- Fig. 1 A and 1B illustrate respective exterior and interior views of a hand-portable electronic device 10;
- Fig. 2 illustrates the functional components of the hand portable device 10; and Fig. 3 illustrates illumination circuitry.
- Fig. 1A illustrates a hand-portable electronic device 10 having an exterior 12 and comprising: a display 14 and a user input device 16, which in this example is a keypad.
- the display 14 and keypad 16 are accessible through apertures in the front face 17 of the body 18 of device 10.
- the keypad 16 is lit from the interior of the body 18 by a pair of RGB light emitting diode (LED) devices 20 (not shown in Fig 1A).
- LED light emitting diode
- Fig. 1 B shows a view of the reverse of the front face 17 from the interior of the body 18.
- the front face 17 has a display aperture 15 and key aperture 17.
- a translucent key mat 19 is placed over the key apertures 17 and partially protrudes through the apertures to form the keypad 16.
- the RGB LEDs are located adjacent the key mat 19.
- Light guides may be used to direct light from the RGB LEDs 20 within the interior of the body 18. In this example, when the RGB LED devices 10 are activated the light they produce is emitted through the keypad 16 thereby illuminating an exterior portion of the device.
- all or part of the body 18 may be translucent and light produced by RGB LED devices in the interior of the body may be emitted through the translucent portions of the body thereby illuminating an exterior portion or portions of the device 10.
- Fig. 2 illustrates the functional components of the device 10.
- the device 10 comprises the display 14, the user input device 16, a processor 22 and a memory 24.
- the processor 22 is connected to read from and write to the memory 24, is connected to provide control signals to the display 14 and is connected to receive control signals from the user input device 16.
- the device 10 also comprises illumination circuitry 30 including the RGB LED devices 20, which are controlled via the illumination control signal 31 by the processor 22.
- the illumination circuitry 30 is illustrated in more detail in Fig. 3. It illuminates an exterior portion of the device 10, but not necessarily the display 14. In the example described it is used to illuminate the translucent keypad 16 from behind.
- the illumination circuitry comprises two RGB LED devices 20.
- Each RGB LED device comprises a red LED 32, a green LED 34 and a blue LED 36.
- the red LEDs 32 of the RGB LED devices 20 are connected in series.
- the electric current through them is controlled by a first current control device 41 , which in this example is a bipolar transistor.
- the green LEDs 34 of the RGB LED devices are connected in series.
- the electric current through them is controlled by a second current control device 42, which in this example is a bipolar transistor.
- the blue LEDs 36 of the RGB LED devices are connected in series.
- the electric current through them is controlled by a third current control device 43, which in this example is a bipolar transistor.
- the control signal 31 from the processor 22 comprises three separate control signals.
- One of the control signals, the Red control signal 51 is used to control the first current control device 41.
- the Red control signal 51 is divided by series connected resistors R1 and R2 and the divided signal is provided to the base of the transistor 41.
- One of the control signals, the Green control signal 52 is used to control the second current control device 42.
- the Green control signal 52 is divided by series connected resistors R3 and R4 and the divided signal is provided to the base of the transistor 42.
- One of the control signals, the Blue control signal 53 is used to control the third current control device 43.
- the Blue control signal 53 is divided by series connected resistors R5 and R6 and the divided signal is provided to the base of the transistor 43.
- the processor 22 controls the image presented by the display 14.
- the display will comprise an NxM array of pixel clusters, where each pixel cluster comprises a red colored pixel, a green colored pixel and a blue colored pixel.
- the color produced by a particular pixel cluster (n, m) is determined by the intensity of the red pixel, the intensity of the green pixel and the intensity of the blue pixel. These intensities can be represented as the vector (R, G, B) n m .
- An image on the display is defined by an NxM array of such vectors and the processor 22 provides this array as pixel control data to the display 14.
- the image presented by the display 14 may include a background image with information such as text presented in the foreground over the background image. Typically such a background image is selectable by a user of the device 10.
- the processor 22 is operable to determine a first color value that is dependent upon the image presented on the display 14 and consequently control the illumination circuitry 30 to illuminate an exterior portion of the device 10 with light the color of which is dependent upon the first color value.
- the processor may determine a new first color value automatically, for example, when the image presented on the display 14 changes or when the background image to the display is changed by a user.
- the processor 22 processes the pixel control data to identify a conspicuous color in the display.
- the first color value may then be set to a value (R1 , G1 , B1 ) that attempts to accurately reproduce that conspicuous color or a color similar to it.
- the first color value may be set to a value (R1 , G1 , B1 ) that attempts to accurately reproduce a color that is contradistinctive to the conspicuous color.
- the conspicuous color may for example be the predominant color in the image presented on the display or the predominant color in a portion of the image presented. It may alternatively be a particularly vivid color that is present in the displayed image. Typically an algorithm may be used to determine the conspicuous color.
- One algorithm associates a single reference color with any one of a plurality of colors than are close to it in the color spectrum. If each reference color q has an associated vector (Ri, G ⁇ , B ⁇ ), then a pixel is associated with that reference color if for the pixel's color vector (R, G, B) nrn :
- the Ci that has the greatest number of pixels associated with it is the predominant color and its vector is set equal to (R1 , G1 , B1).
- the processor then converts the determined first color value (R1 , G1 , B1) into the illumination control signal 31.
- the processor 22 then converts the red illumination value (R1) into the Red control signal 51 using red calibration data stored in the memory 24. Using this red calibration data the processor 22 determines the voltage that needs to be provided by the Red control signal 51 , to create the required intensity of red light from the red LED 32.
- the red calibration data in this example, depends upon the characteristics of the red LED 32, the values of R1 and R2 and the characteristics of the first current control device 41.
- the processor 22 also converts the green illumination value into the Green control signal 52 using green calibration data stored in the memory 24. Using this green calibration data, the processor 22 determines the voltage that needs to be provided by the Green control signal 52 , to create the required intensity of green light from the green LED 34.
- the green calibration data in this example, depends upon the characteristics of the green LED 34, the values of R3 and R4 and the characteristics of the second current control device 42.
- the processor also converts the blue illumination value into the Blue control signal 53 using blue calibration data stored in the memory 24. Using this blue calibration data, the processor 22 determines the voltage that needs to be provided by the Blue control signal 52 , to create the required intensity of blue light from the blue LED 36.
- the blue calibration data in this example, depends upon the characteristics of the blue LED 36, the values of R5 and R6 and the characteristics of the second current control device 43.
- the processor 22 may provide the illumination control signal 31 to the illumination circuitry 30 automatically whenever the display 14 is in use. Alternatively, the processor 22 may selectively provide the illumination control signal 31 to the illumination circuitry 30. For example, the processor 22 may provide the illumination control signal 31 when the state of the device 10 changes. If the device 10 is a radio cellular telephone, such a change of state may, for example, occur when there is an incoming call or when an alarm, such as an alarm clock, is activated, or when the device wakes-up from a sleep mode.
- the hand-portable electronic device determines the color to be generated by the LEDs. It is also possible for the user to select the color to be generated by the LEDS.
- the hand-portable electronic device may then determine the image that is to be displayed, for example, it may select a particular background image that matches the selected color.
