AB The easy access to electronic devices for users has resulted in the development of a vastrange of programs and applications for visual evaluation and diagnosis that can be downloaded toany device. Some of them are based on tasks and stimuli that depend on luminance. The aim of thepresent study was to evaluate differences in luminance reproduction between electronic devices andtheir implications for contrast reproduction. A total of 20 Galaxy Tab A devices with 8-bit graphicsprocessing units were evaluated. Characterization of every screen was performed obtaining theresponse curve for the achromatic stimulus. Mean, maximum and minimum luminance, standarddeviation and coefficient of variation were obtained to assess differences between devices. Variationof luminance with increasing digital level was observed in all devices following a gamma distribution.Comparison between devices for mean results showed that some of them differed by as much as45 cd/m2. The coefficient of variation varied from ~5 to 9%. Mean percentage of differences inluminance between devices reached 30%. In conclusion, differences in luminance reproductionbetween devices were present, even considering devices from the same manufacturing batch. Itcannot be assumed that the characterization of one device can be extrapolated to other devices.Every device used for research purposes should be individually characterized to ensure the correctreproduction. For clinical purposes, limitations should be considered by visual specialists.
