Problems solved by technology

Although this driving method is more general, the low-power signal output by the control chip often cannot directly drive the LED, and power amplification is required in the middle.
These power amplifier circuits will significantly increase the design complexity of the drive circuit
Especially for μLEDs, complex driving circuits are not conducive to the construction of highly integrated systems

Abstract

The invention relates to a full-color triode light-emitting tube display device and a manufacturing method. The full-color triode light-emitting tube display device comprises a buffer layer, a first semiconductor layer arranged on the buffer layer, a first contact electrode arranged on the first semiconductor layer, an R unit used for displaying red light, a G unit used for displaying green lightand a B unit used for displaying blue light, wherein a low-power variable input signal is applied between the first contact electrode and a second contact electrode in the R unit, the G unit and the Bunit respectively, and a forward bias voltage is applied between the first contact electrode and a third contact electrode in the R unit, the G unit and the B unit respectively, so that the R unit, the G unit and the B unit are enabled to emit light. According to the invention, the light-emitting chip can be driven to emit light by using a low-power input signal to excite a color conversion layer, so that full-color display is realized.

Description

technical field [0001] The invention relates to the technical field of semiconductor display light-emitting device design, in particular to a full-color triode light-emitting tube display device and a manufacturing method. Background technique [0002] Light-emitting diodes (LEDs) are increasingly used in display applications due to their long life, small size, low power consumption, high brightness, and fast response. The micro light-emitting diode (μLED) derived from it refers to the miniaturization of traditional LEDs to form LED arrays with micron-scale spacing to achieve ultra-high-density pixel resolution. It can be widely used in flexible, transparent displays, AR, VR and other fields. It is the most One of the most promising next-generation display devices. Compared with OLED and LCD displays, μLED display colors are easier to adjust accurately, with long luminous life and high brightness. Unit display device. [0003] Although there are many advantages, for LED o...
