    摘要: The invention describes a method of guiding a user (1) from an initial position (S) to a destination (T), chosen from among a plurality of possible destinations (T), in a public area (2) over which is distributed a plurality of lighting arrangements (Li, L2, . . . , Ln) each of which can be driven to render one or more light patterns from a plurality of light patterns. The method comprises the steps of determining the chosen destination (T) by obtaining a destination descriptor (13) from the user (1), allocating a specific light pattern from the plurality of light patterns to the chosen destination (T), providing the user (1) with a depiction (VT) of the specific light pattern allocated to the chosen destination (T), selecting a number of lighting arrangements (L1, L2, . . . , Ln) between a starting point (S) of the user (1) and the chosen destination (T), and driving the selected lighting arrangements (L1, L2, . . . , Ln) such that the selected lighting arrangements (L1, L2, . . . , Ln) between the starting point (S) of the user (1) and the chosen destination (T) render the specific light pattern. The invention further describes a system for guiding a user (1) from an initial position (S) to a destination (T) in a public area (2).

    摘要: A display device has an array of display elements (2) each driven by an input provided on a data conductor (6). These inputs are generated by data conductor addressing circuitry (9) which has a plurality of controllable driver circuits (32,34,40), each for providing an input to an associated data conductor. The number of controllable driver circuits is at least one greater than the number required for providing data to all data conductors. A reference driver circuit (30) is used for calibrating at least one of the controllable driver circuits whilst the other controllable driver circuits provide inputs to the data conductors. This provides a reduction in the spread of driver circuit outputs by calibration of the driver circuits using a reference driver circuit.

    摘要: The electrical circuit arrangement (A) for a display device (6) comprises an input terminal (11;13) a first memory element (M1); a driver element (D) coupled to the first memory element (M1); and a calibration circuit (S) coupled between the driver element (D) and the input terminal (11; 13). Information about first signal (Iprog;Idat) received via the input terminal (11; 13) is stored in the first memory element (M1). The driver element provides a second signal (Ilight; Iprog) via an output terminal (15; 11) in accordance with the information as stored in the first memory element (M1). The calibration circuit (S) matches a potential difference between the driver element (D) and the input terminal (11; 13) during a calibration phase prior to receiving the first signal (Iprog; Idat).

The pixel circuits in a column are divided into a plurality of groups of at least one pixel circuit. The active matrix display panel comprises at least one current mirror circuit associated with a first group, comprising a first current mirror, arranged to mirror a reference current flowing through a column line to a first current mirror output. Each pixel circuit in the first group comprises at least a first current-memory stage, having an output terminal connected to the light-emitting element, wherein the first current-memory stage is capable of drawing a current determined at least partly by the current mirrored to the first current mirror output through the output terminal. Each current mirror circuit comprises at least one additional current mirror, arranged to mirror a reference current flowing through an associated column line to an additional current mirror output, wherein each additional current mirror output is connected in parallel to the first current mirror output.
