Apr 12, 2022
Usually the working temperature of the backlight is -20-70 degrees, and the drawings before proofing will also be clearly marked. Yesterday, when a customer was doing a high temperature test, the temperature was 45 degrees, and the backlight went out and the picture was cooled to about 35 degrees. It is working normally again. It is suspected that our backlight cannot withstand high temperature. Later, after a series of tests, it is their driver chip problem, which is an inferior fake.
Lub teeb emission ntawm lub backlight nyob ntawm lub teeb hlaws. Qhov kub thiab txias tsis kam ntawm LED teeb hlaws yog 110 degrees lossis siab dua. Thaum lub ntsuas kub nce mus txog qhov ntsuas kub uas tuaj yeem ua rau lub teeb hlaws puas, lub teeb hlaws yuav rov qab tsis tau tom qab nws tawg, thiab nws yuav tsis zoo li qub. Tom qab ua haujlwm, vim li cas koj thiaj hais tias qhov ua haujlwm kub ntawm lub backlight yog -20-70 degrees? Ua ntej, qhov kub thiab txias tsis kam ntawm lub teeb hlaws yog li 60 degrees. Qhov kub thiab txias dua, nws lub neej luv dua. Qhov thib ob, cov khoom siv acrylic yog nws yuav soften ntawm li 90 degrees, thiaj li yuav muaj thermal expansion thiab contraction, thiab lub thinner lub nro, nws yog yooj yim dua deform, vim hais tias teem ib tug tsim nyog ua hauj lwm kub ntau yam, thiaj li hais tias lub backlight muaj peev xwm. yuav siv sij hawm ntev dua.
