Description

Technical Field

[0001] The present invention relates to a display device, and particularly to a stereoscopic display device. Background Art

[0002] In recent years, with the progress of display technologies, users have higher and higher requirements for display quality (such as image resolution, color saturation, etc.). In addition to high image resolution and high color saturation, in some applications, users also hope that the display can display stereoscopic images.

[0003] Current stereoscopic image display technologies can be generally classified into stereoscopic display devices that require users to wear special glasses for viewing and naked eyes type (or namely auto-stereoscopic) stereoscopic display devices that can be directly viewed without glasses. Conventional naked eyes type stereoscopic display devices have the problem of making users dizzy when viewing the screen. Therefore, some other types of naked eyes type stereoscopic display devices have been proposed, such as multi-layer displays. The multi-layer display includes a first display panel disposed at the rear and a transparent second display panel disposed in front, and there is an actual distance between the first display panel and the transparent second display panel. Since the multi-layer display has a true depth property, it will not encounter the problem of making users dizzy when viewing the screen. However, the second display panel of the multi-layer display is disposed in front of the first display panel, and the second display panel is prone to the problem of insufficient strength. Summary of the Invention

[0004] The present invention provides a stereoscopic display device with sufficient strength.

[0005] The stereoscopic display device of the present invention includes a first display element, a second display element, a first light-shielding element, and a photosensitive element. The second display element is separated from the first display element by a distance. The second display element has a first area and a second area. The first area of the second display element overlaps the first display element. The second area of the second display element is located outside the area of the first display element. The first light-shielding element is located between the first display element and the second display element and is adjacent to the second display element. The first light-shielding element has a first light-shielding portion. The entity of the first light-shielding portion overlaps the second area of the second display element. The main opening of the first light-shielding portion is located on the first display element. The photosensitive element is located outside the area of the first display element and is offset from the entity of the first light-shielding portion of the first light-shielding element.

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

[0060] It should be understood that when an element such as a layer, film, region, or substrate is referred to as being "on" or "connected to" another element, it can be directly on or connected to the other element, or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" or "directly connected to" another element, no intervening elements are present. As used herein, "connected" can refer to physical and / or electrical connection. Furthermore, "electrically connected" or "coupled" can mean that there are other elements between two elements.

[0061] As used herein, "about", "approximate", or "substantially" includes the stated value and an average within an acceptable deviation range of a particular value determined by a person of ordinary skill in the art, taking into account the particular amount of the measurement and the error associated with the measurement (i.e., the limitations of the measurement system). For example, "about" can mean within one or more standard deviations of the stated value, or within ±30%, ±20%, ±10%, ±5%. Furthermore, "about", "approximate", or "substantially" as used herein can be selected according to optical properties, etching properties, or other properties to choose a more acceptable deviation range or standard deviation, rather than applying one standard deviation to all properties.

[0062] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by a person of ordinary skill in the art to which this invention belongs. It will be further understood that terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and this invention, and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

[0064] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the stereoscopic display device 10 includes a first display element 110 and a second display element 120. The first display element 110 and the second display element 120 are spaced apart by a distance D in a direction d parallel to the user's line of sight. The second display element 120 is a transparent display. In some embodiments, the transmittance of the second display element 120 may be greater than or equal to 50%. The first image displayed by the first display element 110 can pass through the second display element 120 and be received by the user's eyes. That is, the user's eyes can simultaneously receive the first image displayed by the first display element 110 and the second image displayed by the second display element 120. Since the first display element 110 and the second display element 120 are spaced apart by a real distance D in the direction d parallel to the user's line of sight, the combination of the first image displayed by the first display element 110 and the second image displayed by the second display element 120 can provide a real depth-of-field image. After the real depth-of-field image is received by the human eye, the brain can perceive a stereoscopic image. In some embodiments, the resolution of the second display element 120, for example, falls within the range of 60 ppi to 200 ppi, the distance D, for example, falls within the range of 4.5 mm to 7.5 mm, and the resolution of the first display element 110, for example, falls within the range of 100 ppi to 300 ppi. In some embodiments, preferably, the resolution of the second display element 120 is 85 ppi, the distance D is about 6 mm, and the resolution of the first display element 110 is 167 ppi or 210 ppi, but the present invention is not limited thereto.

[0065] In some embodiments, the second display element 120 is, for example, a transparent light-emitting diode display panel, where the transparent light-emitting diode display panel may include a driving backplane having a plurality of through regions and pixel regions, a plurality of light-emitting diodes disposed in the pixel regions and electrically connected to the driving backplane, and a molding layer covering the plurality of light-emitting diodes. However, the present invention is not limited thereto. In other embodiments, the second display element 120 may also be other types of transparent displays.

