Abstract

본 발명은 발광소자의 휘도조절방법에 관한 것으로서, 종래 단말기의 모든 발광소자로 같은 양의 전류를 인가하므로서 발광소자의 색상, 특성, 또는 빛파장의 차이로 인해 사람 시각의 인지능력차이에 비해 빛의 파장이 짧은 색깔이 더 흐리게 보이는데 이를 개선코자 발광소자를 아주 빠른 속도로 점멸시켜 발광소자가 지속적으로 켜져 있는 상태보다 흐르게 느껴지게 하므로서 빛의 밝기를 조절하도록 한 것이다.The present invention relates to a brightness control method of a light emitting device, and by applying the same amount of current to all the light emitting devices of the conventional terminal, due to the difference in color, characteristics, or light wavelength of the light emitting device, compared to the difference in cognitive ability of human vision The shorter wavelength of the light appears to be more blurred. To improve this, the light emitting device blinks at a very high speed so that the light emitting device feels flowing more than the state in which the light is continuously turned on.

Claims (1)

발광소자의 고속점멸시간에서 마지막 발광소자의 온/오프 제어값이 온상태일시 현재 발광소자가 온상태인가를 검색하는 단계와, 상기 검색한 현재 발광소자가 온상태일 경우 해당 발광소자를 오프시키도록 발광소자 구동수단의 제어값을 변환 출력하여 실제의 발광소자의 상태를 바꾸는 단계와, 상기 검색한 발광소자가 오프상태일 경우 해당 발광소자를 온시키도록 발광소자 구동수단의 제어값을 변환출력하여 실제 발광소자의 상태를 바꾸는 단계로 이루어짐을 특징으로 한 발광소자의 휘도조절방법.Searching whether the current light emitting device is in an on state when the on / off control value of the last light emitting device is in an on state at a fast flashing time of the light emitting device; and if the searched current light emitting device is in an on state, turning off the corresponding light emitting device. Converting and outputting the control value of the light emitting element driving means so as to change the state of the actual light emitting element; And changing the state of the actual light emitting device. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
