Figure 2A is a top view of a windshield display panel according to at least one embodiment of the present invention. Figure 2B is a top view of a front window display panel according to at least one embodiment of the present invention.

Figure 6A is a partially enlarged schematic diagram of region A in Figure 5. Figure 6B is a cross-sectional schematic diagram drawn along section line a-a' in Figure 6A. Figures 7 and 8 are partial schematic diagrams of different steps in the manufacturing method of the display panel according to at least one embodiment of the present invention. Implementation

[0015] In the following text, to clearly present the technical features of the present invention, the dimensions (e.g., length, width, thickness, and depth) of the elements (e.g., layers, films, substrates, and regions) in the drawings will be enlarged proportionally, and the number of some elements may be reduced. Therefore, the description and explanation of the embodiments below are not limited to the number of elements in the drawings or the size and shape of the elements, but should cover the size, shape, and deviations from both caused by actual manufacturing processes and / or tolerances. For example, a flat surface shown in the drawings may have rough and / or non-linear characteristics, and an acute angle shown in the drawings may be rounded. Therefore, the elements presented in the drawings of the present invention are mainly for illustration and are not intended to accurately depict the actual shape of the elements, nor are they intended to limit the scope of the claims of the present invention.

[0016] Secondly, the terms "approximately," "approximately," or "substantially" used in this invention not only cover explicitly stated numerical values ​​and ranges, but also the permissible deviation range understandable to those skilled in the art. This deviation range can be determined by errors generated during measurement, which may arise from limitations of the measurement system or process conditions. For example, two objects (e.g., planes or traces of a substrate) are "substantially parallel" or "substantially perpendicular." "Substantially parallel" and "substantially perpendicular" respectively indicate that the parallelism and perpendicularity between the two objects can include non-parallelism and non-perpendicularity caused by permissible deviation ranges.

[0017] Furthermore, "approximately" can indicate that the value is within one or more standard deviations, such as ±30%, ±20%, ±10%, or ±5%. The terms "approximately," "approximately," or "substantially" used in this invention can be selected based on the optical, etching, mechanical, or other properties to determine an acceptable range of deviations or standard deviations, and do not apply a single standard deviation to all of the aforementioned optical, etching, mechanical, and other properties.

[0018] The spatial relative terms used in this invention, such as "below," "under," "above," and "above," are for the convenience of describing the relative relationship between one element or feature and another, as illustrated in the figures. The true meaning of these spatial relative terms includes other orientations. For example, when the illustration is rotated 180 degrees vertically, the relationship between one element and another may change from "below" or "under" to "above" or "above." Furthermore, the spatial relative descriptions used in this invention should be interpreted in the same way.

[0019] It should be understood that although the present invention may use terms such as "first," "second," and "third" to describe various elements or signals, these elements or signals should not be limited by these terms. These terms are primarily used to distinguish one element from another, or one signal from another. Furthermore, the term "or" as used in the present invention may, as appropriate, include any combination of one or more of the associated listed items.

[0020] Furthermore, the present invention can be implemented or applied through other different specific embodiments, and the details of the present invention can also be combined, modified and changed in various embodiments based on different viewpoints and applications without departing from the concept of the present invention.

[0021] Figure 1 is a schematic diagram of a vehicle 10 with a window display function according to at least one embodiment of the present invention. Referring to Figure 1, the vehicle 10 with the window display function includes a windshield frame 100, a front window frame 200, a windshield display panel 300, a front window display panel 400, and a rearview mirror 500. The front window frame 200 is connected to the windshield frame 100, the windshield display panel 300 is installed in the windshield frame 100, the front window display panel 400 is installed in the front window frame 200, and the rearview mirror 500 is adjacent to the front window display panel 400.

[0022] Figure 2A is a top view of a windshield display panel 300 according to at least one embodiment of the present invention. Figure 2B is a top view of a front window display panel 400 according to at least one embodiment of the present invention. Referring to Figures 2A and 2B, the windshield display panel 300 includes sub-display panels 302 and 304, and the outline and dimensions of the front window display panel 400 are the same as those of the sub-display panels 302 and 304.

