作者:admin  10bet体育官方网站:2017-04-26 10:06:22
权衡特征和技能条件的优缺点是显现器挑选过程中的第一步,并且,用于工业设备中显现器的运用与一般面向消费类的商品不同。在挑选时应该考虑以下七点根本要素。
Weighing the advantages and disadvantages of features and skills is the first step in the selection process of the device, and the use of industrial devices in the display and the general consumer oriented products. The following seven elements should be considered when selecting.
一、整机稳定性(包含运用时间、抗搅扰等)
First, the stability of the whole machine (including the use of time, anti interference, etc.)
显现器在构成闭路监控体系时,一般需求天天24小时,每年365天接连无间断的通电运用(而电视机一般天天仅作业几小时),并且某些显现器的运用环境也许较为恶劣,这就请求显现器的可靠性和稳定性更高。与电视机比较而言,在规划上,显现器的电流、功耗、温度及抗电搅扰、电冲击的才能和裕度以及均匀无故障运用时间均要远大于电视机,一起显现器还必须运用全屏蔽金属外壳保证电磁兼容和搅扰功用;在元器件的选型上,显现器运用的元器件的耐压、电流、温度、湿度等各方面特性都要高于电视机运用的元器件;而在安装、调试尤其是元器件和整机老化的工艺请求上,显现器的请求也更高,电视机制作时整机老化一般是在流水线上常温通电8小时左右,而显现器的整机老化则需求在高温、高湿密闭环境的老化流水线上通电老化24小时以上,以保证整机的稳定性。
Display in the form of closed-circuit monitoring system, the general needs 24 hours a day, 365 days a year for uninterrupted electricity use (and generally only a few hours every day TV work), and some display application environment maybe is bad, this request displays the reliability and stability of higher. Compared with TV, in the planning, display the current, power, temperature and electric, electric shock and disturb to margin and uniform fault free use time are far greater than the TV display, together we must use a fully shielded metal shell to ensure electromagnetic compatibility and interference function; in the selection of components. Show the characteristics of various aspects of device use components of voltage, current, temperature and humidity are higher than the TV application components; and in the installation and debugging of particular request process components and the aging on the display request is higher, the TV production is generally in line at room temperature aging power 8 an hour or so, and display the overall demand of electricity in aging aging pipeline with high temperature and humidity in closed environment on aging for more than 24 hours, to ensure the stability of the machine Of.
二、图画清晰度
Two, picture clarity
液晶显现器具有直观反映图画质量的功用,加之全1920*1080分辨率关于广播电视领域的显现设备的选用,液晶显现器是优先挑选的显现器,专业显现器分辨率是依据显现输出主动调整分辨率(不管反正都能够支撑);其高可靠性和高清晰显现才能将保证您能够将记载编辑好的高清晰影音,视频信号完好的显现在观看者眼前。
LCD display with intuitive picture quality reflect the function and selection of equipment show full 1920*1080 resolution on the field of radio and television, LCD display is the preferred choice, professional display resolution is based on the output of the initiative to adjust the resolution show (no matter anyway to support); its high reliability and ability will ensure clear you will be able to edit the recorded high-definition video, appeared in front of watching video signal integrity.
.
反之,液晶电视只支撑阐明书中规定的几种电视常用分辨率。因为民用电视信号的分辨率只需几种,电视LCD只需依据民用用户运用的常用几个分辨率进行作用处理,特殊分辨率会致使花屏。
On the contrary, LCD TV only supports the introduction of several commonly used in the resolution of the resolution of the book. Because the resolution of the civilian television signal needs only a few, the television LCD only need to be used in accordance with the common use of several resolutions of the user, the special resolution will cause the screen.
