Problems solved by technology

When the RGB display without RAM is on the screen, the PCLK clock signal sent at a certain frequency will affect the channel corresponding to ARFCN, so that the signal transmitted by the mobile communication network through the channel cannot be normal by the mobile station. reception, seriously affecting the RF performance of the mobile station

Embodiment Construction

[0038] In daily life, when the RGB display screen without built-in RAM in the mobile station is on, the application processor (Application Processor, AP for short) in the mobile station will send a PCLK clock signal at a stable frequency. The higher harmonics of the PCLK clock signal will cause interference to the channel corresponding to the ARFCN (Absolute Radio Channel Number).

[0039] For example, for a mobile phone with a display screen of 4.7 inches, the frequency of the clock signal that can be provided by the application processor of the baseband chip of the mobile phone is 27.428571MHz, and the higher harmonics of the clock signal will affect the enhanced global system for mobile communication. (EnhancedGlobalSystemforMobileCommunications, referred to as EGSM) 1012 channel and 124 channel receiving frequency caused serious interference, so that the signal transmitted through the 1012 channel and 124 channel may not be normally received by the mobile phone.

Abstract

The invention relates to a mobile station, a method and device for improving the sensitivity of the mobile station. The method includes the following steps that: first pixel clock signals of mobile station display peripheral equipment are obtained; a channel used by next time slot data to be received by a mobile station receiver is obtained; whether the obtained channel is in the range of channels which are interfered by the first pixel clock signals of the mobile station display peripheral equipment is judged; and when the obtained channel is in the range of the channels which are interfered by the first pixel clock signals, second pixel clock signals are adopted as the clock signals of the mobile station display peripheral equipment. With the method provided by the above technical schemes adopted, the sensitivity of the mobile station can be effectively improved, and the use experience of a user can be enhanced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for improving the sensitivity of a mobile station, and a mobile station. Background technique [0002] The mobile station is the user equipment of the mobile communication system, including vehicle-mounted stations, portable stations and handsets. [0003] Display screens of mobile stations can generally be classified into display screens with random access memory (Random Access Memory, RAM) and display screens without RAM. Among them, the display screen with RAM, after receiving the serial data sent from the outside, can temporarily store the received data in the RAM, and then the integrated control circuit of the display screen will convert the stored data into parallel After the data is displayed, it is displayed on the display screen or the data is refreshed. The display screen without built-in RAM will always be in the state of receiving external...
