Fig. 2 is the schematic top plan view of the optical touch control apparatus of one embodiment of the invention.Refer to Fig. 2, the optical touch control apparatus 200 of the present embodiment includes sensing area 230, light source assembly 220 and optical sensing subassembly 210, wherein light source assembly 220 is configured at by the side of sensing area 230, and optical sensing subassembly 210 is positioned at its sensing visual field and contains the position of whole sensing area 230.Light source assembly 220 includes multiple point source 221, and these point sources 221 are suitable to provide the first light beam (not shown) in sensing area 230 according to sequential, and optical sensing subassembly 210 is then suitable to sense the first light beam.The first light beam e.g. black light of the present embodiment.Described black light e.g. infrared light, that is, point source 221 for example, infrared light emitting diodes.
Optical sensing subassembly 210 is e.g. arranged on above sensing area 230, the optical signal (the i.e. first light beam) provided with detected light source component 220.Light source assembly 220 can be located at above sense lateral areas 230, to provide the optical signal that can be directly entered sensing area 230.In another embodiment, sensing area 230 can be located at above light guide plate (not shown), and light source assembly 220 is in by light guide plate, and the optical signal that light source assembly 220 is provided imports sensing area 230 via light guide plate.
In the present embodiment, sensing area 230 is the most rectangular, and there is first side 231, second side the 232, the 3rd side 233 and four side 234, wherein first side 231 is relative with the 3rd side 233, second side 232 is relative with four side 234, and the first side 231 that light source assembly 220 is such as configured at sensing area 230 is other.Additionally, for being suitable to sense aforesaid first light beam, optical sensing subassembly 210 may be disposed at surveys, with first, the corner that limit 231 is relative, such as be configured at the 3rd side 233 and the intersection of four side 234.
It addition, light source assembly 220 is in addition to comprising point source 221, more can include support plate 223, and point source 221 is configured on support plate 223, but the present invention does not limit point source 221 and must be provided with on support plate 223.In the present embodiment, these point sources 221 are spaced, owing to user is typically to manipulate with finger, so the space D of point source 221 arrangement is e.g. slightly less than general finger width.The finger width of user is about 12 millimeters, and space D may be designed to less than 12 millimeters, such as 10 millimeters, to promote sensing precision.
Optical touch control apparatus 200 more can include light source control unit 260, and it is electrically connected to point source 221, switchs according to scheduled timing with control point light source 221, makes point source 221 be sequentially provided the first light beam in sensing area 230.In the present embodiment, light source control unit 260 is to be electrically connected to point source 221 through support plate 223.But, in the embodiment not carrying out bearing point light source 221 by support plate 223, light source control unit 260 can pass through a plurality of signal line and is respectively and electrically connected to these point sources 221.Additionally, every bit light source 221 the most luminous time last about greatly 0.1 millisecond (ms) between 1 millisecond, but be not limited.It addition, optical touch control apparatus 200 more can comprise substrate 240, and sensing area 230 is e.g. positioned on the surface of substrate 240, and optical sensing subassembly 210, light source assembly 220 and light source control unit 260 are e.g. configured on substrate 240.
