Problems solved by technology

For example, in the current driving of Micro LED displays, the forward bias voltage of Micro LEDs emitting red light is about 1.8 volts, but the forward bias voltage of Micro LEDs emitting green light and blue light is about 3.7 volts. , because the driving substrate needs to provide different driving voltages for Micro LEDs with different light colors, resulting in a relatively high power consumption problem for the display

Abstract

The invention discloses a micro light-emitting diode display device which comprises a circuit substrate and a plurality of display pixels. The display pixels are configured on the circuit substrate and are electrically connected with the circuit substrate respectively, and each display pixel comprises a plurality of micro light-emitting elements; in each display pixel, a part of the micro light-emitting elements form at least one series structure, and the micro light-emitting elements in the series structure are in a wavelength range of the same emergent light color, and the circuit substrate provides the same driving voltage to drive the series structure of each display pixel and other micro light-emitting elements except the series structure.

Description

technical field [0001] The present invention relates to a display device, in particular to a micro light-emitting diode display device. Background technique [0002] When the world is paying attention to the future display technology, micro light emitting diode (Micro LED) is one of the most promising technologies. To put it simply, Micro LED is a technology that miniaturizes and matrixes LEDs. Millions or even tens of millions of grains that are smaller than 100 microns and thinner than a hair are neatly arranged on the driver substrate. Compared with the current OLED (Organic Light Emitting Diode) display technology, Micro LED displays also emit light independently, but due to the use of different materials, it can solve the most fatal "burn-in" problem in OLED displays, and at the same time have lower power consumption , high contrast, wide color gamut, high brightness, small size, light and thin, energy-saving and other advantages. Therefore, major manufacturers around...
