Description

Technical Field

[0001] The present invention relates to a micro light emitting diode display, in particular to a display with variable pixel density. Background Art

[0002] Micro LED is an emerging display technology that consists of even smaller light-emitting chips. Compared with existing light-emitting diode (LED) or organic light-emitting diode (OLED) display technologies, micro LED has higher brightness, contrast and color expression, as well as higher energy efficiency and long life.

[0003] Compared with existing display technologies, micro-LEDs have many advantages. The first is brightness and contrast. The brightness of micro-LEDs can be more than 10 times that of ordinary organic light-emitting diodes, and the contrast is also higher. This makes micro-LED displays significantly improved in color reproduction and image quality.

[0004] Continuing from the above, the advantage of micro-LEDs is secondly the color expression. Since the micro-LED display uses a pure light source, it can display a wider color gamut, thus providing more realistic and vivid colors. At the same time, the micro-LED display can also achieve local dimming, which means that it can achieve independent brightness adjustment of different areas on the same screen, thus achieving better contrast and energy efficiency.

[0005] Continuing from the above, the third advantage is the energy efficiency and longer lifespan, and the micro-LED uses a pure light source, so there is no need for a backlight and a color filter layer, thereby improving the light output efficiency.

[0006] Due to the advantages of micro-LEDs, it has become the preferred technology for many high-end display products, including smartphones, tablet computers, TVs, car dashboard displays, VR / AR / MR head-mounted displays, etc.

[0007] With the rise of VR / AR / MR head-mounted displays, the pixels of the display are easily visible due to their proximity to the human eye, which results in a grid effect. Therefore, the industry is gradually moving towards higher quality and higher resolution displays, making micro-LED technology increasingly popular. Compared with traditional LCDs, LEDs, and OLEDs, micro-LEDs have higher brightness and better contrast, as well as a wider color space, and are therefore considered an important development direction for the next generation of display technology.

[0008] The advantages of micro-LEDs also lie in reliability and long-term cost of use. Due to their long life and high durability, micro-LEDs are more economical than other technologies, and due to their low power consumption and long life, they can maintain high-quality displays for a long time.

[0009] However, although conventional micro-LEDs are tiny in size and can further improve the pixel density (resolution) of near-eye displays such as VR, AR, and MR, while increasing pixel density, it also increases power consumption and manufacturing costs. High-pixel-density displays also further reduce the yield of finished products and increase response time. Therefore, the industry needs a micro-LED display that can solve the above-mentioned conventional problems.

[0010] In view of the above problems of the prior art, the present invention provides a micro light emitting diode display, which divides the display panel into at least two display areas, wherein pixels in one display area individually receive a control signal, and multiple pixels in the other display area receive another control signal.

[0035] See also FIG. 3A to FIG. 3B , which is an active control schematic diagram of the second embodiment of the present invention.

[0037] Continuing from the above, in this embodiment, the first control unit 24 transmits the first control signal to the red light emitting element R, the green light emitting element G and the blue light emitting element B of the first sub-pixel 22 to control and drive the first sub-pixel 22 to emit light of different colors (including white light).

[0038] Continuing from the above, in this embodiment, the second control unit 34 simultaneously transmits the second control signal to the red light emitting element R, the green light emitting element G and the blue light emitting element B of the respective second sub-pixels 32 to control and drive the second sub-pixels 32 to emit light of different colors (including white light).

[0039] Continuing from the above, in this embodiment, the single second control unit 34 controls the second sub-pixels 32 simultaneously, which can reduce the use of control components in the second display area A2, further reduce the manufacturing cost of the micro-LED display 1, and improve the finished product yield of the micro-LED display 1.

[0040] Continuing from the above, in this embodiment, the first control unit 24 and the second control unit 34 adopt active drive (Active Matrix), such as a micro light emitting diode (Micro LED) display, in which the transistor array on the backplane controls the switching current and drives the pixels; the first control unit 24 and the second control unit 34 can be silicon transistors or thin film transistors. Silicon transistors can be made very small, and the manufactured backplane transistors have an extremely small pitch, which is suitable for high-resolution VR, AR, and MR displays. Thin film transistors (TFT) can be made of amorphous silicon, low-temperature polycrystalline silicon (LTPS) or indium gallium zinc oxide (IGZO). Thin film transistors can be manufactured on substrates of larger sizes than silicon transistors, which can further reduce the cost per unit area.

