[0070] Propose the fourth embodiment of the data processing method of the intelligent terminal constant current IC chip of the present invention based on the above-mentioned embodiment, refer to Figure 4 , in this embodiment, the data processing method of the smart terminal constant current IC chip also includes:
[0071] Step S180, acquiring the configuration information of the constant current IC chip when the display screen is not powered on for the first time;
[0072] Wherein, the configuration information of the constant current IC chip includes first configuration information and / or second configuration information. When the display screen is not powered on for the first time, it means that the current display screen is not powered on for the first time. The constant current IC chip is initialized with a security value, and the first configuration information and the second configuration information are stored, so the configuration information of the constant current I...

The present invention discloses a data processing method of an intelligent terminal constant current IC chip. The method includes the following steps that: when a display screen is electrified for the first time, a main control chip initializes the constant current IC chip with a preset safe value; the current value and voltage value of the output end of the initialized constant current IC chip are obtained; and when the obtained current value is beyond a preset current range, and the obtained voltage value is within a preset voltage range, configuration information corresponding to the specifications of the display screen is acquired based on the current value and voltage value, and the configuration information is stored. The invention also discloses a data processing device of the intelligent terminal constant current IC chip. With the data processing method and data processing device of the invention adopted, the configuration information of the constant current IC chip can be acquired and stored, so that the main control chip can acquire the configuration information of the corresponding constant current IC chip according to the specifications of the current display screen, and the main control chip can be compatible with the constant current IC chips of display screens in different specifications, and the compatibility of the constant current IC can be improved.
Description
technical field [0001] The invention relates to the technical field of display screens, in particular to a data processing method and device for a constant current IC chip of an intelligent terminal. Background technique [0002] At present, with the continuous development of display screen technology, specifications of screen bodies of display screens of smart terminals including smart TVs and computers are becoming more and more abundant. During the operation of the smart terminal, displays of different specifications need to use different constant-current IC chips to control the light bar, so that the display has a good backlight effect, so TV manufacturers need to produce a variety of constant-current IC chips to Matching smart TV displays with different specifications causes the control chip to be unable to control constant current IC chips of different specifications, resulting in the control chip being unable to be compatible with different constant current IC chips. ...
