A program burning method and system for touch chip under cob process

Abstract

The invention belongs to the field of a touch screen design and provides a program burning method and system of a COB (Chip On Board) process lower touch chip. According to the method and the system, production people pre-configure an electric level of a terminal which is arranged on a touch screen module and is connected with a main board, and configure a corresponding pin of an interface to be connected in the touch screen module as a high electric level; and after the touch screen module is connected to the main board, an electric level state of an interface which is arranged on the main board and is connected with the touch screen module is judged to identify a touch screen module manufacturer, so as to call a pre-stored corresponding touch program and burn into the touch chip. The method does not need external equipment and can pre-store all touch programs which are possibly needed; and one set of a program is adopted to realize the burning of the touch program of a plurality of the touch screen module manufacturers, so that the time and labor are saved and the production efficiency of products is improved.

Description

technical field [0001] The invention belongs to the field of touch screen design, and in particular relates to a program burning method and system for a touch chip under a COB process in the production process of a touch screen terminal. Background technique [0002] With the development of touch screen terminals, the competition is becoming more and more fierce. The result of fierce competition is that the entire terminal industry has entered the era of meager profits, and various manufacturers have racked their brains to reduce costs. [0003] Traditional touch screen terminals use COF technology, such as figure 1 shown. In the COF process, the touch chip is integrated in the touch screen module, and this process will increase the cost of the touch screen module manufacturer. In response to this, the prior art proposes a COB process, such as figure 2 As shown, under the COB process, the touch chip is directly welded on the main board of the touch screen terminal, and t...
