The device is configured to implement at least one signaling function of a motor vehicle. The device includes display means including a display zone intended to be disposed on the vehicle, the display means being adapted to display pictograms in the display zone, each pictogram emitting a light beam having at least in part the statutory photometric characteristics of at least one of said at least one signaling functions. ## Claims ### Claim 1 A signaling device for a motor vehicle adapted to display pictograms, comprising: a display zone disposed on the vehicle, a complementary zone that surrounds the display zone, and circuitry configured to display a pictogram in the display zone, the pictogram emitting a light beam that partially meets in shape and intensity statutory photometric characteristics of at least one signaling function; and emit a complementary light beam from the complementary zone, wherein the complementary light beam compensates differences of shape and intensity of the pictogram, so that a combination of the display zone light beam and the complementary light beam meets in the shape and intensity statutory photometric characteristics. ### Claim 2 (depends on 1) The signaling device according to claim 1, further comprising: a light source adapted to emit light rays and means for distributing the light rays over the complementary zone in order to form the complementary light beam. ### Claim 3 (depends on 1) The signaling device according to claim 1, wherein the pictogram relates to emergency situations. ### Claim 4 (depends on 1) The signaling device according to claim 1, wherein the pictogram relates to general traffic information. ### Claim 5 (depends on 1) The signaling device according to claim 1, wherein the pictogram is dynamic. ### Claim 6 (depends on 1) The signaling device according to claim 1, wherein the circuitry is further configured to control automatically the display of the pictograms as a function of parameters of the vehicle or the environmental situation of the vehicle. ### Claim 7 (depends on 6) The signaling device according to claim 6, further comprising: sensors disposed on the vehicle, the sensors being configured to evaluate the environmental situation of the vehicle. ### Claim 8 (depends on 6) The signaling device according to claim 6, wherein the circuitry is further configured to set the parameters of the display of the pictograms. ### Claim 9 (depends on 1) The signaling device according to claim 1, wherein the display zone is a liquid crystal, plasma, inorganic or organic light-emitting diode type screen. ### Claim 10 (depends on 1) The signaling device according to claim 1, wherein the display zone includes at least one laser source adapted to form a laser beam, a transmission surface defining the display zone, and the circuitry is further configured to sweep the laser beam over the transmission surface. ### Claim 11 (depends on 1) The signaling device according to claim 1, wherein the display zone includes a surface light guide including groups of prism-type structures or cavities on one of its lateral faces. ### Claim 12 (depends on 1) The signaling device according to claim 1, wherein the display zone includes at least one light source in the form of at least one light-emitting diode, a transmission surface defining the display zone, and a matrix of micromirrors configured to reflect the light rays from the at least one light source toward the transmission surface. ### Claim 13 (depends on 1) A motor vehicle signal light including a signaling device, according to claim 1, adapted to display pictograms. ### Claim 14 (depends on 1) The signaling device according to claim 1, wherein an appearance of the pictogram evolves dynamically according to a distance between a following motor vehicle and the motor vehicle. ### Claim 15 (depends on 1) The signaling device according to claim 1, further comprising: a second complementary zone that surrounds in part the complementary zone, the second complementary zone emitting a second complementary light beam. ### Claim 16 (depends on 15) The signaling device according to claim 15, wherein the second complementary light beam complements a turn indicator function of the pictogram.
