Description

Technical Field

[0001] The present disclosure relates to an optical aiming device, particularly an optical aiming device including a variable aiming point. Background Art

[0002] Conventional target aiming devices (e.g., gun sights) use optical components (e.g., lens groups) to present a aiming pattern superimposed on the center of the field of view. In conventional target aiming devices, the central aiming point has a fixed size, and the size of the aiming point affects the shooting accuracy (measured in minutes of angle, MOA). Conventional target aiming devices cannot change the size of the central aiming point according to different application scenarios. Users need to purchase target aiming devices with different sizes of aiming points, which causes inconvenience in use and increases unnecessary financial expenditures. Therefore, the optical aiming device industry is seeking methods to solve the above issues. Summary of the Utility Model

[0003] An optical aiming device includes a transmissive screen disposed at a first end of the optical aiming device, the transmissive screen including a concave surface, and a display device disposed at a second end of the optical aiming device, configured to project a first pattern alone or project the first pattern and a second pattern simultaneously on the transmissive screen. Wherein the first pattern and the second pattern have different shapes; and the first pattern has a geometric center, and the second pattern radially surrounds the first pattern outward from the geometric center.

[0020] The optical aiming device 100 includes a transmissive screen 120 and a display device 122. The transmissive screen 120 and the display device 122 are disposed on a base 124. The transmissive screen 120 is disposed at a first end of the optical aiming device 100, and the display device 122 is disposed at a second end of the optical aiming device 100. The display device 122 faces the concave surface 120s of the transmissive screen 120, and the light 122r emitted by the display device 122 can be projected onto the concave surface 120s of the transmissive screen 120. The user's eye 100e (which may also be referred to as an observer) can observe the content (e.g., pattern or information 300) projected by the display device 122 on the transmissive screen 120.

[0021] The optical aiming device 100 further includes a control system 125, buttons 126a, 126b, and an environmental sensor 128. The user can change the content projected by the display device 122 via the buttons 126a and 126b. In certain embodiments, when the user presses the button 126a or 126b, the pattern or information 300 projected by the display device 122 on the transmissive screen 120 changes. In certain embodiments, when the user presses the button 126a or 126b, the pattern or information 300 projected by the display device 122 on the transmissive screen 120 changes in shape or size.

[0022] In some embodiments, the control system 125 may change the content projected by the display device 122 in response to signals provided by the environmental sensor 128. In some embodiments, the control system 125 may change the brightness of the display device 122 in response to signals provided by the environmental sensor 128. Accordingly, the brightness of the pattern or information 300 projected by the display device 122 on the transmissive screen 120 may change in response to signals provided by the environmental sensor 128. In some embodiments, the control system 125 may change the contrast of the display device 122 in response to signals provided by the environmental sensor 128. Accordingly, the contrast of the pattern or information 300 projected by the display device 122 on the transmissive screen 120 may change in response to signals provided by the environmental sensor 128.

[0024] The display device 122 may be controlled via the control system 125 to project a pattern (e.g., Figure 2A , 2B the reticle patterns 302, 304, and 306 drawn in FIGS. 2C and Figure 3A , 3B the center aiming points AP-1, AP-2, and AP-3 drawn in FIGS. 3C) on the transmissive screen 120. The display device 122 may project different patterns on the transmissive screen 120 by turning on (or lighting) different portions of the electrodes. Details of the projected patterns will be discussed in subsequent paragraphs.

[0025] Figure 1B A perspective view of an optical aiming device according to certain embodiments of the present disclosure. As Figure 1BAs shown, the display device 122 can be disposed within the base 124 via the holding structure 123. In some embodiments, the holding structure 123 is designed to be adjustable for adjusting the position of the pattern or information 300 on the transmissive screen 120. For example, the user can move the pattern or information 300 along the X-axis direction on the transmissive screen 120 by adjusting the holding structure 123. Similarly, the user can move the pattern or information 300 along the Y-axis direction or Z-axis direction on the transmissive screen 120 by adjusting the holding structure 123. In some embodiments, the clarity of the pattern or information 300 on the transmissive screen 120 can be adjusted by adjusting the holding structure 123.

