Embodiment Construction

[0018] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0019] like figure 1 As shown, the multi-BIN LED synchronous identification method of the present invention mainly comprises the following steps:

[0020] S1. Set up a row of pads on the light board corresponding to LEDs of each BIN. A row of pads includes at least three unit pads, so that the pads have enough length to set the identification code.

[0021] S2. The LEDs of various BINs are respectively provided with identification codes according to the law, and the LEDs of each BIN have a unique identification code. The identification code is compiled in binary, and one unit pad represents one character of the identification code. When the pad with solder paste represents "1" in binary, the pad without solder paste represents "0" in binary; when the pad with solder paste represents "0" in binary, then A pad without solder paste represents a "1" i...

Abstract

The invention relates to the technical field of LED display, in particular to a synchronous marking method for LEDs of multiple BINs. The method mainly includes the following steps that 1, a lamp panel is provided with a row of bonding pads corresponding to the LEDs of each BIN; 2, the LEDs of multiple BINs are correspondingly provided with identification codes according to the rule; 3, the identification codes are transferred onto the bonding pads by soldering paste on the corresponding bonding pads. According to the method, marking and lamp panel production can be synchronously conducted, and thus production efficiency is high; identification can be easily achieved, which is of great significance for subsequent detection and maintenance.

Description

technical field [0001] The invention relates to the technical field of LED display, in particular to a multi-BIN LED synchronous identification method. Background technique [0002] At present, the raw materials such as wafers used in the LED field are discrete. When the wafers are sealed into LED lamp beads, the luminous brightness and wavelength have a certain range under a certain current condition, resulting in a variety of BINs. During the production process of the display screen It is often necessary to mix LEDs of various BINs on the same light board. After the production of the light board is completed, it is difficult to identify the BIN of the LED from the appearance, which is not convenient for subsequent inspection and maintenance. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a multi-BIN LED synchronous identification method. [0004] To achieve the above object, the present...
