, the first metal layer M1 → passivation layer PVX → transparent conductive layer TL → second metal layer M2 can be formed sequentially on the substrate SUB. When the second metal layer M2 is located on the side of the transparent conductive layer TL close to the substrate SUB, the first metal layer M1 → passivation layer PVX → second metal layer M2 → transparent conductive layer TL can be formed sequentially on the substrate SUB.

[0088] For example, as shown in Figure 2, the thickness of the reinforcing pattern BQ can be greater than or equal to the thickness of the electrode lead YX. The thickness of the reinforcing pattern BQ is, for example, greater than or equal to 200 angstroms.

[0089] For example, the material of the second metal layer M2 may include one or more metal materials such as Mo, Al, Ti, Cu, and Ag, and multiple materials may be stacked.

[0090] The liquid crystal lens disclosed herein is a switchable electrode type liquid crystal lens.

[0091] In some embodiments, as shown in FIG4, in the orthographic projection on the substrate SUB, the reinforcing patterns BQ that overlap with the same electrode lead YX and with different metal lines JX are interconnected as a single structure.

[0092] In other embodiments, as shown in FIG5, in the orthographic projection on the substrate SUB, the reinforcing patterns BQ that overlap with the same electrode lead YX and with different metal lines JX are separated from each other.

[0093] For example, as shown in FIG5, in the orthographic projection on the substrate SUB, the gap between two adjacent reinforcing patterns BQ that overlap with the same electrode lead YX is located within the gap between two adjacent metal lines JX. Furthermore, the gap between two adjacent reinforcing patterns BQ that overlap with the same electrode lead YX can be centrally located within the gap between two adjacent metal lines JX.

[0094] In some embodiments, as shown in FIG4 or FIG6, the overlapping region OL includes a first overlapping region OL1. In the orthographic projection on the substrate SUB, the electrode lead YX and the metal line JX located in the first overlapping region OL1 are connected through the via HL. The reinforcing pattern BQ that overlaps with the first overlapping region OL1 completely covers the via HL.

[0095] For example, as shown in Figure 1, the non-lens region NLA includes a bonding region NL1 and a lead region NL2. Figures 3 and 4 show the structure of the lead region NL2. The electrode lead YX located in the lead region NL2 is connected to the transparent electrode DJ at one end near the lens region LA (as shown in Figure 3), and the end away from the lens region LA is connected to the metal wire JX through a via HL in the first overlapping region OL1 (as shown in Figure 4), and the reinforcing pattern BQ completely covers the via HL.

[0096] Figure 6 shows the structure of the bonding area NL1. The bonding area NL1 includes multiple pins. Each pin is composed of a metal line JX and an electrode lead YX stacked in the bonding area NL1. The metal line JX and the electrode lead YX constituting the pin are connected by a via HL in the first overlapping area OL1, and the reinforcing pattern BQ completely covers the via HL.

[0097] As shown in Figure 1, the pin PIN located in the bonding area NL1 is connected to the metal wire JX located in the lead area NL2. The pin PIN is also connected to the printed circuit board through the flexible circuit board, and the printed circuit board provides voltage input to the transparent electrode.

[0098] For example, as shown in Figure 6, the multiple pins located in the bonding area NL1 include active pins PIN1 and dummy pins PIN2. A dummy pin PIN2 is provided between two adjacent active pins PIN1, and the dummy pin PIN2 serves as a spacer and support. Active pins PIN1 are connected to the metal wire JX, while dummy pins PIN2 are not connected to the metal wire JX.

[0099] As shown in Figure 7, in the orthographic projection on the substrate SUB, the boundary of the reinforcing pattern BQ covering the via HL extends outward by a predetermined distance M relative to the boundary of the via HL. The design value of the predetermined distance M can satisfy the following relationship:

[0100] Where a1 is the tolerance of 1 / 2 the width of via HL, b1 is the tolerance of 1 / 2 the width of reinforcement pattern BQ, c1 is the overlap control value of via HL and metal line JX, and d1 is the overlap control value of reinforcement pattern BQ and metal line JX.

[0101] In practical implementation, the width of the reinforcing pattern BQ covering the via HL can be designed as the sum of the via HL width and 2*M. For example, as shown in Figure 7, the horizontal width of the reinforcing pattern BQ covering the via HL = the horizontal width of the via HL + 2*M1, and the vertical width of the reinforcing pattern BQ covering the via HL = the vertical width of the via HL + 2*M2.

[0102] Where M1 is the preset horizontal distance, when calculating M1, a1 is the tolerance of the horizontal width of 1 / 2 via HL, b1 is the tolerance of the horizontal width of 1 / 2 reinforcement pattern BQ, c1 is the horizontal overlap control value of via HL and metal line JX, and d1 is the horizontal overlap control value of reinforcement pattern BQ and metal line JX. M2 is the preset vertical distance, when calculating M2, a1 is the tolerance of the vertical width of 1 / 2 via HL, b1 is the tolerance of the vertical width of 1 / 2 reinforcement pattern BQ, c1 is the vertical overlap control value of via HL and metal line JX, and d1 is the vertical overlap control value of reinforcement pattern BQ and metal line JX.

[0103] For example, as shown in FIG4 or FIG6, in the orthographic projection on the substrate SUB, the reinforcing patterns BQ covering different vias HL are separated from each other, that is, the reinforcing patterns BQ that overlap with different vias HL are separated from each other.

[0104] For example, as shown in FIG6, the metal wire JX constituting the pin and the electrode lead YX are connected through multiple vias HL in the first overlapping area OL1. The reinforcing patterns BQ covering different vias HL are separated from each other, and the multiple reinforcing patterns BQ are arranged along the extension direction of the pin.

