The scope output dataseet illustrates these steps. Which voltage is output at any given moment is a function of the M level and the Q level corresponding to the electrode being ON or OFF. Effect of Chirality and Twisted nematic field effect. The three ICs controlling the left half get data from header pin 1 and the three ICs controlling the right half get data from header pin 2.

In this display O1 is connected to the top row and O64 is connected to the bottom row. The MATH output shows the column voltage minus the row voltage. For a pixel to be OFF clear the voltage difference between the electrodes is 1.

The crystal structure will degrade and the electrodes will cease to be transparent. Looking at the results of the difference between the row and column voltages, it is clear that the difference in voltage is large datasueet to darken the pixels in row 1 only for the time between the first and second latch clock pulses. After googling for the datasheets it turns out that one of the smaller ICs is a quad opamp LAN which provides the required voltages for driving the LCD lla6324n more on that later.

The driver ICs utilize seven different voltage levels. 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.

It is possible that these probabilistic failures could give rise to accidents or events that could endanger human lives, that could give rise to smoke or fire, or that could cause damage to other property. A few months ago L6324n popped into Goodwill to see if they had any interesting electronics to take apart.

Highly resistant to dielectric breakdown? I am a physicist and engineer with a passion for understanding the universe and building new things. When designing equipment, adopt safety measures so that these kinds of accidents or events cannot occur.


In the event that any or all SANYO Semiconductor products including technical data,services described or contained herein are controlled under any of fatasheet local export dtaasheet laws and regulations, such products must not be exported without obtaining the export license from the authorities concerned in accordance with the above law.

The next output still shows the same signals, but with the la6324m realistic scenario where the rows are being activated one at a time while every pixel in every column is ON dark. Until I get into the software we can ignore the right half of the screen and pretend there are only three column driver ICs. Light la624n through one polarizer is then rotated 90 degrees by the liquid crystal such that it lines up with the second polarizer.

These four operational amplifiers are packaged in a single package. My next task was to determine which signals are broken out to the header pins and how the LCx ICs work.

Each column of pixels is controlled by the six and ICs, the pinout for which is shown below. The remaining 4 are created by the quad opamp IC. The seventh LC controls the 64 rows.

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.

SANYO Semiconductor assumes no responsibility for equipment failures 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.

The numbers refer to the pin number in the headers pins. 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. To verify symptoms and states that cannot be evaluated in an independent device, the customer should always evaluate and test devices mounted in the customer’s products or equipment. The total voltage difference across a cell is determined by the difference between the voltages output by the column drivers and the row driver.


See these wikipedia pages for more info: The following scope output shows the relationship between the data clock, latch clock and frame clock.

The circuit board the screen is attached to has a ten pin row of standard 0. This output shows the somewhat unrealistic, but helpfully illustrative, case where every row and every column are ON at all times. See the datasheet for the regular orientation.

Wide operating voltage range: I’m a current participant in the great post-grad job hunt. 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. The pins which would be used for parallel input DI1,2,3 are also pulled low. Specifications and information herein are subject to change without notice.

For the row driver the selected voltages are the same, but the not-selected voltages and V2 and V5. Breathing new life into a screen salvaged from a Smith Corona electric typewriter. Unfortunately, things get a bit more complicated.

Information including circuit diagrams and circuit parameters herein is for example only; it is not guaranteed for volume production. The solution is to apply an AC voltage centered on zero.

The adtasheet board has seven large ICs and two smaller ICs. My GPG key fingerprint: The voltages are all measured relative to logic low. Three are from header pins 7, 8 and, via the la63324n, pin 9.
