Please continue to refer to FIGS. 1 and 3. In this embodiment, the first light guide 30a includes a first light-transmitting portion 32, a second light-transmitting portion 34, and a third light-transmitting portion 36 that are sequentially stacked. The refractive index of the portion 34 is different from that of the first light-transmitting portion 32 and the third light-transmitting portion 36, so that the light entering the first light guide 30a propagates from the first light-transmitting portion 34 to the second light-transmitting The portion 34 is refracted, and is refracted when propagating from the second light-transmitting portion 34 to the third light-transmitting portion 36. Specifically, the first light-transmitting portion 32 and the third light-transmitting portion 36 may be made of the same material, and the materials of the second light-transmitting portion 34 and the first light-transmitting portion 32 and the third light-transmitting portion 36 are different. In one embodiment, the first light-transmitting portion 32, the second light-transmitting portion 34, and the third light-transmitting portion 36 are integrally formed, and the first light guide 30a is detachably attached to the display surface 40 of the first display panel 20a In other words, the first light-transmitting portion 32, the second light-transmitting portion 34, and the third light-transmitting portion 36 are different parts of the first light guide 30a. In another embodiment, the first light-transmitting portion 32, the third The second light-transmitting portion 34 and the third light-transmitting portion 36 are independent transparent prisms. The first light-transmitting portion 32, the second light-transmitting portion 34, and the third light-transmitting portion 36 are fixed to each other by pasting, splicing, etc. to form the first One light guide 30a.

Please refer to FIG. 3. In this embodiment, the refractive indexes of the first light-transmitting portion 32 and the third light-transmitting portion 36 are the same, and are different from those of the second light-transmitting portion 34, so that the light emitted from the display area 44 is at The propagation direction when entering the first light-transmitting portion 32 and the third light-transmitting portion 36 are parallel, in other words, the first light guide 30a translates the light emitted from the display area 44 in a direction parallel to the display surface 40 and covers the first Non-display area 42. Specifically, the light emitted from the display area 44 sequentially passes through the first light-transmitting portion 32, the second light-transmitting portion 34, and the third light-transmitting portion 36, and the emitted light is horizontal to the light emitted from the display area 44 Pan and cover the first non-display area 42. Specifically, the light emitted from the display area 44 undergoes first refraction when entering the second light transmitting portion 34 from the first light transmitting portion 32, and undergoes second refraction when entering the third light transmitting portion 36 from the second light transmitting portion 34. , The light deflects in the propagation direction during the first refraction and the second refraction. Further, the refractive indexes of the first light-transmitting portion 32 and the third light-transmitting portion 36 are the same and are the same as those of the second light-transmitting portion 34 The refractive index of is different, the deflection direction of the light in the first refraction is opposite to that of the second refraction, the amount of deflection is the same, so that the light emitted after passing through the first light guide 30a relative to the light emitted by the display area 44 A horizontal translation. Further, the image displayed on the display area 44 of the display surface 40 is transmitted through the first light guide 30a and then shifts in a horizontal direction as a whole. The light emitted through the first light guide 30a can be emitted from directly above the first non-display area 42 after being translated, so as to cover the first non-display area 42. The image displayed by the display device may cover the first non-display area 42, thereby blocking the encapsulation area 22 corresponding to the first non-display area 42 inside the first display panel 20a, the user will not see the first non-display area 42, the display device obtains The display area without a border on one side improves the display effect.

It is understandable that the refractive indexes of the first light-transmitting portion 32 and the third light-transmitting portion 36 are the same in theory. In fact, due to the presence of impurities and other external factors in the material, the two materials must be It is unlikely that the refractive indexes are exactly the same, so it suffices that the difference between the refractive index n1 of the first light transmitting portion 32 and the refractive index n3 of the third light transmitting portion 36 is less than a preset threshold. In other embodiments, since it is necessary to ensure that the emitted light is perpendicular to the light exit surface 360, the refractive index sizes of the first light-transmitting portion 32, the second light-transmitting portion 34, and the third light-transmitting portion 36 can be fine-tuned accordingly.

1 and 3, in this embodiment, a first refractive surface 324 is formed between the first light-transmitting portion 32 and the second light-transmitting portion 34, and between the second light-transmitting portion 34 and the third light-transmitting portion 36 A second refractive surface 346 is formed. The first refractive surface 324 and the second refractive surface 346 are parallel and form an angle with the display surface 40. Specifically, the first refractive surface 324 is the interface between the first light-transmitting portion 32 and the second light-transmitting portion 34, one side of the first refractive surface 324 is the first light-transmitting portion 32, and the other side is the second light-transmitting portion In the portion 34, the light passes through the first refractive surface 324 so that the first light-transmitting portion 32 enters the second light-transmitting portion 34; the second refractive surface 346 is the interface between the second light-transmitting portion 34 and the third light-transmitting portion 36, One side of the second refractive surface 346 is the second light transmitting portion 34, and the other side is the third light transmitting portion 36. The light passes through the second refractive surface 346 so that the second light transmitting portion 34 enters the third light transmitting portion 36 .

The refractive index of the first light transmitting portion 32 may be greater than the refractive index of the second light transmitting portion 34, and the refractive index of the first light transmitting portion 32 may also be smaller than the refractive index of the second light transmitting portion 34.

