COMMON VOLTAGES OF COF IC |led tv panel cof ic
What is COF IC: - COF IC is the main part of the all type of LCD LED panel because main board and panel getting connected through the COF ic and all the signals goes in to the panel with the help of COF IC. I will mostly focus on the How to download COF ic datasheet, Common voltages of the COF IC, if you can not get the COF ic datasheet then what you can do and how to make datasheet COF IC datasheet yourself.
How to get COF IC Datasheet: I would like to tell all of you, you can't get the COF IC datasheet from the internet most time, so if you want to get COF IC datasheet immediately then you will contact with your friends or any other LCD LED TV technician or you can contact with YouTube who provide COF IC datasheet free of cost or you can buy COF IC datasheet from the YouTube who want to cell their experience and hardworking things for the few donations.
COMMON VOLTAGES OF COF IC DATASHEET: So guys here I'm going to discuss about the main and common voltage of COF IC which is use in all LCD LED TV panels. So lets get started
(1) VGH voltage (20v to 30v) This is the most common voltage of any kind of panel like LCD panel or LED panel and if this voltage is getting weak and missing the you will get NO PICTURE problem in your panel.
(2) VGL (-5v to -12v) VGL voltage also most common voltage for the panel. SLOW MOTION PICTURE will show in the panel if this voltage do not produce and can not getting in the panel COF IC.
(4) DVDD (3.3v) This voltage have many names like VDD, VLOGL, CV33V, etc. So if this voltage is missing in the panel COF IC then main problem we get in the panel that is SLOW MOTION PICTURE.
(5) AVDD (12v to 20v) similarly this voltage have more name like VDDA, VSA,etc. If this voltage do not produce in the panel through the COF IC then the msin problem is getting in the panel is NO PICTURE.
(6) CKV1, CKVB1, CKV2, CKV2 these are not voltages these are signals track which are used for control the picture stability and double imaging so if you get DOUBLE IMAGE problem in the any panel the cut these type of track lines your DOUBLE IMAGE problem will be fix and make graphic properly