[0105] For example, as shown in FIG4 or FIG6, in the orthographic projection on the substrate SUB, the reinforcing pattern BQ that overlaps with the first overlapping region OL1 is located within the range of the metal line JX. This can reduce the risk of short circuits between adjacent traces.

[0106] In some embodiments, as shown in Figures 1 and 8, the lead region NL2 includes a first lead region 10. Multiple reinforcing patterns BQ located in the first lead region 10 are divided into multiple reinforcing groups BZ. Each reinforcing group BZ includes multiple reinforcing patterns BQ. The reinforcing pattern BQ located in a reinforcing group BZ includes multiple block patterns BK arranged along a first direction f1 and multiple strip patterns BT arranged along a second direction f2. One end of the block pattern BK near the lens region LA is connected to the strip pattern BT. In the orthographic projection on the substrate SUB, the block pattern BK covers the connection via HL between the metal line JX and the electrode lead YX.

[0107] For example, as shown in Figure 8a, the end of the strip pattern BT away from the lens area LA is connected to the block pattern BK, and the end closer to the lens area LA extends to the side of the multiple metal lines JX near the lens area LA.

[0108] For example, as shown in Figure 8a, a plurality of block patterns BK located in a reinforcement group BZ include a first block pattern BK1 and a second block pattern BK2, wherein the first block pattern BK1 is located on the side of the second block pattern BK2 near the lens region LA.

[0109] For example, as shown in Figure 8a, the plurality of reinforcement groups BZ include a first reinforcement group BZ1 and a second reinforcement group BZ2 arranged adjacent to each other. The block pattern BK of the first reinforcement group BZ1 is located on the side of the block pattern BK of the second reinforcement group BZ2 away from the lens area LA. The end of the block pattern BK of the second reinforcement group BZ2 away from the first reinforcement group BZ1 is connected to the strip pattern BT. The first block pattern BK1 in the second reinforcement group BZ2 is located on the side of the second block pattern BK2 close to the first reinforcement group BZ1.

[0110] As shown in Figure 8a, the distance between the block pattern BK of the second reinforcement group BZ2 and the lens area LA is smaller than the distance between the block pattern BK of the first reinforcement group BZ1 and the lens area LA, that is, the block pattern BK in the second reinforcement group BZ2 is closer to the lens area LA.

[0111] For example, as shown in Figure 8a, the plurality of strip patterns BT in the first reinforcing group BZ1 includes a bent strip pattern BTW disposed near the second reinforcing group BZ2. The bent strip pattern BTW includes a bent portion WZ, which bends away from the second reinforcing group BZ2. The first block pattern BK1 in the second reinforcing group BZ2 and the bent portion WZ overlap with different areas of the same metal wire JX. The bent portion WZ of the bent strip pattern BTW in the first reinforcing group BZ1 is used to avoid the first block pattern BK1 in the second reinforcing group BZ2.

[0112] For example, as shown in Figure 8a, multiple block patterns BK located in a reinforcing group BZ are arranged at equal intervals along a first direction f1, and multiple strip patterns BT are arranged at equal intervals along a second direction f2.

[0113] For example, as shown in Figure 8a, the first reinforcing group BZ1 includes multiple bent strip patterns BTW, which include a first bent strip pattern BTW1 and a second bent strip pattern BTW2. The second bent strip pattern BTW2 is located on the side of the first bent strip pattern BTW1 away from the second reinforcing group BZ2. In the second direction f2, the width of the bent portion WZ of the second bent strip pattern BTW2 is less than or equal to the width of the bent portion WZ of the first bent strip pattern BTW1. Figures b and c in Figure 8 show the width w1 of the bent portion WZ of the bent strip pattern BTW in the second direction f2.

[0114] For example, as shown in Figure 8a, in the direction from the second reinforcing group BZ2 to the first reinforcing group BZ1 (the opposite direction of the second direction f2 shown in Figure 8a), the width of the bent portion WZ of the multiple bent strip patterns BTW in the first reinforcing group BZ1 gradually decreases. In Figure 8, the width of the bent portion WZ of the multiple bent strip patterns BTW in the first reinforcing group BZ1 gradually decreases from right to left.

[0115] For example, as shown in Figure 8a, the bent strip pattern BTW also includes a first line segment XD1 extending along the third direction f3. The first line segment XD1 is connected to the end of the bent portion WZ away from the lens area LA. In the orthographic projection on the substrate SUB, the second block pattern BK2 in the second reinforcement group BZ2 and the first line segment XD1 overlap with different areas of the same metal line JX.

[0116] For example, as shown in Figure 8a, the plurality of strip patterns BT in the first reinforcing group BZ1 also includes a straight strip pattern BTZ, which is located on the side of the bent strip pattern BTW away from the second reinforcing group BZ2, and the straight strip pattern BTZ extends along the third direction f3.

[0117] For example, as shown in Figure 8a, in the orthographic projection on the substrate SUB, the straight strip pattern BTZ and the first block pattern BK1 of the second reinforcing group BZ2 overlap with different regions of the same metal line JX, and the straight strip pattern BTZ and the second block pattern BK2 of the second reinforcing group BZ2 overlap with different regions of the same metal line JX.

[0118] For example, as shown in Figure 8a, the third direction f3 is perpendicular to the second direction f2.

[0119] For example, as shown in Figure 8a, the first direction f1 intersects with the second direction f2 and the third direction f3 respectively.

