Description
Technical Field
The invention relates to the technical field of image display, in particular to an image display method and a display device of a micro display chip.
Background
The Micro-LED or Micro-OLED based Micro display technology is a display technology which takes self-luminous micrometer-scale LEDs or OLEDs as light-emitting pixel units and assembles the light-emitting pixel units on a driving panel to form a high-density LED array. Due to the characteristics of small size, high integration level, self-luminescence and the like of the micro-display chip, the micro-display chip has great advantages in the aspects of display brightness, resolution, contrast, energy consumption, service life, response speed, thermal stability and the like. Based on the above advantages, the micro display chip based display device can be manufactured as a miniature and portable product, which makes the micro display chip based display device applicable to AV or VR display devices.
The mainstream projection technical route in the prior art mainly includes: DLP technology, three-chip or monolithic LCD technology, and LCOS technology. In the above projection technology, in order to meet the brightness requirement of the display screen, a light source system with a larger size is usually required to be arranged to ensure the screen display brightness during long-distance projection. This has led to the fact that projection systems based on the above-mentioned technical route are not applicable to miniature and portable devices.
The current Micro-LED or Micro-OLED large-size display panel manufacturing process usually uses a huge transfer technology to correctly and effectively transfer several million pixel-level LED dies from a carrier substrate to a driving circuit substrate. The greater the number of LED dies that need to be transferred, the higher the cost of manufacturing the microdisplay chip, and the more the microdisplay chip is geometrically multiplied.
Meanwhile, for Micro display chips of Micro-LEDs or Micro-OLEDs, the Wafer To Wafer bonding technology or the Chip To Chip bonding technology is generally adopted at present. The micro display chip size is typically between 0.3 inches and 1.0 inches. It is very difficult to fabricate high resolution pixels on such a small chip, and the larger number of LED pixels fabricated on the same area of the chip leads to more significant sidewall effect, thereby seriously affecting the display effect. It is currently possible in the art to achieve 1280 × 1024 resolution on a 0.6 inch chip.
As can be seen from the above, how to implement high-resolution image display by using the existing low-resolution microdisplay chip is a technical problem to be solved in the prior art.

Example 1
As shown in fig. 1, a schematic physical pixel structure diagram of a micro display chip in this embodiment is that the micro display chip in this embodiment includes a pixel array formed by a plurality of physical pixels in X rows and Y columns, each physical pixel includes four sub-pixel positions formed by two rows and two columns, and the four sub-pixel positions are a first quadrant sub-pixel position, a second quadrant sub-pixel position, a third quadrant sub-pixel position, and a fourth quadrant sub-pixel position, respectively. The four sub-pixel positions have the same shape, and in this embodiment, the first quadrant sub-pixel position, the second quadrant sub-pixel position, the third quadrant sub-pixel position, and the fourth quadrant sub-pixel position are all squares with the same size. One of a red light LED unit (R), a green light LED unit (G) and a blue light LED unit (B) is arranged on the first quadrant sub-pixel position, the second quadrant sub-pixel position, the third quadrant sub-pixel position and the fourth quadrant sub-pixel position, two sub-pixel positions of the first quadrant sub-pixel position, the second quadrant sub-pixel position, the third quadrant sub-pixel position and the fourth quadrant sub-pixel position are set as red light LED units, one of the other two sub-pixel positions is set as a green light LED unit, and the other one is set as a blue light LED unit. And a preset RGB light-emitting unit corresponding rule is arranged between the four sub-pixel positions and the RGB light-emitting units, and all the physical pixels adopt the same RGB light-emitting unit corresponding rule. The RGB light-emitting unit correspondence rule means that one RGB light-emitting unit is configured with the four sub-pixel positions fixed, for example, in this embodiment, the red LED unit (R) is configured at the first quadrant sub-pixel position and the second quadrant sub-pixel position, the blue LED unit (B) is configured at the third quadrant sub-pixel position, and the green LED unit (G) is configured at the fourth quadrant sub-pixel position. In another embodiment, the red LED units (R), the blue LED units (B), and the green LED units (G) may be disposed at the first quadrant sub-pixel positions and the fourth quadrant sub-pixel positions. Namely, the corresponding rule of the RGB light-emitting units is not unique, and meanwhile, two red LED units (R) are arranged in four sub-pixel positions to make up the defect of low external quantum efficiency of the red LED.
In this embodiment, as shown in fig. 2, the micro-LED micro display chip is horizontally moved by disposing an optical vibrating device at the front of the micro-LED micro display chip. The optical vibration device includes a planar lens, both surfaces of which are planar, as shown in fig. 2, when light is perpendicularly incident to the planar lens, the light is not deflected but is emitted in the original incident direction, and when the planar lens deflects at a reflection angle, the direction of the emergent light is deflected from the direction of the incident light according to the law of refraction of the light. As shown in fig. 3, the shift amount Δ x satisfies the following relationship with the refractive index n of the planar lens, the thickness d of the planar lens, and the deflection angle θ of the planar lens:
according to the above formula, when the planar lens is deflected horizontally or vertically by the deflection angle θ, each physical pixel of the display screen of the micro display chip is displaced by Δ x in the horizontal or vertical direction. As shown in fig. 3 to 6, in the present embodiment, the optical vibrator is switched among the non-deflected state, the first deflected state, the second deflected state, and the third deflected state by setting different horizontal deflection angles θ. Specifically, the non-deflected state is a state in which the deflection angle θ is 0, the first deflected state is a state in which the planar lens is deflected by the angle θ in the horizontal direction, the second deflected state is a state in which the planar lens is simultaneously deflected by the angle θ 'in the vertical direction in the first deflected state, and the third deflected state is a state in which the planar lens is deflected by the angle θ' in the vertical direction. In the present embodiment, the pixel formed in the first deflection state is shifted by Δ x equal to the horizontal width of one sub-pixel position by setting the appropriate deflection angle θ, and similarly, the pixel in the second deflection state is shifted by Δ x equal to the horizontal width of one sub-pixel position and by Δ x equal to the vertical width of one sub-pixel position by setting the appropriate vertical deflection angle θ'.
The horizontal direction is a horizontal direction in which the pixel arrays of the micro-LED micro-display chips are arranged, specifically, the horizontal direction is a left-to-right arrangement direction in this embodiment, and the vertical direction is a vertical direction in which the pixel arrays of the micro-LED micro-display chips are arranged, specifically, the vertical direction is a top-to-bottom arrangement direction in this embodiment, that is, the pixels at the top left corner of the micro-LED micro-display chips are defined as pixels in a first row and a first column.
Fig. 7 to 8 are schematic structural views of the optical vibration device in the present embodiment, which includes a first frame 1, a second frame 2, a planar lens 3, a permanent magnet 4, and an electromagnet 5.
