Abstract
One object of the invention is to provide a display device that can display an image which causes a viewer less strain associated with viewing and gives a viewer a sense of great depth and an electronic device for enjoying the image. The present inventors have focused on a sense of depth obtained by monocular viewing and have conceived a display device in which pixels each include a light-emitting module capable of emitting light having a spectral line half-width of less than or equal to 60 nm in a response time of less than or equal to 100 μs and are provided at a resolution of higher than or equal to 80 ppi; the NTSC ratio is higher than or equal to 80%; and the contrast ratio is higher than or equal to 500.
Claims26
A display device comprising:
- pixels each including a light-emitting module capable of emitting light having a spectral line half-width of less than or equal to 60 nm, the pixels being provided at a resolution of higher than or equal to 80 ppi;
- and
- an image processing device transmitted an image signal, the image processing device comprising:
- a noise removing portion configured to remove noise from the image signal;
- a pixel-to-pixel complementary portion configured to complement data to the image signal when the resolution is up-converted;
- a tone correction portion configured to correct color tone of the image signal;
- and
- a complementary frame generating portion configured to generate an image of an frame when increasing frame frequency,
- wherein the display device has a NTSC ratio of higher than or equal to 80% and a contrast ratio of higher than or equal to 500.