[0066] In some embodiments, the first display element 110 may include, for example, a liquid crystal display panel 112 and a backlight module 114 disposed behind the liquid crystal display panel 112. In some embodiments, the backlight module 114 may selectively have a local dimming function. In some embodiments, the backlight module 114 may include a circuit board 114b, a plurality of light-emitting elements 114a electrically connected to the circuit board 114b, at least one optical film 114c disposed above the plurality of light-emitting elements 114a, and a back frame 114d for accommodating the circuit board 114b, the light-emitting elements 114a, and at least one optical film 114c. However, the present invention is not limited thereto. In other embodiments, the first display element 110 may also be other types of displays.

[0067] In some embodiments, to cooperate with the application of the stereoscopic display device 10 (for example, used as an electronic instrument panel in front of the driver's seat), the first display element 110 and / or may be selectively bent to have a radius of curvature. For example, in some embodiments, the radius of curvature of the second display element 120 is, for example, 3000 mm, and the first display element 110 may be non-bent and planar. In other embodiments, both the first display element 110 and the second display element 120 may be bent and have a radius of curvature.

[0068] The stereoscopic display device 10 further includes a first concealer element 130 located between the first display element 110 and the second display element 120. The first concealer element 130 is adjacent to the second display element 120. The first concealer element 130 is closer to the second display element 120 and farther from the first display element 110. The second display element 120 has a first area 120a and a second area 120b. The first area 120a of the second display element 120 overlaps the first display element 110. The second area 120b of the second display element 120 is outside the area of the first display element 110. The first concealer element 130 has a first light-shielding portion 134. The solid body 134a of the first light-shielding portion 134 overlaps the second area 120b of the second display element 120. The main opening 134b of the first light-shielding portion 134 is located on the first display element 110. The first concealer element 130 can increase the strength of the second display element 120 and provide concealer and support functions.

[0069] For example, in some embodiments, the first light-shielding element 130 may include a first transparent substrate 132, and a first light-blocking portion 134 is disposed on the first transparent substrate 132. In some embodiments, the first light-blocking portion 134 may be selectively disposed on the surface 132a of the first transparent substrate 132 facing the first display element 110. However, the present invention is not limited thereto. In other embodiments, the first light-blocking portion 134 may also be selectively disposed on the surface 132b of the first transparent substrate 132 facing away from the first display element 110. In some embodiments, the first light-blocking portion 134 is, for example, an ink pattern layer, but the present invention is not limited thereto.

[0070] The stereoscopic display device 10 further includes a photosensitive element S, which is located outside the area of the first display element 110 and is offset from the entity 134a of the first light-blocking portion 134 of the first light-shielding element 130. For example, in some embodiments, the first light-shielding element 130 may be selectively located between the photosensitive element S and the second display element 120. That is, in some embodiments, the photosensitive element S may be selectively disposed behind the first light-shielding element 130. In some embodiments, the first light-blocking portion 134 of the first light-shielding element 130 further has an auxiliary opening 134c, and the first transparent substrate 132 of the first light-shielding element 130 has a through hole 132c. The auxiliary opening 134c and the through hole 132c substantially coincide, and the auxiliary opening 134c and the through hole 132c are located above the photosensitive element S. The sensing light from the outside can be transmitted to the photosensitive element S more favorably through the auxiliary opening 134c and the through hole 132c, thereby obtaining an image with better quality. In some embodiments, the photosensitive element S is, for example, an image extraction element that can sense images in the visible light band and / or the infrared light band, but the present invention is not limited thereto.

[0071] In some embodiments, the stereoscopic display device 10 further includes a carrier structure 150. The carrier structure 150 is used to carry the first display element 110 and the second display element 120 and maintain a distance D between the first display element 110 and the second display element 120.

[0072] Specifically, in some embodiments, the carrier structure 150 includes a first sidewall 151 and a stage 152. The first sidewall 151 defines a first accommodation space R1, and at least a part of the first display element 110 is disposed in the first accommodation space R1. The stage 152 is connected to one end of the first sidewall 151 away from the first display element 110 and extends outward from the first accommodation space R1. The first light-shielding element 130 is mounted on the stage 152, and the first light-shielding portion 134 of the first light-shielding element 130 shields the stage 152 and the first sidewall 151. In some embodiments, the carrier structure 150 may further optionally include a groove 153, where the first sidewall 151 is located between at least a part of the first display element 110 and the groove 153, and the photosensitive element S may be optionally disposed in the groove 153, but the present invention is not limited thereto.

