|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. 

## 3.1.2 PCT

**Note 4.** If used beyond the absolute maximum ratings, FT5926QSM may be permanently damaged. It is strongly recommended that the device be used within the electrical characteristics in normal operations. If exposed to the condition not within the electrical characteristics, it may affect the reliability of the device.

|Forward Current|IF|Ta=25 °C|60|75|‐|mA|
|Forward Voltage|VF|Ta= 25°C||25.6||V|
|LED life time|Hr||||50k|hour|



Note: 

- The lifetime of the LED is defined as a period till the brightness of the LED decreases to the half of its initial value. 

- 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.

## 6.1.7 Classification of Defects 

Visual defects (except no or wrong label) are treated as minor defects, while electrical defects are treated as major defects. 

Two minor defects are equal to one major defect in lot sampling inspection. 

## 6.1.8 Identification / marking criteria 

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 non‐ conforming 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.

## 8.0 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).
