The present disclosure provides a backlight module, including a substrate, a plurality of light-emitting elements, a protective layer and a plurality of first dots. These light-emitting elements are disposed on the substrate. The protective layer is disposed on the substrate and the light-emitting elements, the protective layer has an upper surface and a lower surface opposite to the upper surface, and the upper surface of the protective layer is flat. The first dots are disposed on the upper surface of the protective layer and cover the light-emitting elements. A vertical projection area of each of the first dots on the substrate is larger than a vertical projection area of each of the light-emitting elements on the substrate, so as to reduce the thickness of the backlight module and reduce the dots alignment process.

An electronic device includes a substrate film having a first side and a second side, and a number of light sources configured to emit light. A plastic lightguide layer is molded onto the first side of the substrate film. The plastic lightguide layer being of optically at least translucent material to transmit light. The device also includes a masking layer provided on the outer surface of the plastic lightguide layer. The masking layer defines a window for letting the light emitted by the embedded light sources to pass through the masking layer towards the environment.

A bio-sensor device, integrated with a display portion, includes a surface for touching by a body part, such as a finger. A light source, such as an array of LEDs, emit light through the surface so as to be reflected and partially absorbed by the body part An array of photodetectors detects light reflected back by the body part and generates signals corresponding to an image of the light reflection, which corresponds to the light absorption pattern in the body part. The light absorption pattern may correlate to a fingerprint, a blood vessel pattern, blood movement within the blood vessels, combinations thereof, or other biometric feature. A processor receives the signals from the photodetectors and analyzes the signals to determine a characteristic of the body part. The characteristic may be used to authenticate the user of the bio-sensor device by comparing the detected characteristic to a stored characteristic.

A backlight module comprising an optical component, a frame and an elastic member is presented. The frame has a first sidewall and a second sidewall. An end of the first sidewall is connected to an end of the second sidewall to form a corner portion. The first sidewall and the second sidewall are located at different sides of the optical component. The first sidewall and the second sidewall include a first angle therebetween. The elastic member is configured to be disposed on the frame. The elastic member includes a flange portion, a first extension portion and a second extension portion. The flange portion is configured to be disposed on the corner portion. The first extension portion extends along a first direction away from the flange portion and has a first surface. The second extension portion extends along a second direction away from the flange portion and has a second surface. A second angle is included between the first extension portion and the second extension portion. Wherein before the elastic member is disposed on the frame, the second angle is greater than the first angle; when the elastic member is disposed on the frame, the flange portion engages with the corner portion, the first surface is against an inner surface of the first sidewall, and the second surface is against an inner surface of the second sidewall.

Disclosed are a display device and a backlight module. The display device includes a backlight module, a liquid crystal display panel, and a chip-on-flex. The backlight module may include a frame body, and an edge-type light source, a light guide plate, a reflector strip, a light absorber strip, and an optical film disposed in the frame body. The light absorber strip and the diffuser sheet are not bonded, and the reflector strip and the diffuser sheet of the optical film are bonded.

The present invention provides a clamper and a lighting fixture. An elastic layer for contacting a panel is disposed on a rotatable clamping portion. In addition to that, a distance from a lowest point of one end of the panel clamped by the rotatable clamping portion to a carrier plate supporting a polarizer at one side of the panel adjacent to a thin film transistor is greater than a thickness of the polarizer. Accordingly, the present invention prevents the panel and the polarizer at one side of the panel adjacent to the thin film transistor from being damaged from clamping.

A light guide module suitable for being disposed on a reflective display panel includes a light guide plate and a light-shielding part. The light guide plate has a first surface, a second surface opposite to the first surface, and an optical structure formed in the first surface. The first surface has a display area and an edge area surrounding the display area, and the optical structure is distributed in the display area. The light-shielding part is disposed on the first surface and covers the edge area, in which the light-shielding part has an opening exposing the display area.

A light guiding column is with a waterproofing function and for guiding light emitted from a light emitting component to outside of a case. The light emitting component is disposed on a base plate. The base plate is disposed inside the case. The light guiding column includes a first end portion and a second end portion. The first end portion passes through a through hole formed on the case in a tight-fitting manner. The second end portion is opposite to the first end portion and clamped between the base plate and the case in a tight-fitting manner. A chamber is formed between the second end portion and the base plate, and the light emitting component is accommodated inside the chamber. The present invention can reduce an amount of components for assembly to reduce manufacturing cost and difficulty in assembly.