[0073] In some embodiments, the three-dimensional display device 10 further includes an adhesive element 140, which is disposed on the stage 152 of the carrier structure 150 and connects the first light-shielding element 130 and the stage 152 of the carrier structure 150. In some embodiments, the adhesive element 140 may have a first through hole 142 and a second through hole 144, which are respectively located above the first display element 110 and the photosensitive element S. In some embodiments, the adhesive element 140 may also have a buffering function. For example, in some embodiments, the adhesive element 140 may be a foam tape, but the present invention is not limited thereto. In some embodiments, the adhesive element 140 has a dust-proof function in addition to the adhesive and buffering functions, and can prevent dust from entering the first accommodation space R1 and accumulating on the first display element 110.

[0074] In some embodiments, the carrier structure 150 further includes a second sidewall 154, which is connected to the stage 152. The first sidewall 151 and the second sidewall 154 extend in two opposite directions z and -z and are respectively located on opposite sides of the stage 152. The stage 152 and the second sidewall 154 define a second accommodation space R2. The second display element 120 and the first light-shielding element 130 are disposed in the second accommodation space R2.

[0075] In some embodiments, the stereoscopic display device 10 further includes a second light-shielding element 160, which is mounted on the second sidewall 154 of the carrier structure 150. The second display element 120 is located between the second light-shielding element 160 and the first light-shielding element 130. The second light-shielding element 160 has a second light-shielding portion 164. The entity 164a of the second light-shielding portion 164 shields the second region 120b of the second display element 120 and the second sidewall 154 of the carrier structure 150. The second light-shielding portion 164 has a main opening 164b, which is located above the first display element 110. In some embodiments, the second light-shielding portion 164 of the second light-shielding element 160 further has an auxiliary opening 164c, which is located above the photosensitive element S and the groove 153 of the carrier structure 150. The second light-shielding element 160 can shield the second region 120b (i.e., the non-display region) of the second display element 120, reducing the white fog feeling of the second display element 120. In addition, the second light-shielding element 160 can also increase the strength of the second display element 120. In some embodiments, the second light-shielding element 160 may include a second transparent substrate 162, and the second light-shielding portion 164 is disposed on the second transparent substrate 162. The sensing light from the outside can pass through the auxiliary opening 164c of the second light-shielding portion 164, pass through the second transparent substrate 162, pass through the second display element 120, pass through the through hole 132c and the auxiliary opening 134c of the first light-shielding element 130, and pass through the second through hole 144 of the adhesive element 140 to be transmitted to the photosensitive element S.

[0076] In some embodiments, the stereoscopic display device 10 further includes an anti-reflection and anti-glare film 170, which is disposed on the first display element 110 and is located in the first accommodation space R1 of the carrier structure 150. Disposing the anti-reflection and anti-glare film 170 between the first display element 110 and the second display element 120 can break the interference between the first display element 110 and the second display element 120, thereby improving the problem of Moire. In some embodiments, the haze of the anti-reflection and anti-glare film 170 can fall within the range of 60% to 80%. In some embodiments, preferably, the haze of the anti-reflection and anti-glare film 170 falls within the range of 74% ± 8%, but the present invention is not limited thereto.

[0077] In some embodiments, the stereoscopic display device 10 may further include a load-bearing steel frame 192 (shown in Figure 2 ), a front appearance member 194, and a rear appearance member 196. The load-bearing steel frame 192 is used to lock the carrier structure 150. The front appearance member 194 and the rear appearance member 196 are used to protect the components therein (such as: the second light-shielding element 160, the second display element 120, the first light-shielding element 130, the first display element 110, etc.), and also have an aesthetic effect.

[0078] Please refer to Figure 1, in some embodiments, the stereoscopic display device 10 further includes a processing element 180, electrically connected to the first display element 110, the second display element 120, and the photosensitive element S. In some embodiments, the processing element 180 can determine the display screen of at least one of the first display element 110 and the second display element 120 according to the signal provided by the photosensitive element S.

[0079] Figure 5 It is a schematic flowchart of an operation mode of a stereoscopic display device according to an embodiment of the present invention. Please refer to Figure 1 and Figure 5 , for example, in some embodiments, the photosensitive element S of the stereoscopic display device 10 can be used to detect driving behavior and cause the stereoscopic display device 10 to make corresponding responses. At first, the processing element 180 commands the first display element 110 and / or the second display element 120 to play the startup animation video. Then, as the startup process proceeds, the processing element 180 starts the first-stage detection of the algorithm, using the photosensitive element S to monitor the face (or rather, driving). If a face (or rather, driving) is detected, the processing element 180 commands the first display element 110 and / or the second display element 120 to enter the unlocking screen and then enter the dashboard screen, and the processing element 180 starts the second-stage detection of the algorithm. If no face (or rather, driving) is detected, the startup animation video is continuously played. In the second-stage detection of the algorithm, if abnormal actions of the face (or rather, driving) are detected (such as dangerous driving behaviors like using a mobile phone, turning the head, dozing off, etc.), the processing element 180 commands the first display element 110 and / or the second display element 120 to play a warning screen and may be accompanied by a warning sound effect. In the second-stage detection of the algorithm, if no abnormal actions of the face (or rather, driving) are detected, the processing element 180 commands the first display element 110 and / or the second display element 120 to continue playing the dashboard screen.

