Abstract

The invention discloses a micro light emitting diode display system. The micro light emitting diode display system comprises a host, a plurality of row / column drivers and a plurality of micro light emitting diode integrated circuits. The plurality of row / column drivers are respectively coupled to the host through a sequence interface and are used for respectively providing a plurality of row clock signals and a plurality of column data signals. The plurality of micro light emitting diode integrated circuits are arranged in a matrix, and the matrix comprises a plurality of columns of micro light emitting diode integrated circuits and a plurality of rows of micro light emitting diode integrated circuits which are respectively used for receiving the plurality of column data signals and the plurality of row clock pulse signals. All the micro light-emitting diode integrated circuits in the same column of micro light-emitting diode integrated circuits are sequentially connected in series, and all the micro light-emitting diode integrated circuits in the same row of micro light-emitting diode integrated circuits are sequentially connected in series.

Description

technical field [0001] The invention relates to a display device, in particular to a micro light emitting diode display system. Background technique [0002] Such as Figure 1A and Figure 1B As shown, a traditional micro-light-emitting diode display system 1 includes a host 10, a first row / column driver 121 to a k-th row / column driver 12k, and (k*m*n) micro-light-emitting diode integrated circuits μIC, where k, m , n are both positive integers. [0003] The host 10 is respectively coupled to the first row / column driver 121 to the kth row / column driver 12k through a serial interface. The (k*m*n) micro light emitting diode integrated circuits μIC are arranged in the form of k (m*n) matrix. The first row / column driver 121 to the kth row / column driver 12k are used to respectively couple and drive the k (m*n) micro light-emitting diode integrated circuits μIC arranged in a matrix. [0004] Taking the first row / column driver 121 as an example, the first row / column driver 121 ...