[0120] For example, as shown in Figure 8a, the first reinforcing group BZ1 includes multiple bent strip patterns BTW. The multiple bent strip patterns BTW include an effective bent strip pattern BTWE and a dummy bent strip pattern BTWD. The dummy bent strip pattern BTWD is located on the side of the effective bent strip pattern BTWE that is close to the second reinforcing group BZ2. The effective bent strip pattern BTWE is connected to the block pattern BK and the transparent electrode DJ, respectively. The dummy bent strip pattern BTWD is not connected to the block pattern BK and the transparent electrode DJ, respectively.

[0121] For example, as shown in Figure 8a, the dummy bent strip pattern BTWD does not have a block pattern BK on the side facing away from the lens area LA. Since the dummy bent strip pattern BTWD is located on the side of the effective bent strip pattern BTWE that is close to the second reinforcing group BZ2, the width of the bent portion WZ of the dummy bent strip pattern BTWD is greater than or equal to the width of the bent portion WZ of the effective bent strip pattern BTWE.

[0122] For example, as shown in Figure 8a, in a direction perpendicular to the second direction f2, one end of the dummy bent strip pattern BTWD near the lens region LA terminates at the side of the second block pattern BK2 in the second reinforcement group BZ2 near the lens region LA, and at least one first block pattern BK1 in the second reinforcement group BZ2 is located away from the lens region LA.

[0123] For example, as shown in Figure 8b, the effective bent strip pattern BTWE also includes a second line segment XD2. The second line segment XD2 connects to one end of the bent portion WZ near the lens area LA. The second line segment XD2 is located on the side of the first block pattern BK1 in the second reinforcement group BZ2 near the lens area LA. The first line segment XD1 and the second line segment XD2 are approximately on the same straight line.

[0124] For example, as shown in Figure 8b, the bending portion WZ of the effective bending strip pattern BTWE includes a third line segment XD3, a fourth line segment XD4, and a fifth line segment XD5 connected in sequence. The third line segment XD3 is also connected to the first line segment XD1, and the fifth line segment XD5 is also connected to the second line segment XD2. The extension direction of the fourth line segment XD4 is parallel to the extension directions of the first line segment XD1 and the second line segment XD2. The fourth line segment XD4 is located on the side of the first line segment XD1 and the second line segment XD2 away from the second reinforcing group BZ2.

[0125] For example, as shown in Figure 8c, the bent portion WZ of the dummy bent strip pattern BTWD includes a sixth line segment XD6 and a seventh line segment XD7 connected in sequence. The sixth line segment XD6 is also connected to the first line segment XD1 of the dummy bent strip pattern BTWD. The seventh line segment XD7 is parallel to the extension direction of the first line segment XD1. The seventh line segment XD7 is located on the side of the first line segment XD1 away from the second reinforcement group BZ2. The end of the dummy bent strip pattern BTWD near the lens area LA is the end of the seventh line segment XD7 away from the sixth line segment XD6.

[0126] For example, as shown in Figure 8a, the first line segment XD1 of the illusory bent strip pattern BTWD and a strip pattern BT set near the first reinforcing group BZ1 in the second reinforcing group BZ2 are roughly on the same straight line.

[0127] For example, as shown in Figure 8a, the reinforcing pattern BQ in the reinforcing group BZ also includes a first dummy pattern DP1. In the same reinforcing group BZ, the second block pattern BK2 is located between the first dummy pattern DP1 and the strip pattern BT connected to the second block pattern BK2. The first dummy pattern DP1 and the second block pattern BK2 are separated from each other. The first dummy pattern DP1 and the second block pattern BK2 overlap with different areas of the same metal line JX. Multiple first dummy patterns DP1 are arranged along the first direction f1. As shown in Figure 8a, multiple first dummy patterns DP1 located in the same reinforcing group BZ are arranged at equal intervals along the first direction f1.

[0128] For example, as shown in FIG9, the plurality of reinforcement groups BZ also includes a third reinforcement group BZ3. The third reinforcement group BZ3 is located on the side of the first reinforcement group BZ1 away from the second reinforcement group BZ2 and is disposed adjacent to the first reinforcement group BZ1. The block pattern BK of the third reinforcement group BZ3 is located on the side of the block pattern BK of the first reinforcement group BZ1 close to the lens area LA.

[0129] As shown in Figure 9, the distance between the block pattern BK of the third reinforcement group BZ3 and the lens area LA is smaller than the distance between the block pattern BK of the first reinforcement group BZ1 and the second reinforcement group BZ2 and the lens area LA. That is, the block pattern BK of the third reinforcement group BZ3 is closer to the lens area LA.

[0130] For example, as shown in FIG9, the first reinforcement group BZ1 includes multiple straight strip patterns BTZ. The multiple straight strip patterns BTZ include an effective straight strip pattern BTZE and a dummy straight strip pattern BTZD. The dummy straight strip pattern BTZD is located on the side of the effective straight strip pattern BTZE close to the third reinforcement group BZ3. The effective straight strip pattern BTZE is connected to the block pattern BK and the transparent electrode DJ respectively. The dummy straight strip pattern BTZD is not connected to the block pattern BK and the transparent electrode DJ respectively. The end of the dummy straight strip pattern BTZD close to the lens area LA terminates on the side of the third reinforcement group BZ3 away from the lens area LA.

[0131] By setting a dummy straight strip pattern BTZD, the process environment on both sides of the effective straight strip pattern BTZE set near the third reinforcement group BZ3 is made consistent, avoiding fluctuations in the linewidth of the effective straight strip pattern BTZE, and improving etching uniformity and linewidth uniformity.

[0132] For example, as shown in Figure 9, the dummy straight strip pattern BTZD does not have a block pattern BK on the side facing away from the lens area LA.

[0133] For example, as shown in FIG1, the lead area NL2 includes two first lead areas 10, which are disposed opposite to each other on both sides of the lens area LA, and one of the first lead areas 10 is located between the bonding area NL1 and the lens area LA.

