Abstract

Method for controlling a display device in an electronic device and associated control device. The electronic device includes a control unit and the display device comprising a plurality of display elements, a display controller and a switching circuit. The display elements have a plurality of pictograms. The display controller having a plurality of storage elements associated with the display elements. The method includes the steps of writing into the storage elements of a contents for display on the display elements, the configuration in standby mode of the electronic device making the storage elements associated with the display elements by the control unit inaccessible, the detection of an event to be indicated by display, and the control of a switching circuit to vary the active pictograms by alternately displaying the contents of at least two of the storage elements on the same display element.

Claims

1. Method for controlling a display device in an electronic device, the said display device comprising at least one display element, one display controller and one switching circuit, the said at least one display element comprising at least one pictogram, the said display controller comprising a first memory comprising at least a storage element associated with the said at least one display element and a second memory comprising at least one storage element, said method comprising the following steps:

writing of a contents into the said at least one storage element of the said first memory and into the said at least one storage element of the said second memory,

configuration in standby mode of the said electronic device,

detection by a microcontroller connected to the said switching circuit, of an event to be indicated by display,

wherein, said method further comprising the following steps;

blocking access to said first memory and said second memory after said configuration in standby mode and before said detection of an event, and,

control of the said switching circuit to modify the display of the said at least one display element by alternately associating it with the said at least one storage element of the said first memory and with the said at least one storage element of the said second memory.

2. Method according to claim 1 wherein the step of writing a contents into the said storage elements is triggered by a detection by the said control unit of a signal for changeover to standby mode.

3. Method according to one of claim 1, wherein the detected event corresponds to the receipt of a data frame emitted by a remote control of the said electronic device.

4. Method according to one of claim 1, wherein the step for detecting an event corresponds to the detection by a microcontroller connected to the said switching circuit of the variation of a signal following the pressing of a key of the keyboard of the said electronic device.

5. Method according to one of claim 1, wherein the step for detecting an event corresponds to the detection, by a microcontroller connected to the said switching circuit, of the equality between the current time and a preprogrammed time, leading to the activation of a function of the said electronic device.

6. Display device in an electronic device comprising at least one display element, a display controller and switching means,

said at least one display element comprising at least one pictogram,

said display controller comprising

a first memory composed of at least one storage element associated with said at least one display element, wherein:

said display controller further comprises a second memory, said display device comprising means for blocking access to said first memory and said second memory adapted to be triggered by said standby mode configuration of said electronic device,

said switching means being adapted for associating at least one display element alternately to said second memory and to said at least one storage element of the said first memory, and being able to be triggered by said detected event.

7. Display device according to claim 6 wherein the said electronic device is a receiver of audiovisual programmes.

8. Display device according to one of claim 6 wherein comprising the said at least one pictogram indicates the receipt of a command emitted by the remote control of the said electronic device.
