Taka wielkosc mozna latwo obliczyc znajac wymiaru panelu - szerokosc i rozdzielczosc w poziomie. I dzielac rozdzielczosc w poziomie przez szerokosc wyrazona w calach. A jak sie nie zna rozdzielczosci w pikselach, to liczba dzielac szerokosc przez rozmiar plamki i zaokraglaja do wartosci calkowitej.
To znalazlem
LCD native DPI : 72-96, 91, 110, 120,
rozmawialem z grafikiem i mowil, ze jego monitor ma rozdzielczosc w poziomie 72 DPI (19 lub 20" LCD)
A co z wyswietlaczami do komorek, malych telewizorow LCD, przenosnych odtwarzaczy DVD itp. Gdzie mozna znalezc pelna tabelke porownawcza wszystkich matryc LCD, dostepnych na rynku, stoowanych w sprzecie elektronicznym, video, photo, dvd, komputerowym .
Oczywiscie interesuje mni rozdzielczosc fabryczna, czyli punktow matrycy, a nie interpolowana programowo.
Taka mam tabelke
All LCD monitors are fixed resolution devices. LCD monitors use a matrix of cells so the pixels are in a fixed location and therefore define the native resolution of the monitor. What you are seeing is the spcers between the cells of the LCD. For example a typical 18" LCD monitor with a dot pitch of 0.2805mm and a horizontal viewable area of 359mm has a native resolution of 1280 in the horizontal direction. Math is simple,
359 divided by 0.2805 equals 1279.85 or 1280 if you account for the small rounding error. Same calculation can be made in the vertical direction. DPI can be caluclated as follows. Your 21" monitor most likly has a horizontals viewable area of 395mm or 15.6 inches. Divide the horizontal resolution by the viewable area = DPI. If you are running 1280 resolution 1280 / 15.6 = 82 DPI. An 18" LCD at 1280 x 1024 with aviewable area of 359mm or 14" same calcualtion, 1280 / 14 = 91 DPI.In this example the LCD has better DPI however it looks grainer due to the lower Dot pitch and the spacers used in LCD monitors.
i dalej
I've got an 18in flat panel monitor with screen res set at 1280 x 1024. This is the screen's "native resolution". Some displays & fonts are small for my eyes so I might increase DPI from 96 to 120.
i dalej Viewsonic 200 DPI
This 22.2-inch LCD panel being sold by Viewsonic uses the same panel developed and marketed by IBM last year. The difference is that IBM charged nearly $20,000 for its version; Viewsonic plans on selling this one for around $8,000. That's still pretty pricey -- what makes this panel so special?
Try 9.2 million pixels, for one thing. This 16x9 aspect panel has a native resolution of 3840x2400 pixels. That translates to roughly 200 dots per inch.
