Abstract

Embodiments of the present invention provide a display panel, its point-screen testing method, and a display device, which relate to the field of display technology. The display panel includes a display area and a non-display area, and the display area includes a plurality of data lines. The length of the area is different; the non-display area includes the point screen test terminal and the switch circuit, the point screen test terminal is used to input the point screen signal to the display panel, the switch circuit includes a plurality of connected switch units, and each switch unit corresponds to at least two The data line, wherein the point screen test terminal is connected to multiple switch units, and the point screen test terminal is also connected to the i-th switch unit through the first routing, and the i-th switch unit is the point screen test terminal among the multiple switch units The nearest switch unit. The above-mentioned display panel is used to realize image display, so as to improve the problem of low test accuracy caused by signal delay in the prior art.

Description

【Technical field】 [0001] The invention relates to the field of display technology, in particular to a display panel, a point-screen testing method thereof, and a display device. 【Background technique】 [0002] With the continuous development of display technology, special-shaped display panels have been widely used. For example, the shape of the display panel is a rounded rectangle, that is, two adjacent right-angled edges are connected by arc-shaped edges. [0003] As we all know, before the display panel is put into use, it is necessary to conduct a point-screen test on the display panel to test whether the display panel can display normally. Such as figure 1 As shown, the display panel includes a test terminal 1 and a plurality of connected switch devices 2 , the switch devices 2 are correspondingly connected to the data line Data, and the test terminal 1 is connected to the first switch device. When performing a point-screen test on the display panel, the test terminal...
