Absolute Maximum Ratings

Cautions:
Any Stresses exceeding the Absolute Maximum Ratings may cause substantial damage to the device. Functional operation of this device at other conditions beyond those listed in the specification is not implied, and prolonged exposure to extreme conditions may affect device reliability

Electrical Characteristics

LED Backlight Circuit Characteristics

Cautions:
Exceeding the recommended driving current could cause substantial damage to the backlight and shorten its lifetime.

AC Characteristics

 8080 Mode

Note:

1. Ts = System clock period
2. t4min = 2Ts + 5
3. t11max = 1Ts + 7 (for 5.0V)
4. t12min = 1Ts (for a read cycle followed by a read or write cycle) = 2Ts + 2 (for a write cycle followed by a write cycle) = 5Ts + 2 (for a write cycle followed by a read cycle)
5. t13max = 4Ts + 2
6. Input signal rise/fall time should be less than 4.5ns
7. For details, please see the S1D13700 data sheet

Reset Timing

note:

1. A delay is required after exiting power save mode. Writing the SYSTEM SET command will exit power save mode and start the internal oscillator.
2. It requires a reset pulse after power-on to re-initialize its internal state.

Function Specifications

Adjusting the Display Contrast
A variable resistor must be connected to the LCD module to provide a reference to V0. Adjusting the VR will result a change of LCD contrast. The recommended value of VR is 25k to 50k

Resetting the LCD module
The LCD module should be initialized by a hardware reset, using the/RES terminal.

Display Pixel Map

Note:

1. Based on the top view of the LCD module, the 1, 1 (x, y) pixel is the upper-left pixel; the 320, 240 (x, y) pixel is the lower-right pixel.
2. For the details of memory mapping, please refer to the S1D137009 datasheet.

Command Summary

Note:
For details, please refer to the S1D13700 datasheet.

Initialization Setting Example
The following settings should be issued tothe  LCD module after a hardware reset. (Example could be adjusted if necessary.)

Note:
For details, please refer to the S1D13709 datasheet.

Design and Handling Precaution

1. The LCD panel is made of glass. Any mechanical shock (eg, dropping from a high place) will damage the LCD module.
2. Do not add excessive force on the surface of the display, which may cause the Display color to change abnormally.
3. The polarizer on the LCD is easily scratched. If possible, do not remove the LCD protective film until the last step of installation.
4. Never attempt to disassemble or rework the LCD module.
5. Only Clean the LCD with Isopropyl Alcohol or Ethyl Alcohol. Other solvents (eg, water) may damage the LCD.
6. When mounting the LCD module, make sure that it is free from twisting, warping, and distortion.
7. Ensure to provide enough space (with a cushion) between the case and LCD panel to prevent external force from being added to it, or it may cause damage to the LCD or degrade the display result.
8. Only hold the LCD module by its side. Never hold the LCD module by add force on the heat seal or TAB.
9. Never add force to the component of the LCD module. It may cause invisible damage or a degradation of the reliability.The
10. LCD module could be easily damaged by static electricity. Be careful to maintain an optimum anti-static work environment to protect the LCD module.
11. When peeling off the protective film from the LCD, static charge may cause an abnormal display pattern. It is normal and will resume to normal in a short while.
12. Take care and prevent getting hurt by the LCD panel’s sharp edge.
13. Never operate the LCD module exceed the absolute maximum ratings.
14. Keep the signal line as short as possible to prevent a noisy signal from affecting to LCD module.
15. Never apply a signal to the LCD module without a power supply.The
16. IC chip (eg, TAB or COG) is sensitive to the light. A strong lighting environment could cause a malfunction. Light sealing structure casing is recommended.
17. LCD module reliability may be reduced by temperature shock.
18. When storing the LCD module, avoid exposure to direct sunlight, high humidity, high temperature, or low temperature. They may damage or degrade the LCD module