[0026] As Figure 1B shown, the pattern or information 300 may include a pattern portion 300a and an information portion 300b. The pattern portion 300a may include patterns of different shapes or colors, including but not limited to Figure 2A , 2B , and the aiming cross pattern drawn in 2C. Figure 2A , 2B , and the aiming cross pattern drawn in 2C may include, for example Figure 3A , 3B , and the central aiming point pattern drawn in 3C. The information portion 300b may include various information for the user to refer to when aiming, such as but not limited to at least one of wind speed, ballistic offset, or humidity.

[0027] Figure 2A , 2B and 2C illustrate schematic diagrams of the pattern portion 300a that can be displayed on the transmissive screen 120 according to some embodiments of the present disclosure. Figure 2A shows the aiming cross pattern 302. In some embodiments, the aiming cross pattern 302 may be presented in the same color as a whole. In some embodiments, the aiming cross pattern 302 may also include different colors. The aiming cross pattern 302 includes the central aiming point AP. In the present application, the central aiming point AP has a variable size, which will be discussed in detail in the following paragraphs. Figure 2B shows the aiming cross pattern 304. In some embodiments, the aiming cross pattern 304 may be presented in the same color as a whole. In some embodiments, the aiming cross pattern 304 may also include different colors. The aiming cross pattern 304 includes the central aiming point AP. In the present application, the central aiming point AP has a variable size, which will be discussed in detail in the following paragraphs. Figure 2C shows the aiming cross pattern 306. In some embodiments, the aiming cross pattern 306 may be presented in the same color as a whole. In some embodiments, the aiming cross pattern 306 may also include different colors. The aiming cross pattern 306 includes the central aiming point AP. In the present application, the central aiming point AP has a variable size, which will be discussed in detail in the following paragraphs.

[0028] Figure 3A , 3B and FIG. 3C illustrate a schematic diagram of the central aiming point AP of the crosshair pattern according to some embodiments of the present disclosure. Figure 3A The central aiming point AP-1 is drawn. The central aiming point AP-1 is a pattern projected by the display device 122 onto the transmissive screen 120. The central aiming point AP-1 can be Figure 2A , 2B , the aiming point near the geometric center of the crosshair patterns 302, 304, or 306 drawn in FIG. 2C. The central aiming point AP-1 includes a first pattern 310 and a second pattern 312. The first pattern 310 has a geometric center G. The first pattern 310 can be a solid circle and has a radius R1. In other embodiments, the first pattern 310 can be a solid geometric shape, such as a triangle, rectangle, rhombus, V shape, or inverted V shape.

[0029] The second pattern 312 extends radially outward from the geometric center G and surrounds the first pattern 310. The second pattern 312 has an inner edge 312E1 close to the first pattern 310 and an outer edge 312E2 far from the first pattern 310. The inner edge 312E1 of the second pattern 312 maintains a fixed distance R2 from the geometric center G, and the outer edge 312E2 of the second pattern 312 maintains a fixed distance R3 from the geometric center G. The inner edge 312E1 of the second pattern 312 is equidistant from the first pattern 310 by (R2 - R1). In other embodiments, after adjustment, the inner edge 312E1 of the second pattern 312 may not be equidistant from the first pattern 310. The second pattern 312 has a notch 312n with a width of W1. The cause of the notch 312n will be described in the following paragraphs with reference to Figure 5A for illustration.