[0134] For example, as shown in FIG1, the first lead area 10 includes a first sub-lead area 11 and a second sub-lead area 12 disposed opposite to each other on both sides of the lens area LA along the column direction fv. The second sub-lead area 12 is located between the bonding area NL1 and the lens area LA, and the first sub-lead area 11 is located on the side of the lens area LA away from the bonding area NL1.

[0135] For example, as shown in FIG1, the non-lens region NLA further includes a third sub-lead region 13 and a fourth sub-lead region 14 disposed opposite each other on both sides of the lens region LA along the row direction fh, and the column direction fv is, for example, perpendicular to the row direction fh. In FIG1, the first sub-lead region 11, the second sub-lead region 12, the third sub-lead region 13 and the fourth sub-lead region 14 are located on different sides of the lens region LA.

[0136] For example, as shown in Figures 8a and 11, the electrode lead YX located in lead region NL2 includes an effective electrode lead YXE, which is connected to the metal line JX and the transparent electrode DJ, respectively. As shown in Figure 8a, the electrode lead YX located in the first lead region 10 also includes a dummy electrode lead YXD, which is not connected to the metal line JX or the transparent electrode DJ, respectively. The block pattern BK2 located in the first lead region 10 covers the connection via HL between the effective electrode lead YXE and the metal line JX.

[0137] For example, in the orthographic projection on the substrate SUB, the electrode leads YX that overlap with the dummy bent strip pattern BTWD, the electrode leads YX that overlap with the first dummy pattern DP1, and the electrode leads YX that overlap with the dummy straight strip pattern BTZD are all dummy electrode leads YXD.

[0138] In some embodiments, as shown in FIG5, the overlapping region OL includes a second overlapping region OL2. In the orthographic projection on the substrate SUB, the electrode lead YX located in the second overlapping region OL2 is insulated from the metal line JX. The reinforcing pattern BQ at least covers the two boundaries of the second overlapping region OL2 that are disposed opposite to each other along the extension direction of the electrode lead YX.

[0139] Since the two boundaries of the second overlapping region OL2, which are set opposite each other along the extension direction of the electrode lead YX, correspond to the climbing position of the electrode lead YX on the metal line JX, the risk of open circuit at this position is relatively high. By setting the reinforcing pattern BQ to at least cover the two boundaries of the second overlapping region OL2, which are set opposite each other along the extension direction of the electrode lead YX, the risk of open circuit at the climbing position of the electrode lead YX on the metal line JX can be effectively reduced.

[0140] For example, as shown in FIG5, in the extension direction of electrode lead YX, the boundary of reinforcing pattern BQ is extended outward by a first distance J relative to the boundary of second overlapping region OL2 in a direction away from second overlapping region OL2. The first distance is greater than or equal to one-third of the gap distance between two adjacent metal lines JX.

[0141] For example, the first distance J satisfies the following relationship:

[0142] Where a2 is the tolerance of the width of 1 / 2 metal line JX (i.e., the line width L3 / 2 of metal line JX), b2 is the tolerance of the length of 1 / 2 reinforcing pattern BQ in the extension direction of electrode lead YX, c2 is the overlap control value of reinforcing pattern BQ and metal line JX in the extension direction of electrode lead YX, and e is the design value of the first distance. When the gap width between two adjacent metal lines JX is 3 micrometers, the design value of the first distance e is, for example, 1 micrometer.

[0143] For example, as shown in FIG5, in the orthographic projection on the substrate SUB, in order to separate the reinforcing patterns BQ that overlap with the same electrode lead YX and overlap with different metal lines JX, the first distance J is less than half of the gap distance between two adjacent metal lines JX.

[0144] In some embodiments, as shown in FIG10, the overlap width w of the reinforcing pattern BQ and the electrode lead YX projected onto the substrate SUB in the extension direction of the metal line JX is greater than or equal to one-tenth of the width L1 of the electrode lead YX. When the width L1 of the electrode lead YX is 3 micrometers, the overlap width w is, for example, greater than or equal to 0.3 micrometers.

[0145] Furthermore, in the extension direction of the metal line JX or in the linewidth direction of the electrode lead YX, the orthogonal projection of the reinforcing pattern BQ on the substrate SUB can completely cover the orthogonal projection of the electrode lead YX on the substrate SUB, which can further reduce the risk of open circuit.

[0146] Since the spacing between reinforcing patterns BQ in actual manufacturing processes has a limit, in order to prevent short circuits between two adjacent reinforcing patterns BQ, the width L2 of the reinforcing pattern BQ in the extension direction of the metal line JX can satisfy the following relationship:

[0147] Where a3 is the tolerance of the width of 1 / 2 electrode lead YX (i.e., the line width L1 of electrode lead YX), b3 is the tolerance of the width of 1 / 2 reinforcement pattern BQ (i.e., L2 / 2), c3 is the overlap control value of electrode lead YX and metal line JX in the extension direction of metal line JX, d3 is the overlap control value of reinforcement pattern BQ and metal line JX in the extension direction of metal line JX, and w is the overlap width of reinforcement pattern BQ and electrode lead YX in the extension direction of metal line JX.

[0148] In some embodiments, as shown in FIG8, in the orthographic projection on the substrate SUB, there are multiple reinforcing patterns BQ that overlap with the effective electrode lead YXE, are located on the same side of the lens region LA and are close to the lens region LA, with the end close to the lens region LA being approximately flush.

[0149] For example, in the first sub-lead region 11 shown in Figure 8, multiple reinforcing patterns BQ are disposed near the lens region LA and overlap with the effective electrode lead YXE. The end near the lens region LA is roughly located on a straight line ZX.

