In the backlight 21, the light sources 211 in a linear, dot or other shape are uniformly distributed on the transparent substrate according to a certain regular sequence, and natural light can pass through the transparent substrate of the non-light source part to form a backlight with a light source and natural light separated from each other without interference. The light sources 211 are uniformly distributed, and are linear, point or other shapes, and the natural light can normally pass through the transparent substrate without light source, and is the background environment display channel 212.
Optionally, the color filter 29 is used only in the L CD mode, and is composed of four color blocks, namely, RGB tricolor color blocks 291 and transparent color blocks 292, where the distribution rules of the RGB tricolor color blocks 291 and the transparent color blocks 292 correspond to the distribution rules of the light sources 211 of the backlight, where the RGB tricolor color blocks 291 correspond to linear, dotted or other shapes of the light sources 211 in the backlight, and the transparent color blocks 292 correspond to the background environment display channels 212 without light source parts in the backlight, and are separated from each other and do not interfere with each other.
The liquid crystal display panel 2 controls the on-off of the RGB light by using the liquid crystal layer 26 to form an image display pixel unit A; and controlling the on-off of the background environment natural light of the backlight transparent substrate without the light source part by using the liquid crystal layer 26 to form a background environment display pixel unit B.

The technical solutions of two specific embodiments provided by the present invention will now be described in detail with reference to the accompanying drawings.
Example one
The liquid crystal display panel 2 adopts an L CD mode, the backlight 21 is a linear light source 211, the resolution is 2 x m columns and n rows, the pixel units in odd columns of the 1 st column, the 3 rd column to the 2 x m-1 st column are image display pixel units A, and the pixel units in even columns of the 2 nd column, the 3 rd column to the 2 nd x m column are background environment display pixel units B.
Accordingly, the transparent substrate in the backlight 21 is equally divided into 2 × m columns, and the linear light sources 211 are embedded in the odd-numbered columns equally divided into 2 × m columns of the transparent substrate to provide light sources for image display. The even columns of the transparent substrate 2 are equally divided into m columns and are the background environment display channels 212 through which natural light can normally pass. The linear light source and the natural light are mutually isolated and do not interfere with each other.
Accordingly, the portion of the color filter 29 corresponding to the RGB color patches 291 is collinear with the line light source 211, and the portion of the color filter corresponding to the transparent patch 292 is collinear with the background environment display channel 212.
Correspondingly, the liquid crystal layer 26 controls the on-off of the light of the three primary colors of RGB to form an image display pixel unit a, and the liquid crystal layer 26 controls the on-off of the background environment natural light of the backlight transparent substrate without a light source to form a background environment display pixel unit B.
The driving chip 1 receives RGBA driving data of m columns and n rows, the driving data includes driving data of k rows in the driving data, as shown in fig. 3, the driving data of k rows in j column (0< j < m +1,0< k < n +1), and the corresponding opacity value a (alpha) value is 0%, the driving chip 1 drives the image display pixel unit a3 in k rows in (2 x j-1) th column of the liquid crystal display panel 2, so that the RGB primary color light of the image display pixel unit cannot pass through, and black is displayed. Meanwhile, the driving chip 1 drives the background environment display pixel cells B3 in the k (2 × j) th column of the liquid crystal display panel 2 to allow 100% of the background environment natural light corresponding to the pixel cells to pass through, so as to display the background environment of the liquid crystal display panel 2.
The driving chip 1 drives the image display pixel cells a1 of the k-th column (2 x j-1) of the liquid crystal display panel 2 to pass through the three primary colors of RGB of the image display pixel cells to display a desired color, and the opacity value of the image display pixel cells is 100%. Meanwhile, the driving chip 1 drives the background environment display pixel cells B1 in the k-th column (2 × j) of the liquid crystal display panel 2, so that the background environment natural light corresponding to the pixel cells cannot pass through, and black is displayed.
In the driving data, the opacity value a (alpha) of the driving data of the j-th column k-row (0< j < m +1,0< k < n +1) is greater than 0% and less than 100%, the driving chip 1 drives the image display pixel unit a2 of the liquid crystal display panel 2 (2 x j-1) th column k-row to allow the RGB three primary colors of the image display pixel unit to pass through to display a desired color, and the opacity value of the image display pixel unit is a. Meanwhile, the driving chip 1 drives the background environment display pixel cells B2 in the k-th column (2 × j) of the liquid crystal display panel 2 to make the background environment natural light corresponding to the pixel cells pass through at a rate of (100-a)%.
And sequentially driving each row of pixel units of the liquid crystal display panel 2, displaying images through each image display pixel unit A, and simultaneously setting a background environment display pixel unit B adjacent to the image display pixel unit A to be closed, so that natural light cannot pass through, and the influence of the natural light on image display is avoided. And if the image display pixel unit A is in the area without image display, closing the image display pixel unit A, and simultaneously, setting a background environment display pixel unit B adjacent to the image display pixel unit A to be opened, so that natural light passes through and the background environment is displayed. Between the image display area and the non-image display area, the image display pixel unit A and the adjacent background environment display pixel unit B are both opened, the light of the display image and the light of the background environment are mixed, and the virtual image and the background environment are displayed on the liquid crystal display panel from weak to strong in a natural transition mode.
Example two
The liquid crystal display panel 2 adopts an O L ED or Micro-L ED mode, the backlight 21 is a point light source 211, the resolution is m columns and 2 x n rows, the pixel units of the odd rows of the 1 st row and the 3 rd row to the 2 x n-1 st row are image display pixel units A, and the pixel units of the even rows of the 2 nd row and the 3 rd row to the 2 x n th row are background environment display pixel units B of the liquid crystal display panel.
Accordingly, the transparent substrate in the backlight 21 is divided into 2 × n rows, and the dot-shaped light sources 211 are embedded in the odd-numbered rows of the transparent substrate divided into 2 × n rows to provide light sources for image display. The transparent substrate 2 is divided into n rows with even number of rows as background display channels 212, and natural light can normally pass through. The point light source and the natural light are mutually isolated and do not interfere with each other.

Meanwhile, the driving chip 1 drives the background environment display pixel cells B3 in the jth column (2 × k) of the liquid crystal display panel 2 to allow 100% of the background environment natural light corresponding to the pixel cells to pass through, so as to display the background environment of the liquid crystal display panel.