[0080] Figure 6 It is a schematic flowchart of another operation mode of a stereoscopic display device according to an embodiment of the present invention. Please refer to Figure 1 and Figure 6 , for example, in some embodiments, the photosensitive element S of the stereoscopic display device 10 can be used to detect the driving angle and cause the stereoscopic display device 10 to make corresponding responses, where the driving angle refers to the angle of the driver's eyes relative to the stereoscopic display device 10. Please refer to Figure 1 and Figure 6 , after entering the dashboard screen, the processing element 180 can start detecting the driving angle. If it is detected that the line connecting the driver's two eyes is not perpendicular to the normal direction N of the first display element 110, the processing element 180 can perform an angle calculation according to a human factor data lookup table to cause the display screens of the second display element 120 in the front and the first display element 110 in the back to make corresponding displacements, thereby optimizing the stereoscopic display effect.

[0081] In some embodiments, the possible positions of the driving eyes can be divided into i regions (for example, if i = 3, the possible positions of the driving eyes are divided into a left region, a middle region, and a right region; if i = 9, the possible positions of the driving eyes are divided into a nine-grid region...), and the optimal positions to which the display screens of the front and rear displays (i.e., the second display screen of the second display element 120 and the first display screen of the first display element 110) need to be moved are recorded in advance for the qth region, where q is a positive integer greater than or equal to 1 and less than or equal to i. If it is detected that the driving eyes appear in the abnormal qth region, the screens of the front and rear displays can be displaced correspondingly according to the previously recorded data to optimize the stereoscopic display effect.

[0082] It should be noted here that the following embodiments follow the component numbers and some content of the foregoing embodiments, where the same numbers are used to represent the same or similar components, and the description of the same technical content is omitted. For the description of the omitted part, reference can be made to the foregoing embodiments, and the following embodiments will not be repeated.

[0083] Figure 7 FIG. is a cross-sectional schematic diagram of a stereoscopic display device according to another embodiment of the present invention. The stereoscopic display device 10A of this embodiment is similar to the foregoing stereoscopic display device 10, and the difference between the two is that the positions of the photosensitive elements S of the two are different. Please refer to Figure 7 , specifically, in this embodiment, the photosensitive element S is not disposed below the second display element 120 and the first light-shielding element 130. The photosensitive element S is located beside the sides of the second display element 120 and the first light-shielding element 130 and below the first light-shielding element 130.

[0084] Figure 8 FIG. is a cross-sectional schematic diagram of a stereoscopic display device according to still another embodiment of the present invention. The stereoscopic display device 10B of this embodiment is similar to the foregoing stereoscopic display device 10, and the difference between the two is that the distance D between the first display element 110 and the second display element 120 is different. Please refer to Figure 1 , the foregoing stereoscopic display device 10 is, for example, applied to the field of vehicle displays, and the distance D (for example: 6 mm) between the first display element 110 and the second display element 120 is relatively large. Please refer to Figure 8 , the stereoscopic display device 10B of this embodiment is, for example, applied to the field of wearable displays (such as a watch), and the distance D (for example: ≤2.5 mm) between the first display element 110 and the second display element 120 is relatively small. Please refer to Figure 8 , in addition, in this embodiment, the stereoscopic display device 10B may further include a transparent element 198 disposed between the anti-reflection and anti-glare film 170 and the first display element 110.

[0085] The second display element 120 and the transparent element 198 have a spacing G. The transparent element 198 has a thickness T. Table 1 below lists the parameters of each component of various embodiments of the stereoscopic display device 10B and the test results of moire and text clarity. As can be seen from Table 1 below, in some embodiments, the resolution of the second display element 120 falls within the range of 60 ppi to 200 ppi, the spacing G falls within the range of 0 mm to 2 mm, the haze of the anti-reflection and anti-glare film 170 falls within the range of 60% to 80%, the thickness T of the transparent element 198 falls within the range of 0 mm to 1.25 mm, the resolution of the first display element 110 falls within the range of 100 ppi to 450 ppi, and the optical performance and visual taste of the stereoscopic display device 10B are good.
