Display device, touch display panel, and touch panel and manufacturing method therefor
The present invention relates to the technical field of display, and relates to a display device, a touch display panel, and a touch panel and a manufacturing method therefor. The touch panel of the present invention may comprise a substrate, a touch layer, and a light shielding layer, the touch layer being provided on one side of the substrate. The light shielding layer and the touch layer are provided on the same side of the substrate; the light shielding layer is annular and surrounds the touch layer.
1 . A touch display panel, comprising:
a touch panel, wherein the touch panel comprises: a base substrate; a touch layer, provided on a side of the base substrate; and a light shielding layer, provided on an identical side of the base substrate with the touch layer, wherein the light shielding layer is annular and surrounds outside the touch layer, the light shielding layer comprises a light transmitting portion in a logo graphic, the light transmitting portion comprises light transmitting holes distributed in an array, and an aperture ratio of the light transmitting portion satisfies the following formula:

where T is the aperture ratio, N is the number of light transmitting holes in the light transmitting portion, D is a diameter of any of the light transmitting holes, and A is an area of an orthogonal projection of the light transmitting portion on the base substrate; and
a display substrate, provided on a side of the light shielding layer away from the base substrate, wherein the display substrate has a first display region and a second display region located outside the first display region, an orthographic projection of the first display region on the base substrate is located within a range surrounded by the light shielding layer, and an orthographic projection of the second display region on the base substrate at least partially coincides with the orthographic projection of the light transmitting portion on the base substrate,
wherein the light transmitting holes penetrate through the light shielding layer in a direction perpendicular to the base substrate to allow light to pass through,
wherein a distance between two adjacent light transmitting holes having no light transmitting hole disposed therebetween is smaller than an aperture of any of the light transmitting holes, to avoid failure to display clear and variable logo graphics due to the light transmitting holes being too sparse.
2 . The touch display panel according to claim 1 , wherein the display substrate comprises:
a driving backplane;
a light-emitting device layer, provided on a side of the driving backplane facing the touch panel and comprising a plurality of light-emitting devices, wherein the plurality of light-emitting devices are provided in both the first display region and the second display region.
3 . The touch display panel according to claim 1 , wherein the display substrate comprises:
an array substrate;
a liquid crystal layer, provided on a side of the array substrate close to the touch panel;
a color film substrate, provided on a side of the liquid crystal layer close to the touch panel, wherein the color film substrate comprises a plurality of filter parts, and the plurality of filter parts are provided in both the first display region and the second display region.
4 . A display device, comprising:
the touch display panel according to claim 2 ; and
a housing, provided outside the touch display panel, wherein the light shielding layer is located in the housing, the housing has a light transmitting region, and orthographic projections of the light transmitting region and the light transmitting portion on the substrate at least partially coincide.