[0023] With the above design, the front window display panel 400 and sub-display panels 302 and 304 can be produced using the same photomask and process. The sub-display panels 302 and 304 can then be spliced ​​together to form the windshield display panel 300. This can improve the production efficiency of automotive display panels and reduce the production cost of automotive display panels.

[0024] As shown in Figures 2A and 2B, sub-display panels 302 and 304 include a first driving circuit C1 and a second driving circuit C2 respectively disposed on two adjacent sides E1 and E2 of sub-display panels 302 and 304, and there is a first included angle θ1 between the two adjacent sides E1 and E2 of sub-display panels 302 and 304. The front window display panel 400 includes a third driving circuit C3 and a fourth driving circuit C4 respectively disposed on two adjacent sides E3 and E4 of the front window display panel 400, and there is a second included angle θ2 between the two adjacent sides E3 and E4 of the front window display panel 400, which is substantially the same as the first included angle θ1.

[0025] In some embodiments, the two adjacent sides E1 and E2 of the sub-display panels 302 and 304 are connected to each other at contact P1, and the two adjacent sides E3 and E4 of the front window display panel 400 are connected to each other at contact P2. The distance d1 from contact P1 to the first driving circuit C1 is substantially equal to the distance d3 from contact P2 to the third driving circuit C3, and the distance d2 from contact P1 to the second driving circuit C2 is substantially equal to the distance d4 from contact P2 to the fourth driving circuit C4.

[0026] Furthermore, the order of magnitude of the horizontal radius of curvature of the front window display panel 400 is the same as that of the vertical radius of curvature of the windshield display panel 300, and the order of magnitude of the vertical radius of curvature of the front window display panel 400 is the same as that of the horizontal radius of curvature of the windshield display panel 300. For example, the horizontal radius of curvature of the front window display panel 400 is 30,000R to 50,000R, the vertical radius of curvature of the windshield display panel 300 is 10,000R to 20,000R, and the vertical radius of curvature of the front window display panel 400 is 3,000R to 5,000R, while the horizontal radius of curvature of the windshield display panel 300 is 3,000R to 5,000R. That is, the order of magnitude of the horizontal radius of curvature of the front window display panel 400 and the order of magnitude of the vertical radius of curvature of the windshield display panel 300 are both in the tens of thousands, while the order of magnitude of the vertical radius of curvature of the front window display panel 400 and the order of magnitude of the horizontal radius of curvature of the windshield display panel 300 are both in the thousands.

[0027] By using the above-mentioned radius of curvature design, the sub-display panels 302 and 304, which have the same outline and size as the front window display panel 400, can be smoothly spliced ​​together to form the windshield display panel 300 after rotating about 90 degrees. Therefore, the production efficiency of automotive display panels can be improved and the production cost of automotive display panels can be reduced.

[0028] Referring to Figure 2A, the windshield display panel 300 further includes a carrier plate 306. Sub-display panels 302 and 304 are spliced ​​onto the carrier plate 306 to form the windshield display panel 300, which is installed in the windshield frame 100 of the vehicle 10 with window display function in Figure 1. The windshield display panel 300 has a central area R1, a peripheral area R2 surrounding the central area R1, and an edge area R3 located between the windshield frame 100 and the peripheral area R2.

[0029] In some embodiments, the transmittance of the central area R1 is not less than 70% and the panel operation ratio is not greater than 10%, the transmittance of the peripheral area R2 is not less than 40% and the panel operation ratio is not greater than 30%, the transmittance of the edge area R3 is not greater than 10% and the panel operation ratio is not less than 50%, the pixel per degree value of the central area R1 is less than the pixel per degree value of the peripheral area R2, and the pixel per degree value of the peripheral area R2 is less than the pixel per degree value of the edge area R3.

