Is there any plan for 120hz frame rate?

Is there any plan for 120hz frame rate?

Hi,

Not to mention 3D application, there are some demand in scientific research fields in need of fast frame rate. Most of the time, they (including myself) develop custom solution. Now many LCD monitors are 120hz capable. It is good for 60hz 3D movie, but it is also great for 120hz OpenGL 2D presentation of 3D objects.

Currently, the pico projector kit v2.0 only supports 60hz frame rate. Is there any plan to support 'soon-to-be-standard' 120hz frame rate? The reason for not using 120hz pattern rate is because, in many situation, the frame should be updated in real time depending on sensor read etc. Ideally, 120hz frame rate with many other higher freq pattern rate would be fantastic.

Alternatively, I recently read the light commander is capable of 500hz gray scale image transfer. If the same kind of API becomes available for pico projector, that would be one of the most significant and exciting improvement to the pico projector kit.

Thank you.

    Hi SG,

    Welcome to DLP&MEMS forum.

    Thank you for providing your valuable inputs on the DLP Kits. You made a valuable point we are making note of it.

    Pico Projector and DLP LightCommander(TM) are two different hardwares platforms and from h/w capability point of view the LightCommander(TM) can drive higher resolution and higher frame rate. Therefore it is not possible to do what is possible on DLP LightCommander(TM) platform on Picor Projector.

    I would like to provide more clarification on the 500Hz grayscale number you referred to DLP LightCommander(TM), the grayscale frame per second you are referring is for 'Static Images' i.e., the patterns need to be preloaded and then refreshed. The real-time 8-bit grayscale update for LightCommander(TM) is upto 180Hz. The non-real-time it is possible upto 716Hz.

    I want tell you that we are working on such requests to make them available in future development kits. I suggest you to continue following with DLP Kits. Thank you again for your valuable inputs.

    Regards,

    Sanjeev

    Thank you for your clarification. 180Hz still sounds very good. But it is sad to hear that it is not possible in a pico projector.

    For wide application possibility (including recent 3D development), it looks like then the best solution is to implement 120hz DVI data transfer. Pico projector's resolution is not as high as 1080p, and therefore the only barrier is probably hardware-level upgrade of the data transfer unit of the pico projector, I guess.

    Anyway, I hope I can see a 120Hz pico project asap.

    Thanks for your answer.
