Problems solved by technology

The screen printing process required to coat the light-shielding substance is more complicated, which increases the manufacturing cost
In addition, the coated light-shielding substance is located on the surface of the mylar sheet 19 or the surface layer 29, which is easy to wear and fall off with time or during transportation, thereby shortening the service life of the backlight input device.

Abstract

The invention discloses an input device with a luminous pattern. The input device comprises an input interface and a backlight module. The backlight module comprises a light source and a light guide plate. The light guide plate is provided with a predetermined shading rate and forms at least one pattern at the light guide plate. When the light source is not started, the brightness of the light guide plate is lower than the predetermined shading rate and the pattern is not shown, when the light source is started, the luminous pattern is shown. A substrate of the input interface is formed by uniformly doping multiple shading particles by a transparent plastic material and jetting, and at least one pattern is formed by densely arranging micro light guide structures. According to the invention, the backlight utilization rate is improved, the cost is reduced, a process is simplified, the shading uniformity is improved, the thickness of the input device is reduced, and the long-term collision and abrasion can be avoided.

Description

technical field [0001] The present invention relates to an input device, in particular to an input device with a luminous pattern. Background technique [0002] Touch input devices are widely used. At present, some touch input devices on the market have two different input modes at the same time. The touch input device has a backlight module. When the backlight module is turned on, the touch input device displays a preset pattern to provide a first input mode. When the backlight module is not turned on, no pattern is displayed, thus providing a second input mode. That is to say, the user can determine which input mode the touch input device is currently in according to whether the pattern is displayed, and then input signals according to the mode. For example, when the backlight is not turned on, the appearance of the touch input device is completely black, and the input mode is preset to control the mouse cursor. At this time, the user can move according to the touch inpu...
