Alignment device and alignment method for display panel

Abstract

The invention discloses an alignment device and an alignment method for a display panel, and relates to the field of display panel manufacturing. The alignment device for a display panel includes a light source and a light adjustment element, the light source is arranged on one side of the light adjustment element, the light adjustment element includes a plurality of light-shielding areas and a plurality of light-transmitting areas, the The light-shielding regions and the light-transmitting regions are arranged alternately along the length direction of the light-adjusting element, the shape of the light-transmitting regions is consistent with the shape of the electrodes on the substrate to be aligned, and between the plurality of the light-transmitting regions The relative position of the electrode is consistent with the relative position between a plurality of electrodes on the substrate to be aligned. The invention can accurately align the gold fingers on the flexible printed circuit board with the electrodes on the substrate, so that the common electrode voltage written into the drive chip in the manual pressing mode can be applied to the subsequent process, thereby effectively suppressing the common electrode voltage deviation caused by the common electrode voltage. Display screen flickering problem caused by moving.

Description

technical field [0001] The invention relates to the field of display panel manufacturing, in particular to an alignment device and an alignment method for a display panel. Background technique [0002] The driving circuit part of the display panel is mainly composed of gate lines and data lines. When the gate line is at a high voltage, the thin film transistor is turned on, and the data line charges the pixel electrode; when the gate line is at a low voltage, the thin film transistor is turned off, the data line stops charging the pixel electrode, and the storage capacitor supplies power to the pixel electrode. [0003] Wherein, a voltage drop of a certain amplitude, ie, ΔVp, will appear on the data line under the coupling action of the common electrode. Affected by △Vp, the positive and negative voltages of the data lines are uneven, which in turn causes the screen to flicker on the display panel. [0004] The current solution is to use a jig to manually press the flexibl...
