Grayscale Level Grayscale ngu ai hpe nsam madang (sh) gray scale ngu nna mung shamying ma ai, dai gaw nsam langai a nhtoi hpe tsun mayu ai. Digital display hpaji masa a matu, grayscale gaw nsam ni hpe madun na matu dawdan ya ai lam rai nga ai. Madung hku tsun ga nga yang, grayscale grau tsaw wa yang, madun da ai nsam ni grau sut su wa nna, sumla grau n-gun ja wa nna, sut su ai lam ni hpe tsun dan na matu loi wa ai. Grayscale level gaw madung hku nna system a A/D galai shai ai lam a bits jahpan hta madung nga ai. Teng sha nga yang, dai system a video galaw ai chip, memory, hte shapoi ai system ni gaw, dai hpe madi shadaw na matu, dai hte maren, bit jahpan hpe jaw ra ai. Mungdan kata na LED display ni hta madung hku nna 8-bit galaw ai ladat hpe lang ai, dai gaw 256 (28) madang na grayscale hpe lang ai. Tsun mayu ai gaw, nsam hpraw kaw nna hpraw du hkra nhtoi htoi ai n bung ai lam 256 nga ai. RGB a madung nsam masum hpe lang nna, nsam 256×256×256=16,777,216 hpe galaw lu ai. Dai gaw, masha law malawng tsun ai 16 megacolors re. Mungkan ting na brand display ni hta madung hku nna 10-bit processing system hpe jai lang ai, lachyum gaw 1024 madang na grayscale hpe lang ai, RGB madung nsam ni hpe nsam 1.07 billion hpe shapraw lu ai.
Grayscale gaw nsam ni a jahpan hpe dawdan ai hta dawdan ya ai lam rai tim, grau tsaw ai gaw grau kaja ai ngu ai masa n re. Langai, shinggyim masha a myi a resolution gaw shadawn sharam sha nga ai.

Grayscale Non-linear galai shai ai lam: Grayscale non-linear galai shai ai lam ngu ai gaw, grayscale data hpe empirical data (sh) nkau mi a arithmetic non-linear matut mahkai lam ni hte maren galai shai ai lam hpe tsun mayu ai rai nna, dai hpe madun dan ai screen de n jaw shi yang, galai shai ai lam hpe tsun mayu ai. LED ni gaw linear device re majaw, shanhte a madun ai atsam gaw, htunghking monitor ni a non-linear madun ai atsam hte shai ai. LED madun dan ai akyu gaw, grayscale madang ni hpe n sum hkra, htunghking hku na data source hte bung hkra galaw na matu, LED madun dan ai ladat a hpang na daw ni hta, grayscale data hpe non-linear galai shai ai lam hpe, madung hku nna galaw ai. Galai shai ai data hta bit ni law wa ai (grayscale data n sum mat hkra). 4096-madang (sh) 16384-madang grayscale (sh) dai hta jan ai hpe mungdan kata na hkang zing ai ladat garan jaw ai ni nkau mi tsun ai gaw, non-linear galai shai ai lam . 4096 madang ni ngut ai hpang na grayscale shara a kaba ai hpe tsun ai rai nna, non-linear galai shai ai lam . 4096 madang ni hta 8-linear galai shai ai lam hpe jai lang ai shaloi, 8-linear galai shai ai lam hpe jai lang ai. 16384 madang ni hta 8-bit hpe lang nna 16384 du hkra lang ai. 16-bit n-linear galai shai ai hpaji masa hpe jai lang ai. 8-bit source hpe lang nna n-linear galai shai ai lam gaw 8-bit source hta grau kaba ai grayscale shara hpe teng sha lu la na re.
