下面参考附图和可选的实施例对本申请作进一步说明。
参考图1至图4所示，本申请实施例公布了一种显示面板的刻度尺100，刻度尺100包括：刻度板120，标有刻度121和计数型标记122；发光盒110，提供光源，将刻度板120的刻度121和计数型标记122投影到显示面板，所述发光盒110与所述刻度板120相对设置。
在一实施例中，刻度板120的形状为长方体薄板，刻度板120刻度121和计数型标记122的方向与刻度板长度L的方向一致。
本方案中，刻度板120形状为长方体薄板，可以减少自身占用空间减轻重量，方便使用者测量，由于刻度板120是测量长度的，所以刻度121的分布形状为长方形，刻度121和计数型标记122的方向与刻度板长度L的方向一致，可以提高刻度121对刻度板120顶面的空间利用率。
在一实施例中，计数型标记122为数字型标记123，刻度板120上的数字型标记123与投影后的数字型标记123互为镜像，投影后的数字型标记123对应观察者正视的角度。
本方案中，发光盒110上的光线经过刻度板120从而将刻度121与数字型标记123在显示面板上成像，为了方便读数，数字型标记123成像得是正像的，但投影投射出来的数字型标记123影像是颠倒的，所以刻度板120上的数字型标记123为正视角度数字型标记123的镜像，方便读数。
在一实施例中，计数型标记122位于刻度121右侧。
本方案中，通常人们阅读时从左到右进行观察，计数型标记122位于刻度121右侧，实际上镜像反射出的光线中计数型标记122位于刻度121左侧，方便观察。
在一实施例中，数字型标记123采用阿拉伯数字进行标记。
本方案中，数字型标记可以使用阿拉伯数字、罗马数字等其他数字标记。本申请采用阿拉伯数字进行标记，清楚明了。
在一实施例中，刻度板120和发光盒110材质相同，采用不透光塑料制成。
本方案中，采用不透光塑料材质制作刻度板120和发光盒110，质量较轻，抗压抗 摔能力强。
在一实施例中，刻度板120设置在发光盒110上，覆盖发光盒110的出光面；刻度板120仅在刻度121和计数型标记122区域透光。
本方案中，刻度板120覆盖发光盒110的出光面，保证光线充分照射到刻度板120，为了让刻度尺100上的刻度121和计数型标记122在玻璃基板上成像，有两种情况，一种是刻度121和计数型标记122不能透光，刻度板120的其余部分能透光，另一种是刻度121和计数型标记122能透光，刻度板120的其余部分不能透光，如果是第一种情况，那刻度121和计数型标记122呈现出来的图像就是自身的影子且是黑色的，但是由于刻度板120上只有小部分面积是刻度121和计数型标记122，其余部分透过的光线很多，有可能会反射到刻度121和计数型标记122所呈现出来的影像上，导致刻度121和计数型标记122成像不清，影响读数，而另一种情况则相反，刻度121和计数型标记122呈现出来的影像会很亮且明显，方便使用者读数。
在一实施例中，刻度板120上刻度121的宽度一致。
本方案中，刻度121一致，透过的光线宽度一致，测量准确。
在一实施例中，发光盒110包括凹槽111，刻度板120固定在凹槽111的顶部，光源固定在凹槽111的底部，光源从凹槽111的底部向凹槽111的顶部发射。
本方案中，刻度板120固定在凹槽111的顶部，光源固定在凹槽111的底部，这样的话刻度板120与光源之间存在一定间距，让光有一段传播、过渡的距离，令刻度121和计数型标记122的成像更加均匀。
在一实施例中，光源为面光源，面光源采用条形面光源。
本方案中，为了保证刻度板120上刻度121和计数型标记122的成像不被放大或缩小，确保刻度121的精确，发光盒110的光源采用面光源，面光源的所有光线都是互相平行的，可以保证刻度121和计数型标记122的成像大小不变，确保读数的精确，由于刻度板120是测量长度的，所以面光源采用条形面光源，以配合长方体刻度板120，缩减体积，减少不必要的浪费。
在一实施例中，发光盒110包括电源112、开关按钮113和凸台114，凸台114形状 为长方体，凸台114的位置在凹槽111的侧部，凸台114与凹槽111相连，电源112和开关按钮113设置在凸台114上，开关按钮113开启或关闭电源112，所述开关按钮113调节光源的强度。
