Problems solved by technology

The high-resolution field of view of the Varjo prototype is about 20°, which is fixed at the center of the field of view. In the future, integrated eye tracking technology will be added to dynamically adjust the reflected image of the micro-display. Its structure is obviously relatively complicated.

Embodiment 1

[0049] Embodiment 1: Micro-displacement OLED display screen.

[0050] A 2K AMOLED display screen with a resolution of 2560×1440 is adopted. The pixels of the screen are arranged in PenTile. The display screen (6) is softly connected to the main control board and other components through wires. The support point of the display screen (6) is linked to the micro-displacement drive mechanism (8 )superior. The micro-displacement trajectory can be decomposed into two circles with a radius of 0.707d and a broken-line displacement with a length of 0.707d, such as Figure 9 As shown, it is jointly driven by two modes of rotating shaft circumference and linear reciprocation. Under the control of the drive circuit (9), it moves periodically according to a predetermined trajectory. First, the circular motion moves from node ①→node ②→node ③→node ④ to the circular position node ④. After the refresh of the sub-image 4 is completed, the display screen ( 6) Move a distance of 0.707d to the u...

Embodiment 2

[0051] Embodiment 2: micro-displacement LCD display screen.

[0052] A 5.5-inch 4K LCD display with a resolution of 3840×2160 is used. The screen pixels are arranged in standard RGB. The display (6) is connected to the main control board and other components through soft lines. The support points of the display (6) are linked to the micro-displacement drive Bodies (8) on. The micro-displacement approximates a 6-node closed polyline with an elliptical trajectory, such as Image 6 As shown in B, the elliptical motion can be decomposed into simple harmonic vibration in the X direction and the Y direction, and the micro-displacement adopts X / Y axis bidirectional drive, and moves periodically according to the elliptical trajectory under the control of the drive circuit (9), from node ①→ Node ②→Node ③→Node ④→Node ⑤→Node ⑥→Node ①, refresh one frame of high-definition image in turn, and start displaying the next frame of high-definition image. N=3*2, f 0 =240Hz, the resolution of m...

Embodiment 3

[0053] Embodiment 3: micro-displacement blue-phase liquid crystal screen.

[0054] The resolution of the blue-phase liquid crystal display is 8K, which is composed of monochrome pixels arranged in a standard dot matrix. The field sequence displays R, G, and B colors in sequence. The response time of the blue-phase liquid crystal is short, and the basic refresh rate can be set higher. For example, if the monochrome refresh reaches 960Hz, the color can reach 320Hz. There is a gap between monochrome pixels, and a pixel can be inserted through a micro-displacement. The display screen (6) is softly connected with the main control board and other components through lines, and the support point of the display screen (6) is linked to the micro-displacement drive mechanism (8), and the micro-displacement track is a circle, such as Figure 5 As shown, the micro-displacement is driven by the circumference of the rotating shaft. Under the control of the drive circuit (9), it moves periodi...

Abstract

The invention discloses a micro-displacement VR display screen which is composed of a display screen, a micro-displacement display App module, a micro-displacement driving mechanism and a driving circuit. By combining a fixation point rendering technology, existing software and hardware resources can be fully utilized, under the condition that data flow and operation burden are not greatly increased, image definition is greatly improved, VR retina resolution display is achieved, and the screen window effect of the image is eliminated. Compared with an existing VR head-mounted display, the VR head-mounted display has a wider visual field and higher definition, and enables an image to truly show three-dimensional, immersion and tentacle reachable feelings.

Description

Technical field: [0001] The present invention relates to a VR display screen, and more specifically, to a VR display screen that realizes high-definition display through micro-displacement. The display screen can combine foveated point rendering technology to realize VR retinal resolution display. Background technique: [0002] As a virtual reality display terminal, the VR helmet-mounted display magnifies the image generated by the VR display through the optical system. The light emitted by the VR display passes through a convex lens to make the image refracted to produce a similar distant effect, and use this effect to enlarge nearby objects. View from a distance to achieve the so-called immersive vision. VR head-mounted display is referred to as VR head-mounted display, and its representatives are Oculus Rift, Sony's PlayStation VR, and HTC / Valve's VIVE). [0003] The primary factor that determines the VR effect is the resolution of the VR display. For existing VR displa...
