Abstract: The present invention discloses a display substrate, a method of manufacturing the same, and a display apparatus. The display substrate comprises a substrate body and a support spacer provided on the substrate body. In the display substrate, a contact surface between the support spacer and the substrate body is configured to be a non-flat surface. On one hand, the non-flat contact surface has a larger contact area than a flat contact surface and increases an adhesion force between the support spacer and the substrate body. Thereby, it can prevent the support spacer from being separated from the substrate body. On the other hand, the non-flat contact surface can hinder the movement of the support spacer relative to the substrate body in some directions. Thereby, it also can prevent the support spacer from being separated from the substrate body.
Abstract translation: 本发明公开了一种显示基板及其制造方法以及显示装置。 显示基板包括基板主体和设置在基板主体上的支撑间隔件。 在显示基板中，支撑间隔件和基板主体之间的接触面被构造为非平坦表面。 一方面，非平坦接触表面具有比平坦接触表面更大的接触面积，并且增加了支撑间隔物和基底体之间的粘附力。 由此，能够防止支撑间隔件与基板体分离。 另一方面，非平坦接触表面可以阻碍支撑间隔件在某些方向上相对于基体的移动。 由此，也可以防止支撑间隔物与基板本体分离。

Abstract: A spacer supportability evaluation method and device as well as a computer readable storage medium are provided. The method includes acquiring initial distribution images of spacers and corresponding support pads on a substrate, performing binary grayscaling processing to obtain distribution images of spacers and corresponding support pads, obtaining two binary matrices according to the distribution images, subjecting the two binary matrices to convolution in a spatial domain or to multiplication in a frequency domain to obtain an equivalent support matrix, calculating a number of elements in the equivalent support matrix whose values are a first value to obtain a number of supported pixels. The supportability of spacers is evaluated by acquiring parameters or design drawings of the spacers to calculate suitable size and positional arrangement of each spacer, improving the supportability of spacers and keeps the cell gap of the liquid crystal cell stable and uniform.
