Abstract

The invention discloses a linear array and digital combined light-emitting diode (LED) display process. The process comprises the following steps of: 1), uniformly depositing a thick film paste to a ceramic substrate by virtue of holes of a silk screen on a mask plate to form a pattern having certain thickness and shape; 2), adhering an LED linear array, a nixie tube and a decoder to the ceramic substrate by a conductive adhering agent to form a device paster area in the pattern; and melting a gold wire end with a semiconductor chip welding area conductor, a gold wire end head and a thickness film conductive belt; 3), adhering a ceramic cover with a view window to the ceramic substrate by an insulated adhesive tape, and packaging the LED linear array, the nixie tube and the decoder; and 4), inserting a wire at two ends on the same surface of the enclosed display device to form two columns of outer wires, and performing tin soaking on the outer wires. An LED display circuit has a simple structure, and is simple in process, easy to control, test and rework, high in processing efficiency of the process, low in processing and material costs.

Description

technical field [0001] The invention relates to a manufacturing process of an LED display, a manufacturing process of a linear array and a digital combination LED display. Background technique [0002] LED display technology is widely used in the aiming environment of various remote control systems. It can automatically display the accurate position (point), graphics, symbols, numbers, etc. of the target under wide-area light environments such as white light, dim light, and infrared. [0003] At present, LED display technology is dominated by integrated area array display technology, and its shortcomings are: [0004] 1) Software programming is complex; [0005] 2) The middle test of the LED area array is complex and difficult to rework and repair; [0006] 3) The LED area array processing process has a large workload, and the cost of materials and process control is high. Contents of the invention [0007] The technical problem to be solved by the present invention is ...
