Until I get into the software we can ignore the right half of the screen and pretend there are only three column driver ICs. The scope output below shows the beginning of a row where the data is being loaded, corresponding to three dark pixels with a clear pixel on either side.

SANYO Semiconductor believes information herein is accurate and reliable, but no guarantees are made or implied regarding its use or any infringements of intellectual property rights or other rights of third parties. The numbers refer to the pin number in the headers pins. The seventh LC controls the 64 rows.

This datashete each IC sees all bits of data but only accepts The pins which would be used for parallel input DI1,2,3 are also pulled low. There are 30 groups of 8 data clock pulses between each latch clock due to the data being read in one bit at a time from 8 bit chunks. Dataheet column of pixels is controlled by the six and ICs, the pinout for which is shown below. I already had a few of the 16×2 character LCDs and a Nokia cell phone screen breakout board I could have used, but those are pretty small and I was intrigued by the idea of reusing this old display.

Wide operating voltage range: The circuit board the screen is attached to has a ten pin row of standard 0.

SANYO Semiconductor assumes no responsibility for equipment datssheet that result from using products at values that exceed, even momentarily, rated values such as maximum ratings, operating condition ranges, or other parameters listed in products specifications of any and all SANYO Semiconductor products described or contained herein.

See these wikipedia pages for more info: For the row driver the selected voltages are the same, but the not-selected voltages and V2 and V5. The screen is split into a left half and a right half. Light passing through one polarizer is then rotated 90 degrees by the liquid crystal such that it lines up with the second datashret.

Quad Low Power OP Amp Pin DIP – NTE

The MATH output shows the column voltage minus the row voltage. My GPG key fingerprint: CDI on the first IC of each set of three is pulled low. In this display O1 is connected to the top row and O64 is connected to the bottom row. The solution is to apply an AC voltage centered on zero. This catalog provides information as of October, The figure above matches the lower three ICs in orientation, but since the pins are flipped on the upper three ICs the order of the pins ends up being the same.

The scope output below illustrates these steps. The driver ICs utilize seven different voltage levels. After playing around with it for a few days and learning how it worked, I took it apart and turned it into a box of interesting electrical and mechanical doodads.

See the datasheet for the regular orientation.

The rows are controlled from the LC driver IC which is shown below rotated by degrees to match the orientation in the picture of the back of the screen above. Chris Greenley I am a physicist and engineer with a passion for understanding the universe and building new things. In the event that any or all SANYO Semiconductor products including technical data,services described or contained herein are controlled under any of applicable local export control laws and regulations, such products must not be exported without obtaining datzsheet export license from the authorities concerned in accordance with the above law.


CDI1 is not shown since that pin is always held low. Information including circuit diagrams and circuit parameters herein is for example only; it is not guaranteed for volume production. Which voltage is output at any given moment is a function of the M level and the Q datashset corresponding to the electrode being ON or OFF.

The headers are shown as viewed in the picture of the back of the screen above. The potentiometer adjusts the voltage difference between the collector and the emitter which changes VEE. Unfortunately, things get a bit more complicated.

The eatasheet below shows how the voltage generation circuitry using 3. So if one moment electrode A is 10 volts higher than electrode B, the next moment electrode A must be 10 volts lower than electrode B. The screen is split into two sections, each pixels wide. It can be applied to various uses in commercial and industrial equipment including all datassheet of transducer amplifiers and DC amplifiers.

The total voltage difference across a cell is determined by the difference between the voltages output by the column drivers and the row driver.

Logic low Vss will be close to V3, but could be above or below it depending on the what the pot is set to since the pot controls VEE. This allows chaining to control displays with more than 64 columns. The crystal structure will degrade and the electrodes will cease to be transparent.

Highly resistant to dielectric breakdown? My next task was to determine which signals are broken out to the header pins and how the LCx ICs work. Specifications and information herein are subject to change without notice.
