Embodiment Construction

[0016] figure 2 It is a schematic diagram of the binary value finding algorithm described in the present invention. Such as figure 2 Shown, the present invention comprises the following steps:

[0017] Step 1. Set the normal center value of VCOM. This normal center value can be measured by related equipment (such as the equipment modeled as CA310), or directly use the VCOM value in the code provided by the IC factory.

[0018] Step 2. Write the VCOM normal center value into the IC, test its corresponding flicker value several times, and take the average value as flicker_m;

[0019] Step 3, write the value obtained after subtracting n values ​​from the VCOM central value into the IC, test its corresponding flicker value multiple times, and take its average value as flicker_1;

[0020] Step 4. Write the value obtained by adding m values ​​to the VCOM center value into the IC, test the corresponding flicker value several times, and take the average value as flicker_r;

Abstract

The invention discloses an algorithm for quickly searching for a minimum flicker value and a corresponding optimal VCOM value. The algorithm comprises the following steps of setting a VCOM normal center value; writing the VCOM normal center value in an IC, testing a flicker value corresponding to the VCOM normal center value for multiple times, and taking a mean value as flicker_m; writing a value obtained by subtracting n values from the VCOM normal center value into the IC, testing a flicker value corresponding to the value for multiple times, and taking a mean value as flicker_l; writing a value obtained by adding m values to the VCOM normal center value into the IC, testing a flicker value corresponding to the value for multiple times, and taking a mean value as flicker_r; determining a value finding direction of the VCOM value; resetting the VCOM center value; and finding the minimum flicker value according to the value finding direction judged in the step 5, wherein the VCOM value corresponding to the minimum flicker value is the optimal VCOM value. According to the algorithm, the minimum flicker value and the corresponding optimal VCOM value can be quickly searched for, so that the value finding time is greatly shortened and the production efficiency is improved.

Description

technical field [0001] The invention relates to a numerical search algorithm, in particular to an algorithm for quickly finding the minimum flicker value and the corresponding best VCOM value. Background technique [0002] At present, the way most companies find the minimum flicker value and the corresponding best VCOM value is: write the VCOM value from 00 to FF into the IC one by one, then read the corresponding flicker value through the instrument, and then from all the flicker values ​​(a supply 256) take the smallest one and read back the corresponding VCOM value. In this case, it will take a long time to find the value, seriously affecting production efficiency. figure 1 is a schematic diagram of a conventional value-finding algorithm. The value-finding algorithm in the prior art can be found in figure 1 . The value finding direction starts from VOCM of 00 and gradually increases along the direction of the arrow, which needs to be performed 256 times. Contents of...
