# 奇美640x480 16bit 5.4寸LCD在mx287测试
---------------------------------------

## 配置参数

```
#define DOTCLK_H_ACTIVE 640
#define DOTCLK_H_PULSE_WIDTH  10
#define DOTCLK_HF_PORCH  16
#define DOTCLK_HB_PORCH  134
#define DOTCLK_V_ACTIVE  480

## 1. 固定刷新速率为FPS=60，调节背光亮度 PWM-功率

| PWM  |  功率(W) |
|------|----------|
|60    |   1.8    |
|65    |   1.8    |
|70    |   1.8    |
|75    |   1.8    |
|80    |   1.9    |
|85    |   2.1    |
|90    |   2.4    |
|100   |   3.2    |

## 2. 固定背光全开PWM=100，调节刷新速率 FPS-功率

| FPS  |  功率(W) |
|------|----------|
| 70   | 3.3      |
| 65   | 3.3      |
| 60   | 3.2      |
| 30   | 3.1      |
| 20   | 3.1      |