[0030] Refer to Figure 3A, there is an annular gap T1 between the first pattern 310 and the second pattern 312. The width of the annular gap T1 is the difference between R2 and R1. In some embodiments, the radius R1 of the first pattern 310 may be in the range of 10 micrometers (μm) to 14 micrometers. In some embodiments, the difference between R2 and R1 (i.e., the width of the annular gap T1) may be in the range of 2 micrometers to 8 micrometers. It should be noted that the width of the annular gap T1 needs to be controlled within a certain range. In this way, when the first pattern 310 and the second pattern 312 are lit simultaneously, the user's naked eye can ignore the non-luminous annular gap T1. Therefore, the central aiming point AP-1 observed by the user on the transmissive screen 120 will be very similar to a solid circle with a radius of R3. Specifically, the user can control the appearance of the central aiming point AP-1 via the button 126a or 126b. When the user controls the first pattern 310 to light up alone, the central aiming point AP-1 observed by the user on the transmissive screen 120 is a circle with a radius R1. When the user controls the first pattern 310 and the second pattern 312 to light up simultaneously, the central aiming point AP-1 observed by the user on the transmissive screen 120 is similar to a circle with a radius R3. Through the above design, the user can change the size of the central aiming point of the optical aiming device 100 via the button 126a or 126b according to different application scenarios, without having to purchase target aiming devices with various different sizes of aiming points, improving the convenience of use and reducing unnecessary financial expenditures.

[0031] Figure 3B The central aiming point AP-2 is drawn. The central aiming point AP-2 is a pattern projected by the display device 122 on the transmissive screen 120. The central aiming point AP-2 can be Figure 2A , 2B , the aiming point near the geometric center of the aiming cross patterns 302, 304, or 306 drawn in 2C. As Figure 3B shown, the central aiming point AP-2 includes the first pattern 310, the second pattern 312, and the third pattern 314. The first pattern 310 has a geometric center G. The first pattern 310 can be a solid circle and has a radius R1. The second pattern 312 extends radially outward from the geometric center G and surrounds the first pattern 310. The third pattern 314 extends radially outward from the geometric center G and surrounds the second pattern 312.

[0032] The second pattern 312 has an inner edge 312E1 close to the first pattern 310 and an outer edge 312E2 far from the first pattern 310. The inner edge 312E1 of the second pattern 312 maintains a fixed distance R2 from the geometric center G, and the outer edge 312E2 of the second pattern 312 maintains a fixed distance R3 from the geometric center G. The second pattern 312 has a notch 312n with a width of W2.

[0033] The third pattern 314 has an inner edge 314E1 close to the second pattern 312 and an outer edge 314E2 far from the second pattern 312. The inner edge 314E1 of the third pattern 314 maintains a fixed distance R4 from the geometric center G, and the outer edge 314E2 of the third pattern 314 maintains a fixed distance R5 from the geometric center G. The third pattern 314 has a notch 314n with a width of W2. The inner edge 314E1 of the third pattern 314 maintains an equal spacing (R4 - R3) from the second pattern 312.

[0034] Refer to Figure 3B , there is an annular gap T1 between the first pattern 310 and the second pattern 312. There is an annular gap T2 between the second pattern 312 and the third pattern 314. The characteristics of the annular gap T1 are consistent with Figure 3A the annular gap T1 therein and will not be elaborated here.

[0035] The width of the annular gap T2 is the difference between R4 and R3. In some embodiments, R3 can be in the range of 22 microns to 28 microns. In some embodiments, the difference between R4 and R3 (i.e., the width of the annular gap T2) can be in the range of 2 microns to 8 microns. It should be noted that the width of the annular gap T2 needs to be controlled within a certain range, so that when the first pattern 310, the second pattern 312, and the third pattern 314 are lit simultaneously, the central aiming point AP-2 observed by the user on the transmissive screen 120 will be close to a solid circle with a radius of R5. Specifically, the user can control the shape of the central aiming point AP-2 via the button 126a or 126b. When the user controls only the first pattern 310 to be lit, the central aiming point AP-2 observed by the user on the transmissive screen 120 is a circle with a radius R1. When the user controls the first pattern 310 and the second pattern 312 to be lit simultaneously, the central aiming point AP-2 observed by the user on the transmissive screen 120 is similar to a circle with a radius R3. When the user controls the first pattern 310, the second pattern 312, and the third pattern 314 to be lit simultaneously, the central aiming point AP-2 observed by the user on the transmissive screen 120 is similar to a circle with a radius R5.

