6 Precautions of using LCD Modules

Mounting

- Mounting must use holes arranged in four corners or four sides.

- The mounting structure so provide even force on to LCD module. Uneven force (ex. Twisted stress)

should not applied to the module. And the case on which a module is mounted should have sufficient

strength so that external force is not transmitted directly to the module.

- It is suggested to attach a transparent protective plate to the surface in order to protect the polarizer. It

should have sufficient strength in order to the resist external force.

- The housing should adopt radiation structure to satisfy the temperature specification.

- Acetic acid type and chlorine type materials for the cover case are not desirable because the former

generates corrosive gas of attacking the polarizer at high temperature and the latter causes circuit

break by electro-chemical reaction.

- Do not touch, push or rub the exposed polarizers with glass, tweezers or anything harder than HB

pencil lead. Never rub with dust clothes with chemical treatment. Do not touch the surface of polarizer

for bare hand or greasy cloth.(Some cosmetics deteriorate the polarizer.)

- When the surface becomes dusty, please wipe gently with absorbent cotton or other soft materials like

chamois soaks with petroleum benzine. Normal-hexane is recommended for cleaning the adhesives

used to attach front / rear polarizers. Do not use acetone, toluene and alcohol because they cause

chemical damage to the polarizer.

- Wipe off saliva or water drops as soon as possible. Their long time contact with polarizer

Operating

- The spike noise causes the mis-operation of circuits. It should be within the ± 200mV level (Over and

under shoot voltage)

- Response time depends on the temperature.(In lower temperature, it becomes longer.)

- Brightness depends on the temperature. (In lower temperature, it becomes lower.) And in lower

temperature, response time(required time that brightness is stable after turned on) becomes longer.

- Be careful for condensation at sudden temperature change. Condensation makes damage to polarizer

or electrical contacted parts. And after fading condensation, smear or spot will occur.

- When fixed patterns are displayed for a long time, remnant image is likely to occur.

- Module has high frequency circuits. Sufficient suppression to the electromagnetic interference shall be

done by system manufacturers. Grounding and shielding methods may be important to minimized the

interference

Electrostatic Discharge Control

Since a module is composed of electronic circuits, it is not strong to electrostatic discharge. Make certain

that treatment persons are connected to ground through wrist band etc. And don’t touch interface pin

directly.

Strong Light Exposure

Strong light exposure causes degradation of polarizer and color filter.

Storage

When storing modules as spares for a long time, the following precautions are necessary.

- Store them in a dark place. Do not expose the module to sunlight or fluorescent light. Keep the

temperature between 5 ° C and 35 ° C at normal humidity.

- The polarizer surface should not come in contact with any other object. It is recommended that they

be stored in the container in which they were shipped.

Protection Film

- When the protection film is peeled off, static electricity is generated between the film and polarizer.

This should be peeled off slowly and carefully by people who are electrically grounded and with well

ion-blown equipment or in such a condition, etc.

- The protection film is attached to the polarizer with a small amount of glue. If some stress is applied to

rub the protection film against the polarizer during the time you peel off the film, the glue is apt tore

main on the polarizer. Please carefully peel off the protection film without rubbing it against the

polarizer.

- When the module with protection film attached is stored for a long time, sometimes there remains a

very small amount of glue still on the polarizer after the protection film is peeled off.

- You can remove the glue easily. When the glue remains on the polarizer surface or its vestige is

recognized, please wipe them off with absorbent cotton waste or other soft material like chamois

soaked with normal-hexane.

Transportation

The LCD modules should be no falling and violent shocking during transportation, and also should avoid

excessive press, water, damp and sunshine.

建议每边安装间隙 (A) 约为 0.3 ~0.5mm.

建议面板厚度 (B) 约为 1.5~4.0mm.

2. A silicon sealing ring ships with TOPWAY display module. It

should be in place before assembling to the front panel.

TOPWAY 显示模块上的硅胶密封圈在安装时确保嵌入到位 .

3. It should fix the TOPWAY display module into the front panel

with two steps.

 Pre-fixing: Slightly tighten the screws on beam clamp in

sequence as picture on the right side.

 Final-fixing: Tighten the fixing screws on beam clamp in

sequence as well with twist torque about 6~8kg.cm (*1) .

and put the beam clamp straight.

Note:

*1. Over tightening might damage the shell and cause bad sealing result.

应分两步将 TOPWAY 显示模块固定在面板上 .

预紧 : 将卡扣螺钉按右图所示顺序稍加预紧 .

紧定 : 再次按顺序用 6~8kg.cm 扭力拧紧卡扣螺钉 (*1), 并注

意卡扣置正无歪斜 .

注 :

*1. 过度拧紧可能会损坏外壳和影响密封效果 .

4. It is strongly suggested to check the seal balancing of the

four-side of the TOPWAY display module.

 The suggested after assemble sealed gap(C) should be

about 1.0~1.5mm.

需注意检查 TOPWAY 显示模块四周在安装后保证平衡密封 .

建议组装后的密封间隙 (C) 约为 1.0 ~1.5 mm.

5. Others:

 Never hot plug the device! Power off the device before connect or disconnect the display

module.

 Don't forget to remove the cover protective film for normal operation.

其它 :

视频线禁止带电插拔！在连接或断开显示模块之前先关闭设备电源 .

使用前请揭去保护膜 .

SMART LCD Command Manual

Protocol V6.12

1 Basic Specifications

TOPWAY Smart LCD serial command is for real-time control and access. Host machine get the data

which input through the Smart LCD interface or provide the data for display.

1.1 Hardware connection

Smart LCD serial UART interface are mainly base on RS232-C standard, by default, config as 8N1

115200bps.

2 Command Structure

2.2 Packet Timeout

TOPWAY SmartLCD support Timeout setting, which can be defined in editor project setting.

Timeout options: None, 1s, 2s, 3s, 5s, 10s, 20s. If timeout, The incomplete Packet will be discarded.

2.3 Packet Acknowledgment

Packet Acknowledgment is two byte in ASCII (module  host):

Response

code Description

Command (in packet) executed and

":>" In ASCII

wait for next Command

(0x3a, 0x3e)

Command (in packet) error and
