Embodiment 1
[0041] Such as figure 1 As shown, Embodiment 1 provides a display panel 100 , which includes: a substrate 1 , a thin film transistor layer 2 , several light emitting units 3 , an encapsulation layer 4 , a touch layer 5 and a polarizer 6 .
[0042] Wherein, the substrate 1 can be a flexible substrate, which has the function of blocking water and oxygen, and the substrate 1 can have better impact resistance, and can effectively protect the display panel 100 . The substrate 1 is made of one or more of polyimide, polycarbonate, polyethylene terephthalate and polyethylene naphthalate.
[0043] Such as figure 1 , figure 2 As shown, the thin film transistor layer 2 is disposed on the substrate 1 . The TFT layer 2 includes: an active layer 21 , a gate insulating layer 22 , a gate layer 23 , an interlayer insulating layer 24 and a source-drain layer 25 . Wherein, the active layer 21 is disposed on the upper surface of the substrate 1 and its material may be ITZO or IGZO. The mate...
Embodiment 2
[0058] Such as Figure 4 As shown, Embodiment 2 includes most of the technical features of Embodiment 1. The difference between Embodiment 2 and Embodiment 1 is that the brightness adjustment structure 8 in Embodiment 2 includes: a protrusion, which is arranged on the polarizer 6 It is disposed on the surface near the side of the substrate 1 and corresponding to the light emitting unit 3 .
[0059] Such as Figure 4 , Figure 5 As shown, in Embodiment 2, the display panel 100 further includes: a photoresist layer 9 and a through hole 10 .
[0060] Wherein, the photoresist layer 9 is disposed between the touch layer 5 and the polarizer 6 . The through hole 10 runs through the photoresist layer 9 and is opposite to the protrusion; wherein, the protrusion is filled in the through hole 10 .
[0061] In Embodiment 2, the shape of the section of the brightness adjustment structure 8 (that is, the protrusion) is arc. By setting the brightness adjustment structure 8 on the polari...
Embodiment 3
[0070] Such as Figure 7 As shown, Embodiment 3 provides a display panel. Embodiment 3 includes most of the technical features of Embodiment 2. The difference between Embodiment 3 and Embodiment 2 is that in Embodiment 3, the brightness adjustment structure 8 (ie, the convex ) has a trapezoidal cross-sectional shape. Wherein, the width of the upper base of the trapezoid is smaller than the width of the corresponding light emitting unit 3 . Embodiment 3 adjusts the thickness of the polarizer 6 corresponding to each light-emitting unit 3 by setting a brightness adjustment structure 8 on the polarizer 6 corresponding to the position of the light-emitting unit 3, and then adjusts the luminous brightness corresponding to each light-emitting unit 3, and finally improves the color. The partial phenomenon is eliminated, the display yield rate of the display panel 100 is improved, and the customer experience is enhanced.
