5.4 PANEL SPECIFICATION (AU EN05/ QDI L07/ Hydis E13-100/LG E01) 5.4.1 Panel Feature

AU EN05

–This specification applies to the 17.0 inch Color TFT-LCD Module M170EN05

–The display supports the SXGA (1280(H) x 1024(V)) screen format and 262k colors(RGB 6-bits data) –All input signals are 2 Channel LVDS interface compatible

–This module does not contain an inverter card for backlight

QDI L07

–High aperture panel; high-brightness or low power consumption –Brilliant and high contrast image

–Small footprint and thin shape –SXGA resolution

–LVDS interface

–Low power consumption –Wide viewing angle

Hydis E13-100

–LVDS interface with 2 pixels / clock –High-speed response

–Lower power consumption

–6 bits(FRC) colors, display 16,194,227 –Incorporated edge type back-light(Four lamps)

–High luminance and contrast ratio, Lowe reflection and wide viewing angle –DE(Data Enable) & H-Sync & V-Sync mode

LG E01

–This TFT-LCD has a 17.0 inch diagonal measured display area with SXGA resolution(1024 vertical by 1280 horizontal pixel array)

–8-bit gray scale signal for each dot, thus, presenting a palette of more than 16.2M colors with FRC. –Lowe power, high speed ,low EMI.

–Thin thickness, wide viewing angle, lower power are critical factors and graphic displays.

1)MCU initialize.

2)Is the eeprom blank?

3)Program the eeprom by default values.

4)Get the PWM value of brightness from eeprom. Check the pin PANEL1 and PANEL2 to tell which panel to get with it.

5)Is the power key pressed?

6)Clear all global flags.

7)Are the AUTO and SELECT keys pressed?

8)Enter factory mode.

9)Saving the power key status into eeprom. Turn on the LED and set it to green color. Scalar initializes.

10)In standby mode?

11)Update the lifetime of back light.

12)Check the analog and digital port, are there any signals coming?

13)Does the scalar send out a interrupt request?

14)Wake up the scalar.

15)Are there any signals coming from analog or digital port?

16)Display " No Input Signal " message. And go into standby mode after the message disappear.

17)Program the scalar to be able to show the coming mode.

18)Process the OSD display.

19)Read the keyboard. Is the power key pressed?
