I have a question regarding the minimum clock rates allowed on LVDS- based LCD display panels. Perhaps someone in the group has some expertise here.
I have HD data coming in at 30 frames per second. I have no place to store a full frame. The HD display panel requires a minimum clock rate of at least 50 MHz (which, according to the display data sheet, equates to about 50 frames per second). I'd like to drive it at about
36 MHz. Even if I had a frame buffer, the I/Os are not fast enough to drive the display at more than about 300 megabits per second (the LVDS is emulated with external resistors).Do you know if the minimum specified clock rate is the absolute minimum guaranteed clock frequency to guarantee that the display operates, or is it the minimum clock frequency to guarantee the display's specified response time? Will the display actually operate with a lower clock frequency. I know that I should ask this of the vendor, but unfortunately, there is little support for this display.
I have tested another vendor's LCD display at well below the data sheet specified frequency and it operated just fine.
Thanks in advance for any advice you might have.