[0150] For example, as shown in FIG11, multiple transparent electrodes DJ are arranged at equal intervals along the fourth direction f4.

[0151] In some embodiments, as shown in FIG11, the transparent conductive layer TL further includes: a plurality of second dummy patterns DP2, the second dummy patterns DP2 having the same extension direction as the transparent electrode DJ, the second dummy patterns DP2 being located between the transparent electrode DJ and the non-lens region NLA near the non-lens region NLA, and an electrode lead YX being disposed between two adjacent second dummy patterns DP2 located on the same side of the lens region LA.

[0152] For example, as shown in FIG11, in the fourth direction f4, the distance between the adjacent second dummy pattern DP2 and the transparent electrode DJ is equal to the distance between two adjacent transparent electrodes DJ.

[0153] By setting a second dummy pattern DP2, the process environment on both sides of the transparent electrode DJ near the non-lens region NLA is made consistent, avoiding fluctuations in the linewidth of the transparent electrode DJ and improving etching uniformity and linewidth uniformity.

[0154] For example, as shown in any of Figures 12 to 20, the metal wire JX located in the lead area NL2 includes the main transmission line CS, the electrode lead YX located in the lead area NL2 includes the adapter lead YX1, and the transparent electrode DJ is connected to the main transmission line CS through at least one adapter lead YX1.

[0155] For example, as shown in any of Figures 12 to 20, multiple transparent electrodes DJ are arranged along the fourth direction f4. These transparent electrodes DJ are divided into multiple electrode groups DZ, each containing the same number of transparent electrodes DJ. The transparent electrodes DJ within the same electrode group DZ are ordered along the fourth direction f4. Transparent electrodes DJ with the same serial number are connected to the same main transmission line CS. Transparent electrodes DJ with different serial numbers are connected to different main transmission lines CS.

[0156] For example, as shown in any of Figures 12 to 20, the non-lens region NLA is provided with three main transmission lines CS, namely main transmission line CS01, main transmission line CS02, and main transmission line CS03. An electrode group DZ includes three transparent electrodes DJ arranged sequentially along the fourth direction f4, numbered X1, X2, and X3, respectively. The transparent electrode DJ numbered X1 is connected to the main transmission line CS01, the transparent electrode DJ numbered X2 is connected to the main transmission line CS02, and the transparent electrode DJ numbered X3 is connected to the main transmission line CS03.

[0157] As shown in any of Figures 12 to 20, the adapter lead YX1, which is directly connected to the transparent electrode DJ, is a continuous integral structure with the transparent electrode DJ. The adapter lead YX1, which is directly connected to the transparent electrode DJ, can be regarded as the part of the transparent electrode DJ extending into the non-lens region NLA.

[0158] For example, the extension direction of the adapter lead YX1, which is directly connected to the transparent electrode DJ, can be parallel to the arrangement direction of the metal trace (as shown in Figure 1), or it can be the same as the extension direction of the transparent electrode DJ (as shown in Figures 12 to 17).

[0159] For example, as shown in Figure 12 or Figure 13, the plurality of transparent electrodes DJ includes a first transparent electrode DJ1 and a second transparent electrode DJ2. The first transparent electrode DJ1 and the second transparent electrode DJ2 are located in different electrode groups DZ and have the same serial number. The length of the first transparent electrode DJ1 is different from the length of the second transparent electrode DJ2. The total length of the adapter lead YX1 connecting the first transparent electrode DJ1 is approximately the same as the total length of the adapter lead YX1 connecting the second transparent electrode DJ2.

[0160] In Figures 12 and 13, the serial number of the first transparent electrode DJ1 and the second transparent electrode DJ2 is X1.

[0161] The total length of the adapter lead YX1 connecting the first transparent electrode DJ1 is the sum of the lengths of the multiple adapter leads YX1 connecting the first transparent electrode DJ1 (two as shown in Figures 12 and 13). The total length of the adapter lead YX1 connecting the second transparent electrode DJ2 is the sum of the lengths of the multiple adapter leads YX1 connecting the second transparent electrode DJ2 (two as shown in Figures 12 and 13).

[0162] In Figures 12 and 13, since the sum of the lengths of the first transparent electrode DJ1 and the two adapter leads YX1 connecting the first transparent electrode DJ1 is different from the sum of the lengths of the second transparent electrode DJ2 and the two adapter leads YX1 connecting the second transparent electrode DJ2, the impedances (RC Loading) of the first transparent electrode DJ1 and the second transparent electrode DJ2 are different, which in turn leads to differences in their charging conditions.

[0163] To reduce the impedance difference between different transparent electrodes DJ, as exemplarily shown in any of Figures 14 to 20, multiple transparent electrodes DJ include a third transparent electrode DJ3 and a fourth transparent electrode DJ4. The third transparent electrode DJ3 and the fourth transparent electrode DJ4 are located in different electrode groups DZ and have the same serial number. The length of the third transparent electrode DJ3 is greater than or equal to the length of the fourth transparent electrode DJ4, and the total length of the adapter lead YX1 connecting the third transparent electrode DJ3 is less than or equal to the total length of the adapter lead YX1 connecting the fourth transparent electrode DJ4. This reduces the impedance difference between the third transparent electrode DJ3 and the fourth transparent electrode DJ4, improving charging consistency.

[0164] In Figures 14 to 20, the serial number of the third transparent electrode DJ3 and the fourth transparent electrode DJ4 is X1.

[0165] The total length of the adapter lead YX1 connecting to the third transparent electrode DJ3 is the sum of the lengths of the multiple adapter leads YX1 connecting to the third transparent electrode DJ3. The total length of the adapter lead YX1 connecting to the fourth transparent electrode DJ4 is the sum of the lengths of the multiple adapter leads YX1 connecting to the fourth transparent electrode DJ4.

