Embodiment
Reach for further setting forth the present invention technological means and the effect that predetermined goal of the invention is taked, below in conjunction with accompanying drawing and preferred embodiment, to the optical touch control apparatus of foundation the present invention proposition and embodiment, structure, feature and the effect of display module and light source assembly thereof, be described in detail as follows.
Fig. 2 is the schematic top plan view of the optical touch control apparatus of one embodiment of the invention.Please refer to Fig. 2, the optical touch control apparatus 200 of the present embodiment comprises sensing area 230, light source assembly 220 and optical sensing subassembly 210, wherein light source assembly 220 is disposed at by the side of sensing area 230, and optical sensing subassembly 210 is positioned at the position that whole sensing area 230 is contained in its sensing visual field.Light source assembly 220 comprises a plurality of pointolites 221, and these pointolites 221 are suitable for providing the first light beam (not shown) in sensing area 230 according to sequential, and optical sensing subassembly 210 is suitable for sensing the first light beam.First light beam of the present embodiment is for example invisible light.Described invisible light is for example infrared light, that is pointolite 221 is for example the infrared light light emitting diode.
In the present embodiment, sensing area 230 is for example rectangular, and have first side 231, second side 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 light source assembly 220 for example is disposed at 231 sides, first side of sensing area 230.In addition, for being suitable for aforesaid the first light beam of sensing, optical sensing subassembly 210 can be arranged at first and survey relative corner, limit 231, for example is disposed at the intersection of the 3rd side 233 and four side 234.
In addition, light source assembly 220 more can comprise support plate 223 except comprising pointolite 221, and pointolite 221 is disposed on support plate 223, but the present invention not qualified point light source 221 must be arranged on support plate 223.In the present embodiment, these pointolites 221 are spaced, because the user normally controls with finger, so the space D that pointolite 221 is arranged is for example to be slightly less than general finger width.User's finger width is about 12 millimeters, and space D can be designed to less than 12 millimeters, as 10 millimeters, to promote the sensing precision.
Optical touch control apparatus 200 more can comprise light source control unit 260, and it is electrically connected to pointolite 221, according to the scheduled timing switch, makes pointolite 221 sequentially provide the first light beam to sensing area 230 with reference mark light source 221.In the present embodiment, light source control unit 260 is to be electrically connected to pointolite 221 through support plate 223.Yet in not coming the embodiment of bearing point light source 221 by support plate 223, light source control unit 260 can see through many signal line and be electrically connected to respectively these pointolites 221.In addition, the each luminous time of every bit light source 221 approximately continues 0.1 millisecond (ms) between 1 millisecond, but not as limit.。In addition, optical touch control apparatus 200 more can comprise substrate 240, and sensing area 230 is for example to be positioned on the surface of substrate 240, and optical sensing subassembly 210, light source assembly 220 and light source control unit 260 are for example to be disposed on substrate 240.