[0036] Figure 3C The central aiming point AP-3 is drawn. The central aiming point AP-3 is a pattern projected by the display device 122 on the transmissive screen 120. The central aiming point AP-3 can be Figure 2A , 2B , the aiming point close to the geometric center of the aiming cross patterns 302, 304, or 306 drawn by 2C. As Figure 3CAs shown, the central aiming point AP-3 includes a first pattern 310, a second pattern 312, and a third pattern 314'. Figure 3C The central aiming point AP-3 of Figure 3B has a similar structure to the central aiming point AP-2 of Figure 3B , with the only difference being that the width W3 of the notch 314n' of the third pattern 314' is different from the width W2 of the notch 312n of the second pattern 312. In some embodiments, the width W3 of the notch 314n' is less than the width W2 of the notch 312n. Due to the smaller width W3 of the notch 314n', when the first pattern 310, the second pattern 312, and the third pattern 314' are lit simultaneously, the non-luminous notch 314n' will be less obvious, and the user can observe a central aiming point AP-3 with a radius R5 on the transmissive screen 120.

In some cases, the second conductive layer 208 is patterned to cover only the effective light-emitting region of the display device 122. In some cases, the second conductive layer 208 is in contact with the organic carrier transport layer 206L4.

[0051] The second conductive layer 208 may have a thickness of about to about In some embodiments, the second conductive layer 208 may have a thickness of about to about In some embodiments, the second conductive layer 208 may have a thickness of about 150 to about In some embodiments, the second conductive layer 208 may have a thickness of about to about In some embodiments, the second conductive layer 208 may have a thickness of about to about In some embodiments, the second conductive layer 208 may have a thickness of about to about In some embodiments, the second conductive layer 208 may have a thickness of about

[0052] In this case, the second conductive layer 208 can be a cathode. The second conductive layer 208 can be a metal material, such as Ag, Mg, etc. In some embodiments, the second conductive layer 208 includes ITO (indium tin oxide) or IZO (indium zinc oxide).

[0053] Referring to Figure 4 , the first conductive layer 204 may have a first sidewall 204a and a second sidewall 204b. The light blocking layer 201 may have a first sidewall 201a and a second sidewall 201b. The first sidewall 204a of the first conductive layer 204 is not aligned with the first sidewall 201a of the light blocking layer 201. In certain embodiments, there is a displacement d1 between the first sidewall 204a of the first conductive layer 204 and the first sidewall 201a of the light blocking layer 201.

[0054] The second sidewall 204b of the first conductive layer 204 is not aligned with the second sidewall 201b of the light blocking layer 201. In certain embodiments, there is a displacement d2 between the second sidewall 204b of the first conductive layer 204 and the second sidewall 201b of the light blocking layer 201. In certain embodiments, the displacement d1 and the displacement d2 can be substantially equal. In certain embodiments, the displacement d1 and the displacement d2 can have slight differences due to the manufacturing process.

[0055] The displacements d1 and d2 between the light blocking layer 201 and the first conductive layer 204 can enable the light blocking layer 201 to effectively block the stray light emitted near the first sidewall 201a and the second sidewall 204b, improving the clarity of the displayed pattern of the display device 122.

[0056] As Figure 4As shown, the first conductive layer 204 is separated into several segments by the opening 204n, and a single segment can have a length L1. The spacing length between two adjacent bumps 205 is L2 (i.e., the width of the exposed surface 204s1 of the first conductive layer 204). The light-blocking layer 201 is separated into several segments by the opening 201n, and the opening 201n can have a length L3. The relationship among the length L1, the length L2, and the length L3 is L1 > L2 > L3. The spacing length L2 between two adjacent bumps 205 can correspond to the effective light-emitting area of the display device 122. Specifically, between the first conductive layer 204 and the second conductive layer 208, the carrier injection layer 206L1, the carrier transport layer 206L2, the organic emission layer 206L3, and the organic carrier transport layer 206L4 provided within the range of the length L2 can emit light due to the transfer of carriers.

