Ultrathin interactive logo for household electrical appliance and manufacturing method for same

Abstract

The invention discloses an ultrathin interactive logo for a household electrical appliance. The logo comprises a semitransparent or transparent logo layer, and multiple letters are displayed on the surface of the semitransparent or transparent logo layer. A protection film layer is arranged on one side of the semitransparent or transparent logo layer, and a transparent bonding layer is arranged on the other side of the semitransparent or transparent logo layer. The semitransparent or transparent logo layer bonds with a backlight layer through the transparent bonding layer. The backlight layer is mainly composed of backlight units, a reflection material layer and a flexible circuit board. The number of the backlight units is equal to the number of the letters, and the backlight units and the letters are arranged in one-to-one correspondence. Each backlight unit is composed of a light guide plate and an LED lamp, the LED lamp is mounted on the flexible circuit board, the end surface of one end of the light guide plate is in contact with the LED lamp, the end surface serves as the light incoming surface, the front surface of the light guide plate serves as the light outgoing surface, and the back surface of the light guide plate is connected to the reflection material layer. A manufacturing method for the logo comprises steps of manufacturing the semitransparent or transparent logo layer, manufacturing the backlight layer, manufacturing the reflection material layer, and assembling the layers. The beneficial effects of the logo are that the logo is uniform in luminescence and is thin in thickness.

Description

technical field [0001] The invention relates to the technical field of home appliances, in particular to an ultra-thin interactive logo used in home appliances and a manufacturing method thereof. Background technique [0002] In recent years, electronic products are developing in the direction of large size and ultra-thin. Logo is the embodiment of a company image. More and more users pay more attention to the interaction between individuals and products. Interactive logo will become a product brand image. At the same time, it can satisfy the user to make corresponding feedback during operation. [0003] The traditional luminous logo is to use injection molding or cutting PMMA sheet to print to form a light guide plate, and then assemble a translucent logo on the front of the light guide plate to make a luminous logo. The thickness of the material is difficult to achieve ultra-thin, and injection molding requires an injection mold, which increases the cost of injection mold...

AI Technical Summary

Problems solved by technology

[0004] The invention overcomes the disadvantages of using LED lamps to directly emit light on the back of the translucent logo in the prior art, such as uneven luminescence, high cost of using too many LED lamps, etc., and provides a method that can realize individual luminescence of each letter, and can emit light evenly Ultra-thin interactive logo for home appliances that achieve luminous brightness
