Regarding claim 1:
Hatakeyama discloses:
Claim 1
Hatakeyama
1. A head-up display system, comprising:
As seen, in, e.g., Fig. 5, this is a head-up display system
a display configured to display a first image; and
Paragraph 44: “light source panel 10”[1]
a projection screen disposed adjacent to the display and configured to let the first image to be projected thereon to form a second image,
Paragraph 49: “front windshield”
wherein the display comprises a first region adjacent to the projection screen and a second region away from the projection screen,
Shown in, e.g., Fig. 11, where some rows are closer and others further
the projection screen comprises a third region adjacent to the display and a fourth region away from the display, and
Shown in, e.g., Fig. 11, where in, e.g., Fig. 26 it can be seen that the rows in the display can correspond to rows in the projection
when the display displays the first image, a brightness difference between the first region and the second region is greater than a brightness difference between the third region and the fourth region.
Paragraph 54: “luminance…are adjusted in advance on the basis of a distance L,” or paragraph 78. So there is a difference between the first and second regions because they project a different distance L. But the second and third images are the projected images and because luminance was adjusted in the display these show similar brightness.
wherein the projection screen comprises a non-projection region and a projection region configured to let the first image to be projected thereon to form the second image, the projection region starts at a bottom border of the projection screen, and the third region and the fourth region are located in the projection region, wherein:
It can be seen in, e.g., Fig. 101, that the image is only projected over part of the windshield, which is the projection screen, so there is a non-projection region and a projection region. However, Hatekayam does not explicitly disclose that the projection region starts at a bottom border of the projection screen.
a curvature of the projection region is less than a curvature of the non-projection region
Not disclosed by Hatakeyama
wherein the display comprises a plurality of light-emitting elements and a spacer layer disposed on the plurality of light-emitting elements and having a plurality of opening respectively overlapping with the plurality of light-emitting elements, and an angle of a side wall of each of the plurality of openings of the spacer layer is different, a light path of each of the plurality of light-emitting elements is changed.
Not disclosed by Hatakeyama
Therefore Hatekayama does not disclose:

Response to Arguments
Applicant's arguments filed 11 August 2026 have been fully considered but they are not persuasive.
Applicant argued that the new language of the claims directed to the spacer layer and the side wall angle rendered the claims allowable over the prior art.
It is true this was not disclosed in the prior art relied upon in the previous rejection. However, after search and consideration, Hu has been relied upon to teach this claim element. Therefore the arguments are not persuasive in view of the new grounds of rejection.