[0057] The length L3 of the opening 201n is less than the effective light-emitting area (i.e., the length L2), enabling the light-blocking layer 201 to control the light-emitting pattern of the display device 122. Specifically, in Figure 4 the drawn cross-sectional view, the display device 122 has an effective light-emitting area of length L2, but only the light energy passing through the opening 201n (i.e., the length L3) of the light-blocking layer 201 can be viewed by the user. The light-emitting pattern projected by the display device 122 onto the transmissive screen 120 corresponds to the pattern formed by the openings 201n. The relationship between the light-blocking layer 201 and the first conductive layer 204 will be described later Figure 5B in accordance with the top view angle SA.

[0058] Figure 5A A schematic diagram of the first conductive layer is shown in accordance with certain embodiments of the present disclosure. Figure 5A A top view of the first conductive layer 204 is shown. The first conductive layer 204 includes a first portion 204p1 and a second portion 204p2. There is an annular gap T1 between the first portion 204p1 and the second portion 204p2. The annular gap T1 can correspond to Figure 4 the opening 204n shown in

[0059] Although Figure 5AAlthough not drawn in [the figure], a carrier injection layer 206L1, a carrier transport layer 206L2, an organic emission layer 206L3, an organic carrier transport layer 206L4, and a second conductive layer 208 may be provided on a first part 204p1 and a second part 204p2 of the first conductive layer 204. Therefore, the first part 204p1 and the second part 204p2 can emit light and project a pattern corresponding to the outer shapes of the first part 204p1 and the second part 204p2 onto a transmissive screen 120. In contrast, a third part 204e1 and a fourth part 204e2 do not emit light and are only used for conduction. The first part 204p1 and the second part 204p2 of the first conductive layer 204 that emit light can project, onto the transmissive screen 120, a first pattern 310 and a second pattern 312 corresponding to Figure 3A as shown. Therefore, the first conductive layer 204 has a first part 204p1 corresponding to the first pattern 310 and a second part 204p2 corresponding to the second pattern 312.

[0060] Referring also to Figure 3A and Figure 5A , a third part 204e1 of the first conductive layer 204 itself does not emit light but can conduct electricity to the first part 204p1 to make it emit light. The second part 204p2 has a notch to facilitate the third part 204e1 to pass through and connect to the first part 204p1. Therefore, Figure 5A after the second part 204p2 in Figure 3A is projected onto the transmissive screen 120, a notch 312n corresponding to the second pattern 312 in

[0061] Figure 5B is produced. FIG. [X] shows a schematic diagram of the relationship between the first conductive layer and the light shielding layer from a top view according to some embodiments of the present disclosure. Figure 5B The first conductive layer and the light shielding layer shown in Figure 4 are drawn according to a top view angle SA in Figure 5B . For ease of illustration, Figure 5B only shows the first part 204p1 and the second part 204p2 of the first conductive layer, and the third part 204e1 and the fourth part 204e2 are omitted. As Figure 5B shows, the light shielding layer 201 has an opening 201n, and the shape of the opening 201n generally corresponds to the first part 204p1 and the second part 204p2 of the first conductive layer. However, it should be noted that a first sidewall 204a of the first conductive layer 204 is not aligned with a first sidewall 201a of the light shielding layer 201, and a second sidewall 204b of the first conductive layer 204 is not aligned with a second sidewall 201b of the light shielding layer 201. In addition, when observed from the top view angle SA, the light shielding layer 201 covers an annular gap T1 between the first part 204p1 and the second part 204p2 of the first conductive layer.

[0062] In addition, when observed from the top-down perspective SA, the light-blocking layer 201 partially overlaps with the first portion 204p1 of the first conductive layer 204, and the light-blocking layer 201 also partially overlaps with the second portion 204p2 of the first conductive layer 204. As discussed above, the displacement between the light-blocking layer 201 and the first conductive layer 204 can enable the light-blocking layer 201 to effectively block the stray light emitted near the first sidewall 201a and the second sidewall 204b, thereby improving the clarity of the displayed pattern of the display device 122.

