这段代码可以优化的地方比较多，建议按照以下几个方面进行调整：

1. 将重复的代码片段提取出来，封装成函数，提高代码复用性和可读性；
2. 尽可能地使用 switch-case 语句替换 if-else 语句，提高代码执行效率；
3. 对于需要频繁操作的字符串拼接操作，可以使用 sprintf 函数来代替，提高代码执行效率。

下面是一个可能的优化版本：

调用方式如下：

for (int i = 0; i < DBData.size(); i++) {
    if (DBData[i] >= RT1064KZZ_GL1_ALM && DBData[i] <= RT1064KZZ_KZHL && DBData[i] != RT1064KZZ_MODE &&
        DBData[i] != RT1064KZZ_UAB_CH && DBData[i] != RT1064KZZ_UBC_CH && DBData[i] != RT1064KZZ_FBS &&
        DBData[i] != RT1064KZZ_FBS_MODE) {
        draw_LCD(i, isDraw, val, gapid, bit);
    } else {
        draw_LCD(i, isDraw, val, gapid, bit);
    }