[0030] Since the central area R1 is the main field of vision for the driver, it needs to have a certain penetration rate. Therefore, the panel illumination ratio and pixel value per degree should not be too large to avoid affecting the driver's observation of the external environment. The outer area R2 and the edge area R3 are gradually away from the main field of vision for the driver. Therefore, the panel illumination ratio and pixel value per degree of the outer area R2 can be greater than that of the central area R1, and the panel illumination ratio and pixel value per degree of the edge area R3 can be even greater than that of the outer area R2, so that the outer area R2 and the edge area R3 can be used to display more complex image information such as lane navigation and instrument panel.

[0031] Please refer to Figure 2B. Since the windshield display panel 300 is formed by splicing sub-display panels 302 and 304, which are manufactured with the same photomask and process as the front window display panel 400, the front window display panel 400 also has the same central area R1, peripheral area R2, and edge area R3 at the same positions as the sub-display panels 302 and 304 in the central area R1, peripheral area R2, and edge area R3 of the windshield display panel 300. The transmittance, panel illumination ratio, and pixel value per degree are the same as those of the central area R1, peripheral area R2, and edge area R3 of the windshield display panel 300, and will not be described again here.

[0032] Furthermore, the windshield display panel 300 and the front window display panel 400 are stretchable in the central area R1 and the outer area R2, but non-stretchable in the edge area R3. For example, as shown in Figure 2B, since the angle of the front window frame may differ for different vehicle models, one of the two adjacent sides E3 and E4 of the front window display panel 400 (e.g., E3) can be fixed to the front window frame. Since the central area R1 and the outer area R2 of the front window display panel 400 are stretchable, the second included angle θ2 between the two adjacent sides E3 and E4 is further increased by a stretching angle θ' to match the angle of the vehicle's front window frame. For example, the sum of the second included angle θ2 and the stretching angle θ' can be 90 degrees to 115 degrees. With the aforementioned design, the front window display panel 400 produced with the same photomask and process can be applied to different vehicle models without the need to use different photomasks for production. Therefore, the production efficiency of automotive display panels can be improved and the production cost of automotive display panels can be reduced.

[0033] Figure 3A is a top view of a windshield display panel 300A according to at least another embodiment of the present invention. Figure 3B is a top view of a front window display panel 400A according to at least another embodiment of the present invention. Referring to Figures 3A and 3B, the embodiments of Figures 3A and 3B have most of the same component structures and relative positions as the embodiments of Figures 2A and 2B, and therefore will not be described again here. The difference between the two embodiments is that the windshield display panel 300A of Figure 3A includes sub-display portions 302A and 304A, while the front window display panel 400A of Figure 3B can be formed by cutting sub-display portions 302A and 304A from an additional windshield display panel 300A produced using the same photomask and process.

[0034] In detail, as shown in Figures 3A and 3B, the windshield display panel 300A includes sub-display units 302A and 304A, a first driving circuit C1, and a second driving circuit C2. The first driving circuit C1 and the second driving circuit C2 are respectively disposed on two adjacent sides E1 and E2 of the sub-display units 302A and 304A, and there is a first included angle θ1 between the two adjacent sides E1 and E2 of the sub-display units 302A and 304A. The front window display panel 400A includes a third driving circuit C3 and a fourth driving circuit C4 respectively disposed on two adjacent sides E3 and E4 of the front window display panel 400A, and there is a second included angle θ2 between the two adjacent sides E3 and E4 of the front window display panel 400A, which is substantially the same as the first included angle θ1.

[0035] With the above design, the front window display panel 400A can be formed by cutting the same photomask and manufacturing process of the additional windshield display panel 300A's sub-display parts 302A and 304A, thus improving the production efficiency of automotive display panels and reducing the production cost of automotive display panels.

[0036] In some embodiments, the two adjacent sides E1 and E2 of the sub-display units 302A and 304A are connected to each other at contact P1, and the two adjacent sides E3 and E4 of the front window display panel 400A are connected to each other at contact P2. The distance d1 from contact P1 to the first driving circuit C1 is substantially equal to the distance d3 from contact P2 to the third driving circuit C3, and the distance d2 from contact P1 to the second driving circuit C2 is substantially equal to the distance d4 from contact P2 to the fourth driving circuit C4.

