1. GENERAL DESCRIPTION

1.1 Product Overview

The LS1330I01-E-V1 is a color active matrix TFT LCD module using amorphous silicon (a-Si) TFTs as active switching devices. This module has a 13.3-inch diagonally measured active area with WUXGA resolutions (1920 horizontal by 1200 vertical pixel array). Each pixel is divided into RED, GREEN, BLUE dots which are arranged in a vertical stripe. This module can display 8-bit colors with a color gamut of sRGB 100%. The TFT-LCD panel used for this module is a low reflection and higher color type.

1.2 Module Construction

The module type is specified as COG+B/L+PCBA:

• COG (Chip-On-Glass): The driver IC is mounted directly on the LCD glass substrate.
• B/L (Backlight): An integrated LED backlight unit.
• PCBA (Printed Circuit Board Assembly): The main interface and control board.

8. TIMING CHARACTERISTICS

8.1 Basic Timing (DE Only Mode)

Note: The above is optimized setting.

8.2 eDP Rx Interface Timing

8.3 HPD & AUX Characteristics

9. POWER SEQUENCE

To prevent latch-up or DC operation, the power on/off sequence must be followed as shown in Figure 18.

Key Timing Requirements:

• 0.5ms ≤ T1 ≤ 10 ms
• 0ms < T2 ≤ 200 ms
• 0ms < T3 ≤ 200 ms
• T4+T5+T6+T8 > 80ms
• 0ms < T7 ≤ 50ms
• 50ms < T8
• 0ms < T9
• 0ms < T10 < 500 ms
• 0.5ms ≤ T11 ≤ 10 ms
• 500ms ≤ T12
• 0ms < T13
• 0ms < T14
• 0ms < T15
• 0ms < T16
• 0.5ms ≤ T17
• 0.5ms ≤ T18

Critical Notes:

1. When V_DD is 0V, keep input signals low or high impedance.
2. Do not keep interface signal high impedance when power is on. Backlight must be turned on after power for logic and interface signals are valid.

Specific Logic Power Ramp (T11):

• T11 = T20 + T21 + T22
• 0.5ms ≤ T11 ≤ 10ms
• T21 ≥ 0.225ms

10. ELECTRO-OPTICAL CHARACTERISTICS

10.1 Measurement Conditions

Measured in a dark room (≤1 lux) at 25±2°C, using a luminance meter system (PR730&PR810) at a distance of 50cm from the LCD surface with viewing angles θ and Φ equal to 0°. The backlight operates for 30 minutes prior to measurement. V_DD = 3.3±0.3V. Optimum viewing direction is 6 o'clock.

10.2 Optical Specification Table

Notes:

1. Viewing angle where contrast ratio > 10 or > 100.
2. CR = Luminance(White) / Luminance(Black).
3. Center luminance of white defined as average of 5 points.
4. Uniformity ΔY = Min Luminance / Max Luminance across measured points.
5. Crosstalk measured per Figure 11.
