See the diagram below for configuration methods and timings: ## **Timing for initial setting slave address to 0xBA/0xBB:** ## **Timing for initial setting slave address to 0x28/0x29:** Page 8 of 23 ## **3.3 I2C Timing** ## **3.3V communication interface, 400Kbps, pull up resistor is 2K ohm** ## **3.4 Data Transmission** - (ex: slave address is 0xBA/0xBB) Communication is always initiated by master, A high-to-low transition of SDA with SCL high is a All addressing signal are serially transmitted to and from on bus in 8-bit word. GT911 sends a “0” to acknowledge when the addressing word is 0xBA/BB (or 0x28/0x29 ). This happens during the ninth clock cycle. If the slave address is not matched, GT911 will stay in idle state. The data words are serially transmitted to and from in 9-bit formation: 8-bit data + 1-bit ACK or NACK sent by GT911. Data changes during SCL low periods & keeps valid during SCL high. A low-to-high transition of SDA with SCL high is a stop condition. Page 9 of 23 ## **3.5 Write Data to GT911** (ex: slave address is 0xBA/0xBB) ## **Write operations** Please check the above figure, master start the communication first, and then sends device address 0XBA preparing for a write operation. After receiving ACK from GT911, master sends out 16-bit register address, and then the data word in 8-bit, which is going to be wrote into GT911. The address pointer of GT911 will automatically increase one after one byte writing, so master can sequentially write in one operation. When operation finished, master stop the communication. ## **3.6 Read Data from GT911** (ex: slave address is 0xBA/0xBB) ## **Read operations** The diagram above is the timing sequence of the host reading data from GT911. First, the host issues a Start condition and sends 0XBA (address bits and R/W bit; R/W bit as 0 indicates Write operation) to the slave device. After receiving ACK, the host sends the 16-bit register address (where reading starts) to the slave device. Then the host sets register addresses which need to be read. Also after receiving ACK, the host issues the Start condition once again and sends 0XBB (Read Operation). After receiving ACK, the host starts to read data. GT911 also supports continuous Read Operation and, by default, reads data continuously. Whenever receiving a byte of data, the host sends an ACK signal indicating successful reception. After receiving the last byte of data, the host sends a NACK signal followed by a STOP condition which terminates communication. ## **3.7 Coordinates Information** Page 10 of 23 - Addr = [Register_H : Register_L] Buffer status, 1 = coordinate (or key) is ready for host to read; 0 = coordinate (or key) is not ready and data is not valid. After reading coordinates, host should configure this flag (or the entire byte) to 0 via I2C. Large detect, 1 indicates there is large-area touch on TP.

(In order to satisfy the supplying stability, management optimization and the best product performance...etc, under the premise of not affecting the electrical characteristics and external dimensions, Midas have the right to modify the version.) - (10) Midas has the right to upgrade or modify the product function. ## **1. Handling Precautions** - (1) Since the display panel is being made of glass, do not apply mechanical impacts such as dropping from a high position. - (2) If the display panel is broken by some accident and the internal organic substance leaks out, be careful not to inhale nor lick the organic substance. - (3) If pressure is applied to the display surface or its neighborhood of the OLED display module, the cell structure may be damaged. So, be careful not to apply pressure to these sections. - (4) The polarizer covering the surface of the OLED display module is soft and easily scratched. - (5) When the surface of the polarizer of the OLED display module has soil, clean the surface. It takes advantage by using following adhesion tape. - Scotch Mending Tape No. 810 or an equivalent - Never try to breathe upon the soiled surface nor wipe the surface using cloth containing solvent such as ethyl alcohol, since the surface of the polarizer will become cloudy. Also, pay attention that the following liquid and solvent may spoil the polarizer: - Water - Ketone - Aromatic Solvents - (6) Protection film is being applied to the surface of the display panel and removes the protection film before assembling it. At this time, if the OLED display module has been stored for a long period of time, residue adhesive material of the protection film may remain on the surface of the display panel after removed of the film. In such case, remove the residue material by the method introduced in the above Section 5. - (7) Do not touch the following sections whenever possible while handling the OLED display modules. - Pins and electrodes - Pattern layouts such as the TCP & FPC - (8) Hold OLED display module very carefully when placing OLED display module into the System housing. Do not apply excessive stress or pressure to OLED display module. And, do not over bend the film with electrode pattern layouts. These stresses will influence the Page 21 of 23 display performance. Also, secure sufficient rigidity for the outer cases. - (9) Do not apply stress to the LSI chips and the surrounding molded sections. - (10) Pay sufficient attention to the working environments when handing OLED display modules to prevent occurrence of element breakage accidents by static electricity. - Be sure to make human body grounding when handling OLED display modules. - Be sure to ground tools to use or assembly such as soldering irons. - To suppress generation of static electricity, avoid carrying out assembly work under dry environments. - Protective film is being applied to the surface of the display panel of the OLED display module. Be careful since static electricity may be generated when exfoliating the protective film. ## **2. Storage Precautions** - (1) When storing OLED display modules, put them in static electricity preventive bags to avoid be directly exposed to sun or lights of fluorescent lamps. (We recommend you to store these modules in the packaged state when they were shipped from Midas. At that time, be careful not to let water drops adhere to the packages or bags.) - (2) When the OLED display module is being dewed or when it is placed under high temperature or high humidity environments, the electrodes may be corroded if electric current is applied. Please store it in clean environment. ## **3. Designing Precautions** - (1) The absolute maximum ratings are the ratings which cannot be exceeded for OLED display module, and if these values are exceeded, OLED display module may be damaged. - (2) To prevent occurrence of malfunctioning by noise, pay attention to satisfy the VIL and VIH specification and to make the signal line cable as short as possible. - (3) We recommend you to install excess current preventive unit (fuses, etc.) to the power circuit (VDD / VCC). (Recommend value: 0.5A) - (4) Pay sufficient attention to avoid occurrence of mutual noise interference with the nearby devices. - (5) As for EMI, take necessary measures on the equipment side basically. - (6) If the power supplied to the OLED display module is forcibly shut down by such errors as taking out the main battery while the OLED display panel is in operation, we cannot guarantee the quality of this OLED display module. - Connection (contact) to any other potential than the above may lead to rupture of the IC. - (7) If this OLED driver is exposed to light, malfunctioning may occur and semiconductor elements may change their characteristics. - (8) The internal status may be changed, if excessive external noise enters into the module. Therefore, it is necessary to take appropriate measures to suppress noise generation or to protect module from influences of noise on the system design. Page 22 of 23 - (9) We recommend you to make periodical refreshment of the operation statuses (re-setting of the commands and re-transference of the display data) to cope with catastrophic noise. - (10) It's pretty common to use "Screen Saver" to extend the lifetime and Don't use the same image for long time in real application. When an OLED display module is operated for a long of time with fixed pattern, an afterimage or slight contrast deviation may occur. - (11) The limitation of FPC and Film bending. - (12) The module should be fixed balanced into the housing, or the module may be twisted. **==> picture [254 x 50] intentionally omitted <==** **----- Start of picture text -----**

- (13) Please heat up a little the tape sticking on the components when removing it; otherwise the components might be damaged. ## **4. Precautions when disposing of the OLED display modules** - (1) Request the qualified companies to handle industrial wastes when disposing of the OLED display modules. Or, when burning them, be sure to observe the environmental and hygienic laws and regulations.
