EKB-3P-DLP4500EVM: Wrong patterns are displayed.

Kokoro Fujiwara

Part Number: DLPLCR4500EVM

Hello, 

I have encountered some problems when using LightCrafter4500 with GUI ver4.4.1.

In the Pattern Sequence mode with internal trigger, when the number of patterns are more than six and Repeats , incorrect patterns are displayed.

I set the Exposure time =Pattern Period =10 ms.

The sequence are read from the Flash memory and the version of the Firmware is 4.4.0.

Could you tell me how to deal with?

Best Regards,

Kokoro

    Hello Kokoro,

    Welcome back to the E2E forum and thank you for your interest in DLP® technology!

    This is a peculiar behavior that you are reporting. Please allow us until the end of the week to investigate this. In the meantime, can you attached an image or command list of your process for sending these patterns?

    Hello Austin,

    Thank you for your reply.

    I attached the command list. The Pattern Sequence is as follows.

    S3:G7,S4:G7,S5:G7,S6:G7,S7:G7,S8:G7

    Regards,

    Hello Kokoro,

    Thanks for sharing the pattern sequence. Could you please share the .ini file for analysis.

    What do you mean when you say you see incorrect patterns are displayed. Also What is the desired pattern you are trying to achieve

    Hello Akhil,

    Actually, I don't change the .ini file from the Default.ini.

    My goal is to modulate the laser of my laboratory by DMD and I want to show  pattern sequence repeatedly which contains around 20 patterns. 

    When I repeat the pattern sequence, maybe reset ocuurs (I mean, all mirrors are on OFF states) between the sequence.

    Also, even though I set the same value to Exposure time and Pattern Period, there is the OFF times between the pattern.

    For example, when the Exposure time and Pattern Period=10ms, DMD only show the appropriate pattern every other 10ms.

    Below is the .ini file.

    Hi Kokoro,

    The team will look into the detail of the .ini file. Please expect the response by the middle of next week.

    Thanks,

    Hello,

    I solved the problem.

    The cause was the internal buffer load issue.

    When I upload the 1bit -plane image, I can see the correct image.

    Thank you.