[0041] See also FIG. 4A to FIG. 4B, which is a passive control schematic diagram of the third embodiment of the present invention. As shown in the figure, this embodiment is the third embodiment. This embodiment is based on the above-mentioned first embodiment. In this embodiment, the panel 10 further includes a row driving circuit 50 and a column driving circuit 52. The row driving circuit 50 is electrically connected to the first sub-pixels 22 respectively included in the first pixel 20, and the row driving circuit 50 is electrically connected to the second sub-pixels 32 respectively included in the second pixel 30. The column driving circuit 52 is electrically connected to the first sub-pixels 22 respectively included in the first pixel 20, and the column driving circuit 52 is electrically connected to the second sub-pixels 32 respectively included in the second pixel 30. The row driving circuit 50 and the column driving circuit 52 transmit the first control signal to the first sub-pixels 22 respectively included in the first pixel 20, and the row driving circuit 50 and the column driving circuit 52 transmit the second control signal to the second sub-pixels 32 respectively included in the second pixel 30.

[0042] Continuing from the above, in this embodiment, the second sub-pixels 32 of the single second pixel 30 receive the same control at the same time, which can reduce the usage of the driving circuit of the second display area A2, reduce its wiring range, further reduce the manufacturing cost of the micro-LED display 1, and improve the finished product yield of the micro-LED display 1.

[0043] Continuing from the above, the passive driving (Passive Matrix) is adopted in the present embodiment, wherein the anode (P-electrode) of each column of pixels in the array is connected to the column scan line (Data Current Source), and the cathode (N-electrode) of each row of pixels is connected to the row scan line (Scan Line) to control the first sub-pixel 22 included in the first pixel 20 to emit light, and control the second sub-pixels 32 included in the second pixel 30 to emit light, and use the second control signal to make the second sub-pixels 32 included in the second pixel 30 emit light of the same wavelength (including white light).

[0044] Continuing from the above, in this embodiment, the panel further includes a driving element 60 . The driving element 60 is electrically connected to the row driving circuit 50 and the column driving circuit 52 to transmit the first control signal and the second control signal.

[0045] See also Figure 5, which is a schematic diagram of a light-emitting display of an embodiment of the present invention. As shown in the figure, this embodiment is a schematic diagram of the display of the first, second and third embodiments mentioned above. The first pixel 20 of the first display area A1 can emit different light rays to generate multiple pixel points individually. Similarly, the second pixel 30 of the second display area A2 can also emit different light rays to generate multiple pixel points individually. It should be noted that the second pixel 30 includes a plurality of second sub-pixels 32, which are a plurality of second sub-pixels 32 combined to form a pixel point, so that a second resolution of the picture displayed in the second display area A2 is smaller than a first resolution of the picture displayed in the first display area A1. Because the second display area A2 corresponds to an area where the human eye has poor judgment ability, the second display area A2 with a lower resolution can further reduce power consumption. The second display area A2 with a lower control component requirement (such as the second and third embodiments) also reduces the manufacturing cost of the micro-light emitting diode display 1.

[0046] See also Figure 6 , which is a schematic diagram of pixel density of an embodiment of the present invention. As shown in the figure, this embodiment may correspond to the first, second and third embodiments mentioned above. In this embodiment, the first sub-pixel 22 of the first pixel 20 of the first display area A1 has a first pixel density, and the second sub-pixels 32 of the second pixel 30 of the second display area A2 have a second pixel density. The first pixel density is greater than the second pixel density, that is, the spacing between the multiple second sub-pixels 32 distributed in the second display area A2 is greater than the spacing between the multiple first sub-pixels 22 distributed in the first display area A1. This structure further reduces the usage of light-emitting elements in the second display area A2, reduces manufacturing costs and improves the yield of the display.

[0047] See also Figure 7 , which is a schematic diagram of the third display area of ​​an embodiment of the present invention. As shown in the figure, this embodiment is based on the above-mentioned first embodiment. In this embodiment, it further includes a third display area A3. The third display area A3 is provided with a third pixel 40, that is, the third pixel 40 is provided in the third display area A3. The third pixel 40 individually includes a plurality of third sub-pixels 42. The third pixel 42 receives a third control signal. The other component relationships of this embodiment are the same as those of the above-mentioned first embodiment, so they are not repeated here.

[0048] Continuing with the above, in this embodiment, the first display area A1 covers an outer side of the third display area A3, the second display area A2 covers an outer side of the first display area A1, and the first display area A1 corresponds to 5° to 30° of the human eye viewing angle, the second display area A2 corresponds to 30° to 60° of the human eye viewing angle, and the third display area A3 corresponds to 0° to 5° of the human eye viewing angle, wherein the third sub-pixels 42 of the third pixel 40 of the third display area A3 have a third pixel density, and the third pixel density is greater than the second pixel density, and the first pixel density is greater than the third pixel density, forming a display panel with sparse and dense layout toward the center point to adapt to the viewing angle of the human eye and reduce the manufacturing cost of the display panel.

