LG fremviser quad-HD smartphone-skærm

Den passer jo PRÆCIST til Oculus Rift! De startede også med en 5,6" skærm, men var nødt til at skifte til en 7" i sidste øjeblik, for at kunne få nok paneler. Og den høje opløsning er kærkommen, og på ingen måde for meget i den situation.

Under normale omstændigheder er 300 ppi maksimum for, hvornår et øje kan skelne de enkelte pixels fra hinanden, jvf Wikipedia.

Ifølge den her kilde kan normalt seende skelne op til 600 ppi.

Wikipedia skrev:

Some observations have indicated that the unaided human eye can generally not differentiate detail beyond 300 PPI;[4] however, this figure depends both on the distance between viewer and image, and the viewer’s visual acuity. The human eye also responds differently to bright, evenly lit and interactive display, than prints on paper.

De kan vel egentlig nøjes med en skærm på 2560x720 pixels for at opnå 1280x720 på hvert øje - så er prisen vel det halve :)

A “normal” human eye is considered to have standard visual acuity or 20/20 vision. This means that a 20/20 eye can discriminate two lines or two pixels separated by 1 arcminute (1/60 degree).


Theoretically the limit of retinal resolution, say the ability to distinguish patterns of alternating black and white lines is approximately 120pixels/degree in an optimal, healthy eye with no optical abnormalities

det bliver til 287 PPi ved 30,48 cm afstand til øjet

Dr. Colenbrander also emphasizes that, contrary to popular belief, 20/20 is not actually normal or average, let alone perfect, acuity. Snellen, he says, established it is a reference standard. Normal acuity in healthy adults is one or two lines better. Average acuity in a population sample does not drop to the 20/20 level until age 60 or 70. This explains the existence of the two lines smaller than 20/20: 20/15 and 20/10.

The Range of normal vision covers 20/12.5 to 20/25. Note that the visual acuity scale is not truncated at 20/20. 20/20 is a reference standard; it is not perfect vision. Snellen choose this standard so that all healthy young adults exceed it. This range allows reading of newsprint (1 M) at 80 to 160 cm. Since normal reading is at about 40 cm, there is a very comfortable reserve.

Ethvert skridt mod denne opløsning er en absolut fordel.

teknologien på dpi skal bare nå et kritisk punkt, hvor dpi'en bliver så højt, at man kan skalerer et billed, uden at man kan se at billedet er interpoleret. vi er ikke nået dertil endnu

Slet ingen der vil se hvad der er bag skærmen ?

Bag skærmen? Det er jo ikke en telefon de fremviser, kun en skærm...
