Description

Technical Field

[0001] The present invention relates to the technical field of MINILED for washing machines, and in particular to a production process and application of MINILED for matrix direct display washing machines. Background Art

[0002] With the rise and maturity of organic light-emitting diode (OLED) technology, OLED products have gradually become the new favorite in the market;

[0003] Most washing machines currently on the market use TFT screens to display icons, time and other information. After a long period of use, vibrations can damage the TFT screen, resulting in a relatively high failure rate. Most washing machines are placed on balconies, where sunlight can cause the TFT screen to reflect light and become unclear. MINILED direct display takes advantage of its high brightness and high definition, providing a clear and concise display during the day. In addition, the display may freeze, while the MINILED direct display has a short response time and strong reliability. The original solution was to combine a TFT screen with a main control board to form a display module. This solution was too thick and might not meet usage scenarios with thickness requirements. The MINILED direct display technology can integrate the light driver and washing machine control circuit on the PCB, integrating all functions on one PCB, greatly reducing the thickness. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems of the above-mentioned background technology and to propose a production process and application of MINILED for matrix direct display washing machine.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] An application of a MINILED matrix direct display washing machine, comprising:

[0007] MINILED is used in household washing machines. It uses integrated row and column channel wiring to individually control each lamp bead on the display panel, allowing each lamp bead to be used as an independent pixel.

[0008] The washing machine display panel uses six hexadecimal digits 0x000000-0xffffff to establish color coordinates. The host computer defines the color coordinates for each pixel, and the MCU parses the defined instructions to control the array to form a complete RGB single image. A page-turning relationship is established between each image, with active or passive triggering.

[0009] Among them, MINILED uses an array arrangement of 128*72 lamp beads.

[0010] A production process for a matrix direct display MINILED washing machine, comprising the following steps:

[0011] Step 1: Transfer a large amount of MINILEDs onto a PCB coated with solder paste, and then place the bonded PCB into a baking tunnel;

[0012] Step 2: After the temperature rises, the solder paste melts and the MINILED is fixed on the PCB, thus obtaining the matrix direct display MINILED;

[0013] Among them, the PCB baking steps are:

[0014] Step 11: Start the rotary motor to drive the turntable to rotate. Through the annular groove, the connecting plate moves back and forth along the support plate. The limit shaft of the connecting plate away from the turntable will act on the movable plate, causing the movable plate to rotate along the frame. The movable block on the top of the movable plate will act on the second groove of the driving plate, causing the support plate on the curing plate to work back and forth in a curve, which will drive the PCB board to move forward along the conveyor belt interval.

[0015] Step 12: The curing plate is set up so that the heat source heats and cures the PCB board.

[0016] As a further solution of the present invention: the size ratio of the MINILED to the PCB is 0.8:1.

[0017] As a further solution of the present invention: the thickness of the solder paste is 0.03 mm.

[0018] As a further solution of the present invention: the annular groove is an elliptical structure.

[0019] As a further solution of the present invention: a plurality of curing plates are arranged at equal intervals on the top surface of the driving plate.

[0020] As a further solution of the present invention: a plurality of air outlets are evenly arranged on the surface of the curing plate.

[0021] As a further solution of the present invention: hot air pipes are respectively connected to both sides of the bottom surface of the curing plate.

[0022] As a further solution of the present invention: supporting plates are provided on both sides of the top surface of the curing plate.

[0023] Beneficial effects of the present invention:

[0024] (1) The matrix direct display MINILED prepared by the present invention has the advantages of high brightness, high contrast, high definition, strong reliability, fast response time, and greater energy saving, and the display control module is thin;

[0025] (2) The present invention provides a curing device that can not only intermittently load the PCB board, but also improve the loading channel into a baking channel during the loading process to continuously cure and mold the PCB board, thereby improving the efficiency of MINILED molding.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0036] Example 1

[0037] See also Figure 1 As shown, the present invention is an application of a MINILED for a matrix direct display washing machine, including the following contents:

[0038] MINILED direct display technology is applied to household washing machines, using a 128*72 LED array to achieve a high-density pixel display effect. Using row and column channel integrated wiring technology, each LED on the display panel can be individually controlled, allowing each LED to function as an independent pixel.

[0039] The software driver enables complete UI customization of the washing machine's display panel. Six hexadecimal numbers (0x000000-0xffffff) are used to establish color coordinates, enabling controllable display of the visible light color gamut. The host computer software defines the color coordinates for each pixel, and the MCU interprets these instructions, controlling the array to form a complete RGB single image. Actively or passively triggered page-turning relationships are established between each image, creating a freely variable dynamic effect that overcomes the limitations of the color filter pattern.

[0043] Step 2: After a specific temperature rise, the solder paste is melted and the MINILED is fixed on the PCB; thus, a matrix direct display MINILED is obtained; the lamp driver behind the PCB controls the brightness of the MINILED through the row and column channels to achieve the effect of displaying patterns.

[0044] The matrix direct display MINILED prepared by the present invention has the advantages of high brightness, high contrast, high definition, strong reliability, fast response time, and greater energy saving of MINILED, and the display control module is thin.
