A gas light source is disclosed where gas is contained within a graphene cylinder or graphene capsule. Electrodes extending into the graphene cylinder or capsule are stimulated by an electric voltage to emit light. Eight graphene cylinder light sources can be arranged into a seven-segment alpha-numeric display having a decimal point. Different gases produce different colors of light. Three gas light sources having different gases can be arranged into an RGB pixel. An array of RGB pixels can be formed into a display.

A method includes receiving a face image and lens measurements of a person, and selecting a three dimensional (3-D) model of a frame of a pair of smart glasses from a plurality of 3-D models of frames for placement on the face image of the person. The pair of smart glasses includes a virtual display embedded in, or overlaid on a lens. The method further includes sizing the selected 3-D model of the frame of the pair of smart glasses for placement on the face image of person based on the lens measurements of the person, and determining a gazability of the virtual display in the 3-D model of the pair of smart glasses placed on the face image of the person.

A gate driver IC (i.e., gate driver circuit), when set to a first mode by a logic signal of the terminal FNC*, shifts data in the gate driver IC in synchronization with one clock cycle of a clock inputted to the terminal CLK** (clock input terminal), and outputs a selection voltage or a non-selection voltage based on a data position in the gate driver IC; and when set to a second mode by a logic signal of the terminal FNC*, shifts data in the gate driver IC in synchronization with n clock cycles (n is an integer of at least 2) of a clock inputted to the terminal CLK**, and outputs the selection voltage or the non-selection voltage based on the data position in the gate driver IC.

A temperature sensor arrangement includes a current integrating modulator that provides a count value dependent on the current supplied to its input terminal. A temperature-sensitive element includes a resistor to generate a current dependent on temperature. First and second switches alternately connect the temperature-sensitive element and another resistor to the input terminal of the current integrating modulator. The temperature sensor arrangement can be combined with an ambient light sensor sharing the current integrating modulator.

A light emitting diode (LED) failure detecting device is operatively associated with an LED array, and includes a driving circuit and a determining circuit. The driving circuit drives LED units of the LED array through scan lines and data lines of the LED array in such a way that a current flows through one of the LED units. The determining circuit selects a voltage at the data line that is coupled to said one of the LED units, and generates, based on a difference between a first sample voltage that is related to at least the selected voltage at a first time point and a second sample voltage that is related to at least the selected voltage at a second time point, a determination output indicating whether said one of the LED units is determined to have failed.

Semiconductor elements deteriorate or are destroyed due to electrostatic discharge damage. The present invention provides a semiconductor device in which a protecting means is formed in each pixel. The protecting means is provided with one or a plurality of elements selected from the group consisting of resistor elements, capacitor elements, and rectifying elements. Sudden changes in the electric potential of a source electrode or a drain electrode of a transistor due to electric charge that builds up in a pixel electrode is relieved by disposing the protecting means between the pixel electrode of the light-emitting element and the source electrode or the drain electrode of the transistor. Deterioration or destruction of the semiconductor element due to electrostatic discharge damage is thus prevented.
