the embodiment of the present disclosure provides a transparent display panel, which is described in detail below with reference to fig. 1.
As shown in fig. 1, fig. 1 is a schematic structural diagram of a transparent display panel 100 according to an embodiment of the present disclosure, where the transparent display panel 100 includes a plurality of pixel units arranged in an array, each of the pixel units includes a light-emitting sub-area 112 and an external light-transmitting sub-area 111, the light-emitting sub-area 112 is used for normally displaying a light-emitting effect, and the external light-transmitting sub-area 111 is used for providing a path for external light to penetrate when the transparent display panel 100 does not perform a display effect, so as to achieve a transparent display effect of the transparent display panel 100.
The light-emitting sub-area 112 includes a plurality of sub-pixel opening portions arranged at intervals, and the sub-pixel opening portions having the same color in the adjacent pixel units are connected with each other, and the sub-pixel opening portions are used for configuring different light-emitting colors for the sub-pixels through an ink-jet printing process, and under the condition that the accuracy of the ink-jet printing process is not changed, the sub-pixel opening portions are connected with each other, so that the areas of the sub-pixel opening portions and the light-emitting sub-area are increased, and a plurality of sub-pixels can be printed at the same time, thereby reducing the difficulty of the ink-jet printing process.

Preferably, the minimum distance between adjacent sub-pixel opening portions in the same pixel unit is equal, that is, the minimum distance between the first sub-pixel opening portion 114 and the second sub-pixel opening portion 115 is equal to the minimum distance between the second sub-pixel opening portion 115 and the third sub-pixel opening portion 116.
In this embodiment, the light-emitting sub-area 112 further includes a pixel circuit portion 113, and the pixel circuit portion 113 is disposed in other areas except the sub-pixel opening portion in the light-emitting sub-area 112.
