The present invention relates to an image displaying device, and more particularly, to an image displaying device capable of showing curved displaying efficiency via a planar display panel.
A conventional image displaying device includes a planar display and a curved display. The planar display has a small size, but provides worse vision experience due to the displayed planar image. The curved display provides preferred vision experience because of the displayed curved image, but has drawbacks of a huge size and expensive cost. Thus, design of an image displaying device of showing curved displaying efficiency without specific optical membranes and having advantages of the small size and low manufacturing cost is an important issue in the display industry.
The present invention provides curved displaying efficiency for solving above drawbacks.
According to the claimed invention, an image displaying device includes a planar display panel and a light penetrating unit. The planar display panel is adapted to display a plane image. The planar display panel at least includes a first pixel group, a second pixel group and a third pixel group. The second pixel group is located between the first pixel group and the third pixel group. The light penetrating unit is disposed before the planar display panel. When vision passes through the light penetrating unit toward the planar display panel, the vision acquires that a second distance of a second imaging position within the plane image relevant to the second pixel group relative to the planar display panel is greater than a first distance of a first imaging position within the plane image relevant to the first pixel group relative to the planar display panel and a third distance of a third imaging position within the plane image relevant to the third pixel group relative to the planar display panel.
According to the claimed invention, density of the second pixel group is greater than density of the first pixel group and the third pixel group. A focal length of the light penetrating unit relevant to the first pixel group is the same as a focal length of the light penetrating unit relevant to the second pixel group and a focal length of the light penetrating unit relevant to the third pixel group.
According to the claimed invention, the light penetrating unit is an optical lens module having a plurality of lens units. The plurality of lens units at least includes a first lens group, a second lens group and a third lens group respectively aligning with the first pixel group, the second pixel group and the third pixel group. A focal length of the second lens group is different from a focal length of the first lens group and a focal length of the third lens group.
According to the claimed invention, the image displaying device further includes a curved display panel and an operation processor. The curved display panel is disposed adjacent to the planar display panel and adapted to display a curved image. The operation processor is electrically connected to the curved display panel and the planar display panel. The operation processor is adapted to distort the plane image in accordance with standards of the planar display panel and the curved display panel. The vision watches a combination of the curved image and the distorted plane image to show curved displaying efficiency when the vision focuses on the curved display panel and the planar display panel.
According to the claimed invention, the image displaying device further includes a first display panel and a second display panel. The first display panel is disposed on a side of the planar display panel. The second display panel is disposed on the other side of the planar display panel opposite to the first display panel. When the vision watches the first display panel and the second display panel and passes through the light penetrating unit toward the planar display panel, the vision acquires a distance of an imaging position of the planar display panel relative to the image displaying device is greater than each of two distances of two imaging positions of the first display panel and the second display panel respectively relative to the image displaying device.
The image displaying device of the present invention can provide several embodiments to show the curved displaying efficiency via the planar display, and have advantages of simple structure and low manufacturing cost. The first embodiment can divide the specific-designed planar display panel into several pixel groups along the specific direction, and the pixel distribution density of one pixel group can be different from the pixel distribution density of other pixel groups. The second embodiment can have the planar display panel with the uniform pixel distribution density, and the specific-designed optical lens module can be disposed before the planar display panel; the optical lens module can have the plurality of lens units, and the central lens group has the longest focal length, and the focal length of other lens groups can be gradually decreased from the center to the side of the plurality of lens units. The third embodiment can utilize the software compensation to adjust all partitions of the plane image via different distortion. The fourth embodiment can dispose the plane-concave lens or the convex lens before the planar display. The fifth embodiment can dispose the plane-concave lens or the convex lens before at least one of the planar display and the curved display.

