Display array for constructing two-dimension or three-dimension display apparatus

Abstract

The invention discloses a display array used for establishing a two-dimensional or three-dimensional display device. The display array comprises a plurality of linear display units, wherein, dot-shaped luminous bodies and a control circuit used for controlling the dot-shaped luminous bodies are arranged on the linear display units; the linear display units are connected with each other through a corresponding control signal line; the display array further comprises a power supply circuit which is separated from the control signal line; the power supply circuit consists of at least a positive pole power cord and a negative pole power cord which are separated from each other; and the linear display units are distributed and fixed along the power supply circuit at certain intervals, and are electrically connected with the positive pole power cord and the negative pole power cord. The separation of the power supply circuit from the control circuit solves the problem that the adoption of a printing circuit board on the prior display unit causes restriction on power supply currents, so that the display array provided by the invention can be used for manufacturing a large two-dimensional or three-dimensional device which can expanded without restriction.

Description

technical field [0001] The invention relates to a display unit that can be used to construct a display device, in particular to a display array capable of constructing a two-dimensional or three-dimensional display device. Background technique [0002] Lighting decorations, outdoor display screens, etc. have been widely used, mainly for festival decoration and advertising display. Existing products are mainly based on one-dimensional or two-dimensional display, but there are also three-dimensional display, you can refer to the inventor's related patent on three-dimensional display system, utility model patent, patent number ZL200820044456.8, the patent name is a three-dimensional display system Display system (the publication number is CN201177927, the publication date is January 07, 2009), and the invention patent, the application number is 200810026565.1, and the patent name is a three-dimensional display system and its display control method (the publication number is CN1...

AI Technical Summary

Problems solved by technology

Whether it is a one-dimensional, two-dimensional or three-dimensional display device, it is built with some display units. Generally speaking, the display unit is made of a printed circuit board. Control circuits and light emitters are distributed on the circuit board. Corresponding control lines need to be distributed to transmit control signals and power supply lines to supply power to this display unit and all illuminants in all display units below. Therefore, the display unit needs to flow a large current, but it is limited by the structure of the printed circuit board. The number of illuminants on each display unit is limited, and too many display units cannot be connected in series, which causes certain difficulties in manufacturing large-scale display devices
