Contrast Ratio(CR) is defined mathematically as : Surface Luminance with all white pixels Contrast Ratio = ---------------------------------------------------------Surface Luminance with all black pixels 2. Surface luminance is the center point across the LCD surface 500mm from the surface with all pixels displaying white. For more information see FIG 1. 3. Response time is the time required for the display to transition from white to black (Rising Time, Tr) and from black to white (Falling Time, Tf). For additional information see FIG 2. 4. Viewing angle is the angle at which the contrast ratio is greater than 10. The angles are determined for the horizontal or x axis and the vertical or y axis with respect to the z axis which is normal to the LCD surface. For more information see FIG 3. FIG. 1 Optical Characteristic Measurement Equipment and Method www.rocktech.com.hk RK055AHD091-CTG FIG. 2 The definition of Response Time The response time is defined as the following figure and shall be measured by switching the input signal for “black” and “white”. Response Time = Rising Time(Tr) + Falling Time(Tf) - Rising Time(Tr) : Full White 90%  Full White 10% Transmittance. - Falling Time(Tf) : Full White 10%  Full White 90% Transmittance. FIG. 3 The definition of Viewing Angle Use Fig. 1(Test Procedure) under Measurement System to measure the contrast from the measuring direction specified by the conditions as the following figure. www.rocktech.com.hk RK055AHD091-CTG 5.Block Diagram 720*3(RGB)*1280 Display Panel (TFT LCD Transmissive) Gate signal (1280 ) Source signal (720*3) Driver & Controller (All-In-One) (RM68200) C P U Data(D0N,D0P,D1N,D1P,D2N,D2P,D 3N,D3P),Power( VCC & IOVCC) & & P O W E R Control Signal(CLKP,CLKN RESET) www.rocktech.com.hk RK055AHD091-CTG 6.Pin Description Item Symbol Description 1 LEDK Backlight Cathode input pin. 2 LEDA Backlight Anode input pin. 3 NC NC 4 GND GND 5 MIPI_TDN0 MIPI DSI data-0 signal line (-). 6 MIPI_TDP0 MIPI DSI data-0 signal line (+). 7 GND GND 8 MIPI_TDN1 MIPI DSI data-1 signal line (-). 9 MIPI_TDP1 MIPI DSI data-1 signal line (+). 10 GND GND 11 MIPI_TCN MIPI DSI Clock strobe signal line (-). 12 MIPI_TCP MIPI DSI Clock strobe signal line (+). 13 GND GND 14 MIPI_TDN2 MIPI DSI data-2 signal line (-) 15 MIPI_TDP2 MIPI DSI data-2 signal line (+) 16 GND GND 17 MIPI_TDN3 MIPI DSI data-3 signal line (-) 18 MIPI_TDP3 MIPI DSI data-3 signal line (+) 19 GND GND 20 GND GND 21 LRSTB LRSTB 22 LPTE Tearing effect output pin to synchronies MCU to frame writing, activated by S/W command. 23 VDD 2.8 Power supply VDD 24 LCD_ID NC 25 IOVCC 1.8 Power supply VDD 26 CTP_SDA CTP I2C Data 27 CTP_SCL CTP I2C Clock 28 CTP_RST CTP Reset 29 CTP_INT CTP Interrupt 30 VDD 3.3 CTP Working voltage 2.8-3.3V 31 GND GND CTP IC driver source code will be offered separately. www.rocktech.com.hk RK055AHD091-CTG 7.Timing Characteristics(Details refer to RM68200 spec) www.rocktech.com.hk RK055AHD091-CTG www.rocktech.com.hk RK055AHD091-CTG www.rocktech.com.hk RK055AHD091-CTG 8.Outline Dimension www.rocktech.com.hk RK055AHD091-CTG 9.

As glass is fragile, it tends to become or chipped during handling especially on the edges. Please avoid dropping or jarring. Do not subject it to a mechanical shock by dropping it or impact. (2) If the display panel is damaged and the liquid crystal substance leaks out, be sure not to get any in your mouth. If the substance contacts your skin or clothes, wash it off using soap and water. (3) Do not apply excessive force to the display surface or the adjoining areas since this may cause the color tone to vary. Do not touch the display with bare hands. This will stain the display area and degraded insulation between terminals (some cosmetics are determined to the polarizer). (4) The polarizer covering the display surface of the LCD module is soft and easily scratched. Handle this polarizer carefully. Do not touch, push or rub the exposed polarizers with anything harder than an HB pencil lead (glass, tweezers, etc.). Do not put or attach anything on the display area to avoid leaving marks on. Condensation on the surface and contact with terminals due to cold will damage, stain or dirty the polarizer. After products are tested at low temperature they must be warmed up in a container before coming is contacting with room temperature air. (5) If the display surface becomes contaminated, breathe on the surface and gently wipe it with a soft dry cloth. If it is heavily contaminated, moisten cloth with one of the following solvents - Isopropyl alcohol - Ethyl alcohol Do not scrub hard to avoid damaging the display surface. (6) Solvents other than those above-mentioned may damage the polarizer. Especially, do not use the following. - Water - Ketone - Aromatic solvents Wipe off saliva or water drops immediately, contact with water over a long period of time may cause deformation or color fading. Avoid contacting oil and fats. (7) Exercise care to minimize corrosion of the electrode. Corrosion of the electrodes is accelerated by water droplets, moisture condensation or a current flow in a highhumidity environment. (8) Install the LCD Module by using the mounting holes. When mounting the LCD module make sure it is free of twisting, warping and distortion. In particular, do not forcibly pull or bend the I/O cable or the backlight cable. (9) Do not attempt to disassemble or process the LCD module. (10) NC terminal should be open. Do not connect anything. (11) If the logic circuit power is off, do not apply the input signals. (12) Since LCM has been assembled and adjusted with a high degree of precision, avoid applying excessive shocks to the module or making any alterations or modifications to it. - Do not alter, modify or change the shape of the tab on the metal frame. - Do not make extra holes on the printed circuit board, modify its shape or change the positions of components to be attached. - Do not damage or modify the pattern writing on the printed circuit board. - Absolutely do not modify the zebra rubber strip (conductive rubber) or heat seal www.rocktech.com.hk RK055AHD091-CTG connector. - Except for soldering the interface, do not make any alterations or modifications with a soldering iron. - Do not drop, bend or twist LCM. Storage Precautions When storing the LCD modules, the following precaution is necessary. (1) Store them in a sealed polyethylene bag. If properly sealed, there is no need for the dessicant. (2) Store them in a dark place. Do not expose to sunlight or fluorescent light, keep the temperature between 0°C and 35°C. (3) The polarizer surface should not come in contact with any other objects. (We advise you to store them in the container in which they were shipped). Others Liquid crystals solidify under low temperature (below the storage temperature range) leading to defective orientation or the generation of air bubbles (black or white). Air bubbles may also be generated if the module is subject to a low temperature. If the LCD modules have 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 contrast 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 by static electricity etc., exercise care to avoid holding the following sections when handling the modules. - Exposed area of the printed circuit board. -Terminal electrode sections. www.rocktech.com.hk
