Description

防雾显示屏 技术领域
本发明涉及显示屏技术领域，特别涉及一种防雾显示屏。
背景技术
目前在交互智能平板行业，对画面显示质量有很高的要求。无论是采用红外触控技术的显示屏，还是采用电容触控技术的显示屏，其显示模组上一般都设有一层起保护作用的保护板。通常这层保护板与显示模组之间留有间隙，此间隙是为了避免保护板和显示模组相互影响，引起如彩晕、变形挤压等问题。而间隙处难免存在一定湿度的空气，当显示屏工作一段时间后，由于设备发热及外部冷空气的影响，保护板的内部表面会出现结露现象。保护板上的水雾会遮挡显示模组的图像，致使显示信息不完整，严重影响产品的使用。
发明内容
基于此，本发明在于克服现有技术的缺陷，提供一种防雾显示屏，结构简单，能够有效地解决保护板的结露问题。
其技术方案如下：

图2为本发明实施例所述的防雾显示屏的正视示意图。
附图标记说明：
1、显示模组，2、保护板，3、干燥器，4、充气装置，5、边框，6、底座，10、内腔，50、进气孔，51、排气孔。
具体实施方式
下面对本发明的实施例进行详细说明：
如图1-2所示，本实施例所述的防雾显示屏，包括显示模组1、保护板2、干燥器3及充气装置4，所述显示模块上设有边框5，所述保护板2设置于边框5上，该显示模组1、边框5以及保护板2之间形成内腔10，所述边框5上设有与内腔10连通的进气孔50，所述边框5上设有与内腔10连通的排气孔51，所述充气装置4与干燥器3相连，所述干燥器3与进气孔50连通。上述防雾显示屏，充气装置4抽入外部空气，外部空气经过干燥器3后形成干燥空气，干燥空气通过进气孔50进入内腔10并从排气孔51排出，内腔10中具有持续流动的干燥空气，使得内腔10的露点有效降低，避免保护板2的内部表面出现结露现象。该防雾显示屏结构简单，能够彻底解决保护板2上水雾遮挡显示模组1图像的问题，保证产品的使用性能。
需要说明的是，所述进气孔50也可以设置在保护板2或者显示模组1上，所述排气孔51也可以设置在保护板2或者显示模组1上，但是基于加工的方便性及外形的美观性，所述的进气孔50优选设置在边框5上，所述的排气孔51优选设置在边框5上。
如图2所示，所述边框5包括竖向设置的左框架和右框架及横向设置的上框架和下框架，所述上框架、左框架、下框架、右框架依次相连形成环状，所述进气孔50设置在下框架上，所述排气孔51设置在上框架上。干燥空气从下部进入内腔10，受热后从上部排出，保证其持续稳定地流动。优选地，所述进气孔50为多个，多个所述进气孔50间隔设置在下框架上，所述排气孔51为多个，多个所述排气孔51间隔设置在上框架上，所述干燥器3通过多个气管与多个进气孔50分别连通。干燥空气从多个进气孔50进入内腔10，使得整个内腔10的露点保持在一个较低的温度，彻底解决水雾问题。
在本实施例中，所述防雾显示屏还包括底座6，所述干燥器3与充气装置4分别固定在底座6上，实现干燥器3与充气装置4的固定。优选地，所述底座6固定在显示模组1上，与显示模组1形成一个整体，方便使用和运输。
本实施例所述的防雾显示屏还包括控制器，所述显示模块、充气装置4分别与控制器电性连接。当显示模块运行时，控制器会控制充气装置4运行， 将干燥空气持续地送入内腔10中。
其中，本实施例所述的保护板2为钢化玻璃，具有良好的机械性能和耐热抗震性能。所述干燥器3为CMD膜干燥器，CMD膜干燥器由成千上万根中空纤维膜丝组成，对水分具有极强的渗透作用，利用反吹空气进行干燥，露点控制更低，干燥效果更好，且无需维护，可长期使用。所述充气装置4为微型充气泵，占用空间小，质量小。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
