LUMINEQ EL240.128.45-EC Small Graphics Display

EL240.128.45-EC display

The EL240.128.45-EC thin film electroluminescent (TFEL) small graphics display utilizes Lumineq® Displays’ proprietary Integral Contrast Enhancement (ICEBrite™) technology to achieve unparalleled image quality without the use of expensive filters. This small graphics display excels in a wide range of ambient lighting environments while effectively eliminating the blooming common to other high-bright displays.
The display consists of a TFEL glass panel and control electronics connected using elastomeric interconnects into a space-saving, rugged package for easy mounting. It also includes a DC/DC converter. The EL240.128.45-EC is easily interfaced using a built-in Epson S1D13700 standard display controller. Each of the pixels has an aspect ratio of 1:1 (V:H) and is individually addressable to clearly display high information content graphics and text.

Installation and handling

Do not drop, bend, or flex the display. Do not allow objects to strike the surface of the display.
CAUTION: The display uses CMOS and power MOS-FET devices. These components are electrostatic-sensitive. Unpack, assemble, and examine this assembly in a static-controlled area only. When shipping, use packing materials designed for the protection of electrostatic-sensitive components.
CAUTION: To prevent injury in the event of glass breakage, an impact- resistant shield or a protective overlay should be used on the viewer side of the display.

Mounting TFEL displays

Properly mounted, TFEL displays can withstand high shock loads as well as severe vibration found in demanding applications. However, the glass panel used in a TFEL display will break if subjected to bending stresses, high impact, or excessive loads.
Stresses are often introduced when a display is mounted into a product. Ideally, the mounting tabs of the display should be the only point of contact with the system. Use a spacer or boss for support; failure to do so will bend the display and cause the glass to break. The instrument enclosure or frame should not flex or distort in such a way that the bending loads might be transferred to the display during use. Mounting surfaces should be flat to within ±0.6 mm (±.025″). Use all the mounting holes provided. Failure to do so will impair the shock and vibration resistance of the final installation.
The EL240.128.45-EC is a tab-mounted display. Use appropriate length standoffs to assure that screws through the mounting tabs do not introduce bending stresses into the display. Do not deflect the ECB out of its normal plane. The EL240.128.45-EC mounting tabs are designed for 3 mm screws.
WARNING: These products generate voltages capable of causing personal injury (high voltage up to 230 VAC). Do not touch the display electronics during operation.

Cable length

A maximum cable length of 600 mm (24 in.) is recommended. Longer cables may cause data transfer problems between the data transmitted and the display input connector. Excessive cable lengths can pick up unwanted EMI.

Cleaning

As with any glass or coated surface, care should be taken to minimize scratching. Clean the display glass with mild, water-based detergents only. Apply the cleaner sparingly to a soft cloth, then wipe the display. Disposable cleaning cloths are recommended to minimize the risk of inadvertently scratching the display with particles embedded in a re-used cloth. Particular care should be taken when cleaning displays with anti-glare and anti- reflective films.

Avoiding burn-in

As with other light-emitting displays, displaying fixed patterns on the screen can cause burn-in where luminance variations can be noticed. Use a screensaver or image inversion to avoid causing burn-in on the display.

Specifications

The TFEL panel is a matrix structure with column and row electrodes arranged in an X-Y formation. Light is emitted when an AC voltage of sufficient amplitude is applied at a row-column intersection. The display operation is based on the symmetric, line-at-a-time data addressing scheme.

Power

The supply voltages are shown in Table 1. All internal high voltages are generated from the display supply voltage (VH). The logic supply voltage (VL) should be present whenever video input signals are applied. The minimum and maximum specifications in this manual should be met, without exception, to ensure the long-term reliability of the display. Performance characteristics are guaranteed when measured at 25 C with rated input voltage unless otherwise specified. Beneq does not recommend operation of the display outside these specifications.

Connector

Video signals and DC power are supplied to the display through a single 24-pin, dual-row, 2 mm pitch square pin, right-angle, locking connector, such as Samtec part number EHT-112-01-S-D-RA, or an equivalent connector matching the pinouts in Table 3. The mating connector is the Samtec TCSD family of cable strips. Consult your Samtec representative for cable and connector options. Table 3. Connector pinouts J1

Dimming

The dimming control circuitry on the display allows the user to adjust the luminance from 5% to 95% of the maximum brightness.
To control the display luminance, connect a 50 kΩ variable resistor between the ground and the dimming pin (LUMA). The full resistance of 50 kΩ will result in 95% of the maximum luminance. Reducing the resistance will reduce the luminance, with the resistance of 0 Ω yielding roughly 5% of the maximum luminance.
Alternatively, an external voltage or current-mode D/A converter may be used to dim the display by sinking a maximum of 250 A for maximum dimming from LUMA to ground. When left open, the luminance will remain at the maximum level.

Table 7. Luminance control

Maximum (no resistor connected): 100 % (Default)

Maximum (50 k W resistor connected): 95 %
Minimum (0 W resistor connected): 5 % maximum
Open circuit voltage 4 V nominal
Sink current 250 mA max, Vin = 0 V
Luminance values are measured as a percentage of full-on luminance (with the

external resistor disconnected.)

Self-test mode

The display incorporates a self-test mode composed of three patterns displayed at the maximum rate for 8 seconds each and then repeated. The patterns are as follows: 1×1 checkerboard, full-on, and full-off.
The self-test mode is entered by leaving the SELFTEST pin pulled high. For normal operation, the SELFTEST pin must be pulled to a logic low.

Power-up sequence

No special power-up or video sequencing is required.

Command description

The EL240.128.45-EC display is driven by the Epson S1D13700 display controller. For details on using this controller, refer to the S1D13700F02 manual titled Hardware Functional Specification.

Required register settings and configuration items

• The SYSTEM SET command is used to configure the S1D13700 for the display.
• W/S, bit 3 of the P1 byte of the SYSTEM SET instruction, is set to 0 for a single drive panel.
• MOD, bit 7 of the P1 byte of the SYSTEM SET instruction, is set to 0 to turn off the additional output cycle of the shift clock.
• The recommended SYSTEM.SET parameter values for a frame rate of 240 Hz are (P1 through P8) in hex: 30, 07, 07, 1D, 23, 7F, 1E, 00.
• P5 must not be less than 23 to guarantee that the minimum line period requirement of the display is achieved (32.5 µs).
• The READY flag is high during extra line times, so P6 should be over 7F if the READY flag is used. After the falling edge of the READY flag, there is min. 3.5 s time to end the display memory write cycle.
• See details in the Epson S1D13700F02 Hardware Functional Specification.

Component envelope

The component envelope shown in Figure 4 illustrates the distance the components extend behind the display. Tall components do not necessarily fill this area. Beneq reserves the right to relocate components within the constraints of the component envelope without prior customer notification. For this reason, Beneq advises users to design enclosure components to be outside the component envelope.
An air gap of at least 5 mm is recommended to dissipate heat from display components. Device designers will need to consider their specific system requirements to determine the necessary spacing.
