## **3 ELECTRICAL SPECIFICATION** 

## _**3.1 ABSOLUTE MAXIMUM RATINGS**_ 

|**Item**|**Symbol**|**Condition**|**Min**|**Max**|**Unit**|**Note**|
|---|---|---|---|---|---|---|
|Power Supply Voltage|IOVCC, VCI|Ta=25˚C|-0.3|4.6|V||
|Operating Temperature|TOP||-20|70|°C|1|
|Storage Temperature|TST||-30|80|°C|1,2,3|



- Note 1. 90 % RH Max for Ta<50 °C, and 60% RH for Ta≥50°C. 

- Note 2. In case of below 0°C, the response time of liquid crystal (LC) becomes slower and the colour of panel becomes darker than normal one. Level of retardation depends on temperature, because of LC's characteristic. 

- Note 3. Only operation is guaranteed at operating temperature. Contrast, response time, another display quality are evaluated at +25°C.

## _**3.7 POWER SEQUENCE**_ 

IOVCC and VCI can be applied in any order. VCI and IOVCC can be powered down in any order. 

During power off, if LCD is in the Sleep Out mode, VCI and IOVCC must be powered down minimum 120msec after RESET has been released. 

During power off, if LCD is in the Sleep In mode, IOVCC or VCI can be powered down minimum 0msec after RESET has been released. 

CS can be applied at any timing or can be permanently grounded. RESET has priority over CS. Note 1: There will be no damage to the display module if the power sequences are not met. Note 2: There will be no abnormal visible effects on the display panel during the Power On/Off Sequences. 

Note 3: There will be no abnormal visible effects on the display between end of Power On Sequence and before receiving Sleep Out command. Also between receiving Sleep In command and Power Off Sequence. 

Note 4: If RESET line is not held stable by host during Power On Sequence as defined in Sections 3.7.1 and 3.7.2, then it will be necessary to apply a Hardware Reset (RESET) after Host Power On Sequence is complete to ensure correct operation. Otherwise function is not guaranteed. 

## **3.7.1 Case 1 – RESET line is held High or Unstable by Host at Power ON** 

If RESET (RESX) line is held High or unstable by the host during Power On, then a Hardware Reset must be applied after both VCI and IOVCC have been applied – otherwise correct functionality is not guaranteed. There is no timing restriction upon this hardware reset. 

trPWRESX1 is applied to RESET (RESX) falling in the Sleep Out Mode trPWRESX2 is applied to RESET (RESX) falling in the Sleep In Mode 

Product No. DMT028QVNTNT0S-1A REV. 1.1 Page 14 / 27 

DENSITRON TECHNOLOGIES Ltd. – PROPRIETARY DATA – ALL RIGHTS RESERVED 

## **3.7.2 Case 2 – RESET line is held Low by Host at Power ON** 

If RESET (RESX) line is held Low (and stable) by the host during Power On, then the RESET must be held low for minimum 10μsec after both VCI and IOVCC have been applied. 

trPWRESX1 is applied to RESET (RESX) falling in the Sleep Out Mode trPWRESX2 is applied to RESET (RESX) falling in the Sleep In Mode 

## **3.7.3 Uncontrolled Power Off** 

The uncontrolled power off means a situation when e.g. there is removed a battery without the controlled power off sequence. There will not be any damages for the display module or the display module will not cause any damages for the host or lines of the interface. At an uncontrolled power off event, ILI9341 will force the display to blank and will not be any abnormal visible effects within 1 second on the display and remains blank until “Power On Sequence” actives. 

For other settings and details please refer to ILI9341 data sheet.

- This figure is given as a reference purpose only, and not a guarantee. 

- This figure is estimated for an LED operating alone. The performance of an LED may differ when assembled as a monitor together with a TFT panel due to different environmental temperature. 

- Estimated lifetime could vary on a different temperature and usually higher temperature could reduce the life significantly.

Any unit with illegible / wrong / double or no marking / label shall be rejected. 

## _**6.2 DEALING WITH CUSTOMER COMPLAINTS**_ 

## **6.2.1 Non-conforming analysis** 

Purchaser should supply Densitron with detailed data of non-conforming sample. After accepting it, Densitron should complete the analysis in two weeks from receiving the sample. 

If the analysis cannot be completed on time, Densitron must inform the purchaser. 

## **6.2.2 Handling of non-conforming displays** 

If any non-conforming displays are found during customer acceptance inspection which Densitron is clearly responsible for, return them to Densitron. 

Both Densitron and customer should analyse the reason and discuss the handling of nonconforming displays when the reason is not clear. 

Equally, both sides should discuss and come to agreement for issues pertaining to modification of Densitron quality assurance standard.

## **8 HANDLING PRECAUTIONS** 

## _**Safety**_ 

If the LCD panel breaks, be careful not to get the liquid crystal fluid in your mouth or in your eyes. If the liquid crystal touches your skin or clothes, wash it off immediately using soap and plenty of water. 

## _**Mounting and Design**_ 

Place a transparent plate (e.g. acrylic, polycarbonate or glass) on the display surface to protect the display from external pressure. Leave a small gap between the transparent plate and the display surface. 

When assembling with a zebra connector, clean the surface of the pads with alcohol and keep the surrounding air very clean. 

Design the system so that no input signal is given unless the power supply voltage is applied. 

## _**Caution during LCD cleaning**_ 

Lightly wipe the display surface with a soft cloth soaked with Isopropyl alcohol, Ethyl alcohol or Trichlorotriflorothane. 

Do not wipe the display surface with dry or hard materials that will damage the polariser surface. Do not use aromatic solvents (toluene and xylene), or ketonic solvents (ketone and acetone). 

## _**Caution against static charge**_ 

As the display uses C-MOS LSI drivers, connect any unused input terminal to VDD or VSS. Do not input any signals before power is turned on. Also, ground your body, work/assembly table and assembly equipment to protect against static electricity. 

## _**Packaging**_ 

Displays use LCD elements, and must be treated as such. Avoid strong shock and drop from a height. To prevent displays from degradation, do not operate or store them exposed directly to sunshine or high temperature/humidity. 

## _**Caution during operation**_ 

It is indispensable to drive the display within the specified voltage limit since excessive voltage shortens its life. Direct current causes an electrochemical reaction with remarkable deterioration of the display quality. Give careful consideration to prevent direct current during ON/OFF timing and during operation. Response time is extremely delayed at temperatures lower than the operating temperature range while, at high temperatures, displays become dark. However, this phenomenon is reversible and does not mean a malfunction or a display that has been permanently damaged. If the display area is pushed on hard during operation, some graphics will be abnormally displayed but returns to a normal condition after turning off the display once. Even a small amount of condensation on the contact pads (terminals) can cause an electro-chemical reaction which causes missing rows and columns. Give careful attention to avoid condensation. 

## _**Storage**_ 

Store the display in a dark place where the temperature is 25°C ± 10°C and the humidity below 50%RH. Store the display in a clean environment, free from dust, organic solvents and corrosive gases. 

Do not crash, shake or jolt the display (including accessories).
