Description

一种建筑用广告展示屏 技术领域
本发明涉及一种显示装置，特别涉及一种建筑用广告展示屏。
背景技术
近几年来透明液晶屏幕在播放广告方面具有越来越多的应用，但由于其需要在有稳定背光场的环境下进行使用，因此就给透明液晶屏幕的广泛应用造成了障碍，另其目前只能应用在展箱、展柜、冰箱或榨汁机等拥有后背密闭空间的设备中，不能独立的作为显示装置进行应用。目前现有技术有将透明液晶屏幕与雾化玻璃进行组合，实现单独显示的功能，但也多应用于展箱、展柜或冰箱中，起到了节约电能，防止温度过高等作用，但是将其应用于门窗、幕墙、隔断或户外广告展示牌等领域还未有报道。
技术解决方案
为了解决上述技术问题，本发明提供一种建筑用广告展示屏，可以作为门窗、幕墙、隔断或户外广告展示牌等进行应用，技术方案为：
一种建筑用广告展示屏，包括框架、固定于框架上的透明液晶显示屏层和雾化玻璃层、与透明液晶显示屏层和雾化玻璃层相连的控制单元，框架、透明液晶显示屏层和雾化玻璃层共同形成一个密闭的中空结构，中空结构内设置有发光设备。
优选地，发光设备位于框架的内侧面。
本发明提供的建筑用广告展示屏，将电子雾化玻璃、发光设备和透明液晶显示屏进行有机结合，利用上述三种设备相关参数的配合设置，来保证观察者既可以清晰的看清透明液晶显示屏上播放的内容，又可以使得屏幕在不显示内容时变得通透，解决透明液晶屏幕既能显示，又能通透的问题。
一种建筑用广告展示屏，包括框架、固定于框架上的透明液晶显示屏层和雾化玻璃层、与透明液晶显示屏层和雾化玻璃层相连的控制单元，框架、透明液晶显示屏层和雾化玻璃层共同形成一个密闭的中空结构，框架的内侧面上设置有发光设备，透明液晶显示屏层与雾化玻璃层之间的距离X为2-5cm，发光设备的光通量与透明显示屏面积之间的关系为300-500lm/m2。
本发明提供的建筑用广告展示屏，抗压强度高，稳定性好，液晶显示屏层和雾化玻璃层的使用寿命长；在广告显示状态时，显示内容清晰度高，在户外四周均具有自然光的状态下也可以清晰的看见透明液晶显示屏层上显示的广告内容；在不显示广告的状态下，整个广告展示屏的通透性好，可以清晰的看见广告显示装置后方的物品。
进一步地，框架为矩形框架，矩形框架的长与宽的比例大于1.75时，发光设备对称设置在在矩形框架的长边所对应的内侧面上，保证显示内容清晰度的同时，降低施工复杂程度，节约人工成本。
优选地，透明显示屏层的对角线长度为M，当M不大于76.2cm时，距离X为2cm；当M大于76.2cm时，X与M之间的关系如下： X=0.1M/3.5+0.01(M-90)。距离X一方面实现为了满足光通量要求而对发光设备的容纳，同时对稳定性和显示内容的清晰度、通透状态时候的广告展示屏的通透性都具有很大影响，满足上述关系的距离X设计，可以保证广告展示屏的通透性和显示内容清晰度同时达到较佳水平。
优选地，发光设备的光通量与透明显示屏面积之间的关系W为430lm/m2，满足显示内容清晰度的最佳单位面积光通量。
优选地，雾化玻璃层的长和宽均不小于透明液晶显示屏层的长和宽，发光设备为LED灯带。
更进一步地，透明液晶显示屏层包括两层保护玻璃和夹在保护玻璃中间的透明LCD显示屏；雾化玻璃层包括两层保护玻璃和夹在保护玻璃中间的调光膜；优选地，保护玻璃的厚度为2-5mm，进一步提高了广告展示屏的抗压强度和环境耐受能力。
更进一步地，中空结构内设置有与框架相接触的灯带支撑架，LED灯带设置于灯带支撑架的与透明液晶显示屏层相垂直的侧面上，利于安装，加固支撑，提高稳定性，同时提高装置寿命。
更进一步地，框架外侧还设置有密封胶层，框架与透明液晶显示屏层与雾化玻璃层相接触的侧面，框架外侧的缝隙处均可以设置密封胶层，另整个广告展示屏防水防风防尘，提高寿命。
本发明提供了一种可以应用于建筑领域的，在户外或户内独立使用的广告展示屏，考虑建筑领域使用要求和具有自然光线的环境，合理设置透明显示屏层和雾化玻璃层之间的距离X和发光设备光通量与透明显示屏层之间的关系W，使广告显示装置稳定性好，两个因素相互协同，中和外界光线的影响，另广告展示屏在显示状态时显示的内容清晰度高，非显示状态时整个屏幕的通透性好，具有较大的室内外独立应用前景。

随机选取22位志愿者，年龄在17-45岁之间，对实施例2-15和对照实施例1-10所提供的建筑用广告展示屏在展示状态和通透状态的显示效果进行考察，在雾化玻璃雾化，发光设备发光，透明液晶显示屏进行广告显示时，对显示内容的清晰程度进行评分；在透明液晶显示屏空白状态和雾化玻璃透明状态时，观察广告显示装置后物品的清晰程度，对整个广告显示装置的通透性进行评分；对应的评分标准见表3。并将每个广告展示屏的得分去掉最高分和最低分，然后计算平均得分，结果见表4。

由上述试验结果可知，本发明实施例2-15所提供的建筑用广告展示屏与对照例1-9相比，兼具良好的显示状态清晰度和非显示状态通透性，距离X为20-50mm，每平米透明显示屏需求的光通量在300-500lm时，得到的广告展示屏，可以平衡显示内容的清晰度和整体不显示状态的通透性，适应于建筑应用。
其中实施例2-6的广告展示屏通透性较好，均在4.9以上，清晰度也在4.65之上，其中实施例3的清晰度得分高达4.95；实施例7和8与实施例4相对比，改变距离X，导致清晰度和通透性均有一定程度下降；实施例9和10与实施例6相对比，改变距离X，导致清晰度和通透性均有一定程度下降；当距离X与M按照一定关系进行设置时，可以平衡清晰度和通透性；实施例11-13与实施例5相对比，改变W值，可知当W为430 lm/m2时，显示内容的清晰度最佳；对照例1和对照例2与实施例2相对比，在单位面积光通量相同的情况下，距离X为1和6时，清晰度和通透性均明显降低，对照例3-6与实施例5相比较，在其他条件相同的情况下，改变单位面积光通量，对显示效果的影响较大，在光通量超过500后，对清晰度的提高没有帮助，同时会过量的灯光会产生光污染和能量的浪费；对照例7-9与实施例6相比较可知，在其他条件相同的情况下，改变距离X，结果可知过大和过小的距离对清晰度和通透性均有不利的影响。
以上实施例仅为对本发明的优选实施方式进行描述，并非对本发明的范围进行限定，在不脱离本发明设计精神的前提下，本领域普通技术人员对本发明的技术方案作出的各种变形和改进，均应落入本发明的权利要求书确定的保护范围内。
