Abstract

The invention provides a signal driving board, a production module and a production method of a display module. The signal driving board comprises a storage chip and a control chip, wherein the storage chip is used for storing data signals, the data signals comprise data signals corresponding to driving signals required by at least two different production processes, the control chip is used for detecting an input signal of a production process, accessing the storage chip according to the input signal, acquiring a data signal corresponding to the input signal, converting the data signal into acorresponding driving signal and outputting the driving signal to the display module so as to drive the display module to perform the corresponding production process. The signal driving board is advantaged in that the signal driving board is driven by the input signals of different production machines, different driving signals can be outputted to the display module, different production processrequirements are met, use efficiency of the signal driving board is improved, waste of the signal driving board is avoided, production cost is reduced, meanwhile, separate management and control of different signal driving boards are avoided, operation steps are simplified, and management and control difficulty of the signal driving board is reduced.

Description

technical field [0001] The present application relates to the display field, in particular to a signal driving board, a production module, and a production method of the display module. Background technique [0002] In the production process of liquid crystal display devices, it is necessary to use a signal driver board to perform tests such as lighting test, point detection test, and aging test on the display module. Due to the different purposes of each test process, the required test signals will also vary. For example, the test procedures such as lighting test and point detection test are to detect whether the display panel is displayed normally and to determine the grade and classify. At this time, the signal driver board is required to output normal power drive signals and corresponding screen drive signals to the display module; The purpose of the burn-in test process is to excite the subtle defects of the display panel, eliminate defective products, and improve the r...
