A key structure having an improved light emitting efficiency is provided. The key structure includes a light guide plate, an isolation sheet, a circuit board, an elastic member, and a key cap sequentially disposed one on another in order. A circuit and a plurality of first electrical contacts are distributed on a top surface of the light guide plate. An optical structure is disposed at a bottom surface of the light guide plate. The isolation sheet has a light reflective surface facing the light guide plate. A light source emits a light into the light guide plate. The light is reflected by the optical structure to pass through the through holes configured at the isolation sheet, thus allowing more light outputting through the through holes, so as to improve the illumination of the key cap, and improve the light emitting efficiency.

A display is disclosed. The display comprises a panel, a data driver and a scan driver. The panel comprises pixels, data lines and scan lines. The data lines transmit data signals to the pixels, and the scan lines transmit scan signals to the pixels. The data driver provides the data signals, and the scan driver provides the scan signals. The scan driver comprises a shift register circuit. The shift register circuit comprises an i+1th stage carry shift register, an ith stage carry shift register and a jth stage buffer shift register. The ith stage carry shift register generates an i+1th start signal to start the i+1th stage carry shift register, so that the i+1th stage carry shift register generates an i+2th start signal. The i+1th start signal starts the jth stage buffer shift register to generate a jth output signal.

A keyboard device includes at least an illuminant element, at least a pressing key element and a light guide element. The pressing key element includes a keycap reciprocating along a first axial direction when being pressed and a recovering component attached to the keycap for supporting and pushing back the keycap when not pressed. The light guide element is located at one side of the recovering component. The light guide element includes at least a light-incident part and a light-emitting part. The light-incident part is used for receiving light emitted from the illuminant element. The light-emitting part emits light along a second axial direction to the recovering component so that the recovering components guide light to the keycap, wherein the second axial direction is different to the first axial direction.

A method and a structure for improving the uniformity of light emitted from a backlight module are provided. In accordance with the present invention, a plurality of optical microstructures are intermittently distributed on an LGP of a backlight module. Each of the microstructures further includes a plurality of optical sub-microstructures. The optical microstructures and the optical sub-microstructures are distributed on the LGP with varied distribution intensities in three dimensions, such that at where the optical microstructures and the optical sub-microstructures are distributed with a larger distribution intensities the LGP refracts and reflects more light, and at where the optical microstructures and the optical sub-microstructures are distributed with a smaller distribution intensities the LGP refracts and reflects less light. In such a way, by designing particular distribution intensities of the optical microstructures and the optical sub-microstructures, the light emitted from the LGP can be uniformed.

摘要:
A double-sided light-emitting light guide plate assembly, and a method for manufacturing the same are disclosed, wherein a reflector is arranged between a first light guide plate and a second light guide plate. When light is emitted from a light source, it enters into the first light guide plate and the second light guide plate from one lateral side of the double-sided light-emitting light guide plate assembly. Through the reflector having two opposite reflective surface, the light is output from the first light output surface of the first light guide plate, and the second light output surface of the second light guide plate, such that the light guide plate assembly of the present invention can emit light from its two opposite surfaces.