三、颜色复原度
Three, color restoration
如果说清晰度主要是由视频通道的幅频特性决议的话,复原度则主要由显现器中有红(R)、绿(G)、蓝(B)三基色的色度信号和亮度信号的相位所决议。因为显现器所调查的一般为静态图画,因此对显现器颜色复原度的请求比电视机更高,故专业显现器的视放通道在亮度、色度处理和R、G、B处理上应具有准确的抵偿电路和推迟电路,以保证亮/色信号和R、G、B信号的相位同步。
If clarity is mainly determined by the amplitude and frequency characteristics of the video channel, the recovery is mainly determined by the display of the red (R), green (G), blue (B) three primary color signal and the brightness of the signal phase. Because the display in general static pictures, so the higher the display color restoration degree requirements than television, the video channel in the professional appearance of brightness and color processing, G, B and R should be treated with compensation circuit and delay circuit is accurate, to ensure that the light / color signal and phase R, G, B signal synchronization.
反之,液晶电视因为运用环境请求所至,图象是经过润饰处理后进行显现。不能完全实在反映实际作用。
On the other hand, because the use of LCD TV to the environment request, the image is polished processing after show. Can not fully reflect the actual role.
四、机器资料的运用
Four, the use of machine data
因为运用环境的请求,液晶电视机器外壳原料有些选用金属质地。且内部板线都是工业化规划,不简单老化;节能环保理念的体现:低能耗规划;环保资料运用。规整的外观,便于拼接,组合安装等工业需求。
Because of the use of the environment, some of the LCD TV machine shell metal material selection. And the internal board line is the industrialization plan, not simple aging; energy saving and environmental protection concept embodied: low energy consumption planning; environmental protection materials. Regular appearance, easy to splice, assembly and other industrial needs.
反之,液晶电视整机外壳悉数为非金属原料规划。内部板线是选用民用规划,长时间开机简单形成机件老化。另外民用电视外观多对错规矩外观,附带音响体系、外观圆弧体系等作为听觉和视觉的隶属设备,施工起来全体美观和作用都会大打折扣。
On the contrary, the LCD TV casing for non-metallic raw materials planning. Internal board line is the use of civilian planning, a long time to boot the formation of mechanical aging. In addition, the appearance of civil TV more than the wrong appearance, coupled with the sound system, the appearance of the arc system as a hearing and visual subordinate equipment, the construction of all the beautiful and the role will be greatly reduced.
五、端口
Five, port
液晶显现器多选用工业端口例如RGBBNC的色差带自锁机构的接口和专业的DVI-D视频接口;反之,液晶电视则没有BNC自锁色差输入接口和DVI-D接口。
Liquid crystal display device to choose the industrial port, such as RGBBNC with the interface of the self locking mechanism and professional DVI-D video interface; on the contrary, there is no LCD TV BNC self-locking color input interface and DVI-D interface.
六、操控接口
Six, control interface
液晶显现器可选用S232串口操控,敞开的操控口令多达200多条,适应各种工业环境。便利多显现器运用时,不必经过遥控器就能够操控一切显现设备,并能够辅佐,守时开机,延时开机、机器自检等各种工业请求。
LCD display can choose S232 serial control, open up to more than and 200 passwords, to adapt to a variety of industrial environment. When the utility model is convenient to use, the utility model can be used to control all the display devices without being controlled by the remote controller, and can be used for various industrial requirements, such as the auxiliary, the punctual boot, the delayed start, the machine self inspection, etc..
反之,液晶电视也可选用S232串口操控。但只能完成遥控器所具有的操控指令。并不能完成工业操控。
On the contrary, LCD TV can also choose S232 serial control. But can only complete the remote control command. Can not complete industrial control.
七、无风扇架构
Seven, no fan architecture
液晶显现器在规划上选用无机械排风扇来坚持空气流通和散热,从而防止因为机械排风扇致使的尘埃和风扇噪音疑问,当内部温度因为不明原因此增加时,显现器主动操控背光体系将温度坚持在最高作业温度之下。
LCD in the planning with no mechanical exhaust fan to keep air circulation and cooling, thereby preventing dust because of mechanical exhaust fan and fan noise in doubt, when the internal temperature for unknown reasons this increase, the display backlight system will adhere to the active manipulation of temperature under the highest working temperature.
反之,液晶电视因为运用的环境所致,对此无严格请求。
On the contrary, LCD TV because of the use of the environment, there is no strict request.
