Abstract

The utility model relates to a method that a mobile phone is compatible with different display devices, which comprises the following steps: Step 1. a standard series number list is compiled for a LCD device; Step 2. relevant driving motions of LCD are defined to be a uniform dynamic function pointer; Step 3. a space is cultivated inside the flash disk of the mobile phone to store condition codes; Step 4. a condition code is written into the fixed storage space inside the flash disk of the mobile phone; Step 5. after the mobile is equipped with batteries and switched on, a condition code is released from the fixed location inside the flash disk that is cultivated in Step 3; by matching with the standard series number list, a corresponding LCD device driving function can be found and the function pointer points to the corresponding driving function; Step 6. the LCD device is initialized by the driving function and displaying of the LCD device is controlled properly by operation of the driving core of the LCD device. The utility model has the advantages that the method can download fixed program into the mobile phones, which improves efficiency of development and production for mobile phones largely and saves cost as well as time.

Description

technical field [0001] The invention relates to a mobile phone compatibility method, in particular to a mobile phone compatibility method for different display devices. Background technique [0002] With the rapid development of communication technology, mobile communication has gradually become the most timely and convenient way of communication in modern society. The diversification of communication terminal products has become a trend. Various liquid crystal display devices emerge in endlessly, and different display devices The driver chips used are often different. Therefore, some unnecessary operations have to be done in the process of mobile phone development and production to be compatible with different display devices, such as repeated compilation and repeated downloads, which greatly reduces It reduces the efficiency of research and development and production, but also increases labor costs, resulting in a lot of waste. Contents of the invention [0003] In orde...