[0049] Continuing from the above, the horizontal viewing angle of human eyes can reach 188°, of which the overlapping area (field of view) that can be seen by both eyes is about 124°, that is, within the range that the human eye can see, only objects within this 124° have a three-dimensional sense. The center axis from the binocular viewpoint to the middle of the human eye can be defined as 0°, that is, the left and right sides of the human eye's viewing angle are 62° and -62° respectively. Because the comfortable area of ​​​​monocular rotation of the human eye is about -30° to 30°, objects within this 60° range can be seen clearly and focused, and the peripheral part beyond 30° (or -30°) from the gaze point is called peripheral vision, commonly known as the peripheral light of the eye, which is actually a range that the human eye is not sensitive to, that is, an area that cannot be seen clearly. Therefore, in the above implementation, the first display area A1 with the highest pixel density corresponds to 5° to 30° of the human eye's viewing angle, and the second display area A2 with the lowest pixel density corresponds to 30° to 60° of the human eye's viewing angle, thereby reducing the manufacturing cost of the display and reducing energy consumption.

[0050] Continuing with the above, when applied to near-eye displays, since the display is close to the human eye, the panel 10 of the display has an area between the eyes (in front of the bridge of the nose) that cannot be seen clearly. Therefore, in the above embodiment, a third display area A3 with the second lowest density is further provided. The third display area A3 corresponds to 0° to 5° of the human eye viewing angle, thereby reducing the manufacturing cost of the display and reducing energy consumption.

[0051] See also FIG. 8A to FIG. 8B, which is a schematic diagram of a multi-layer panel structure of an embodiment of the present invention. As shown in the figure, this embodiment is based on the above-mentioned first embodiment. In this embodiment, it further includes a third display area A3, and the third display area A3 is provided with a third pixel 40, that is, the third pixel 40 is provided in the third display area A3, and the third pixel 40 includes a plurality of third sub-pixels 42 respectively. The third pixel 42 receives a third control signal, and the panel is provided with a P-type electrode layer P and an N-type electrode layer N. The P-type electrode layer P is electrically connected to the first sub-pixel 22, the second sub-pixels 32 and the third sub-pixels 42, and the N-type electrode layer N is provided at the panel 10. An outer edge, the N-type electrode layer N is electrically connected to the first sub-pixel 22, the second sub-pixels 32 and the third sub-pixels 42 respectively. In the present embodiment, the panel 10 comprises multiple layers, and the N-type electrode layer N is electrically connected to the N-type electrode layer N of another panel 10' at a certain position 11 of the panel 10, that is, the N-type electrode layer N of the panel 10 at the positioning point 11 is electrically connected to the N-type electrode layer N of another panel 10' at its positioning point 11', so that the panel 10 and the panel 10' are stacked on each other to form a display panel with vertically stacked light-emitting elements. The other component relationships of the present embodiment are the same as those of the first embodiment mentioned above, so they are not repeated here.

[0052] Continuing from the above, in this embodiment, the N-type electrode layer N of the panel 10 is electrically connected to the N-type electrode layer N of another panel 10 ′ in a fan-out package.

[0053] Continuing from the above, in this embodiment, the positioning point 11 of the panel 10 is disposed at the outer edge of the panel 10 , but the present invention is not limited thereto.

[0054] Continuing with the above, in this embodiment, the area of ​​the positioning point 11 of the panel 10 is larger than the area of ​​the positioning point 11 of the panel 10', that is, the panel 10' below the panel 10 is also provided with the positioning point 11 at the outer edge, and the area of ​​the positioning point 11 of the panel 10' needs to be smaller than the area of ​​the positioning point 11 of the panel 10, so that after the two panels are stacked on each other, it is easier to find the positioning point 11 located above / below so that the N-type electrode layer N can be further provided with wires to be electrically connected to each other, thereby avoiding the situation where it is difficult to position.

[0055] Continuing from the above, in one embodiment, the stacked panels 10 / 10 ′ are not limited to stacking two layers, but may further stack a third layer or more layers.

[0056] In summary, the present invention provides a micro-light emitting diode display, which reduces the control elements of a partial area (second display area) on the panel or controls the resolution of the partial area with an addressing signal, thereby reducing the resolution of the partial area of ​​the display. The area corresponds to the area that is difficult for the human eye to notice (such as the periphery of the visual field), further reducing the power consumption of the display and reducing the manufacturing cost of the display. Since the panel of the display reduces the control elements or reduces the circuit configuration, the finished product yield of the display can be relatively improved and the response time of the display image can be reduced. This structure solves the problems of excessive energy consumption and high manufacturing cost of conventional near-eye displays.