Taking FIG. 3 as an example, in one embodiment, the first refractive surface 324 and the second refractive surface 346 are inclined as shown, and the refractive index of the first light transmitting portion 32 of the first light guide 30a is greater than that of the second light transmitting The refractive index of the portion 34 gradually increases from the first refractive surface 324 to the display surface 40 along the direction in which the display area 44 points to the first non-display area 42. The light emitted from the display area 44 of the first display panel 20a enters the first light-transmitting portion 32 perpendicularly to the light incident surface 320 of the first light-transmitting portion 32 of the first light guide 30a. There is an angle between them, so the first refraction can occur, and the light after the first refraction is deflected counterclockwise, and the angle between the light after the first refraction and the second refractive surface 346, so the second time can occur Refraction, the light beam after the second refraction is deflected clockwise, and is emitted from the light exit surface 360 of the third light transmitting portion 36. The light exiting the light guide 30 from the light exit surface 360 of the third light transmitting portion 36 and the light entering the light guide 30 from the light entrance surface 320 of the first light transmitting portion 32 are parallel to each other, and only translation occurs, specifically along the display area 44 translates in the direction of the first non-display area 42.

3, the light emitted from the display area 44 enters the first light-transmitting portion 32 perpendicularly to the light-incident surface 320 of the first light-transmitting portion 32, and there is an angle between the light and the first refractive surface 324, so it can occur The first refraction, the angle between the light after the first refraction and the second refraction surface 346, so the second refraction can occur, the light after the second refraction from the light exit surface 360 of the third light-transmitting portion 36 Shoot out. The light exiting the first light guide 30a from the light exit surface 360 of the third light transmitting portion 36 and the light entering the first light guide 30a from the light entrance surface 320 of the first light transmitting portion 32 are parallel to each other, and only occur in the horizontal direction Translation, further, each light emitted from the display area 44 perpendicular to the light incident surface 320 of the first light-transmitting portion 32 passes through the first light guide 30a and undergoes the same amount of translation. Correspondingly, the display area 44 After the displayed image passes through the first light guide 30a, the entire image only shifts in the horizontal direction, and the content, scale, and quality of the image do not change.

Please refer to FIGS. 1 and 3. In this embodiment, the light incident surface 320 of the first light transmitting portion 32 is parallel to the first display panel 20 a, and the light exit surface 360 of the third light transmitting portion 36 is parallel to the first display panel 20 a. Specifically, the light incident surface 320 of the first light transmitting portion 32 is parallel to the display surface 40 of the first display panel 20a, and the light exit surface 360 of the third light transmitting portion 36 is parallel to the display surface 40 of the first display panel 20a, so that The light emitted from the display surface 40 of the first display panel 20a may enter the first light-transmitting portion 32 perpendicular to the direction of the light-incident surface 320 of the first light-transmitting portion 32, correspondingly, from the light-emitting surface 360 of the third light-transmitting portion 36 The emitted light rays are all perpendicular to the light exit surface 360 of the third light-transmitting portion 36, and a better display effect is obtained. In one embodiment, the light incident surface 320 of the first light-transmitting portion 32 is attached to the display surface 40 of the first display panel 20a, so that the light emitted by the first display panel 20a is perpendicular to the first light-transmitting portion as much as possible 32 enters the first light-transmitting portion 32, correspondingly, as much light as possible exits the third light-transmitting portion 36 perpendicular to the third light-transmitting portion 36, thereby improving the brightness of the image displayed by the display device.

Please continue to refer to FIG. 3. In this embodiment, by adjusting the value of the amount of translation d when the light emitted from the first display panel 20a enters the first light-transmitting portion 32 and exits from the third light-transmitting portion 36, the display surface can be adjusted The image displayed at 40 exactly covers the first non-display area 42 after translation, and the edge of the image displayed by the display surface 40 after the translation is aligned with the edge of the first display panel 20a, so that the image displayed by the display device is complete. Specifically, the value of the translation amount d is equal to the lateral length of the first non-display area 42, that is, the length of the first non-display area 42 in the connecting direction of the first non-display area 42 and the display area 44. The first non-display area 42 can be completely blocked, and there will be no situation where too much light is shifted and part of the image cannot be displayed. Further, the amount of translation d when the light emitted by the first display panel 20a enters the first light-transmitting portion 32 and when it exits from the third light-transmitting portion 36 is related to the characteristics of the plurality of first light guides 30a, including the first light-transmitting portion 30a. The ratio of the refractive index of the material of the light portion 32 and the second light transmitting portion 34 is n ₁₂ =n ₁ /n ₂ =n ₃ /n ₂ , where n ₁ is the refractive index of the first light transmitting portion 32 and n ₂ is the second The refractive index of the light transmitting portion 34, n ₃ is the refractive index of the second light transmitting portion 34, n ₁ = n ₃ . The angle a between the first refractive surface 324 or the second refractive surface 346 and the display surface 40, and the distance L in the vertical direction between the first refractive surface 324 and the second refractive surface 346 (hereinafter simply referred to as the vertical distance L). Specifically, the relationship between the translation amount d and the ratio n ₁₂ , the included angle a, and the vertical distance L is as follows:

d=L*sin(a)/cos(arcsin(n ₁₂ *sina))

The translation amount d is positively correlated with the ratio n ₁₂ , the translation amount d is negatively correlated with the included angle a, and the translation amount d is positively correlated with the vertical distance L. Therefore, by controlling the material refractive indexes of the first light-transmitting portion 32, the second light-transmitting portion 34, and the third light-transmitting portion 36, and the angle a between the first refractive surface 324 or the second refractive surface 346 and the display surface 40, The vertical distance L between the first refractive surface 324 and the second refractive surface 346 can obtain different amounts of translation d, so that the use of different first light guides 30a can be applied to the first display panel 20a with different sizes of the first non-display area 42 .
