With reference to Fig. 1 to Fig. 3, the present invention relates to a kind of liquid crystal display electrical adjustment time optimization method, it is characterized in that, carry out as follows:

1) Connect the signal line and wait for the LCD screen to be adjusted to come out;

2) Press the setting button on the keyboard to start electrical adjustment;

3) Send the electrical adjustment command to the programming control card, that is, the ISP card;

4) Wait for the preset time;

5) Send a command to obtain the return information. If the correct return information is obtained, go to the next step. If the correct return information cannot be obtained, return to step 4. If the number of times the command is sent exceeds 5 times, go to step 10. step;

6) Waiting for another preset time;

7) Send a command to obtain the return information. If the return information of the completion of the electrical adjustment is obtained, go to the next step. If the return information of the completion of the electrical adjustment cannot be obtained, return to step 6. If the number of sending commands exceeds 20 times Go to step 10;

8) If all electrical adjustment commands are executed normally, go to the next step, otherwise, return to step 3 after replacing with another electrical adjustment command;

9) Display PASS, go to step 11;

10) Display FAIL, go to step 11;

11) End the electrical adjustment and wait for the next start.

The above-mentioned ISP card is required to have the function of adding storage commands and return information. The ISP card can store commands and return information. ISP card communication can get feedback in time when the adjustment is abnormal and after the adjustment is completed, so as to achieve the function of optimizing the electrical adjustment time.

The liquid crystal display to be adjusted requires its software to be able to return the preset information to the ISP card after receiving the command and completing the electrical adjustment command.

The specific implementation process:

Hardware equipment: use all hardware adjusted by the original electrical.

Software equipment: self-developed electrical adjustment software

Implementation means:

1. The electrical adjustment program on the PC will wait for a period of time after sending the electrical adjustment command, and then fetch the data on the ISP card. If the data indicates that the command has been received, it will enter the next step, otherwise resend the electrical adjustment command until 5 Anomalies are displayed for the second time;

2. Wait for a while, and then fetch the data on the ISP card, if the data indicates that the electrical adjustment is completed, go to the next step, otherwise continue to wait, and then fetch the data on the ISP card, until the total waiting time reaches the upper limit , an exception is displayed;

3. Send another electrical adjustment command, repeat the first step until all electrical adjustments are completed, then enter the next step;

4. It shows that the adjustment of the monitor is completed, and the program thread ends, prompting the operator to make the next electrical adjustment.

1. Adjustment steps:

A method for optimizing the electrical adjustment time of a liquid crystal display is carried out as follows:

1) Connect the signal line and wait for the LCD screen to be adjusted to come out;

2) Press the setting button on the keyboard to start electrical adjustment;

3) Send electrical adjustment commands to the programming control card (ISP card);

4) Wait for the preset time;

5) Send a command to obtain the return information. If the correct return information is obtained, go to the next step. If the correct return information cannot be obtained, return to step 4. If the number of times the command is sent exceeds 5 times, go to step 10. step;

6) Waiting for another preset time;

7) Send a command to obtain the return information. If the return information of the completion of the electrical adjustment is obtained, go to the next step. If the return information of the completion of the electrical adjustment cannot be obtained, return to step 6. If the number of sending commands exceeds 20 times Go to step 10;

8) If all electrical adjustment commands are executed normally, go to the next step, otherwise, return to step 3 after replacing with another electrical adjustment command;

9) Display PASS, go to step 11;

10) Display FAIL, go to step 11;

11) End the electrical adjustment and wait for the next start.

Second, the electrical adjustment time optimization method:

In the production of liquid crystal displays, for self-adjusting electrical adjustments (such as AutoColor and AutoConfig), due to differences in models and differences in electrical performance of the same model, the adjustment time is uncertain.

The previous technology is to wait for the preset time (usually set to the longest so that all monitors can be adjusted normally) after sending the adjustment command, and then directly display "Pass" or send another electrical adjustment command. The problem is that it cannot Knowing whether the order is received and the adjustment is completed, the production efficiency is also relatively low (see the comparison table with the prior art).

The improvement of this proposal is as follows:

1. Hardware

Comparing the hardware part with the previous technology, there is no additional equipment, but there are requirements for the adjustment equipment and the functions of the liquid crystal display to be adjusted, specifically:

a.ISP card: It is required to increase the function of storing commands and returning information;

b. LCD display to be adjusted: its software is required to be able to return the preset information to the ISP card after receiving the command and completing the electrical adjustment command;

c. Industrial control PC: Due to the use of parallel port to simulate IIC communication, the current technology can only send commands, but cannot receive commands, and its hardware part has not changed;

2. Software

On the premise that the ISP card can store commands and send back information, and the liquid crystal display to be adjusted supports the return, after sending the electrical adjustment command, communicate with the ISP card many times, and get feedback in time after the adjustment is abnormal and the adjustment is completed, to achieve Function to optimize electrical adjustment time.

Compared with the prior technology, the advanced features are:

1. The prior technology cannot know whether the command is sent successfully, and the operator needs to observe the liquid crystal display to be adjusted to make a judgment. This proposal can detect abnormalities and immediately feedback to the operator;

2. The prior technology cannot know whether the electrical adjustment is completed, and the operator needs to observe the liquid crystal display to be adjusted to make a judgment. This proposal automatically enters the next electrical adjustment after the electrical adjustment is completed or feeds back to the operator;

3. The waiting time of the previous technology is set to be the longest, and the efficiency of electrical adjustment is low. The waiting time of this proposal is self-adaptive, which is the actual adjustment time, and the efficiency reaches 100%.

The above descriptions are only preferred embodiments of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention shall fall within the scope of the present invention.
