Therefore, when the number of blinking patterns on the portable electronic device increases, the memory capacity requirement for storing the corresponding light source control parameters also increases, and the manufacturing cost of the portable electronic device will also increase simultaneously.
[0003] In addition, when the number of blinking patterns increases, it will take more time to find out the light source control parameters corresponding to the events that occur in the memory, resulting in the LED not being able to respond to the events that occur in real time to adjust the brightness of the light or Chroma

The invention discloses portable electronic device and control method of light source thereof. The portable electronic device comprises a main control assembly, a light source control assembly and a light source assembly which is used for generating a light source. The control method comprises the following steps of: storing a plurality of light source control parameters in the main control assembly; responding an input signal, and outputting one of the light source control parameters by the main control assembly to the light source control assembly; responding the output light source control parameter, and generating and transmitting a light source control signal by the light source control assembly to the light source assembly, wherein the light source control signal is used for control the brightness of the light source generated by the light source assembly.
Description
technical field [0001] The present invention relates to a portable electronic device and its light source control method; more specifically, it relates to a portable electronic device that stores multiple light source control parameters in the memory of the main control component to control the brightness of the light source Electronic device and control method. Background technique [0002] Portable electronic devices on the market today, such as mobile phones and personal digital assistants (Personal Digital Assistants; PDAs), usually have light-emitting diodes (Light-emitting Diodes; LEDs) of different colors, which are used to blink to indicate the occurrence of different events, such as mobile phones When in standby mode, a green light-emitting diode flashes to indicate that the mobile phone is in standby mode, or when the battery is low in power, a red light-emitting diode flashes to inform the user that the battery should be replaced or charged. However, as far as th...
