Description

TECHNICAL FIELD

[0002] Micro-LED refers to a micro-sized LED (generally less than 50 μm) formed by miniaturizing a traditional LED, which can realize a display array with super-high-density pixel resolution. Micro-LED has the characteristics of self-emission, and compared with OLED, Micro-LED is easier to accurately debug, has a longer light-emitting life and higher brightness, and is small in light-mechanical size, thin, and low in cost, which makes Micro-LED an ideal choice for micro-display applications. A micro-sized or even nanometer-sized LED array is the only high-luminous-efficiency low-power-consumption device that integrates driving, light-emitting, and signal transmission, and realizes a super-large-scale integrated light-emitting unit display device, which combines the two major technical features of LCD and OLED, and has much better performance than the current TFT-LCD (Thin Film Transistor) or OLED, and is more widely applied.

[0003] The core technology of Micro-LED is the transfer and bonding of LED chips in a small size, and for realizing color display, a large number of three separate μLED devices need to be transferred to the same driving substrate, and the transfer rate and yield in the transfer process are the technical bottlenecks for realizing the industrialization of Micro-LED. At the same time, for realizing high-resolution Micro-LED display, it means more pixel points and signal wiring design, so that the driving integrated circuit is more complex. In the process of simplifying the driving integrated circuit, the influence of the Micro-LED light-emitting time on the final imaging quality needs to be considered. SUMMARY

[0004] Through the applicant's research: through the design of a special pixel circuit structure and driving waveform and driving system, two different Micro-LED sub-pixels can share the same data lead.

[0025] The application discloses a driving method of a color Micro-LED device structure sharing data leads, and those skilled in the art can refer to the content herein and appropriately improve technical details for implementation. It should be particularly pointed out that all similar replacements and changes are obvious to those skilled in the art, and they are all regarded as included in the application. The method and application of the application have been described by the preferred embodiments, and relevant personnel can obviously modify or appropriately change and combine the method and application described herein without departing from the content, spirit and scope of the application, to realize and apply the application technology.

[0026] Through special pixel circuit structure and the design of driving waveform and driving system, two different Micro-LED sub-pixels can share the same data lead wire.

[0027] Therefore, the embodiment of the present application provides a color Micro-LED device structure sharing data lead wires, as shown in the figure. Figure 1 The color Micro-LED device structure includes primary color pixel circuit 101, row scanning lead wire 102, column data lead wire 103 and thin film transistor switch 104; the primary color pixel circuit 101 includes two primary color micro light emitting diodes 105 and energy storage capacitor 106, the two primary color micro light emitting diodes 105 are connected in parallel and the electrodes are opposite, the energy storage capacitor 106 is connected in parallel with the primary color micro light emitting diode 105, the energy storage capacitor 106 is used to make the originally light-emitting primary color micro light emitting diode 105 continue to emit light so as to prolong the light-emitting time, one end of the primary color pixel circuit 101 is connected to the drain of the thin film transistor switch 104, and the other end of the primary color pixel circuit 101 is grounded; the gate of the thin film transistor switch 104 is connected with the row scanning lead wire 102, the row scanning lead wire 102 is used to control the gating of the thin film transistor switch 104, and the source of the thin film transistor switch 104 is connected with the column data lead wire 103, the column data lead wire 103 is used to control the brightness of the primary color micro light emitting diode 105 in the primary color pixel circuit 101.

[0028] The primary color micro light emitting diode 105 includes red, green and blue three primary color micro light emitting diodes 105, and three adjacent and different color primary color micro light emitting diodes 105 constitute a light-emitting pixel.

[0029] When the column data lead wire drives the first primary color micro light emitting diode in the primary color pixel circuit 101, the first primary color micro light emitting diode is driven to emit light, the second primary color micro light emitting diode in the primary color pixel circuit 101 does not emit light due to the opposite electrodes, and the energy storage capacitor 106 stores energy at the same time; after the driving is completed, the energy storage capacitor 106 discharges, the first primary color micro light emitting diode continues to emit light, and the second primary color micro light emitting diode does not emit light due to the opposite electrodes.

[0030] In the specific embodiment, when the first primary color micro light emitting diode and the second primary color micro light emitting diode in the same primary color pixel circuit 101 need to be driven together, because the electrode directions of the first primary color micro light emitting diode and the second primary color micro light emitting diode in the primary color pixel circuit 101 are opposite, different direction driving voltages are needed. Therefore, if the first primary color micro light emitting diode needs a forward driving voltage for driving, the second primary color micro light emitting diode needs a negative driving voltage for driving. Therefore, the waveform diagram of the driving voltage can be as shown in Figure 2 The interval time t between the forward driving voltage and the negative driving voltage is one scanning cycle of the row scanning lead 102. When the first primary color micro light emitting diode is driven by the forward voltage, the first primary color micro light emitting diode emits light, the energy storage capacitor 106 is forward charged to make the first electrode plate of the energy storage capacitor 106 carry positive charge and the second electrode plate carry negative charge, and when the forward voltage driving stops, the energy storage capacitor 106 is discharged, and because the first electrode plate is connected to the anode of the first primary color micro light emitting diode, the first primary color micro light emitting diode can continue to reflect light. Similarly, when the second primary color micro light emitting diode is driven by the negative voltage, the second primary color micro light emitting diode emits light, the energy storage capacitor 106 is forward charged to make the second electrode plate of the energy storage capacitor 106 carry positive charge and the first electrode plate carry negative charge, and when the negative voltage driving stops, the energy storage capacitor 106 is discharged, and because the second electrode plate is connected to the anode of the second primary color micro light emitting diode, the second primary color micro light emitting diode can continue to reflect light.

