The tested LCD panel is not used in any other tests. * The LCD panel is tested in circumstances in which there is no condensation. * The tested LCD is inspected after 2 hours of storage at room temperature and room humidity after each test is finished. AZ DISPLAYS 13 ATM0280D11(AZ DISPLAYS) TFT MODULE VER1.0 5.1 Handling Precautions of panel *As LCD module is glass product of precision processing and special treatment, it is vulnerable enough to have chips and cracks easily. And especially edges should be protected from shocks. If the liquid crystals in LCD flows out when the product is broken pay most attention to that you do not put the liquid crystal into your eyes and mouth. If the liquid crystal touches your hand, skin, or clothing, wash it away with soap and water immediately and completely. *The polarizer on LCD is soft and easily scratched. If the surface is stained, use soft dry cloth and wipe gently. If the surface is heavily stained, use the following solvents: 1, Isopropyl alcohol. 2, Ethyl alcohol. Other solvents may damage the polarizer. Especially, do not use water, ketone and aromatic solvents. *Do not give any pressure to the surface of LCD, and do not give excessive stresses to the side of LCD module. It may cause a distortion of color on the LCD. *As LCD module uses CMOS devices, it is very sensitive to static electricity. *Touching the IC of LCD module may cause abnormal display that cannot recover. Do not touch the IC of LCD module. *If the logic circuit power is OFF, do not apply the input signals. *Be sure to ground the body when handling the LCD module. *Tools required for assembly, such as soldering irons, must be properly grounded. *To prevent destruction of the elements by static electricity be careful to maintain an optimum work environment. *Do not forcibly pull or bend the I/O cable. *Do not disassemble or process the LCD module. *NC terminal should be open. Do not connect anything. *To reduce the amount of static electricity generated, do not conduct assembly and other work under dry conditions. *The LCD module is coated with a film to protect the display surface. Take care when peeling off this protective film since static electricity may be charged. *Please handle carefully, because the glass has a sharp edge. 5.2 Storage Precautions *Take care to minimize corrosion of the electrode. Moisture condensation on a current flow in a high humidity environment accelerates corrosion of the electrode. *When storing the LCD module, avoid exposure to direct sunlight or to the light of fluorescent lamps. Keep the LCD module in bags designed to prevent static electricity charging under low temperature/normal humidity conditions (avoid high temperature/ high humidity and low temperature below 0℃). 5.3 Design Precautions *The absolute maximum ratings represent the rated value beyond which LCD module can not exceed. When the LCD module is used in excess of this fated value, their operating characteristics may be adversely affected. To prevent the occurrence of erroneous operation caused by the noise, attention must be paid to satisfy VIL, VIH specification values, including taking the precaution of using signal cables that are short. *The liquid crystal display exhibits temperature dependency characteristics. Since recognition of the display becomes difficult when the LCD is used out of its designated operating temperature range, be sure to use the LCD within this range. * We recommend that power supply lines (VDD, VEE) have over-current protection line. (Fuse etc.) *Sufficiently notice the mutual noise interference occurred by peripheral devices. *To cope with EMI, take measure basically on outputting side. *When fixing LCD module, which is consisted of glass panel, TCP fixes it at plastic case side. In case PCB is fixed, there is the possibility that the disconnection is occurred by somewhat stress. *When mounting the LCD module, make sure that it is free of twisting, warping and distortion. Distortion has great influence upon display quality. Also keep the shiftiness enough regarding the outer case. AZ DISPLAYS 14 ATM0280D11(AZ DISPLAYS) TFT MODULE VER1.0 5.4 Other *Liquid crystal solidify under low temperatures (below the storage temperature range) leading to defective orientation or the generation of air bubbles. Air bubbles may also be generated if the LCD module is subjected to a strong shock at a low temperature. *If the LCD module has been operating for a long time showing the same display patterns, the display patterns may remain on the screen as ghost images and a slight contract irregularity may also appear. A normal operating status can be regained by suspending use for some time it should be noted that this phenomenon does not adversely affect performance reliability. *To minimize the performance degradation of the LCD modules resulting from destruction caused sections by static electricity, etc, take care to avoid touching the following sections when handing the module. ①Terminal electrode sections, ②Part of pattern wiring on FPC, etc. AZ DISPLAYS 15 3.4 AZ DISPLAYS (25) 43.2(LCD A/A) *50±0.2(OUTLINE) 0.15 (31.5) 2.7 40 0.3± 0.05 4.5±0.3 20.5± 0.1 21± 0.5 PI Stiffener *2.8±0.15 With FPC&B/L FPC ALL-0.8 *2.65(MAX) 2-R 0.2 40 1 4±0.3 Single layer *3 -? 0. 95 ± 0. *0±0.1 BLU CIRCUIT DIAGRAM Insulation tape& Solder High T:0.35mm *49.05±0.1 1 *0.475 ± 0.1 Single layer 20±0.5 1 Single layer PLCK HSYNC 3 4 0.5± 0.1 VCC(2.8V) GND GND GND GND GND GND GND 34 35 36 37 38 39 40 NC 33 NC R4 32 R3 28 NC R2 27 31 R1 26 NC R0 25 30 G5 24 29 G4 23 G1 22 G0 19 G2 B4 18 G3 B3 17 21 B2 16 20 B1 15 11 14 RESET 10 CS RS 9 B0 GND 8 13 DE 7 12 SCL SDI 6 VSYNC LED- 2 5 LED+ 1 NO.
