NHD-7.0-800480EF-ATXV#-CTP very low brightness
« on: February 17, 2016, 01:43:41 AM »
We have bought both 7" displays with capacitive touch screen. NHD-7.0-800480EF-ATXV#-CTP needs 9.6V/160mA for backlight panel. The ATXL version needs 16V/60mA. We have managed get the backlight working for both displays. Both voltage and current for backlight panels are in correct levels. Without any data, backlight panel brightness is good enough. But the level of the brightness with some data on the display is very low. Can you please provide some photo of that display with backlight panel at the maximum level? We suspect, that display is not sun-readable, is it right? Viewing in 75 degrees, the display seems to be brighter, but we do not need that, we prefer front viewing.

Hi Marsaf,

Correct, NHD-7.0-800480EF-ATXV#-CTP and NHD-7.0-800480EF-ATXL#-CTP are not sun-readable displays.

NHD-7.0-800480EF-ATXV#-CTP will have the greatest viewing angles 75deg (MVA) and be the brightest out of our current 7.0" CTP line-up (290 cd/m2).

We will be introducing sunlight-readable TFT's in the up coming months.  These new displays have brightness levels and features that allow for excellent viewing quality even in direct sunlight conditions.

In the mean time feel free to check out our new 4.3" Sunlight Readable TFT with capacitive touch.
