    摘要： An electronic display assembly includes an electronic display and a panel located within a housing such that the panel is spaced apart from a rear surface of the electronic display. An airflow pathway fluidly connected to an ambient environment extends through at least a portion of the housing. At least a portion of the airflow pathway extends behind the electronic display and forward of the panel. At least one electronic component for operating the electronic display assembly is located at a rear surface of the panel. The at least one electronic component may be directly adhered to the rear surface of the panel, such as to provide thermal coupling.

    摘要： An optical device with one or more spatially variable optical response characteristics is disclosed. The optical device includes a cell including a liquid crystal material contained between a pair of substrates, each substrate having a transparent conductive layer provided thereon. An electrode connection contacts each transparent conductive layer. A driving signal source is in electrical communication with each electrode connection for application of a driving signal to the cell. An applied driving signal to the electrode connections from the driving signal source creates a voltage gradient in a gradient direction along the pair of transparent conductive layers leading away from the electrode connections. The voltage gradient is received by the liquid crystal material to produce a gradient in at least one optical response characteristic across at least a portion of the device.

    摘要： A dimming device for controlling a dimming rate of a dimming member includes a DC/AC inverter to convert a direct-current voltage into an alternating-current voltage requiring a predetermined period and amplitude; and an inverter drive unit to drive the DC/AC inverter based on an opening and closing control signal. The inverter drive unit includes a command value generation unit to generate an opening and closing command value for controlling an opening and closing state of a switching element provided in the DC/AC inverter.

    摘要： In a driver circuit, a bias voltage generation circuit generates and outputs a bias voltage for determining a bias current of an output amplifier. A memory stores a trimming code with which a slew rate of an output voltage outputted by the output amplifier is adjusted to fall within a target range set in advance. In an adjustment mode for adjusting the slew rate, a slew rate adjustment circuit adjusts the slew rate of the output amplifier based on a trimming code inputted from a shipping inspection device. Then, in a normal operation mode, the slew rate adjustment circuit changes a resistance value based on the trimming code stored in the memory to change a bias level of the bias voltage generation circuit and adjust the slew rate of the output amplifier.
