Be described in detail to the implementation of the specific embodiment of the invention below.
The part-structure schematic diagram that Fig. 1 is Trackpad described in first embodiment of the invention.Consult Fig. 1, this Trackpad specifically comprises:
Touch control component, is arranged at the inside of apparatus casing, and by the touch operation of this touch control component induction user in touch-sensitive area, in the specific embodiment of the invention, the rectangular region in the middle of Fig. 1 constitutes touch-sensitive area 100;
Pointolite 10, is arranged at outside touch-sensitive area 100;
Light pipe 20, is connected with pointolite 10, is arranged at least one limit of touch-sensitive area 100, carrys out the light that conducting spots light source 10 sends, the light that pointolite 10 sends is conducted to the edge of touch-sensitive area 100 by this light pipe 20;
Light guide plate 30, covers and is arranged on touch-sensitive area 100, and the light conduction for being sent by light pipe 20 is the planar light at touch-sensitive area 100 place.
In the specific embodiment of the invention, as Fig. 1, pointolite 10 comprises the light emitting diode that four can convert glow color, light pipe 20 is arranged around four edges, limit of touch-sensitive area 100, be configured to frame structure, each light emitting diode is all connected to light pipe 20, the light that light emitting diode is sent can uniform conductive to the edge of touch-sensitive area 100, be line source by pointolite conduction.
In the specific embodiment of the invention, covering the light guide plate 30 be arranged on touch-sensitive area 100 is atomization plate body, makes the light of varying strength different in the conduction distance of light guide plate 30.Particularly, the side of light guide plate 30 contacts with light pipe 20 respectively and connects, the light that light pipe 20 is derived can evenly enter light guide plate 30, but along with the light intensity of each light emitting diode change, color change and the switch conditions of different light emitting diode, light guide plate 30 forms different hatching patterns, and can change, move, produce dynamic luminous efficiency.
The another kind of embodiment of Trackpad described in the specific embodiment of the invention as shown in Figure 2, wherein pointolite 10, light pipe 20 are identical with the shape of the first embodiment with light guide plate 30, but light pipe 20 and light guide plate 30 integrative-structure are arranged, make light pipe 20 and light guide plate 30 integral installation above touch control component, make light guide plate 30 just be covered on touch-sensitive area.
When light pipe 20 and light guide plate 30 integrative-structure are arranged, in order to make that light guide plate 30 also can produce dynamic luminous efficiency, multiple blind hole 31 regularly arranged can be set at the lower surface of light guide plate 30, as shown in Figure 3, by those blind holes 31, destroy the even light-guiding characteristic of optical material, light guide plate 30 is changed in the penetrability of zones of different, the light of varying strength is different in the transmission range of light guide plate 30, when the light intensity of each light emitting diode, color and switch regularly change like this, light guide plate 30 forms different hatching patterns, produces dynamic luminous efficiency.
In the Trackpad of above-mentioned two kinds of embodiments, light guide plate 30 covers as a luminous plate body and is arranged on the induction electrode layer of touch control component, and light guide plate 30 is fitted and connected with the upper surface of induction electrode layer, and size can be identical with induction electrode layer.For ensureing the touch operation sensitivity of Trackpad, best, the thickness of light guide plate 30 is less than 2mm.
