The invention relates to a device for detecting electromagnetic radiation, said device comprising at least one row of photoresistors (45), each photoresistor comprising an active portion comprising organic semiconductor materials.

The electronic device detects a pointing input to an edge area in a viewable screen portion on one side of a display screen of a display module, provides an affordance for changing a size of the viewable screen portion based on one or a combination of two or more of a time when a pointing input is maintained in the edge area, a moving distance of the pointing input, and a moving speed of the pointing input, and changes an area of the viewable screen portion to a size determined by the pointing input through a variable driver.

A light emission device is used for a casing of the game device. This light emission device comprises a light source disposed in the casing, and a light guiding member having a plate-like shape, the light guiding member being configured to guide light emitted from the light source and being attached to the casing. The light guiding member comprises a reflecting unit configured to reflect the light incident from a first direction along a thickness direction of the light guiding member to a direction different from the first direction to diffuse the light in the interior of the light guiding member; and a light emission part configured to transmit the light reflected from the reflecting unit to outside from a surface of the light guiding member.

A lighting apparatus with an image-projecting function that is convenient for a user is provided. It includes: an illuminating unit that emits illumination light; a projection-type image display unit that emits image-projecting emission light for projecting an image; and a sensor that emits operation-detecting light for operation detection and that is capable of detecting an operation by an operation object in a range including an image projection area of the projection-type image display unit, and is configured so that the image-projecting light, and the operation-detecting emission light have respective different wavelength distribution characteristics, and regarding a light amount in the wavelength range of light used by the sensor for the operation detection, a light amount of the operation-detecting light is the largest among those of the illumination light, the image-projecting emission light, and the operation-detecting light.

A touch system is described having a method of determining touch of one or more objects on a touch surface of a touch-sensitive apparatus, wherein the method operates in a time sequence of frames, each frame comprising the steps of: for a current frame, processing an output signal of the touch sensitive apparatus to generate one or more touch traces, each touch trace having one or more characteristics; and outputting a confirmed touch signal for each touch trace having a touch trace matching at least one of said one or more characteristics in a first number of frames preceding the current frame, wherein the first number of frames is determined in dependence on said one or more characteristics.

A mobile device includes a housing, a display unit installed in the housing, wherein the display unit includes a panel which has a display panel to display a menu image and a touch panel to receive a touch input from a user, the panel having a first portion and a second portion with a transparency condition, and a sensing unit installed in the housing and disposed at a bottom of the panel to receive a user input through the panel, wherein the sensing unit includes a camera disposed to correspond to the second portion of the panel and to photograph a user through the second portion of the panel, and a sensing element to sense an object through the panel.

A method for controlling unlocking is provided. The method includes the following operations. A touch operation of a finger of user on a fingerprint recognition sensor of a terminal is detected. A first fingerprint image is received according to a preset capacity auto control (CAC) parameter corresponding to a default finger, the finger of the user is in the steady state. N second fingerprint images are received according to N sets of CAC parameters; N is an integer greater than 1. A target fingerprint image is determined and matched. The terminal is unlocked when the target fingerprint image is matched.