[0166] To ensure that the impedances of different transparent electrodes DJ are the same, for example, as shown in Figure 14 or Figure 15, the sum of the total length of the adapter lead YX1 connecting the third transparent electrode DJ3 and the length of the third transparent electrode DJ3 is approximately equal to the sum of the total length of the adapter lead YX1 connecting the fourth transparent electrode DJ4 and the length of the fourth transparent electrode DJ4.

[0167] For example, as shown in Figures 12 to 15, multiple main transmission lines CS located on the same side of the lens region LA are arranged along the direction from the lens region LA to the non-lens region NLA.

[0168] The electrode lead YX shown in Figures 14 and 15 has a relatively simple design, but the left and right borders are quite wide.

[0169] To reduce the width of the left and right bezels, for example, as shown in Figure 16 or Figure 17, the main transmission line CS includes a first main transmission line CS1 located in the first sub-lead area 11 and the second sub-lead area 12, and a second main transmission line CS2 located in the third sub-lead area 13 and the fourth sub-lead area 14. Multiple first main transmission lines CS1 are arranged along the direction from the lens area LA to the non-lens area NLA. The second main transmission line CS2 includes an eighth segment XD8, a ninth segment XD9, and a tenth segment XD10 connected in sequence. The eighth segment XD8 and the tenth segment XD10 extend along the column direction fv. The eighth segment XD8 is located on the side of the tenth segment XD10 closer to the lens area LA. The eighth segment XD8 is also connected to the first main transmission line CS1.

[0170] For example, as shown in Figure 16 or Figure 17, in the third sub-lead area 13, the ninth line segment XD9 is located on the side of the eighth line segment XD8 and the tenth line segment XD10 near the second sub-lead area 12; in the fourth sub-lead area 14, the ninth line segment XD9 is located on the side of the eighth line segment XD8 and the tenth line segment XD10 near the first sub-lead area 11. This makes full use of the space in the third sub-lead area 13 and the fourth sub-lead area 14, which is beneficial for reducing the width of the third sub-lead area 13 and the fourth sub-lead area 14 along the row direction fh.

[0171] For example, as shown in Figure 16 or Figure 17, in the third sub-lead area 13, the end of the eighth segment XD8 near the first sub-lead area 11 is connected to the first main transmission line CS1 located in the first sub-lead area 11, and the end of the eighth segment XD8 near the second sub-lead area 12 is connected to the end of the tenth segment XD10 near the second sub-lead area 12 via the ninth segment XD9.

[0172] For example, as shown in Figure 16 or Figure 17, in the fourth sub-lead area 14, the end of the eighth segment XD8 near the second sub-lead area 12 is connected to the first main transmission line CS1 located in the second sub-lead area 12, and the end of the eighth segment XD8 near the first sub-lead area 11 is connected to the end of the tenth segment XD10 near the first sub-lead area 11 via the ninth segment XD9.

[0173] It should be noted that a ninth segment XD9 can be set between the eighth segment XD8 and the tenth segment XD10 (as shown in Figures 16 and 17), or multiple ninth segments XD9 can be set to be connected to each other. The extension directions of different ninth segments XD9 can be the same or different.

[0174] For example, as shown in Figure 16 or Figure 17, the angle between the extension direction of the multiple transparent electrodes DJ and the row direction fh is an acute angle, and the opening of the acute angle faces the third sub-lead area 13.

[0175] For example, as shown in Figure 16 or Figure 17, the adapter lead YX1 connecting the eighth line segment XD8 and the transparent electrode DJ extends in the same direction as the transparent electrode DJ; the adapter lead YX1 connecting the ninth line segment XD9 and the transparent electrode DJ extends in the same direction as the transparent electrode DJ.

[0176] For example, as shown in Figure 16 or Figure 17, the adapter lead YX1 connecting the tenth line segment XD10 and the transparent electrode DJ is at least partially different from the extending direction of the transparent electrode DJ. This helps to further reduce the width of the left and right borders.

[0177] For example, in Figure 16, for the adapter lead YX11 in the third sub-lead area 13, starting from the connection point O1 between the adapter lead YX11 and the transparent electrode DJ, the adapter lead YX11 first extends along the extension direction of the transparent electrode DJ, and then the adapter lead YX11 bends along the column direction Fv toward the side closer to the tenth line segment XD10 until it overlaps with the tenth line segment XD10.

[0178] For example, in Figure 16, for the adapter lead YX12 in the third sub-lead area 13, starting from the connection point O2 between the adapter lead YX12 and the transparent electrode DJ, the adapter lead YX12 first extends along the extension direction of the transparent electrode DJ to the side of the tenth segment XD10 away from the lens area LA and the side of the ninth segment XD9 away from the tenth segment XD10. Then, the adapter lead YX12 bends along the column direction Fv toward the side closer to the tenth segment XD10. Finally, the adapter lead YX12 bends along the row direction Fh toward the side closer to the tenth segment XD10 until it overlaps with the tenth segment XD10.

[0179] For example, as shown in any of Figures 12 to 17, one end of the transparent electrode DJ is connected to the main transmission line CS via an adapter lead YX1.

[0180] For example, as shown in any of Figures 18 to 20, the metal wire JX located in the lead area NL2 also includes a transfer line ZJ. One end of the transparent electrode DJ is connected to the main transmission line CS through multiple transfer leads YX1, and two adjacent transfer leads YX1 are connected through the transfer line ZJ.