The planar display panel 12 can be divided into several pixel groups along a lateral direction. For example, the planar display panel 12 may at least include a first pixel group PxG1, a second pixel group PxG2 and a third pixel group PxG3. The second pixel group PxG2 can be located between the first pixel group PxG1 and the third pixel group PxG3. An optical feature of the light penetrating unit 14 can be varied in accordance with embodiments of the planar display panel 12. In the first embodiment, the light penetrating unit 14 can be passed through by a light beam, and cannot scatter or condense the light beam. Distribution density of the second pixel group PxG2 can be greater than distribution density of the first pixel group PxG1 and distribution density of the third pixel group PxG3. A focal length of the light penetrating unit 14 relevant to the first pixel group PxG1 can be the same as a focal length of the light penetrating unit 14 relevant to the second pixel group PxG2 and a focal length of the light penetrating unit 14 relevant to the third pixel group PxG3.
In the first embodiment, the light penetrating unit 14 can be a transparent plane surface glass which provides waterproof and dustproof protection, or any optical component with the same or similar functions, and the detailed description is omitted herein for simplicity. Generally, the pixel distribution density can be gradually decreased from a central area (which means the second pixel group PxG2) to two lateral areas (which mean the first pixel group PxG1 and the third pixel group PxG3) of the planar display panel 12; therefore, when the plane image Ip is displayed on the planar display panel 12 and vision V passes through the light penetrating unit 14 toward the planar display panel 12, the vision V can acquire that a second distance D2 of a second imaging position P2 within the plane image Ip relevant to the second pixel group PxG2 relative to the planar display panel 12 is greater than a first distance D1 of a first imaging position P1 within the plane image Ip relevant to the first pixel group PxG1 relative to the planar display panel 12 and a third distance D3 of a third imaging position P3 within the plane image Ip relevant to the third pixel group PxG3 relative to the planar display panel 12, which means the planar display panel 12 of the image displaying device 10A can show curved displaying efficiency.

In the second embodiment, the distribution density of the second pixel group PxG2 can be the same as or similar to the distribution density of the first pixel group PxG1 and the distribution density of the third pixel group PxG3, and the focal length of the second lens group LzG2 can be greater than the focal length of the first lens group LzG1 and the focal length of the third lens group LzG3. Thus, the vision V can acquire the second distance D2 of the second imaging position P2 within the plane image Ip via the second pixel group LzG2 relative to the planar display panel 12 can be greater than the first distance D1 of the first imaging position P1 within the plane image Ip via the first pixel group LzG1 relative to the planar display panel 12 and the third distance D3 of the third imaging position P3 within the plane image Ip via the third pixel group LzG3 relative to the planar display panel 12, so that the planar display panel 12 of the image displaying device 10B can show curved displaying efficiency.
If the lens unit 22 has more than three lens groups, the lens group which is located on a center of the light penetrating unit 14′ can have the largest focal length, and the related imaging position can be set on the farthest position; the focal length of the lens groups which are distributed from the center to two sides of the light penetrating unit 14′ can be gradually decreased, and the related imaging positions can be gradually close to the planar display panel 12. An actual application of distribution of the lens groups is not limited to the above-mentioned embodiment. For example, in other possible embodiments, the first lens group LzG1, the second lens group LzG2 and the third lens group LzG3 can respectively include a plurality of zoomable lens units 22; the operation processor 16 can adjust the focal length of one or some of the lens groups inside the light penetrating unit 14′ in accordance with an actual demand, so as to adjust at least one of a distortion amplitude and a distortion direction of the curved displaying efficiency. Besides, each lens unit 22 of the light penetrating unit 14′ can be a plane-concave lens or a convex lens, and a plane surface or a convex surface of the light penetrating unit 14′ can face toward the planar display panel 12. All the lens units 22 of the light penetrating unit 14′ can preferably be the same type; the lens unit 22 shown in

