Problems solved by technology

[0011] 2. Pour the glue into the reflector, the glue color is very easy to mix, it is impossible to control the appearance of the glue color of each section
[0012] 3. Inject the glue into the reflection plate. It is very difficult for the glue of various colors to flow into the characters and patterns (ICON), so it will cause the problem of lack of glue in each character or pattern.
[0013] 4. General LED display products can only present one color on the code or pattern, but cannot present different colors on the code with glue color
[0014] 5. When the circuit board is placed in the reflector, the color glue is easy to overflow and mix due to extrusion

Embodiment Construction

[0026] image 3 It is a flow chart of the manufacturing method of the present invention. The present invention is a manufacturing method of a color festival display that can directly present a variety of different colors on each character code or pattern of a reflector without being lit by a chip. The display production procedure includes the following steps:

[0027] a) Paste heat-resistant tape on the product to be produced.

[0028] b) Inject color glue into each character code and pattern of the reflector in a pinhole segmented manner, and keep the temperature of the reflector at 50-60°C during glue filling, so that the color glue newly injected into the reflector It can smoothly flow into the code and pattern, and increase the consistency of the color glue that has been injected into the code and pattern, so as to avoid the mixing of the color glue due to extrusion when the white glue is injected into the reflector and the circuit board.

[0029] c) Wait for it to cool ...

Abstract

The invention discloses a process for manufacturing color display, first, color glue is injected into each character and pattern (i.e. each color section) of the reflecting plate using a pinhole section by section, and keeps the temperature of the reflecting plate between 50 to 60 degree during the glue encapsulating process, then the reflecting plate is placed into a 85 degree oven for 15 minutes to increase consistency of the color glue, waits till it gets cooled down, use centrifugal method to remove the air bubbles in the each pattern and characters, then inject white glue into the reflecting plate, place the circuit board which has undergone crystal fixing and wire welding into the reflecting plate, after roasting the finished product will be completed.

Description

technical field [0001] The invention relates to a method for manufacturing a color festival display, in particular to a method for manufacturing a display that can directly present a variety of different colors on each character code or pattern on a reflective plate without lighting up a chip. Background technique [0002] Existing light-emitting diode (LED) displays are widely used in various electrical appliances that need to display characters, numbers, and patterns. figure 1 It is the appearance diagram of the existing LED display. For the displays currently on the market, the appearance colors of the characters or patterns of the display 1a before being lit are all the same (single color), so when the power is not turned on, it cannot Know its color after lighting. [0003] figure 2 It is a flow chart of the existing LED display production program, including the following steps: [0004] a1). Paste heat-resistant tape on the product to be produced. [0005] b1). Po...
