Embodiment Construction

[0046] Below according to accompanying drawing and embodiment the present invention will be described in further detail:

[0047] According to shown in Fig. 1, the present invention comprises main control unit 1, tested LCD2, setting module 3, voltage module 4 and relay module 5, in the present invention, main control unit 1 adopts 80C51 chip, for example, the adopted model For WINBOND 78LE516B.

[0048] As shown in Figure 1, there is an LCD driver 21 in the LCD2, and the main control unit 1 is connected to the LCD2. .

[0049] As shown in FIG. 1 , the setting module 3 transmits adjustment data to the programming management module 11 , such adjustment data includes contrast adjustment values ​​and LCD display status values. Burning management module 11 makes LCD2 display accordingly according to the data delivered by setting module 3, obtains the contrast adjustment value, calculates the OTP burning parameter value of LCD driver 21, sends burning instruction to LCD2, transmi...

Abstract

The present invention is method and system for controlling the burning of detection OTP. The method includes the following steps: 1. setting LCD contrast regulating range, 2. starting LCD, 3. regulating LCD contrast to determine the OTP burning parameter of LCD driver, and 4. applying burning voltage to the LCD driver and transferring the OTP burning parameter to the LCD driver. The system includes a main control unit with burning control module, a tested LCD, and a setting module. After the setting module transfers the adjusting data to the burning control module, the burning control module makes the LCD display correspondingly, obtains contrast regulating value, calculates the OTP burning parameter of the LCD driver, sends burning command to the LCD, transfers the OTP burning parameter of the LCD driver and controls the power on-off of the LCD driver. The present invention has high production efficiency.

Description

technical field [0001] The invention relates to detection, in particular to an OTP programming control method and system. Background technique [0002] In today's daily life, the mobile phone has become an almost indispensable communication tool in life and work, and its demand has been greatly increased. However, as one of the most important parts of the mobile phone, the liquid crystal display LCD (or liquid crystal display module LCM) has Has been plagued by the problems of low yield rate and low production efficiency. The biggest problem is that the yield rate is too low due to the lack of effective control of the process flow. [0003] In response to this point, manufacturers of various LCD drivers have added a function called one time program (OTP: ONE TIME PROGRAM). This function is to add a register in the LCD driver, and then confirm the plate with deviation in the liquid crystal voltage, and then manually confirm the value of the deviation, correct it by burning,...