本方案中，由于发光盒110形状为长方体，为了提高发光盒110的整体性，凸台114的形状也为长方体，凸台114设置在凹槽111的侧部，方便使用发光盒110固定和测量，因为在使用发光盒110测量时要保持发光盒110水平和稳定以保证刻度121成像的精准，如果手持发光盒110的话难免会倾斜或晃动，比较简单的固定方法就是将发光盒110的凸台114放在水平面上再用重物压住凸台114保证发光盒110读数时的稳定性，将电源112和开关按钮113设置在凸台114上，提高了凸台114的利用率，相应的缩减了发光盒110的体积和重量，电源112为发光盒110提供能源，令发光盒110发光，通过按压开关按钮113开启或关闭电源112，避免发光盒110一直发光浪费能源，同时通过旋转或按压开关按钮113随时调节光源的光照强度，以适应不同亮度环境下的测量，以提高测量效率。
参考图2所示，在一实施例中，发光盒110包括感光装置130，感光装置130位于凸台114表面，感光装置130根据外界光线强度自动调节光源的强度。
本方案中，在发光盒上110增加感光装置130，可以自动根据外界光线强度调整光源的强度。
在一实施例中，刻度板120可拆卸的设置在发光盒110上。
本方案中，令刻度板120可拆卸，可以在不更换发光盒110的情况下更换不同的刻度板120，而且在发光盒110光源出故障的情况下方便修理或更换。
在一实施例中，发光盒110包括环形凸台114，环形凸台114为凹槽111形成的，环形凸台114围绕在凹槽111的边缘，刻度板120与环形凸台114的顶部相连，环形凸台114的顶部与凹槽111的底部平行。
本方案中，环形凸台114由凹槽111所形成，环形凸台114的顶面是平面，可以对刻度板120起到支撑作用，与刻度板120相连令刻度板120固定的更稳定，环形凸台114的顶部与凹槽111的底部平行，由于刻度板120是与环形凸台114顶部配合的，所以刻 度板120的底部也与凹槽111的底部平行，凹槽111的底部发射的是面光源，面光源各光线互相平行，这样光线与刻度板120平面垂直，令刻度板120上刻度121的成像大小不变，读数更精准。
在一实施例中，刻度板120在安装到环形凸台114上时，刻度121和计数型标记122的位置不超过环形凸台114的内边围绕的区域。
本方案中，由于光源是从凹槽111底部发射出来的，而环形凸台114是凹槽111所形成的，如果刻度121和计数型标记122的位置在环形凸台114的顶面上那光源是照不到刻度121和计数型标记122的，因而刻度121和计数型标记122的成像就会不完整影响读数，所以刻度121和计数型标记122的位置不超过环形凸台114的内边，保证刻度121和计数型标记122成像的完整。
作为本申请的另一实施例，参考图1至图4所示，公开了一种显示面板的刻度尺100，刻度尺100包括：刻度板120，标有刻度121和数字型标记123；发光盒110，提供光源，将刻度板120的刻度121和数字型标记123投影到显示面板，所述发光盒110与所述刻度板120相对设置；刻度板120的形状为长方体薄板，刻度板120刻度121和数字型标记123的方向与刻度板长度L的方向一致。刻度板120上的数字型标记123与投影后的数字型标记互为镜像，投影后的数字型标记123对应观察者的正视角度；
刻度板120设置在发光盒110上，覆盖发光盒110的出光面；刻度板120仅在刻度121和数字型标记123区域透光。发光盒110包括凹槽111，刻度板120固定在凹槽111的顶部，光源固定在凹槽111的底部，光源从凹槽111的底部向凹槽111的顶部发射。光源为面光源，面光源采用条形面光源。发光盒110包括电源112、开关按钮113和凸台114，凸台114形状为长方体，凸台114的位置在凹槽111的侧部，凸台114与凹槽111相连，电源112和开关按钮113设置在凸台114上，开关按钮113开启或关闭电源112。刻度板120可拆卸的设置在发光盒110上。发光盒110包括环形凸台114，环形凸台114为凹槽111形成的，环形凸台114围绕在凹槽111的边缘，刻度板120与环形凸台114的顶部相连，环形凸台114的顶部与凹槽111的底部平行。刻度板120在安装到环形凸台114上时，刻度121和数字型标记123的位置不超过环形凸台114的内边围绕 的区域。
