Fig. 2 is a schematic structural diagram of a display panel according to an exemplary embodiment of the present disclosure.
Detailed Description
The present disclosure will be described in detail below with reference to specific embodiments shown in the drawings. These embodiments do not limit the disclosure, and structural, methodological, or functional changes made by those skilled in the art according to these embodiments are included in the scope of the disclosure.
The terminology used in the present disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used in this disclosure and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

The second end 302 of the backlight 30 protrudes from the second end 102 of the filter 10 to form a second protruding portion 304. With the above arrangement, the second end 302 of the backlight 30 protrudes from the second end 102 of the filter 10 to form the second protrusion 304, so that the position where the flexible circuit board 40 and the thin film transistor substrate 20 are connected to each other can be avoided.
Optionally, the backlight 30 includes a light emitter 303, and the light emitter 303 is disposed in the second protrusion portion 304 of the backlight 30, so as to avoid a position where the flexible circuit board 40 and the thin film transistor substrate 20 are connected to each other. It is to be understood that the backlight 30 of the display panel of the present disclosure is assembled in reverse of the original backlight 92 of the display panel.
