Abstract
This application discloses a lookup table creation method, a display panel manufacturing method, and a display device. The lookup table creation method includes: forming different photoresist layers; baking the photoresist layers; measuring the film thicknesses of the photoresist layers to acquire a curve chart of film thickness varying with time; and creating a lookup table according to the curve chart.
Claims15
A lookup table creation method, the creation method comprising:
- correspondingly and respectively forming different types of single-layer photoresist layers on multiple mother glass substrates;
- baking the photoresist layers on the mother glass substrates at preset temperature;
- measuring a film thickness of each photoresist layer after a preset time interval to acquire a curve chart of the film thickness varying with baking time of the photoresist layer;
- and
- fitting and correcting the curve chart to create a lookup table.

A display panel manufacturing method, which adopts a lookup table created by adopting the lookup table creation method, the method comprising:
- forming a first substrate provided with different types of photoresist layers on a glass substrate by adopting different mask manufacture procedures;
- acquiring a setting order and baking time of the different types of photoresist layers;
- calculating a box thickness of a display panel according to the setting order and the baking time;
- controlling a drop-in volume of liquid crystals according to the box thickness;
- and
- aligning the first substrate with a second substrate to form the display panel.