[0063] Figure 6A Illustrates a schematic diagram of a first conductive layer according to some embodiments of the present disclosure. Figure 6A The drawn first conductive layer is the same as the Figure 5A drawn first conductive layer. The cross-sections along the line segments OA and OB will be described in the subsequent paragraphs with reference to Figures 6B to 6D for illustration.

[0064] Although the present disclosure does not specifically illustrate the first conductive layer 204 corresponding to Figure 3B or 3C, those of ordinary skill in the art should understand that the first conductive layer 204 corresponding to Figure 3B or 3C will have three portions, respectively corresponding to the first pattern 310, the second pattern 312, and the third pattern 314. The portions of the first conductive layer 204 corresponding to the second pattern 312 and the third pattern 314 will each have a notch.

[0065] Figure 6B Illustrates a schematic cross-sectional structure of a display device along the Figure 6A line segment OA shown in Figure 6B Illustrates along the Figure 6A line segment OA shown in the cross-sectional structure 122c1. The light-blocking layer 201, the cover layer 202, the first conductive layer 204, the bump 205, the carrier injection layer 206L1, the carrier transport layer 206L2, the organic emission layer 206L3, the organic carrier transport layer 206L4, and the second conductive layer 208 are sequentially disposed on the substrate 200. The opening 204n between the first portion 204p1 and 204p2 of the first conductive layer 204 corresponds to the Figure 6A annular gap T1 shown in

[0066] Figure 6C Illustrates a schematic cross-sectional structure of a display device along the Figure 6A line segment OB shown in Figure 6C Illustrates along the Figure 6A line segment OB shown in the cross-sectional structure 122c2.

[0067] A light-blocking layer 201, a covering layer 202, a first conductive layer 204, bumps 205, a carrier injection layer 206L1, a carrier transport layer 206L2, an organic emission layer 206L3, an organic carrier transport layer 206L4, and a second conductive layer 208 are sequentially disposed on a substrate 200. The first conductive layer 204 includes a first portion 204p1 and a third portion 204e1. As Figure 6C shown, a carrier injection layer 206L1, a carrier transport layer 206L2, an organic emission layer 206L3, an organic carrier transport layer 206L4, and a second conductive layer 208 are disposed above the first portion 204p1 of the first conductive layer 204. Therefore, the first portion 204p1 of the first conductive layer 204 corresponds to a light-emitting portion. The bumps 205 covering the third portion 204e1 of the first conductive layer 204 isolate the first conductive layer 204 from the carrier injection layer 206L1, the carrier transport layer 206L2, the organic emission layer 206L3, the organic carrier transport layer 206L4, and the second conductive layer 208 above it. Therefore, the third portion 204e1 of the first conductive layer 204 corresponds to a non-light-emitting portion. The third portion 204e1 of the first conductive layer 204 is only used for conduction. In some embodiments, the light-blocking layer 201 also blocks the third portion 204e1 of the first conductive layer 204, so that the stray light emitted at the junction with the first portion 204p1 is not observable by the user, improving the clarity of the displayed pattern of the display device 122.

[0068] Figure 6D Illustrates a cross-sectional structure schematic diagram of a display device along the Figure 6A line segment OB shown in. Figure 6D Illustrates along the Figure 6A cross-sectional structure 122c3 of the line segment OB shown in. Figure 6D The illustrated cross-sectional structure 122c3 is similar to the Figure 6C illustrated cross-sectional structure 122c2, except that the carrier injection layer 206L1, the carrier transport layer 206L2, the organic emission layer 206L3, and the organic carrier transport layer 206L4 are only disposed above the first portion 204p1 of the first conductive layer 204, but do not cover the third portion 204e1 of the first conductive layer 204 as Figure 6C shown. The first portion 204p1 of the first conductive layer 204 corresponds to a light-emitting portion, while the third portion 204e1 of the first conductive layer 204 corresponds to a non-light-emitting portion.
