Handling Precautions1) Since front polarizer is easily damaged, pay attention not to scratch it.2) Be sure to turn off power supply when inserting or disconnecting from input connector. 3) Wipe off water drop immediately. Long contact with water may cause discoloration or spots.4) When the panel surface is soiled, wipe it with absorbent cotton or other soft cloth.5) Since the panel is made of glass, it may break or crack if dropped or bumped on hard surface.6) Since CMOS LSI is used in this module, take care of static electricity and insure human earth when handling.7) Do not open nor modify the Module Assembly.8) Do not press the reflector sheet at the back of the module to any directions.9) At the insertion or removal of the Signal Interface Connector, be sure not to rotate nor tilt the Interface Connector of the TFT Module.11) After installation of the TFT Module into an enclosure (Notebook PC Bezel, for example), do not twist nor bend the TFT Module even momentary. At designing the enclosure, it should be taken into consideration that no bending/twisting forces are applied to the TFT Module from outside. Otherwise the TFT Module may be damaged. 12) S mall amount of materials having no flammability grade is used in the LCD module. The LCD module should be supplied by power complied with requirements of Limited Power Source (IEC60950 or UL1950), or be applied exemption. 13) D isconnecting power supply before handling LCD modules, it can prevent electric shock, DO NOT TOUCH the electrode parts, cables, connectors and LED circuit part of TFT module that a LED light bar build in as a light source of back light unit. It can prevent electrostatic breakdown.5 of 31B101EW03 V0 document version : 0.12.

Definition of viewing angleViewing angle is the measurement of contrast ratio ≧10, at the screen center, over a 180° horizontal and180° vertical range (off-normal viewing angles). The 180° viewing angle range is broken down as follows; 90° (θ) horizontal left and right and 90° (Φ) vertical, high (up) and low (down). The measurement direction is typically perpendicular to the display surface with the screen rotated about its center to develop the desired measurement viewing angle.11 of 31B101EW03 V0 document version : 0.1 3.

4014蓝光 光通量
4014蓝光光通量
4014是一款常见的灯珠芯片,它以3、5为主,亮度强劲。
但不同灯头或不同驱动电路情况下,4014芯片的实际光通量也会有差异。
一般来说,4014 3芯片的光通量大约在150~200流明之间。
5芯片则在250~350流明之间。
这些数据仅供参考,具体会受以下因素影响:
1. 驱动电流大小:驱动电流越大,光通量越强。
一般3芯片采用350-500左右,5芯片600-1000。
2. 铝盖设计:采用不锈钢镀铬盖或镀铝盖,可以提高散热效果,有利于发挥更高光通量。
3. 散热结构:如采用高效散热芯或多片式散热叶片,有助于降低温度,延长使用寿命。
4. 光学系统设计:优化光学结构可以提高光利用率,同时降低光斑,光通量自然就更高。
5. 测试条件:一般光通量数据采用正常温度25°下进行测试。
实际使用环境较热时,光通量会下降一些。
要了解一个4014灯头的真实光通量,不如亲自测试,不能完全依赖于参数指标。
选购4014产品时最好看一看实物效果。

4合一光罩 半导体
光罩（也称为光掩模）是用于制造集成电路的重要工具，它决定了集成电路的图案和形状。
光罩由石英玻璃制成，具有极高的透明度，并且在制造过程中需要进行精细的加工和清洗。
在制造集成电路的过程中，光罩被放置在硅片上，通过曝光和显影等过程，将光罩上的图案转移到硅片上。
而4合1光罩是一种将4个芯片或器件的图案集成到一个光罩上的技术。
这种技术的应用可以减少光罩的数量，从而降低制造成本和生产时间。
同时，由于减少了光罩的数量，也减少了制造过程中的误差和缺陷的可能性。
在半导体领域中，4合1光罩技术的应用越来越广泛。
例如，在制造液晶显示器、LED灯、太阳能电池等产品时，常常需要用到这种技术。
通过将多个芯片或器件的图案集成到一个光罩上，可以大大提高生产效率和降低成本。
总的来说，4合1光罩技术是一种重要的半导体制造技术，它可以提高生产效率、降低成本，并且有助于推动半导体产业的发展。
405nm四分之一波片
405nm四分之一波片
405nm四分之一波片是一种光学元件，通常由蓝光滤光片制成。
它可以选择性地传递或阻挡405nm波长的光线，而将其他波
长的光线完全或部分反射掉。
四分之一波片的设计原理基于光的偏振状态，它可以将入射光线分解为垂直方向和平行方向的两个分量，实现对光的控制与调节。
四分之一波片被广泛应用于激光器、光学仪器、显微镜和光学通信等领域。
在激光器中，它可以将线性偏振光转换为圆偏振光或逆时针偏振光，用于特定的实验或应用。
在显微镜中，四分之一波片可以用于分辨光学图像中的细节，提高成像的质量。
在光学通信中，它可以用于光信号的调制和解调，提高信号的传输效率和稳定性。
总之，405nm四分之一波片是一种重要的光学元件，它可以实现对光的偏振状态的调节和控制，广泛应用于光学领域中的各种应用中。

超薄面板灯光学报告1.超薄面板灯外观图
2.超薄面板灯结构尺寸图
3.超薄面板灯裸光源总光通量计算
以我司供应商4014灯珠为例，如下图（4014灯珠规格书截图）：
由此可见，4014单颗灯珠色温3000K和4000K的光通量供应商建议取值为20LM和21LM。
那么，一颗灯珠，暖白色温3000K为20LM每颗灯，若36W面板灯使用192PCS灯珠，那么暖白色温，36W面板灯的光通量即为20lm*192=3840LM；自然白4000K为21LM每颗灯，若36W面板灯使用192PCS灯珠，那么暖自然白色温，36W面板灯的光通量即为21lm*192=4032LM.
4.依照灯具结构影响光效还有如下因素：
A．导光板理想透光率为90%，此处会损失10%的光通量；
B．扩散板，PS材质理想透光率85%，此处会损失15%的光通量；
C.反射膜光反射率96%，此处会损失4%的光通量；
由此理论上总光通量Φ=4032x0.9x0.85x0.96=2961.1LM
我司光色电综合测试仪测试所得总光通量如下：
由此可见理论值与实测值还有一些偏差，这是因为LED灯珠点亮后，温度会升高，光通量便有所下降，如果用积分球测试，会相对较高，这是因为积分球测试温度很短，只有几分钟，灯具温度还没有稳定下来，散热器表面温度还没有达到稳定状态。
灯珠光通量与温度的关系可以从下图说明（灯珠厂商4014灯珠规格书截图）：
因为温度所损耗的光通量Φ=1-2820/2961=4.8%，这个数值合乎目前LED灯珠散热水平。
