- In this video is exposed the electronics constituting a Gamma chip that we find in the TCON card of a TFT LCD TV as the reference AS15 and AS19. Here is detailed the difference between a classic gamma chip and those which are known as programmable. For the clarity of the presentation are recalled some basic principles in electronics as the voltage divider and operational amplifiers (opamp) especially in voltage follower configuration.
Thank you sir
Hi
Good explanation about GAMMA....i never see before like this ...thanks so much Sir.
What a amazing explanation. Thank you so much!
muito bom, parabens , otimo video, jorge carvalho, engenheiro de controle e automação.
Hi sir, good afternoon.
Is prescribed Text book for lcd LED full problems and solutions.
Give me the name of that book.
Books from this author: jestine Yong, kent Liew and Damon Morrow
@@elearningélectronique Thanks sir.
why horizonal lines in display appear
it can be a defect of the gate driver circuit
Superb explanation on gamma section
Never seen such good explanation.
You are too good sir
Thanks for making and sharing such a great wonderful video.

❤❤❤
👌🙏🙏🙏
Sooooo beautiful. You people are doing a great Job to the world. Thank you for sharing.
Thanx sir,nice job.
Your video Super.
I hope LCD LED TV will teach the whole theory.
Genious!
Hi! This was a great video exlpaining almost everything in detail. Except one point which I ve been searching for a long time. How is the pixel intensity of 8 bit (256 values) being arranged by 10 gamma voltage? Is there another extra DAC in between Gamma output and the TFT source? What is the algoritm, circuit behing that?
Yes, I’m asking this to myself too. Is a partial gamma correction sufficient to maintain properties of the lcd cell ? Or are programmable chips more efficient / complete giving a better quality and more durable screen ?
Thank you sir,from Philippines cebu
👏👏👏👏💪💪💪💪💪👍👍👍👍!!!!
Nice explanation sir🙏🙏👍
Very useful information
👍👍👍👍👍👍👍👍👍👍👍
U r best Sir
Thank you, I need more informations.
Please give new video.
it takes a little time but it's planned
