Tam sim no peb pom e-pov tseg ntau heev, thiab qee qhov ntawm lawv yog PCBs uas tau muab pov tseg ncaj qha vim tias lawv ua haujlwm tsis zoo. Tam sim no tshwj xeeb hais txog LCD zaub, thaum tsim cov duab no ntau qhov yuam kev tuaj yeem tshwm sim uas tsis paub txog qhov muag liab qab.
thaum khaws cia hauv qhov pom lawv poob dub qhov no yog ib txoj hauv kev kom pom cov laug puas. yog li hnub no peb yuav ua lub teeb nrog cov PCBs no. Lawv saib zoo nkauj tiag tiag tom qab ua tiav.
Khoom siv
1. PCBs puas (LCD board)
2. translucent acrylic ntawv
3. 2 tus pin txuas
4. 3.7 v roj teeb (yeem fais fab mov)
Kauj Ruam 1: Xaiv Cov Phiaj Xwm Puas
1. koj tsuas yog xav pom lub LCD thiab koj yuav pom qhov xim dub yog tias pawg thawj coj saib puas. thiab qhov ntawd yog txhua yam koj xav tau.
2. dismantle qhov screen thiab coj lub rooj tsavxwm.
Kauj Ruam 2: Ua: Cubical Tawm ntawm PCB
1. siv tus pin perpendicular ua qhov sib txuas rau LED tus pin thiab hauv av.
2. ua lub voos xwmfab nrog 4 PCBs thiab tawm ob lub ntsej muag sib luag rau cov tsom iav.
3. muab kev txuas rau 2 tus pin poj niam lub qhov (socket).
Kauj Ruam 3: Xeem 1
txuas lub roj teeb thiab pom tias txhua lub teeb muaj qhov sib npaug sib npaug.
Kauj Ruam 4: Ua: Reflector
1. kos tawm ob lub xwmfab ntawm qhov sib npaug uas tuaj yeem nkag mus rau hauv lub voos xwmfab.
2. txiav tawm cov plaub fab thiab xa lawv.
3. lo daim ntawv kom txog thaum kawg thiab koj tau ua lub teeb.
Kauj Ruam 5: Xeem 2
txuas lub roj teeb thiab saib qhov tshwm sim.
Kauj Ruam 6: Teeb Roj Teeb
lo lub roj teeb nrog daim kab xev ob txoj hauv kev thiab ua tiav.
Kauj ruam 7: Thaum kawg