[0031] The embodiment of the present application can not only ensure that the light emitting time length meets the image quality requirements, but also reduce the data lead.

[0033] The color Micro-LED device structure corresponding to the first specific embodiment can be as shown in Figure 3 . Figure 3 In the figure, the colors of the respective primary color micro light emitting diodes 105 have been marked, and 301 and 302 respectively represent a light emitting pixel.

[0034] It should be noted that the blue micro-LED and the green micro-LED share one data lead because they both belong to the InGaN material system, although the photoelectric properties are not completely consistent but similar, and the turn-on voltage is between 2.5-3V, and different turn-on voltages can be realized through the design of the driving waveform and the driving system. Such a design can make the driving voltage flip easier and the driving simpler.

[0035] Further, in the second specific embodiment, as shown in Figure 4 , the blue micro-LED and the green micro-LED in the blue-green primary color pixel circuit 101 are sub-pixels in the same light-emitting pixel, and the two red micro-LEDs of the red-red primary color pixel circuit 101 are sub-pixels in different light-emitting pixels; the two red micro-LEDs of the red-red primary color pixel circuit 101 are respectively arranged into the corresponding light-emitting pixel area by extending the lead, so that each light-emitting pixel emits light uniformly. Figure 4 In the figure, the colors of each primary color micro-LED 105 have been marked, and 401 and 402 respectively represent one light-emitting pixel.

[0036] It should be noted that compared with the first specific embodiment, the color arrangement of the three primary color micro-LEDs 105 of each light-emitting pixel in the second specific embodiment is the same, the light emission is more uniform, and the final imaging quality is higher.

[0037] In the third specific embodiment, as shown in Figure 5 , the primary color pixel circuit 101 includes a red-red primary color pixel circuit 101, a green-green primary color pixel circuit 101, and a blue-blue primary color pixel circuit 101, the two primary color micro-LEDs 105 of the red-red primary color pixel circuit 101 are both red micro-LEDs, the two primary color micro-LEDs 105 of the green-green primary color pixel circuit 101 are both green micro-LEDs, and the two primary color micro-LEDs 105 of the blue-blue primary color pixel circuit 101 are both blue micro-LEDs; each primary color pixel circuit 101 is arranged uniformly, so that each light-emitting pixel emits light uniformly.

[0038] It should be noted that the third specific embodiment can realize uniform and sequential arrangement without extending the lead, improve light emission uniformity, and improve imaging quality. The primary color micro-LEDs 105 of the same color belong to the same material, and the photoelectric properties are consistent, the turn-on voltage is consistent, the driving voltage flip is convenient, and it is more single-driven.

[0039] In the fourth specific embodiment, as shown in Figure 6As shown, the primary color micro light emitting diode 105 also includes a white micro light emitting diode, the primary color pixel circuit 101 includes a blue-green primary color pixel circuit 101 and a red-white primary color pixel circuit 101, the two primary color micro light emitting diodes 105 of the blue-green primary color pixel circuit 101 are a blue micro light emitting diode and a green micro light emitting diode respectively, the two primary color micro light emitting diodes 105 of the red-white primary color pixel circuit 101 are a red micro light emitting diode and a white micro light emitting diode respectively, and adjacent blue-green primary color pixel circuits 101 and red-white primary color pixel circuits 101 constitute a light emitting pixel. Figure 6 In the figure, the color of each primary color micro light emitting diode 105 has been marked, and 601 represents a light emitting pixel.

[0040] It should be noted that the contrast of the light emitting pixel can be increased by adding a white micro light emitting diode, and the imaging quality can be improved.

[0041] Further, the blue-green primary color pixel circuit 101 and the red-white primary color pixel circuit 101 are spaced and uniformly arranged, so that the primary color micro light emitting diodes 105 in each light emitting pixel are arranged uniformly, and the light emission of each light emitting pixel is uniform.

The energy storage capacitor 106 is used to make the originally light emitting primary color micro light emitting diode 105 continue to emit light, thereby prolonging the light emitting time. The embodiment of the application can drive the two primary color micro light emitting diodes 105 with different directions of voltage by time sharing through the parallel connection of the two primary color micro light emitting diodes 105 with opposite electrodes, thereby reducing the number of column data leads 103, simplifying the structure of the driving integrated circuit, making the structure of the color Micro-LED device more lightweight or compact, and reducing the cost. The embodiment of the application also sets the energy storage capacitor 106, which charges and discharges through the energy storage capacitor 106 to make the originally light emitting primary color micro light emitting diode 105 continue to emit light, thereby prolonging the light emitting time, avoiding the problem that the time of a single Micro-LED lighting is shortened by time sharing driving, thereby affecting the light emitting imaging quality. When the primary color pixel circuit 101 of the embodiment of the application includes a blue-green primary color pixel circuit 101 and a red-red primary color pixel circuit 101, the two red micro light emitting diodes of the red-red primary color pixel circuit 101 are arranged in the corresponding light emitting pixel area through the extension lead, so that the light emission of each light emitting pixel is uniform, and the light emission quality is further improved.

[0043] The primary color pixel circuit 101 of the embodiment of the present application can include a red-red primary color pixel circuit 101, a green-green primary color pixel circuit 101, and a blue-blue primary color pixel circuit 101, which are more easily arranged uniformly and emit light uniformly.
