In one embodiment, the worktable for testing the liquid crystal panel includes: a table body, an upper surface of which being formed with a mounting groove in order to form a light-transmittance region; wherein, the table body is further formed with a slot that has an opening in a side surface of the table body and that is configured to mount a lower polarizer therein so that the lower polarizer at least covers the light-transmittance region. The present disclosure also provides a test apparatus including the mentioned worktable. ## Claims ### Claim 1 A worktable for testing a liquid crystal panel, the worktable comprising: a table body, an upper surface of which being formed with a mounting groove in order to form a light-transmittance region; wherein, the table body is further formed with a slot that has an opening in a side surface of the table body and that is configured to mount a lower polarizer of the liquid crystal panel therein so that the lower polarizer at least covers the light-transmittance region; wherein the table body further comprises a clamping roller and an auxiliary roller provided respectively at opposing edges of the upper surface thereof, the auxiliary roller is configured to bear against a side edge of the liquid crystal panel, and the clamping roller is connected to a driving mechanism and is able to be driven by the driving mechanism to push an opposing side edge of the liquid crystal panel, so that the clamping roller and the auxiliary roller cooperate to clamp the liquid crystal panel therebetween. ### Claim 2 (depends on 1) The worktable of claim 1, wherein the table body is further provided with a fixing mechanism configured for fixing the lower polarizer. ### Claim 3 (depends on 2) The worktable of claim 2, wherein the fixing mechanism comprises: at least two pinholes distributed in the upper surface around the opening of the slot, and pin bolts provided in and threadedly engaged with the pinholes and configured to limit an edge of the lower polarizer. ### Claim 4 (depends on 2) The worktable of claim 2, wherein the fixing mechanism comprises: a sealing strip detachably mounted to the opening of the slot, wherein the sealing strip includes a protrusion, and the protrusion is configured to be embedded into the opening of the slot so as to limit an edge of the lower polarizer. ### Claim 5 (depends on 1) The worktable of claim 1, wherein a plurality of air holes are formed in the upper surface of the table body around an opening of the mounting groove, and the plurality of air holes are configured for connection to a vacuum source, to generate a negative pressure for fixing the liquid crystal panel by adsorption. ### Claim 6 (depends on 1) The worktable of claim 1, wherein the auxiliary roller is provided at a head of the pin bolts. ### Claim 7 (depends on 1) The worktable of claim 1, wherein the driving mechanism comprises: a base, a driving piece, and two driving air paths configured for connection to an air source; the driving piece is provided on a sliding rail provided on an upper surface of the base and is connected with the clamping roller through a connection bar; the base defines an inner chamber therein, and a piston is connected with the driving piece and is provided in the inner chamber to divide the inner chamber into two chamber sections which are respectively communicated to the two driving air paths. ### Claim 8 (depends on 7) The worktable of claim 7, wherein the connection bar is provided on an upper surface of the driving piece. ### Claim 9 (depends on 1) The worktable of claim 1, wherein a coverage area of the slot is greater than an area of the opening of the mounting groove. ### Claim 10 (depends on 1) A test apparatus for testing a liquid crystal panel, the test apparatus comprising the worktable of claim 1. ### Claim 11 (depends on 10) The test apparatus of claim 10, wherein the table body is further provided with a fixing mechanism configured for fixing the lower polarizer. ### Claim 12 (depends on 11) The test apparatus of claim 11, wherein the fixing mechanism comprises: at least two pinholes distributed in the upper surface around the opening of the slot, and pin bolts provided in and threadedly engaged with the pinholes and configured to limit an edge of the lower polarizer. ### Claim 13 (depends on 11) The test apparatus of claim 11, wherein the fixing mechanism comprises: a sealing strip detachably mounted to the opening of the slot and including a protrusion configured to be embedded into the opening of the slot so as to limit an edge of the lower polarizer. ### Claim 14 (depends on 10) The test apparatus of claim 10, wherein a plurality of air holes are formed in the upper surface of the table body around the opening of the mounting groove, and are configured for connection to a vacuum source through an adsorption air path, to generate a negative pressure for fixing the liquid crystal panel by adsorption. ### Claim 15 (depends on 10) The test apparatus of claim 10, wherein the auxiliary roller is provided at a head of the pin bolts. ### Claim 16 (depends on 10) The test apparatus of claim 10, wherein the driving mechanism comprises: a base, a driving piece, and two driving air paths configured for connection to the air source; the driving piece is provided on a sliding rail provided on an upper surface of the base and is connected with the clamping roller through a connection bar; the base defines an inner chamber therein, and a piston is connected with the driving piece and is provided in the inner chamber to divide the inner chamber into two chamber sections which are respectively communicated to the two driving air paths. ### Claim 17 (depends on 16) The test apparatus of claim 16, wherein the connection bar is provided on an upper surface of the driving piece. ### Claim 18 (depends on 10) The test apparatus of claim 10, wherein a coverage area of the slot is greater than an area of the opening of the mounting groove.
