US 2012/0256935 A1 · METHOD AND MOBILE TERMINAL FOR CONTROLLING DISPLAY OF WAITING INFORMATION DURING PROGRAM STARTUP

Abstract

A method and a mobile terminal for controlling display of waiting information during program startup are disclosed, relating to the field of computers. In the invention, a step of initializing a liquid crystal display (LCD) by a kernel is eliminated, and an LCD controller is reinitialized after the waiting information data in a bootloader display memory is copied to the display memory of the kernel, therefore, the LCD can directly read the waiting information data in the display memory of the kernel according to a display memory first address in the LCD controller. The waiting information data in the bootloader display memory is copied to the display memory of the kernel in advance, therefore, the displayed content is not changed completely for users. In addition, the step of initializing the LCD is eliminated, so that the phenomena of distortion, flashing, blurred screen and the like of the LCD screen display are completely avoided, the display quality during program startup is improved, and better visual experience is brought for users.

A method for controlling display of waiting information during program startup, comprising:

initializing, by a bootloader, a Liquid Crystal Display, LCD, according to a received kernel program startup instruction, distributing a first video memory, initializing a first address of the first video memory to an LCD controller and starting a kernel program after the pre-startup is completed;
distributing a second video memory after the startup of the kernel program, copying waiting information data in the first video memory to the second video memory and reinitializing a first address of the second video memory to the LCD controller;
and
acquiring the first address of the video memory from the LCD controller at a set frequency after the LCD is initialized by the bootloader, reading and displaying the waiting information data in the first video memory when the first address of the first video memory is acquired, and reading and displaying the waiting information data in the second video memory when the first address of the second video memory is acquired.
