I tried as follows, but still can't achieve the goal:

(use-package pdf-tools
  :ensure t
  :init
  (pdf-tools-install)

  (setq pdf-sync-backward-display-action
    '(display-buffer-reuse-window (reusable-frames . t)))

  (defun th/display-buffer-in-my-pdf-frame (buffer alist)
    (if-let ((frame (car (seq-filter
                          (lambda (f) (frame-parameter f 'th/pdf-frame))
                          (frame-list)))))
    (display-buffer-use-some-frame
     buffer `((frame-predicate . ,(lambda (f)
                    (frame-parameter f 'th/pdf-frame)))))
      (display-buffer-pop-up-frame
       buffer (cons
               '(pop-up-frame-parameters (th/pdf-frame . t))
               alist))))

  (defun th/display-buffer-in-my-tex-frame (buffer alist)
    (if-let ((frame (car (seq-filter
                          (lambda (f) (frame-parameter f 'th/tex-frame))
                          (frame-list)))))
    (display-buffer-use-some-frame
     buffer `((frame-predicate . ,(lambda (f)
                    (frame-parameter f 'th/tex-frame)))))
      (display-buffer-pop-up-frame
       buffer (cons
               '(pop-up-frame-parameters (th/tex-frame . t))
               alist))))

  (add-to-list 'display-buffer-alist
               `((derived-mode . pdf-view-mode)
         th/display-buffer-in-my-pdf-frame))
  (add-to-list 'display-buffer-alist
               `((derived-mode . LaTeX-mode)
         th/display-buffer-in-my-tex-frame))
  )