[0037] Sub-display units 302A and 304A contain multiple pixels (not shown), and the first driving circuit C1 and the second driving circuit C2 drive the same pixel among these pixels. As shown in FIG3A, the front window display panel 400A, formed by cutting the sub-display units 302A and 304A of the additional windshield display panel 300A produced by cutting the same photomask and process, can be further cut along the cutting path CP to be installed in the front window frame 200 of the vehicle 10 with window display function in FIG1. ​​It is possible that a portion of the first driving circuit C1 and / or the second driving circuit C2 (i.e., the third driving circuit C3 and / or the fourth driving circuit C4) may be cut off. Therefore, since both the first driving circuit C1 and the second driving circuit C2 can be used to drive the same pixel among these pixels, it can be ensured that after the front window display panel 400A is formed, the pixels of the front window display panel 400A can be driven by at least one of the first driving circuit C1 and the second driving circuit C2 (i.e., the third driving circuit C3 and the fourth driving circuit C4).

[0038] Figure 4A is a top view of the front window display panel 400A and the transparent substrate TS according to at least one embodiment of the present invention. Referring to Figure 4A, the vehicle 10 with the window display function further includes the transparent substrate TS, the front window display panel 400A is disposed on the transparent substrate TS, the front window display panel 400A has an electronic rearview mirror display area DR, and the outer edge of the front window display panel 400A is completely attached to the front window frame 200 of the vehicle 10 with the window display function in Figure 1. In this embodiment, the vehicle 10 with the window display function may not include a solid rearview mirror 500 adjacent to the front window display panel 400A, but the function of the rearview mirror is achieved by the electronic rearview mirror display area DR of the front window display panel 400A.

[0039] Figure 4B is a top view of at least another embodiment of the present invention, showing a front window display panel 400A and a transparent substrate TS. Referring to Figure 4B, the vehicle 10 with the window display function further includes a transparent substrate TS. The front window display panel 400A is disposed on the transparent substrate TS, and the transparent substrate TS is mounted in the front window frame 200 of the vehicle 10 with the window display function shown in Figure 1, and partially overlaps with the front window display panel 400A. Light reflected from the rearview mirror 500 penetrates the portion NP of the transparent substrate TS that does not overlap with the front window display panel 400A, meaning the image of the rearview mirror 500 can be seen by the driver or passenger in the vehicle 10 through the portion NP of the transparent substrate TS that does not overlap with the front window display panel 400A. In this embodiment, the front window display panel 400A can be cut to an appropriate size so that light reflected from the rearview mirror 500 can penetrate the portion NP of the transparent substrate TS, thereby achieving the function of a rearview mirror.

[0040] Figure 5 is a top view of the flexible substrate FS and pixel PX in the central region R1, the peripheral region R2, and the edge region R3 of at least one embodiment of the present invention. Referring to Figure 5, the windshield display panel 300 of Figure 2A, the front window display panel 400 of Figure 2B, the windshield display panel 300A of Figure 3A, and the front window display panel 400A of Figure 3B may include the flexible substrate FS and pixel PX as shown in Figure 5.

[0041] As shown in Figure 5, for the same area, the total area of ​​openings O1 in the central region R1 of the flexible substrate FS is greater than the total area of ​​openings O2 in the peripheral region R2, and the total area of ​​openings O2 in the peripheral region R2 is greater than the total area of ​​openings O2 in the edge region R3. Through the aforementioned design, the central region R1 and the peripheral region R2 can be stretched, while the edge region R3 is not stretchable.

[0042] Furthermore, within the same area, the total number of pixels PX disposed on the flexible substrate FS in the central area R1 is less than the total number of pixels PX disposed on the flexible substrate FS in the peripheral area R2, and the total number of pixels PX disposed on the flexible substrate FS in the peripheral area R2 is less than the total number of pixels PX disposed on the flexible substrate FS in the edge area R3. Through the aforementioned design, the panel illumination ratio and pixel value per degree in the central area R1 can be less than those in the peripheral area R2, and the panel illumination ratio and pixel value per degree in the peripheral area R2 can be less than those in the edge area R3.

