{906} Understanding dot matrix LCD || LCD explained

in this video number {906} Understanding dot matrix LCD || Find LCD module size / LCD explained. i explained what is lcd, how a lcd works, and how to determine dot matrix lcd display size. i checked 16080 160x80 lcd module, it is using LC7981 lcd controller, lc7940 ic is used dot matrix columns, LC79430 is using as a driver for rows.

So nice of you

[@escheytt9326]

Very informative video. Would be great to expand this topic to a color LCD's functioning. Thank you and best regards,

[@ArneChristianRosenfeldt]

Color LCD has a a color Filter with lines of RGB glued to them. The backlight then can be white instead of green. Horizontal resolution goes down by a factor of three. Theoretically, the polarisers could be optimized for wavelength when using twisted nematic. I think for in plane switching by TFTs, it does not matter.

I am still confused about the different driver chips. I understand that I need those chips with 80 pins to connect to the LCD. These chips have a small number of input pins to simulate a CRT or Laser scanner. serial data goes in and fills the screen.
Now I wonder if I could remove the memory. For a gameboy or Sega game gear ( even if emulated ) I want to send the lines just in time.
For framebuffer based Atari Lynx it would be great if one could include a small FPGA to compensate the previous frame ( double / tripple buffering ) to reduce lag. I imagine 480 fps to implement pulse width modulation for the delta value. For passive displays, cross talk needs to be compensated.

[@HaseebElectronics]

good morning
yes scanner or T-Con controller receives 8 lines LVDS signals (4 pairs) and expands it into X-Y drives for panel array (depending on display type)
as the answer of the second part of your question, i have no comment. because i never tried or never attempted to do in this way.

[@turkialshehri9762]

Hasseb I need help please,I am planing to build grid on solar inverter without batteries as that avalible in the market.I found alots of usiful channels to do wit arduino and EG 8010 ,but what is most diffuiclt part is that the synchronous of phases and vlotage.Could u help if u know ICs can do this job for me .Thanks

[@gartheligon140]

Thank you for your information.
Do each pixel have a + and - ?

[@ArneChristianRosenfeldt]

Yeah, top and bottom electrode made of Indium Tin Oxyde . On better LCDs there is this black matrix which probably made of real metal. ITO is just good enough for current from the edge of the pixel to the center.
In plane switching uses transistors ( on glass ? ) and the metal electrodes between the pixels. So left and right electrode. The transistor also has two inputs

[@muhsen61]

dear haseeb .please can u give us som explination about the cpu / Pic 18f6740 ??? thsnk you

[@warunakumara7671]

SIR THANK U FOR THE VIDEO IAM WARUNA FROM SRILANKA , CAN U PLZ DO A VIDEO SERIES THAT EXPLAIN HOW TO DRIVE A DOTMATRIX LCD USING PIC MICROCONTROLLER , THANK U SIR

[@ArneChristianRosenfeldt]

There are like a ton of videos. This is the only one which explains bare LCD.

My name Omar pleasa I want to know lcd / led tv how it works

[@ArneChristianRosenfeldt]

When you look at dismantled TVs , you find many driver chips along the edges. 80 lines are not enough . So use 10 chips .
