OLED displays with pins for fast mounting

It has been announced that Electronic Assembly has developed a complete range of OLED displays with pins for plug in mounting. The high contrast OLED displays also feature an extremely flat design, robust construction, and a long service life.

The OLED display family features connector pins in 2.54mm pitch. These displays can be soldered directly or plugged into socket strips. Therefore, gluing procedures the need for designing a special mounting device, and error prone cable connections should be eliminated.

Since the individual OLED pixels themselves light up, these displays do not require any additional backlighting such as LCDs. As a result, OLED displays feature a very flat design (typically 2.4mm), wide viewing angles (up to 170°), high contrasts (2,000:1), fast response times (typically 10µs) and a high overall brightness (100cd/m2).

These features, together with an extended temperature range (-40 to +80°C) and a long service life (at least 50,0000h, up to 100,000h are possible), make them particularly suitable for mounting in mobile handheld devices for robust outdoor use.

The extremely good ratio of external dimensions to the active display area helps in designing very compact devices. In addition to the display in the standard colours yellow or white on black, special designs with green, red or blue are also possible for orders of a minimum quantity of 500 pieces. The devices can be controlled via both an SPI and an I2C interface.

Electronic Assembly is also offering four model series within the OLED-family. The EA OLEDL128-6 provides a graphics display resolution of 128x64px. It is about 68mm wide and almost 48mm high. The proportion of the active display area amounts to approximately 62%. 

The display is available in three different versions. The robust ‘Allround’ version with protective glass and an integrated polariser for deep background black. The slim ‘Flat’ version without protective glass but with a component height of only 2.4mm. Finally, the elegant ‘Designer’ version without polariser for mounting behind a smoked glass pane, for example. This display version features a shiny silver background and is even brighter.

EA OLEDM128-6 is slightly smaller (55x43mm) while offering the same resolution. It is available in the ‘Allround’ and ‘Flat’. 

The display unit EA OLEDS102-6 offers a resolution of 102x64px (39x38mm), available in the ‘Allround’ and ‘Flat’.

EA OLEDM204 is a text display with either 4x20 characters or 3x20 characters as well as 2x20 characters in double font size. This display measures 61x26mm and is also available in the ‘Allround’ and ‘Flat’.

Accessories, such as a USB test board, socket strips, PCAP touch panel or resistive touch panel round off the Electronic Assembly product range.