[0181] For example, as shown in Figure 18, the end of the transparent electrode DJ5 near the third sub-lead region 13 is connected to the main transmission line CS located in the first sub-lead region 11 via a series of transition leads YX13, transition transmission line ZJ, transition leads YX13, transition transmission line ZJ, and transition leads YX13. That is, the end of the transparent electrode DJ5 near the third sub-lead region 13 is connected to the main transmission line CS via three transition leads YX1, and any two adjacent transition leads YX1 are connected via a single transition transmission line ZJ.

[0182] For example, as shown in Figure 18, the end of the transparent electrode DJ6 near the third sub-lead region 13 is connected to the main transmission line CS located in the first sub-lead region 11 via a transition lead YX14, a transition transmission line ZJ, and another transition lead YX14. That is, the end of the transparent electrode DJ6 near the third sub-lead region 13 is connected to the main transmission line CS via two transition leads YX1, and the two transition leads YX1 are connected by a transition transmission line ZJ.

[0183] For example, as shown in any of Figures 18 to 20, the number of adapter leads YX1 connected between one end of the transparent electrode DJ and the main transmission line CS is not equal to the number of adapter leads YX1 connected between the other end of the transparent electrode DJ and the main transmission line CS.

[0184] For example, as shown in Figure 18, the number of transition leads YX1 connected between the end of the transparent electrode DJ5 near the first sub-lead area 11 and the main transmission line CS is 3, and the number of transition leads YX1 connected between the end of the transparent electrode DJ5 near the second sub-lead area 12 and the main transmission line CS is 1. The number of transition leads YX1 connected between the end of the transparent electrode DJ6 near the first sub-lead area 11 and the main transmission line CS is 2, and the number of transition leads YX1 connected between the end of the transparent electrode DJ6 near the second sub-lead area 12 and the main transmission line CS is 1.

[0185] For example, as shown in any of Figures 18 to 20, the number of adapter leads YX1 connected between one end of the transparent electrode DJ and the main transmission line CS can be equal to the number of adapter leads YX1 connected between the other end of the transparent electrode DJ and the main transmission line CS.

[0186] For example, as shown in Figure 18, the number of transition leads YX1 connected between the end of the transparent electrode DJ0 near the first sub-lead area 11 and the main transmission line CS in the first sub-lead area 11 is 1, and the number of transition leads YX1 connected between the end of the transparent electrode DJ0 near the second sub-lead area 12 and the main transmission line CS in the second sub-lead area 12 is also 1.

[0187] For example, as shown in any of Figures 18 to 20, the extension directions of different adapter leads YX1 connected between one end of the transparent electrode DJ and the main transmission line CS can be the same, and the extension directions of different adapter transmission lines ZJ can be the same, which helps to reduce the size of the left and right frame.

[0188] In some embodiments, as shown in any of Figures 12, 14, 16, 18 and 20, the metal lines JX located on different sides of the lens region LA are interconnected to form a closed structure.

[0189] In other embodiments, as shown in any of Figures 13, 15, 17 and 19, the metal lines JX disposed on opposite sides of the lens region LA are separated from each other.

[0190] For example, as shown in any of Figures 13, 15, 17 and 19, the metal wire JX located in the first sub-lead area 11 is disconnected from the metal wire JX located in the second sub-lead area 12, and the metal wire JX located in the third sub-lead area 13 is disconnected from the metal wire JX located in the fourth sub-lead area 14.

[0191] For example, as shown in Figure 22, the transparent electrode DJ is a strip with a certain tilt angle θ relative to the column direction fv. This tilt angle θ can be greater than 0° and less than or equal to 30°, and further can be less than or equal to 10°. The specific value of this tilt angle can be determined in conjunction with the display panel, and can be determined to be an angle without moiré patterns.

[0192] For example, as shown in Figure 22, the transparent electrodes DJ are designed periodically. For instance, an electrode group DZ includes K transparent electrodes DJ, and an electrode group DZ constitutes a lens. The linewidth and line spacing of the transparent electrodes DJ are W and S, respectively. Theoretically, the more transparent electrodes DJ a lens contains, the finer the control and the better the effect; that is, the smaller the values ​​of W and S, the better. Considering process limitations, W and S can be set to 2–4 μm.

[0193] For example, as shown in Figure 22, two adjacent electrode groups DZ share a transparent electrode DJ, such as the two electrode groups DZ on the left sharing the (K+1)th transparent electrode DJ.

[0194] In Figures 12 to 20, K = 3, and different transparent electrodes DJ in an electrode group DZ are connected to different main transmission lines CS.

[0195] For example, as shown in FIG21, a substrate SUB and a first metal layer M1, a transparent conductive layer TL and a second metal layer M2 (not shown in FIG21) stacked on one side of the substrate SUB constitute an array substrate JB1. The liquid crystal lens also includes an opposing substrate JB2 and a liquid crystal layer LC disposed between the array substrate JB1 and the opposing substrate JB2. The substrate SUB is disposed away from the liquid crystal layer LC.

[0196] For example, the liquid crystal lens has multiple driving modes, such as ECB mode and ADS mode, with the transparent electrode DJ serving as the driving electrode. In ECB mode, as shown in Figures 21a and 21b, the transparent electrode DJ and the common electrode COM are respectively disposed on opposite sides of the liquid crystal layer LC, with the transparent electrode DJ located on one side of the array substrate JB1 and the common electrode COM located on the opposite side of the opposing substrate JB2. The transparent electrode DJ can be a single-layer structure (as shown in Figure 21a) or a double-layer structure (as shown in Figure 21b).

