Abstract

The invention discloses an ultrathin luminous logo used for a flat panel television. The ultrathin luminous logo is mainly formed by a semitransparent or transparent logo layer, a transparent bonding layer and a backlight, wherein the semitransparent or transparent logo layer is attached to the surface of the backlight through the transparent bonding layer; the backlight comprises a light guide plate, an LED (Light Emitting Diode) lamp and a PCB (Printed Circuit Board); the LED lamp is arranged on the PCB board; the LED lamp is in contact with one end face of the light guide plate, and the end face is a light surface; one face of the light guide plate, which is close to the transparent bonding layer, is a light guide surface, and the other face is a smooth surface; the light guide surface is vertical to the light surface; a plurality of light guide points are tightly arranged on the light guide surface; a distance between the two adjacent light guide points is 0.001 mm. A production method for the ultrathin luminous logo mainly comprises the following steps of producing the semitransparent or transparent logo layer, producing the backlight, producing a reflecting material layer and assembling. The ultrathin luminous logo has the beneficial effects of thinner thickness and uniform luminescence.

Description

technical field [0001] The invention relates to the technical field of flat-panel televisions, in particular to an ultra-thin light-emitting logo used in flat-panel televisions and a manufacturing method thereof. Background technique [0002] In recent years, the logo, as the embodiment of a company's image, is the medium for the comprehensive information transmission of the enterprise. Flat-panel TVs are developing in the direction of large size and narrow borders. The space that can carry the logo is getting smaller and smaller, and the logo is getting smaller It is not obvious, how to make the logo more eye-catching and in line with the development direction of flat-panel TVs is worth thinking about. [0003] The traditional luminous logo is to form a light guide plate by printing after injection molding, and then assemble a translucent logo on the front of the light guide plate to make a luminous logo. The thinnest light guide plate in this process can be 0.6mm, plus the...
