Abstract

The invention discloses a micro light emitting diode display device. The micro light emitting diode display device comprises a display panel and a driving circuit, the display panel comprises a plurality of pixel group units arranged side by side in a first direction, and each pixel group unit is provided with a plurality of pixels in an extending mode in a second direction. The driving circuit outputs a first voltage and a second voltage and transmits the first voltage and the second voltage to the pixels of each pixel group unit of the display panel; the display panel is provided with a first side edge and a second side edge which are opposite to each other in the second direction, the first voltage is led into the display panel from the first side edge, the second voltage is led into the display panel from the second side edge, and the voltage difference between the first voltage and the second voltage is positively related to the brightness of one connected pixel.

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 smaller than 100 microns and thinner than a hair are neatly arranged on the substrate. Compared with the current OLED (Organic Light Emitting Diode) display technology, Micro LED also emits light independently, but due to the use of different materials, it can solve the most fatal "burn-in" problem of OLED, and also has low power consumption, high contrast, Wide color gamut, high brightness, small size, light and thin, energy-saving and other advantages. Therefore, major manufacturers around the world are rushing to invest in the research ...
