COLOR FILTER SUBSTRATE, DISPLAY PANEL, AND TESTING METHOD THEREOF
FIG1 is a schematic plan view of a color filter substrate according to an embodiment of the present disclosure
FIG1 is a schematic plan view of a color filter substrate according to an embodiment of the present disclosure. As shown in FIG1, the color filter substrate includes a display region R1 and a peripheral region R2' corresponding to a dummy pixel region R2 disposed around the display region. It can be understood that the display region may include a color filter layer. It can also be understood that the dummy pixel region herein is a region having a plurality of dummy pixel units of the array substrate, and the dummy pixel units of the dummy pixel region are defined by the gate lines GL and the data lines DL intersecting one other. A black matrix 11 of the color filter substrate has the light transmitting section 12 in a portion DU' of the peripheral region R2' corresponding to a dummy pixel unit DU the dummy pixel region R2. The light transmitting section includes a first set of light transmitting sections Gland a second set of light transmitting sections G2. Wherein, each light transmitting section 12 of the first set of light transmitting sections G1 is formed in a portion DU' that extends along a first side S1 of the display region and corresponds to the dummy pixel unit. The second set of light transmitting sections G2 is formed in a portion DU' that that extends along a second side S2, opposite to the first side S1, of the display region and corresponds to the dummy pixel unit. It should be noted that although in FIG1, each light transmitting section in the first set of light transmitting sections is in the same column and each light transmitting section of the second set of light transmitting sections is in the same column is for an example . Each of the light transmitting sections may not be in the same column as long as it can satisfy that each light transmitting section in each set of light transmitting sections is provided along the extending direction of the corresponding side.

['1. A color filter substrate comprising a display region and a peripheral region corresponding to a dummy pixel region around the display region, wherein a black matrix of the color filter substrate comprises a light transmitting section in a portion of the peripheral region corresponding to a dummy pixel unit, and the light transmitting section comprises a first set of light transmitting sections and a second set of light transmitting sections, wherein, each of the first set of light transmitting sections is formed in a portion that extends along a first side of the display region and corresponds to the dummy pixel unit, and each of the second set of light transmitting sections is formed in a portion that that extends along a second side, opposite to the first side, of the display region and corresponds to the dummy pixel unit.', '2. The color filter substrate according to claim 1, wherein the light transmitting section comprises an opening formed in the black matrix.']
