Problems solved by technology

[0005] However, the existing two backlight input devices each have their application limitations
In order to ensure that the pattern 17 does not appear when the backlight module 12 is not turned on in the existing backlight input device 1, the pattern 17 must be printed with light-transmitting black ink with a shading rate of 98%, so that the utilization rate of the backlight is only 2%. The LED light-emitting diode light source 13 can make the backlight module 12 have enough light to penetrate the mylar sheet 19 to present the pattern 17 when the backlight module 12 is turned on, which improves the cost of use
In addition, the shading method of the existing backlight input device 1 and the existing backlight input device 2 is to arrange a mylar sheet 19 or a surface layer 29 above the light guide plates 14, 24, and coat the surface with screen printing. Cloth light-shielding material, the screen printing process required by this method is 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, which may shorten the service life of the backlight input device

Embodiment Construction

[0031] In view of the defects of the prior art, the present invention provides an input device with a luminous pattern. see image 3 , which is a side view of the first preferred embodiment of the input device with light-emitting patterns of the present invention. The input device 3 with luminous patterns includes an input interface 31 and a backlight module 32 . The backlight module 32 includes a light source 33 and a light guide plate 34 . The light guide plate 34 has an upper surface 35 and a lower surface 36 , and at least one pattern 37 is formed on the lower surface 36 of the light guide plate 34 . image 3 Several patterns are shown in the examples. The pattern 37 can be, for example, a pattern of a function key (such as a pattern of a power key), or a pattern of a standard keyboard, or a pattern of an interactive component of an operating system of an input device (such as a pattern of an application program displayed on a desktop). Preferably, the input device 3 o...

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 lower surface of 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. The light guide plate 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. Wherein, the touch input device has a backlight module, when the backlight module is turned on, the touch input device displays a preset pattern and provides the first input mode; when the backlight module is not turned on, the pattern is not displayed, and the second input mode is provided model. That is to say, the user can know which input mode is currently in by 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 the mode of controlling the mouse cursor. When the user sees the appearance state of the whole surface of ...
