The invention relates to a cover pane (10) configured to cover at least one display device, the cover pane having an outer panel and an inner panel, the inner panel facing the display device and comprising an opaque coating layer. The outer panel comprises: a) at least one display area (1) allowing visualization of at least a portion of the screen of the display device, said display area having a peripheral P display; b) at least one opaque region (2) corresponding to said opaque coating layer and directly surrounding at least 10% to 100% of the display perimeter, said opaque region having an average surface roughness defined by an opaque arithmetic amplitude Ra (op). The outer panel further comprises at least one textured area (3) covering between 0.5% and 99.5% of the opaque area, said textured area directly surrounding at least 5% of the display perimeter and having an average surface roughness defined by a texturing arithmetic amplitude Ra (tex). The absolute difference between Ra (op) and Ra (tex) is at least 25 nm (I Ra (op)-Ra (tex) | > = 25 nm).
本发明涉及一种被配置成覆盖至少一个显示器装置的盖板玻璃板(10),该盖板玻璃板具有外板面和内板面,其中,内板面面向显示器装置并且包括不透明涂料层。外板面包括:a)至少一个显示器区域(1),该至少一个显示器区域允许可视化显示器装置的屏幕的至少一部分,所述显示器区域具有周界P显示器;b)至少一个不透明区域(2),该至少一个不透明区域对应于所述不透明涂料层并且直接包围至少10%至100%的显示器周界,所述不透明区域具有由不透明算术幅值Ra(op)定义的平均表面粗糙度。外板面进一步包括覆盖介于0.5%至99.5%之间的不透明区域的至少一个纹理化区域(3),所述纹理化区域直接包围至少5%的显示器周界,并且具有由纹理化算术幅值Ra(tex)定义的平均表面粗糙度。Ra(op)与Ra(tex)之间的绝对差值为至少25nm(I Ra(op)‑Ra(tex)│≥25nm)。