本方案中，刻度板120形状为长方体薄板，可以减少自身占用空间减轻重量，方便使用者测量，由于刻度板120是测量长度的，所以刻度121的分布形状为长方形，刻度121和数字型标记123的方向与刻度板长度L的方向一致，可以提高刻度121对刻度板120顶面的空间利用率。发光盒110上的光线经过刻度板120从而将刻度121与数字型标记123在显示面板上成像，为了方便读数，数字型标记123成像得是正像的，但投影投射出来的刻度121影像是颠倒的，所以刻度板120上的数字型标记123为正常数字型标记123的镜像，方便读数。刻度板120覆盖发光盒110的出光面，保证光线充分照射到刻度板120，为了让刻度尺100上的刻度121和数字型标记123在玻璃基板上成像，有两种情况，一种是刻度121和数字型标记123不能透光，刻度板120的其余部分能透光，另一种是刻度121和数字型标记123能透光，刻度板120的其余部分不能透光，如果是第一种情况，那刻度121和数字型标记123呈现出来的图像就是自身的影子且是黑色的，但是由于刻度板120上只有小部分面积是刻度121和数字型标记123，其余部分透过的光线很多，有可能会反射到刻度121和数字型标记123所呈现出来的影像上，导致刻度121和数字型标记123成像不清，影响读数，而另一种情况则相反，刻度121和数字型标记123呈现出来的影像会很亮且明显，方便使用者读数。刻度板120固定在凹槽111的顶部，光源固定在凹槽111的底部，这样的话刻度板120与光源之间存在一定间距，让光有一段传播、过渡的距离，令刻度121和数字型标记123的成像更加均匀。为了保证刻度板120上刻度121和数字型标记123的成像不被放大或缩小，确保刻度121的精确，发光盒110的光源采用面光源，面光源的所有光线都是互相平行的，可以保证刻度121和数字型标记123的成像大小不变，确保读数的精确，由于刻度板120是测量长度的，所以面光源采用条形面光源，以配合长方体刻度板120，缩减体积，减少不必要的浪费。
由于发光盒110形状为长方体，为了提高发光盒110的整体性，凸台114的形状也为长方体，凸台114设置在凹槽111的侧部，方便使用发光盒110固定和测量，因为在使用发光盒110测量时要保持发光盒110水平和稳定以保证刻度121成像的精准，如果 手持发光盒110的话难免会倾斜或晃动，比较简单的固定方法就是将发光盒110的凸台114放在水平面上再用重物压住凸台114保证发光盒110读数时的稳定性，将电源112和开关按钮113设置在凸台114上，提高了凸台114的利用率，相应的缩减了发光盒110的体积和重量，电源112为发光盒110提供能源，令发光盒110发光，开关按钮113开启或关闭电源112，避免发光盒110一直发光浪费能源。令刻度板120拆卸，可以在不更换发光盒110的情况下更换不同的刻度板120，而且在发光盒110光源出故障的情况下方便修理或更换。环形凸台114由凹槽111所形成，环形凸台114的顶面是平面，可以对刻度板120起到支撑作用，与刻度板120相连令刻度板120固定的更稳定，环形凸台114的顶部与凹槽111的底部平行，由于刻度板120是与环形凸台114顶部配合的，所以刻度板120的底部也与凹槽111的底部平行，凹槽111的底部发射的是面光源，面光源各光线互相平行，这样光线与刻度板120平面垂直，令刻度板120上刻度121的成像大小不变，读数更精准。由于光源是从凹槽111底部发射出来的，而环形凸台114是凹槽111所形成的，如果刻度121和数字型标记123的位置在环形凸台114的顶面上那光源是照不到刻度121和数字型标记123的，因而刻度121和数字型标记123的成像就会不完整影响读数，所以刻度121和数字型标记123的位置不超过环形凸台114的内边，保证刻度121和数字型标记123成像的完整。
作为本申请的另一实施例，参考图1至图4所示，公开了一种测量装置200，测量装置200包括刻度尺100，所述刻度尺100包括：刻度板120，标有刻度121和计数型标记122；发光盒110，提供光源，将刻度板120的刻度121和计数型标记122投影到待侧物品。