[0043] Figure 6A is a partially enlarged schematic diagram of region A in Figure 5. Figure 6B is a cross-sectional schematic diagram drawn along section line a-a' in Figure 6A. Figure 5 can be, for example, the front window display panel 400A of Figure 3B, and the front window display panel 400A has a cutting path CP. Referring to Figures 6A and 6B, the pixels PX disposed on the flexible substrate FS include multiple light-emitting diodes L1, L2, and L3. The front window display panel 400A further includes traces WR disposed on the flexible substrate FS and electrically connected to these light-emitting diodes L1, L2, and L3, and an insulating layer IN corresponding to the cutting path CP covering the edge of the flexible substrate FS. The manufacturing method of the front window display panel 400A shown in Figures 6A and 6B is described below.

[0044] Figures 7 and 8 are partial schematic diagrams of different steps in the manufacturing method of a display panel according to at least one embodiment of the present invention. Specifically, Figures 7(A) and 8(A) are top views of different steps, for example, enlarged views of region B in Figure 6A, while Figures 7(B) and 8(B) are cross-sectional views drawn along sections b-b' and c-c' in Figures 7(A) and 8(A), respectively. First, a mother plate is provided, for example, the windshield display panel 300A of Figure 3A, but the present invention is not limited thereto; mother plates of other forms of display panels are also acceptable. The mother plate is cut to form at least one initial display panel, as shown in Figure 7, the initial display panel having a cut path CP. Next, the cut path CP is etched and cleaned. As shown in Figure 8, after etching and cleaning the cut path CP, an insulating layer IN is formed to cover the cut path CP.

[0045] Since the location adjacent to the cut track CP may leave residue RD caused by the cutting, which may cause a short circuit in the trace WR, the cut track CP is etched and cleaned to remove the residue RD, and an insulating layer IN is formed to cover the cut track CP to avoid the risk of subsequent short circuits. In some embodiments, the insulating layer IN is made of a stretchable material, such as silicone, to complement the stretchability of the flexible substrate FS for use in products that require stretching.

[0046] In some embodiments, the initial display panel has at least one normal pixel PX and at least one edge pixel (not shown). The edge pixel is located between the cutting path CP and the normal pixel PX. The normal pixel includes at least one light-emitting diode L1, L2, and L3, while the edge pixel does not include light-emitting diodes L1, L2, and L3. This design avoids damaging the light-emitting diodes L1, L2, and L3 during cutting, thus preventing excessive residue from affecting yield.

[0047] Light-emitting diodes (LEDs) L1, L2, and L3 can be designated as the first LED L1, the second LED L2, and the third LED L3, emitting different colors of light, respectively. For example, the first LED L1, the second LED L2, and the third LED L3 can be red LEDs, green LEDs, and blue LEDs, respectively. LEDs L1, L2, and L3 can be micro LEDs (μLEDs) or sub-millimeter LEDs (mini LEDs).

[0048] In summary, in the vehicle with window display function according to at least one embodiment of the present invention, the front window display panel and sub-display panel can be produced with the same photomask and process, and then the sub-display panels can be spliced ​​together to form a windshield display panel; or the front window display panel can be formed by cutting the sub-display part of an additional windshield display panel produced with the same photomask and process, thus improving the production efficiency of automotive display panels and reducing the production cost of automotive display panels.

[0049] Furthermore, in the method for manufacturing a display panel according to at least another embodiment of the present invention, since there may be a risk of short circuits caused by residues generated during cutting at the location near the cutting track, the residues are removed by etching and cleaning the cutting track, and an insulating layer is formed to cover the cutting track to avoid the risk of subsequent short circuits.

[0050] Although the present invention has been disclosed above by way of embodiments, it is not intended to limit the present invention.