[0197] In the dual-layer structure, as shown in Figure 21b, the transparent electrode DJ includes an upper transparent electrode DJU and a lower transparent electrode DJD stacked together, with the orthographic projections of the upper transparent electrode DJU and the lower transparent electrode DJD on the substrate SUB alternating. The dual-layer structure allows for voltage control of the liquid crystal at any location, resulting in finer and smoother control and superior performance. Furthermore, the dual-layer structure facilitates the extreme thinning of the transparent electrode DJ, mitigating defects caused by open circuits in the transparent electrode DJ and improving the 3D display effect.

[0198] In ECB mode, the opposing substrate JB2 includes an opposing substrate CD and a common electrode COM disposed on the side of the opposing substrate CD near the liquid crystal layer LC. The common electrode COM is, for example, a continuous structure across the entire surface.

[0199] In ADS mode, as shown in Figures 21c and 21d, the transparent electrode DJ and the common electrode COM are both located on the same side of the liquid crystal layer LC. For example, both the transparent electrode DJ and the common electrode COM are located on one side of the array substrate JB1, and the common electrode COM is stacked between the transparent electrode DJ and the substrate SUB. The common electrode COM can be a strip structure (as shown in Figure 21c) or a continuous structure covering the entire surface (as shown in Figure 21d).

[0200] As shown in Figure 23, assuming we are doing an N-viewpoint design, the number of horizontal viewpoints is N. H The number of vertical viewpoints is Nv, N ​​= N H *Nv.

[0201] As shown in Figure 24, the liquid crystal lens can be equivalently represented as a fixed prism, based on the design of an equivalent fixed prism. The distance between adjacent viewpoints is Wv, the pixel width Px along the row direction fh of the display panel is , the optimal viewing distance is S, the interpupillary distance is L, the prism focal length is f, the placement height is H (as shown in Figure 25), the prism radius of curvature is R, the prism refractive index is n2, the planarization layer refractive index is n1, the prism arrangement period in the row direction fh is D, and the prism arrangement period in the direction of the transparent electrode DJ is D'. Based on the following relationship:

[0202] H = (n2 - n1) * f

[0203] Where Px and L are known values, and S, N, NH, Nv, n2, n1 and Wv are design values. Based on the above formula, f, H, D and D' can be calculated.

[0204] Then, based on the following relationship between the optical path difference and the prism radius:

[0205] Calculate the optical path difference (OPD) value under this design scheme. Assume the refractive index parameters of the liquid crystal are no and ne. Based on the following relationship:

[0206] OPD=Δn*d, Δn=(ne-no)*η,

[0207] The required cell thickness d of the liquid crystal lens can be calculated. Here, η represents the utilization rate of the liquid crystal refractive index, which can be designed from 60% to 90%, depending on the specific product requirements.

[0208] This disclosure provides a display device, as shown in FIG25. The display device includes: a display panel PNL, and a liquid crystal lens TJ as provided in any embodiment. The liquid crystal lens TJ is located on the light-emitting side of the display panel PNL (as shown in FIG25) or disposed away from the light-emitting side of the display panel PNL.

[0209] The display panel PNL is used to display 2D images, and the display panel PNL and the liquid crystal lens TJ work together to form a 3D display device.

[0210] For example, an eye-tracking device can be set on the light-emitting side of the display module to obtain the current position information of the viewer's eyes in front of the display screen in real time in 3D display mode, and drive the liquid crystal lens TJ according to the position information.

[0211] For example, as shown in FIG23, the display panel PNL includes a plurality of sub-pixels arranged in an array along the row direction fh and the column direction fv, with red sub-pixels, green sub-pixels and blue sub-pixels arranged, for example, along the row direction fh.

[0212] For example, as shown in Figure 25, the display panel PNL and the liquid crystal lens TJ are bonded together using optical adhesive OCA. This can be achieved by bonding the array substrate JB1 of the liquid crystal lens TJ to the display panel PNL (as shown in Figure 25), or by bonding the opposing substrate JB2 of the liquid crystal lens TJ to the display panel PNL, both of which can meet the design requirements.

[0213] In practical implementation, whether a polarizer needs to be added to the side of the liquid crystal lens TJ closest to the display panel PNL depends on the specific structure. When the liquid crystal lens TJ is located on the light-emitting side of the display panel PNL, the transmission axis direction of the polarizer POL2 on the light-emitting side of the display panel PNL can be within 45° to 135°.

[0214] When the PI alignment direction of the substrate (array substrate JB1 as shown in Figure 25) of the liquid crystal lens TJ near the display panel PNL is consistent with the transmission axis of the polarizer POL2 of the display panel PNL near the liquid crystal lens TJ, the polarizer may not be provided on the side of the liquid crystal lens TJ near the display panel PNL.

[0215] When the PI alignment direction of the substrate (array substrate JB1 as shown in Figure 25) of the liquid crystal lens TJ near the display panel PNL has an angle with the transmission axis of the polarizer POL2 of the display panel PNL near the liquid crystal lens TJ (the larger the angle, the greater the transmittance loss, and it is generally recommended that the angle be ≤45°), a polarizer can be provided on the side of the liquid crystal lens TJ near the display panel PNL, and the transmission axis of the polarizer is consistent with the PI alignment direction of the substrate (array substrate JB1 as shown in Figure 25) of the liquid crystal lens TJ near the display panel PNL.

[0216] For example, in the orthographic projection on the substrate SUB, the angle between the transparent electrode DJ and the PI alignment direction of the array substrate JB1 can be less than or equal to 20°, so as to improve the utilization rate of the liquid crystal Δn, improve efficiency, reduce cell thickness, and reduce process difficulty.

[0217] The display device provided in this disclosure can realize a naked-eye 3D display scheme that can switch between 2D and 3D, with no loss of 3D display brightness and a 3D crosstalk-free angle of ≥±20°, as shown in Figure 26.
