Embodiment Construction

[0030] In order to make the purpose, technical means and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings.

[0031] figure 2 It is a schematic flow chart of the method for solving the radio frequency interference of the LCD screen of the terminal in this application. like figure 2 As shown, the method includes:

[0032] Step 201, determine the working frequency point of the current working mode of the terminal, and determine the MIPI clock selectable on the terminal screen and the corresponding interference frequency point.

[0033] The default LCD MIPI clock can be used for the first boot of the terminal. For TMO mode, when the terminal is successfully connected to the network, the CP will notify the AP of the working frequency; for DMO mode, the working frequency is directly recorded on the AP side. The high-level software of the AP can notify the driver softwar...

Abstract

The application discloses a method of avoiding radio-frequency interference of a LCD screen of a terminal to solve the problem of service performance reduction caused by radio-frequency interference of the screen. The method comprises the following steps: determining an MIPI work clock selected by a terminal screen and a corresponding interference frequency point; dynamically configuring the MIPI clock of the terminal screen to make sure that the interference frequency point produced by the configured MIPI clock will not coincide with a working frequency point in a current working mode; and displaying the terminal screen according to the configured MIPI clock. Through the application, the voice quality is improved, the data service rate is increased, and the coverage of a base station is expanded.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method for solving radio frequency interference by an LCD screen of a terminal. Background technique [0002] With the continuous development of communication technology, there are more and more working modes of mobile terminals. At present, there are five-mode ten-band or five-mode fourteen-band mobile terminals for civilian use, supporting global roaming.
