A substrate, a panel, a detection device and an alignment detection method are provided. The substrate includes first signal connection pins arranged in parallel side by side and at least one first alignment detection pin, wherein the at least one first alignment detection pin is located on at least one side of the first signal connection pins in an arrangement direction of the first signal connection pins, and arranged in parallel with the first signal connection pins.

Substrate, panel, detection device and alignment detection method

A test circuitry and a method for testing the same and a test system are provided. The test circuitry includes: a test signal input end, configured to input an initial test signal; a signal output end, configured to output a target test signal; and a signal shaping circuitry coupled to the test signal input end and the signal output end, configured to remove a noise signal from the initial test signal to obtain the target test signal.

Test circuitry and method for testing the same, test system

A set of measurement voltages having different voltage values are subsequently inputted to a measurement voltage input terminal of the pixel driving circuit, a light emitting state of a light emitting device under each measurement voltage is detected, and it is determined whether a storage capacitor in the pixel driving circuit is normal based on the light emitting state of the light emitting device.

Capacitor detection method and pixel driving circuit

The present application discloses a circuit board and a method for manufacturing the same, and a terminal test device. The circuit board includes a base substrate, and a plurality of conductive lines on the base substrate, each of the plurality of conductive lines having one end configured to be connected with a signal output bus of a signal generator and the other end configured to be connected with a terminal. A fuse is connected in series in each conductive line, and a breaking current IT of the fuse, a maximum operating current I of the conductive line and a fault current IF of the conductive line satisfy: I&#x3c;IT&#x2264;IF, where the breaking current IT of the fuse is a minimum current that causes the fuse to open.

Circuit board and method for manufacturing the same, terminal test device

Embodiments of the present disclosure provide a test circuit, a test method, a display panel and a display apparatus. Each of the signal input terminals may input a plurality of signals in a time division multiplexed manner, and in turn may be controlled by the corresponding switches to form a plurality of signal lines, a signal flow of the plurality of signal lines are totally different from each other under control of the switches. For example, one of the signal lines may function as a signal input line, and the other one of the signal lines may function as a signal input line for other specific testing, such as aging process so as to input signals different from the normal turn-on state signals. Consequently, by controlling the corresponding switches through the control signal terminals so that different input signals pass through different signal lines into the display panel to meet testing requirements of normal turn-on state testing, aging process and so on for the display panel. With respect to the prior art, the testing signals may be input without passing through a shift register unit, which avoids damage of a specific testing signal such as aging signal on the shift register unit and ensure a normal displaying function of the display panel.

Test circuit, test method, display panel and display apparatus

The present disclosure provides a device and a method for transferring a display panel. The device includes a carrier configured to transfer the display panel, and a light-shielding plate secured onto the carrier and configured to shield a display region of the display panel when the display panel enters an irradiation region.
