摘要： An image display system includes at least one user parameter analyser configured to determine at least one parameter associated with a user, an image display screen having luminous pixels, at least one graphics processing unit configured to process at least one first main image that can be displayed on the image display screen and that is representative of a first zone of a main scene. The system further includes at least one image buffer device configured to store at least the first main image, and a graphics controller configured to control a display of at least one first secondary image on the image display screen, the first secondary image having a first portion of the first main image included in the first main image and positioned within the first main image as a function of a first user parameter.

摘要： A method of controlling an optoelectronic device including display pixels arranged in rows and in columns. The optoelectronic device further includes first electrodes, each connected to the display pixels of at least one row, second electrodes, each connected to the display pixels of at least one column, and a circuit for controlling the first and second electrodes. The method includes, in a first phase, the activation of the display pixels connected to one of the first electrodes and to one of the second electrodes by the following steps, simultaneously carried out: taking one of the first electrodes to a first potential, the other first electrodes being maintained at a second potential smaller than the first potential; and taking one of the second electrodes to a third potential smaller than the second potential, the other second electrodes being maintained at a fourth potential greater than the third potential and smaller than the second potential.

摘要： An optoelectronic circuit for receiving a variable voltage containing alternating increasing and decreasing phases. The optoelectronic circuit includes assemblies of light-emitting diodes mounted in series; a current source connected to each assembly by a switch; for each switch, a first comparison module for comparing the current passing through the switch with a current threshold; a second comparison module for comparing a voltage representing the voltage at the terminals of the current source with a voltage threshold; and a control module connected to the first and second comparison modules and designed to control the opening and closing of the switches, during each increasing phase and each decreasing phase, according to signals supplied by the first and second comparison modules.
