Abstract
The invention provides a display screen and a manufacturing method thereof as well as a touch display device, and relates to the technical field of displaying. The display screen comprises a display screen main body, wherein the display screen main body comprises an upper substrate and a lower substrate, and a black matrix positioned on the upper substrate or the lower substrate; the display screen further comprises a shading element arranged on the outer side of the display screen main body; a perpendicular projection of the shading element on the display screen main body is partially overlapped with a perpendicular projection of the black matrix on the display screen main body, so that leaking light is shaded. The shading element is arranged on the outer side of the display screen main body after the display screen main body is manufactured, and thus, a remediation measure is provided for a display screen with disqualified leaking light inspection; therefore, by the arrangement of the shading element, light leakage is avoided or light leakage can be in a bearable range; the yield of a product is increased, and waste of the cost is avoided.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a display screen, a manufacturing method thereof, and a touch display device. Background technique [0002] With the continuous development of display technology, touch display devices, as a human-computer interaction device, are increasingly used in various electronic devices. When users use touch display devices, they only need to touch the touch display with their fingers. Icons or characters on the device can realize the operation of the host. It can be seen that the wide application of touch display devices makes human-computer interaction extremely convenient. [0003] A touch display device generally includes a display screen and a touch screen superimposed together. After the display screen is manufactured, the display screen needs to be tested to check whether the display screen has light leakage and whether the light leakage is within an acceptable range. Ther...
