This application claims the priority benefit of Taiwan application serial no. 111105587, filed on Feb. 16, 2022. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this specification.
The invention relates to a display system and a display method thereof, and in particular, to a naked-eye stereoscopic display system and a display method thereof.
In recent years, the concept of display panel research and development is directed towards a “natural vision” stereoscopic display system, that is, a naked-eye stereoscopic display system. Naked-eye stereoscopic display systems have various applications in the market, such as smart medical display systems such as telesurgery. Medical applications require good image quality. However, the naked-eye stereoscopic display system currently on the market has the issue of image crosstalk, so that the presented images may not be detailed enough.
The invention provides a naked-eye stereoscopic display system and a display method thereof that may effectively reduce the issue of crosstalk.
An embodiment of the invention provides a naked-eye stereoscopic display including a display system, an optical element, and a controller. The display is adapted to emit a plurality of image beams, and includes a plurality of display regions. Each of the display regions includes a plurality of first sub-display regions and a second sub-display region. A light configuration is performed on the image beams by the optical element, and then the image beams are projected out of the naked-eye stereoscopic display. The controller is electrically connected with the display. The controller controls the display, so that a light intensity of an image beam generated by the first sub-display regions is lower than a light intensity of an image beam generated by the second sub-display region.
An embodiment of the invention provides a display method of a naked-eye stereoscopic display system that includes the following steps. A plurality of image beams are emitted using a display, wherein the display includes a plurality of display regions, and each of the display regions includes a plurality of first sub-display regions and a second sub-display region. The controller controls the display, so that a light intensity of an image beam generated by the first sub-display regions is lower than a light intensity of an image beam generated by the second sub-display region.
Based on the above, in the naked-eye stereoscopic display system or the display method thereof of an embodiment of the invention, since the light intensity of the image beam generated by the first sub-display regions is smaller than the light intensity of the image beam generated by the second sub-display region, the issue of crosstalk between the edges of the display regions is effectively alleviated, so that the naked-eye stereoscopic display system or the display method thereof may provide stereoscopic images of better quality.
In the present embodiment, the image beams IB and IB′ pass through the optical element 200 and then are projected out of the naked-eye stereoscopic display system 10 and transmitted to the eyes E and E′ of the viewer. In
In an embodiment, the optical element 200 may be a microlens array or a parallax barrier, wherein
In the present embodiment, the first sub-display regions DR1 are located at the periphery of the second sub-display region DR2, the second sub-display region DR2 is located at the center region of each of the display regions DR, and a width W1 of the first sub-display regions DR1 is smaller than a width W2 of the second sub-display region DR2. In particular, the number of the first sub-display regions DR1 is an even number.
In addition, when the number of the first sub-display regions DR1 is larger, the effect of the naked-eye stereoscopic display system 10 in alleviating the crosstalk issue is better, but the computational burden of the controller 300 is also increased. Therefore, in a preferred embodiment, the number of the first sub-display regions DR1 falls within the range of 1 to 5. Alternatively, the ratio between the width W2 of the second sub-display region DR2 and the width W1 of the first sub-display regions DR1 falls within the range of 1.0 to 10.
In an embodiment, the controller 300 includes, for example, a central processing unit (CPU), a microprocessor, a digital signal processor (DSP), a programmable controller, a programmable logic, a programmable logic device (PLD), other similar devices, or a combination of these devices, and the invention is not limited thereto. Moreover, in an embodiment, each function of the controller 300 may be implemented as a plurality of program codes. These program codes are stored in one memory unit, and the program codes are executed by the controller 300. Alternatively, in an embodiment, each function of the controller 300 may be implemented as one or a plurality of circuits. The invention does not limit whether each function of the controller 300 is implemented in software or hardware form.
Based on the above, in an embodiment of the invention, the display 100 of the naked-eye stereoscopic display system 10 includes the plurality of display regions DR and DR′. Each of the display regions DR includes the plurality of first sub-display regions DR1 and the second sub-display region DR2. In particular, the controller 300 controls the display 100, so that the light intensity of the image beam IB′ generated by the first sub-display regions DR1 is lower than the light intensity of the image beam IB generated by the second sub-display region DR2. Therefore, the issue of crosstalk between the edges of the display regions DR and DR′ is effectively alleviated, so that the stereoscopic image quality of the naked-eye stereoscopic display system 10 is better.
Based on the above, in the naked-eye stereoscopic display system or the display method thereof according to an embodiment of the invention, the display includes a plurality of display regions. Each of the display regions includes a plurality of first sub-display regions and a second sub-display region. Since the light intensity of the image beam generated by the first sub-display regions is smaller than the light intensity of the image beam generated by the second sub-display region, the issue of crosstalk between the edges of the display regions is effectively alleviated, so that the naked-eye stereoscopic display system or the display method thereof may provide stereoscopic images of better quality.