The operation processor 16 can acquire the original image Io, and divide the original image Io into a first area R1 and a second area R2 in accordance with standards of the curved display panel 24 and the planar display panel 12. The first area R1 can be represented as the curved image Ic directly showed on the curved display panel 24. The second area R2 can be distorted and showed on the planar display panel 12. For example, if the curved display panel 24 is the 32-inch curved display and the planar display panel 12 is the 22-inch planar display, the curved display panel 24 and the planar display panel 12 have the same or similar height, and a width of the curved display panel 24 is two times a width of the planar display panel 12; in the meantime, the operation processor 16 can define two third of the original image Io as the first area R1 an further define one third of the original image Io as the second area R2 along the lateral direction; an actual application of division among the original image Io is not limited to the above-mentioned embodiment, which depends on the design demand.
In the third embodiment, the operation processor 16 can further divide the second area R2 of the original image Io into several partitions along a specific direction (such as the lateral direction), and utilize different distortion to adjust image data of each partition; for example, the central partition has largest distortion, and distortion of other partitions can be gradually decreased from the center to the side of the second area R2. Distortion of each partition can be varied in accordance with the image curvature of the curved image Ic, so that the curved displaying efficiency performed by the distorted plane image Ip can be matched with the curved image Ic. The foresaid distortion may represent lateral deformation of each partition; however, deformed direction is not limited to the above-mentioned embodiment, and depends on the actual demand. For example, the second area R2 may be at least divided into a first partition S1, a second partition S2 and a third partition S3. Distortion of the second area R2 can be greater than distortion of the first partition S1 and the third partition S3. Therefore, the vision V can acquire that the second distance D2 of the second imaging position P2 generated by the second partition S2 can be greater than the first distance D1 of the first imaging position P1 generated by the first partition S1, and the third distance D3 of the third imaging position P3 generated by the third partition S3.
As the embodiment shown in
In the third embodiment, the curved display panel 24 can be connected to the planar display panel 12 in a rotatable manner or in a detachable manner. The said rotatable application may be a rotary mechanism, a pin mechanism, or a movable engagement mechanism; the said detachable application may be a locking mechanism, a buckling mechanism or a magnetic mechanism. Variation of the rotatable application and the detachable application is not limited to the above-mentioned embodiments, which depends on the design demand.

When the vision V directly watches the first display panel 28 and the second display panel 30, and passes through the light penetrating unit 14 toward the planar display panel 12, the vision V can acquire that a distance of an imaging position performed by the planar display panel 12 relative to the front of the image displaying device 10D (which may be an outer side of the front frame 18) can be greater than each of two distances of two imaging positions performed by the first display panel 28 and the second display panel 30 respectively relative to the front of the image displaying device 10D, so the image displaying device 10D can show the preferred curved displaying efficiency.
The fourth embodiment can utilize the light penetrating unit 14 (which may be the plane-concave lens or the convex lens) to distort the plane image Ip of the planar display panel 12 via hardware compensation for showing the curved displaying efficiency, instead of software compensation in the foresaid embodiments that analyze and adjust the areas and partitions of the original image Io by the operation processor 16. However, the present invention may simultaneously utilize the hardware compensation and the software compensation to show the preferred curved displaying efficiency in a combination of the planar display and the curved displays.
In the fourth embodiment, difference between a width of the light penetrating unit 14 and a width of the planar display panel 12 can be smaller than a predefined tolerant value, which means the light penetrating unit 14 and the planar display panel 12 can have the same or similar width. An actual value of the predefined tolerant value can be designed in accordance with the size of the image displaying device 10D, and a detailed description is omitted herein for simplicity.

Further, if the first display panel 28′ and the second display panel 30′ are the curved display, the auxiliary lens unit 34 can still be disposed on the front of the curved display, and the related embodiment is not shown in the figures. Any design capable of having the focal length of the auxiliary lens unit 34 smaller than the focal length of the light penetrating unit 14 to show the preferred curved displaying efficiency when the vision V passes through the light penetrating unit 14 and the auxiliary lens unit 34 respectively toward the planar display panel 12 and the first display panel 28′ and the second display panel 30′ can conform to a design scope of the present invention.
