Abstract: A capacitive touch system includes a touch panel, a detection circuit, and a microprocessor. The touch panel includes a plurality of first axis lines of a first axis and a plurality of second axis lines of a second axis. The processor is used for controlling the detection circuit to transmit a first transmission signal to a first axis line and receive a plurality of first detection signals corresponding to the first transmission signal from the second axis lines. If a delay between a first detection signal of the plurality of first detection signals and the first transmission signal is greater than a first predetermined value, the processor controls the detection circuit to transmit a second transmission signal to a second axis line corresponding to the first detection signal, and receive a plurality of second detection signals corresponding to the second transmission signal from the plurality of first axis lines.

Abstract: A backlight module includes a light guide plate, a first light module, and a second light module. The light guide plate includes first troughs and second troughs on opposite sides. The first light module includes a first substrate and first LEDs thereon. An opaque element is disposed on each first gap between two adjacent first LEDs, each first LED is embedded in one first trough. The second light module includes a second substrate and second LEDs thereon. An opaque element is disposed on each second gap between two adjacent second LEDs, and each second LED is embedded in one second trough. Each first LED is disposed to one second gap, and each second LED is disposed in one first gap. Light from first LED is absorbed by the opaque element on the second substrate, and that from the second LED is absorbed by the opaque element on the first substrate.

Abstract: A backlight module includes a housing, at least a light-mixing tube, a plurality of light emitting devices, and at least a reflector. The housing includes a bottom sheet and a frame, in which the bottom sheet and the frame define a chamber. The frame is a hollow structure, and inner walls of the frame define the light-mixing tube. The light emitting devices are disposed at a light entrance of the light-mixing tube. Lights generated by the light emitting devices enter the light-mixing tube from the light entrance, mix in the light-mixing tube, and emit from a light exit of the light-mixing tube. Lights emit from the light-mixing tube are reflected at the reflector and therefore are reflected into the chamber.

Abstract: A side type backlight module including a first light guide plate (LGP), a plurality of second LGPs, a plurality of red point light sources, a plurality of green point light sources, and a plurality of blue point light sources is provided. The first LGP has a first light emitting surface, a bottom surface, and a first light incident surface connecting the first light exit surface and the bottom surface. The second LGPs are disposed beside the first light incident surface. Further, a plurality of red, green, and blue point light sources is respectively disposed beside the second LGPs. The lights emitted by the red point light sources, the green point light sources, and the blue point light sources are blended to be a white light by each of the second LGPs and then incident to the first light incident surface.
