The Galaxy J7 has a 5.5-inch Super AMOLED display with a pixel resolution of 1280 x 720 pixels and a pixel density of around 267 PPI. The display is bright, has good viewing angles, offers vibrant color output and the sunlight visibility is also good.
Since it doesn’t have an ambient light sensor you have to adjust the brightness manually using the slider depending on the conditions. There is an outdoor mode option that increases the brightness for 15 minutes or until the screen is turned off.
