Fig. 1 is a block diagram of an image printing apparatus in an embodiment, the image printing apparatus includes a display 120 and an optical filter assembly, the display 120 is provided with an array light source 121, the optical filter assembly includes a first substrate 101, a first photoresist layer 102 and a color film layer 103 which are stacked, the first photoresist layer 102 is disposed on a first side of the first substrate 101, and the first photoresist layer 102 includes a light-transmitting area corresponding to the array light source 121 and a first black matrix 104 surrounding the light-transmitting area; the color film layer 103 is located on a side of the first photoresist layer 102 away from the first substrate 101, and the color film layer 103 includes a plurality of color resistance units 105 and a second black matrix 106, where each color resistance unit 105 is respectively disposed in one-to-one correspondence with each light transmission region in the stacking direction, and the second black matrix 106 and the first black matrix 104 are correspondingly disposed in the stacking direction.
Light emitted by the display 120 is irradiated on the optical filter assembly, and is emitted from one side of the color film layer 103 to the first substrate 101, light emitted to the second black matrix 106 is blocked, and the rest of light is emitted through the color resistance unit 105 in sequence. Since the color resistance units 105 are arranged in an array, each color resistance unit 105 is separated by the second black matrix 106, thereby avoiding light mixing between the color resistance units 105. It is understood that the color resistance unit 105 in the color film layer 103 is used to generate a plurality of color channels through which light can form a pixel unit, and when light passes through the color resistance unit 105, colors of the channels are overlapped, so that various colors which can be perceived by human vision can be generated.
Further, the light enters the first photoresist layer 102 through the color resistance unit 105, and a first black matrix 104 is disposed in the first photoresist layer 102, where the first black matrix 104 is used to prevent the light incident into the first photoresist layer 102 from scattering to an adjacent region, so that the light is emitted to the first substrate 101 only through the light-transmitting region. Since the light-transmitting regions of the first photoresist layer 102 correspond to the array light sources 121, that is, the light-transmitting regions are also arranged in an array, the first photoresist layer 102 emits multiple light beams to the first substrate 101. The first black matrix 104 and the second black matrix 106 are correspondingly arranged in the stacking direction, thereby realizing a multi-layer filtering effect to further improve the light mixing defect, reduce the mutual interference between adjacent pixels and make the image clearer.
The first substrate 101 serves as a supporting structure for the first photoresist layer 102, and a transparent material may be used to transmit each light emitted from the first photoresist layer 102. The light transmitted through the first substrate 101 can be directly mapped onto the photographic paper without forming a plurality of optical fiber paths by using a plurality of groups of optical fiber materials, so that each path of light transmitted by the first substrate 101 is output, the optical fiber materials are saved, and the condition that the optical fibers are aligned with each path of light to ensure the output quality of the light is avoided.

It is understood that the first black matrix 104 in each layer of the first photoresist layer 102 blocks light from scattering from the side, thereby achieving a multi-layer filtering effect, so that light can only exit from the light-transmitting region in the first photoresist layer 102. The first photoresist layer 102 is made of a photoresist material, which can increase light transmittance.
Fig. 2 is only used to exemplarily show the stacking configuration of the first photoresist layer 102 when it is a multi-layer composite structure, and is not used to limit the specific number of layers to two, and actually it is at least not less than 2.
